Web Development for Software Solutions Provider
"I would say that becoming a partner with SotaTek is the wisest decision we ever made."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
NewWave Solution is a software solutions provider as well as a software outsourcing company. I am the CTO of NWS and had an amazing experience working with SOTATEK team.
For what projects/services did your company hire SOTATEK JSC, and what were your goals?
Web Development for Organizational Benefits
We needed to reduce the effort made by our internal team inhouse as our managament and productivity needs to be improved to be more efficient. Since we do not have in house developers we found SOTATEK and partnered with them in the project to develop a web-based app to manage, thus increase innovation and productivity.
How did you select this vendor and what were the deciding factors?
We searched online then shortlisted top companies in Web Development & Custom Software Development. We found positive reviews from past customers of SOTATEK then decided to talk with their representatives. Totally satisfied with their customer service from the very first interaction.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
SOTATEK developed a management solution for us. Initially, we came to them with a prototype that we’d implemented in a few places, talking them through what we’d done and what we wanted to do. That included some code that we’d developed, screenshots of our rudimentary platform, and customer research. SOTATEK then guided us through their design phase. We went through user personas in much greater detail, and created wireframes. Once we transitioned into full-scale development, they built a cloud-based app in AWS and released.
How many people from the vendor's team worked with you, and what were their positions?
We worked initially with the sales person, and subsequently with SOTATEK's Sales Director, then Project manager, Head of Technical team and developers. The CEO and some other top managers were also involved in some communications to clarify our requirements and needs.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
Our company inclusing all departments used to validate the work are satisfied with final result. Successfully had a system to track and increase performance our own.
Describe their project management style, including communication tools and timeliness.
We used Jira to track all tasks, timelines, and deliverables. The PM we had kept everything on track, and challenged the team to get key components done when we ran into some challenges.
What did you find most impressive or unique about this company?
I would say that becoming a partner with SotaTek is the wisest decision we ever made. They are 100% customer-oriented. In the course of the project, SOTATEK team offer us experts experienced in specific industries, focusing on IT Consulting and Strategy to help us solve the challenges. I really appreciated their customer-centric strategies and dedicated efforts.
Are there any areas for improvement or something they could have done differently?
In general, I had no big problems with the dev team or managers from SOTATEK.

Please describe your company and your position there.
We at Ekoios help Startups and Enterprises harness the power of AI and Blockchain by universalizing high-tech products and bring them into real business application, especially in finance industry. I am the Product Line Director of Ekoios, who directly worked with SOTATEK in various projects and got to know their founders for a long time.
For what projects/services did your company hire SOTATEK JSC, and what were your goals?
Consulting & Blockchain App Development SOTATEK helped us to achieve our goal in blockchain app creation. The main objective was to design and develop a web and app with customized features which thus increase user experiences and support for our services promotion. The main features include tracking for trading, volumns, tokens, reserves, trade history, defi, updates, etc.
As our current issue was online interaction and low number of users, we need our online presence unique and had to reach the right target market. That was our challenge and SOTATEK helped us to solve it by developing outstanding websites and apps that converted to many organic leads and users afterwards.
How did you select SOTATEK JSC and what were the deciding factors?
I got to know Tyler and William from college before they created SOTATEK. Since then, I have worked with SOTATEK a few times and the experience overall was always beyond expectation. Reason for choosing them is they have great quality for any project, highly reliable, have the ability to update new technologies, always on time and offer reasonable cost.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
SOTATEK built a customized web/app named Kyber Network Tracker which helped our user to track, store the documentation data in Blockchains, showing realtime info of trading, rate, sources, reservations, search history, etc. Their team really put an effort to try to walk in our shoes and get a proper perspective on our needs. The process went effectively and efficiently.
SOTATEK team designed the ledger for us to confirm and agree on the features and integration details. The development process was smooth. We ran into a couple of challenging parts during the integration process, but the team quickly addressed it.
All along the project was continuous and open communication between the 2 parties that all the issues were approached and solved. The project was delivered on time and budget.
How many people from the vendor's team worked with you, and what were their positions?
We directly worked with a project manager. Mainly, we communicated with the project manager and the developers. Their team often consisted of 1 project manager, 1 designer, 2 developers, 1 QA. I also worked with SOTATEK's founders and managers for additional Blockchain features and IT consultancy about strategic parts.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
This dedicated team of professional engineers proved to develop the platforms in both blockchains and building scalable technical solutions. The timeline was six months, and that wasn’t as short as weeks. However, the amount of work that went into that site and the amount of customization and features that we added were very aggressive for that timeline.
They did a really good job and high-quality work, and they were reliable. The number of users increased 150% comparing with our previous app.
Describe their project management style, including communication tools and timelines.
We had daily/weekly meetings and communicated mostly through direct meetings, Google Meets and share documents on a daily basis.
What did you find most impressive or unique about this company?
When working with SOTATEK, timing and efficiency were never my concerns as they were always ahead of the schedules with all the tasks. Any requested change from our team was quickly adopted, which I highly appreciated as a client.
They are very customer-oriented, always stand by their promises and feel really comfortable with new technologies/ changes. Hence, SOTATEK has become our trusted agency for many later IT projects.
Are there any areas for improvement or something they could have done differently?
So far everything has gone quite well. There are no areas that I can think of for SOTATEK needs to improve on.

Please describe your company and your position there.
Metrixa is an Australian digital marketing company offering services in Bid Management with proven strategies that can help increase clients' ROI. I am the Digital Marketing Team Leader of the company, who hired SotaTek for an internal software for tracking metrics and analytics.
For what projects/services did your company hire SotaTek, and what were your goals?
We required from SotaTek the Software Development and IT Consultancy services. The goal is to develop a software from scratch within a strict deadline in 4 months.
Since we from the marketing side have limited knowledge about IT and its trends, SotaTek team gave us completed and continuous consultancy to give the most suitable solutions for our internal analytics challenges at that moment.
All of their ideas were based on our vision, which is highly appreciated.
How did you select SotaTek and what were the deciding factors?
We had a reference from a colleague who successfully implemented other IT project in 2018 with SotaTek. I also chose them among 7 shortlisted vendors based on their proven track record in the field and testimonies from other companies and partners.
Both parties have further discussion and SotaTek turned out to have everything we needed, with a full team of IT experts with skills and experiences. We could start our working procedure within nearly 1 week of discussion.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
The idea was to give a possibility for internal users (our staffs) to track marketing analytics metrics and performance in company website and various social channels, including Google, Youtube, Twitter, Linkedin, keywords trackers.
The software also allow us to create profiles, make in-app records and many other analytics features and tools which was extremely helpful for our workflow and performance.
How many people from the vendor's team worked with you, and what were their positions?
SotaTek provided us a team of 5 members, including PM, devs, QA. Their experts and founders also give us consultancy and feedbacks along the project.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The result was overexpected that first we only used the software internally, then started to use it for our clients that users would no longer have to use various marketing analytics tools and platforms.
Only 1 software can combine all. All of us also complimented the usability as well as the look and feel of it. It is user-friendly and convenient to use in the long term.
Describe their project management style, including communication tools and timelines.
SotaTek did a great job in daily conversations, report, follow up and support us even after the project was done after half a year. We had Skype calls with project manager 2 times a week. Also, I had meetings with SotaTek founders about strategic tasks one time per month.
What did you find most impressive or unique about this company?
A timely partner, SotaTek always worked in the fastest pace, met deadlines and encouraged direct communication with all team so that we can catch up daily. Reliable.
Because we didn't have an extensive technical background or access to IT specialists, we were glad to find a reliable partner like SotaTek that would have the expertise in the development of software and provide full-cycle development, which would include strategic consulting and custom development.
Are there any areas for improvement or something they could have done differently?
I asked them to provide more general documents to guide us since we were not familiar with IT/tech terms. In this field, they improved immediately.
