EveningStar.io
EveningStar.io is a cryptocurrency information aggregator that a few friends and I put together last year. It has been a fun side project and has 200+ feeds pulling information from thousands of news sources on the web. We have about 3,000 registered users.
The idea was to have a one-stop shop for all things cryptocurrency, with news, real-time pricing, events, research articles, portfolio tracking, wallet tracking and other features. A group of friends and I originally built this for ourselves and decides to launch it to the public when cryptocurrency started getting a large following. The site is on autopilot now and has 200+ feeds integrated into it. We have 3,000+ users and well over a million pageviews since August 2017 with no advertising.
This was a really fun project in that we took an idea and making it tangible product in a few months, all the way from the logo to the finished product. It uses a completely custom WordPress backend and is fully automated (other than the featured news, which admins can do by 'favoriting' newsworthy stories). This project is a hobby of mine and nothing more.

Blue Cross Blue Shield App
Blue Cross Blue Shield Member Journey App
I helped a local agency develop a new insurance app that helps onboard patients by taking them on a 'customer journey' showcasing all of the features, benefits and advantages to using their insurance products and services. The app was developed to be used by sales and onboarding specialists on iPads, to help show potential customers benefits and features without handing them a packet of paper.
I helped develop the awesome designs into usable, interesting screens that a user can easily navigate. The client wanted it to help onboard prospective and new customers and show them visually different aspects of the product. They wanted EVERYTHING to have an animation, nothing to be 'static' and it to feel very fluid throughout all the interactions. Did I mention the tight deadline?
Boostrap, Angular.js and GSAP helped me bring the designs to life and add lots of cascading animations, smooth scrolling and transitions. We made it fast, fun, and made everything dance together. Now their team can explain the products and easy enough that the customer can browse the options themselves. In the end I think the product turned out great and the client loved it. And we met their deadline.

Custom Real-time Dashboards
I build custom real-time dashboards with at-a-glance weather radar, calendars, traffic, stock quotes, 7 day forecast and can integrate any API or feed so you have a constant pulse on the data you need to operate. I use the screens from old laptops and a Raspberry Pi to build a stationary, standalone, on-all-the-time dashboards.

NPSP25 Website
The New Personality Self Portrait is a best-silling book that is celebrating its 25th year in production. We created an awesome online personality test that users can take to gauge how their personality traits compare to others that have taken the test. The goal was to make an online version of their test, and automatically calculate not only their individual scores, but produce charts and documents related to their score. This was one of the most fun projects to work on because its so unique yet impactful.
You may have taken a personality quiz at your doctors office or in school when you were younger. Remember adding up all your scores and trying to look at a gauge after a boring multiple choice test? We wanted to change that by creating an easy to use (anywhere) test that was also a little bit different than all the competitors. We needed to make sure it was fast, discreet and users could start and stop their test whenever they want.
For payments, we integrated Stripe and Paypal - users can buy as many tests as they want and current users can 'invite' their friends and family also. After integration of the custom, mobile-friendly quiz we built a simple backend where users can see their test results, export PDFs, research anbd also invite users if they want. We also have abandonded cart emails setup that send users discounts to push conversions.

Red Tuna Shirt Club
RedTunaShirtClub.com is an awesome subscription based t-shirt company catering towards fishing enthusiasts. They came to me in 2015 wanting to completely revamp their website - the goal was to streamline their custom management process, automate their fulfillment and overall make it easy for them to handle day-to-day operations of their website.
We essentially created a custom CRM for them in the backend, complete with membership and subscription management, inventory management and a slew of other time-saving functions. This helped save them time and allowed them to focus on marketing. We created scripts and logic that automatically charge and generate orders for customers based on their selections - then we integrated the fulfillment centers API to automatically fulfill the orders. Autopilot is awesome. We also integrated not only the fulfillment centers API, but also the PayPal Pro API to handle single and recurring payments. We also created custom abandonded cart emails, promo codes, referral codes, gift certificates and other conversion optimizations.
No more spreadsheets, digging into databases and trying to juggle managing customers, orders, subscriptions, promo codes, gift certicates AND making sure all the order get fulfilled. Now they can manage everything in one place, and also know that orders automatically go out to customers, correctly.

The client submitted this review online.
Please describe your company and your position there.
I am a part owner of an industrial distribution company in Houston Texas.
For what projects/services did your company hire Raven Digital?
We hired Raven Digital to help us with designing our Website.
What were your goals for this project?
We wanted a LEGIT, professional website that encapsulated everything we do. In order to compete with the big dogs in our industry our #1 priority was to have a strong internet presence, at least when you are googling in the Houston area.
I have seen other web sites of small businesses and while they are helpful, I really wanted my website to stand out and to feel just as professional as the big timers in our industry.
How did you select this vendor?
I spoke with 3 or 4 web designers before choosing Cal at Raven Digital. He has positive energy, and was eager to help my business grow, get our name out there in the internet world.
You can tell he loves his profession to help his customers succeed. He was thorough in getting to know exactly what our business entailed, in order to capture it all on our website.
Describe the project and the services they provided in detail.
Raven Digital designed our web page beautifully. That is all we have done thus far. With new 2020 goals we will be meeting with Cal to grow our website and maybe start an E-Commerce, which would be huge for our line of work!
What was the team composition?
Cal is the only guy on the team, I was in contact with. He was very communicative which I appreciated so I only had to deal with one person. It was easier to meet with him and have one person focus in our company and get to know what we do.
Can you share any information that demonstrates the impact that this project has had on your business?
With the whole world online now, building a legit webpage has helped us to get on multiple contracts worldwide. We have had the opportunity to send people from different companies our website for them to take a look at us for future business.
How was project management arranged and how effective was it?
Project Management was done through Cal, through many phone conference meetings. Sometimes I would call him for random ideas about our website, and he always made himself available that day.
What did you find most impressive about this company?
Their willingness to go the extra mile. I have talked to a lot of Web Design people before coming across Cal, at Raven Digital. He was the first person that didn't seem like this was just another website for him to build. He took time to get to know my company's In's & out's in order for me to see and reap the benefits of his work.
He was always looking at the bigger picture. He would say yes we need to kill the landing page, but this is just the beginning. He is confident in what he does and eager for you to see the reward.
Are there any areas for improvement?
No areas for improvement, off the top of my head. If I ever had a concern about a certain detail on the webpage, it was handled within a matter of days.

Web Dev & Design for Personality Test Company
"CDHART LLC delivers solutions, not excuses."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
We offer a personality test to the consumer market - from individuals seeking greater insight into themselves, to counselors and therapists who use the test to help guide treatment, to HR types who use the test to identify fit with employment opportunities and job applicants. Our test has been available with an accompanying book since the mid-1990s. I am a partner at NPSP25, LLC.
For what projects/services did your company hire CDHART LLC?
We did not want to write and publish a revised edition of our book and personality test. We wanted to make the personality test available to a broader audience and needed a website that allowed dissemination of our concept, made the test available on-demand, and could securely handle e-commerce exchange. Calvin understood our vision, translating our rambling thoughts into an aesthetically pleasing and fully functional website. He continues to be an essential part of our company's growth plan.
What were your goals for this project?
We needed a website that was easy to navigate across digital platforms and one that could be accessible to a global market. Cal helped us accomplish those essential goals with version 1.0.
How did you select this vendor?
Cal came highly recommended by a Houston-based marketing firm.
Describe the project and the services they provided in detail.
Cal designed the website, including our logo, from top to bottom. We provided copy, and Cal took care of the rest. This was our preferred approach for much of the project to date, but Cal has always been more than receptive and willing to accommodate any changes we request.
What was the team composition?
We are a small company consisting of three principals. Cal is our IT department.
Can you share any information that demonstrates the impact that this project has had on your business?
We would not have a business without a fully functional website. Cal helped us move from concept to product in a timely manner. If/when there are any issues, he is readily available to help trouble-shoot.
How was project management arranged and how effective was it?
Cal sticks to a tight project timeline, delivering what he says when he says.
What did you find most impressive about this company?
CDHART LLC delivers solutions, not excuses.
Are there any areas for improvement?
Not at the moment, but I'm afraid that a broader audience is going to learn about Cal. Once his book of business grows, I hope that he will be able to sustain the same level of customer service that I've come to expect and appreciate.

Describe the project and the services they provided in detail.
We needed to get a 'Careers' section added to our website and we needed it done very quickly. Cal took our design and made it functional in a matter of hours. He has since provided additional website maintenance services for us to ensure our site stays healthy.
What was the team composition?
The team was just myself and Cal. I worked with a few folks on my end to get the design aspect done, but once it was handed off to Cal, we were able to execute on everything without involving an army.
Can you share any information that demonstrates the impact that this project has had on your business?
The turnaround time and consistently quick communication with Cal was hugely beneficial. It allowed us to get our careers section up and functional in a very short time frame so we were ready for career fairs in time. The impact of the project was significant in that it increased our legitimacy in the eyes of our recruits and eased the process by which new recruits could apply.
How was project management arranged and how effective was it?
The project scope was minimal and timing was the biggest factor, so it was mostly managed over a few phone calls and emails. The communication was on point and very effective.
What did you find most impressive about this company?
The communication and turn-around time were extremely impressive, and the quality of work was right in line as well.
Are there any areas for improvement?

Please describe your company and your position there.
I own a corporate housing company and provide fully furnished apartments to those needing temporary lodging. I also just started a new bath and body company where we make natural soaps and body products.
For what projects/services did your company hire CDHART LLC?
We have hired CDHART for several websites we needed developed over the years and are now currently having our main site freshened up with a whole new design and new features to streamline things. I also hired CDHART to design a website for my new business.
What were your goals for this project?
My goal is to have a fresh new design and a website that helps cut down on the amount of customer support calls we receive for my corporate housing company.
How did you select this vendor?
I found Calvin with CDHart back in 2011 when i first started my company. Calvin was easy to work with and he did a fantastic job. This was my very first website. Since then we have had many websites created including our current project that is a re-design of the original website and a website for a new business venture I just started.
Describe the project in detail.
Along with a new fresh look we wanted our website to be able to give customers all the questions to their answers. We also wanted customers to be able to submit customer support and maintenance request online to help cut out the amount of calls we receive on a daily basis. Our website once finished should cut out the calls we receive as well as streamline the process of handling request in an efficient and accurate process.
What was the team composition?
We work with Calvin the owner of CDHART directly. I like the fact that that the owner is hands on and takes great care of our needs.
Can you share any outcomes from the project that demonstrate progress or success?
The project is on going at this time due to my travel these last few weeks but we hope to have the project completed soon. Once the website is ready it will immediate cut out the daily task of emailing customers arrival instructions and other tedious reminders. We also limit our liability with lost or inaccurate support request as they will be required to be submitted in writing via our website.
How effective was the workflow between your team and theirs?
Working with CDHART LLC has been super easy. Calvin is very responsive to my many emails. Calvin has a wealth of knowledge and ideas that has come in very handy. For example when I told Calvin about the many support calls we get due to customers not following the instructions we took the time to send them, it was Calvin who suggested we create a portal for the customers to log into that will allow them to access the information they need as well as submit request in writing. Amazing!!
What did you find most impressive about this company?
Along with Calvin's extension knowledge and ability to pull a design out of my head and make it come to life, I truly appreciate the attentiveness we get from Calvin. I am always super busy running TWO companies so when I take the time to email Calvin a question I like the fact that he replies in a timely mater.
Are there any areas for improvement?
Honestly I have 0 complaints. I have been working with Calvin for 9 years now and we have had many projects over the years. I am 100% satisfied with Calvin's work and highly recommend him.
