RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

There have been four Sprints so far. We are discussuing the Sprint backlog items for Sprint 5. The completed tasks are too numerous to list here, but to give you an idea of the extent of completed work, Sprint 1, included:

1. UI/UX Enhancements

3. Changes to metric displays
4. Configuring data storage,
5. Backend & Performance Opimization
6. CloudFront Intergration

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Perfsys delivered all the work on time. The team addressed every issue I raised with speed and dedication.

What was your primary form of communication with Perfsys?

• Virtual Meeting
• Email or Messaging App

What did you find most impressive or unique about this company?

First and foremost, what was most impressive about Perfsys was the team's domain expertise. AWS cloud software is complex. Generalist full-stack developers couldn't get the job done. Perfsys did.

Our perspectives aligned on developing a product for a global marketplace. Our streaming music service features songs from 40 countries on 6 continents. We liked that Perfsys could bring international cultural perspectives to KaZang's development.

Are there any areas for improvement or something Perfsys could have done differently?

No  issues. They call themselves Perfsys. We call them the “Dream Team.” If you know the NBA and Olympic basketball, you’ll know that’s high praise. The Perfsys team fixed all AWS analytics issues for our early-stage music app, KaZang. They resolved a bug that froze our metrics on a specific date, Then, they restored KaZang's data flow across four AWS services (i.e., Pinpoint, Cognito, Amplify, and Athena).

Over a period of six months, three different sets of full-stack developers failed to integrate AWS cloud analytics with our platform. Perfsys succeeded. If you have a tough job you need done to the highest standards, do yourselves a favor and hire Perfsys. On a scale of five stars, we give them a six!

6-10 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

Develop a web-based system for managing content for digital signage and communicating with and updating media players, including fetching and processing data from external sources. 
Overview Structure: The system should be capable of hosting multiple clients in separate instances, with several users per client. A client can upload materials such as videos and images and link them to specific dates and media players. Some content will be fetched from external databases. 

1. Media Players: The administrator creates media players and integrates them with the system. The task involves building an API solution based on the requirements of the media players. The media players will continuously query the server for available settings, playlists, and video clips. 
2. Material Management: Develop a solution where clients can upload materials in the form of images and videos and create sequences with these files in the browser. On the server side, the sequences will be transposed into video clips in a specific format. 
3. Material Storage: Implement features for uploading and storing materials that clients can retrieve to create material as described in point 2. 
4. Content Planning and Scheduling: Build functionality for adding materials and publishing settings. It should be possible to create different playlists, group content, and sort content locally for each media player and globally for multiple media players. 
5. Retrieval of Data from External Databases: Retrieve video materials, publishing settings, and information on where the content should be displayed from clients' booking systems. Automate the process of creating and publishing incoming content. 
6. Data Retrieval for Scheduling: Based on clients' schedules, retrieve data and automatically publish content according to the schedule. For example, "Show ad X when ferry Y departs from port M."

After a couple of initial calls, we selected to work with Perfsys based on their approachability and domain experience.

Describe the project in detail.

Once we selected Perfsys, they were eager to engage and deep-dive on our needs as a startup.

Our main interactions were through a single point of contact, though there were named contributions from another developer.

The project was completed easily within the expected time-frame, allowing our internal engineering resources to focus on core business decisions while the cloud deployment was taken care of by Perfsys.

How effective was the workflow between your team and theirs?

The workflow was tightly integrated with how we like to operate. Everything was communicated through Slack, with regular updates. Code commits, and build status updates set up to automatically notify the engineering team of progress.

We hired Perfsys to develop a complex Extract Transform and Load project

What were your goals for this project?

Our goal was to be able to dynamically assign descriptions, labels and categories to people places and things.

SOLUTION

How did you select this vendor?

Perfsys came highly recommended by an existing client.

Describe the project and the services they provided in detail.

Perfsys built a serverless architecture system that allows us to quickly and cost-effectively search terabytes of data, find the relevant record, extract the relevant values from the record and append the information to our database. They also built a front end user permissioning system.

What was the team composition?

The team consisted of two dedicated developers and the company's principal who provided hands-on strategic direction.

There is very little I would recommend as areas for improvement.

BACKGROUND

Please describe your company and your position there.

I am the CTO of Intro, Inc.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Perfsys?

We hired Perfsys to create a serverless website and a CodePipeline for building and deploying sources. 

What were your goals for this project?

 The goal was a cloud-based website that met our requirements. 

SOLUTION

How did you select this vendor?

We selected them based on recommendations from our partners.

Describe the project in detail.

They built the website using AWS S3 and AWS CloudFront. The project also required experience in Python, API Gateway, and AWS Lambda. 

What was the team composition?

They provided one full-time Python developer, one full-time Javascript frontend developer, and one development operations manager. 

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

I trust them. I can go to bed at night and know that I will not wake up in the morning to a user complaint about website or login errors, something I experienced on a weekly basis with my previous agency. I have a very high level of confidence with Perfsys. Their maintenance package includes built-in alerts, none of which have been triggered yet. If something were to go wrong on the Perfsys side, I am confident they will know about it and resolve it before I hear of it from a user. 

How effective was the workflow between your team and theirs?

Their development workflow was based on the Agile/SCRUM approach. We had daily sync calls as well as weekly planning meetings.

What did you find most impressive about this company?

Although we may suggest an idea, they will always keep us straight on industry best practices. The maintenance package I pay now is less than the retainer I for the previous agency, who regularly complained that the retainer was not enough to cover the number of hours they worked each month.  

Are there any areas for improvement?

They need to be more proactive in creating bespoke elements on the website and in suggesting better enhancements.

BACKGROUND

What were your goals for this project?

We wanted to develop a scalable and configurable product that could be deployed to a customer site or hosted in our datacenter.

SOLUTION

How did you select this vendor?

We used an internal rating process in which we choose three vendors and have a formula with which we weigh their strengths and weaknesses. We do this in numerous ways, but mainly through interviews and open-source research.

Can you go into detail about the services they provided and the scope of the project?

Perfsys provided full-stack development using technologies such as Node.js, Docker, NoSQL, Hadoop, and Ext JS.

What was the team composition?

The team scaled from three to five people depending on the amount of work for a specific time frame. They also provided development and architecture support.

Are there any areas where they can improve?

None that I can remember.
