We hired SotaTek to build a launchpad for IDO to support owners of Web3/ Metaverse applications. After extensively searching for experienced Software Providers and asking referrals, we decided to partner with SotaTek - Top Vietnam Blockchain Company. We had to admit that SotaTek had finished the project much better than our expectations. The project expected to finish in 5 months but they delivered us just after 4 months, which helped our platform to go live on the pre-scheduled date with full functionality. Besides, throughout the development phases, despite some difficulties, they still can handle very well. A great impression left on me! Highly recommended to hire them.

"We need a Mobile Wallet in mobile application for data virtual app that stores payment card, transaction, spending history and data information on a mobile device. It is expected to be a convenient way for users on a daily basis and solve their problem in transactions issues. SotaTek appeared as our partner in Mobile App, App Design and IT Consultancy who helped us to rebrainstorm, rethink and redesign the interface. Their team took a creative approach to the UX redesign with custom illustrations and customer-oriented mindset. The consultant team suggested us to add a new personal finance management module, social media money transfers, bill payments and credit service which was extremely satisfied our client and was helpful after publishing the app. "

SOTATEK helped us to achieve our goal in blockchain app creation, 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. 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 Innovative, Creative, Reliable and Very Open-Minded as their team always stand by the promises and feel really comfortable with new technologies/ changes.

App Designing (UI/UX)Software Development

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. 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. 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 very convenient to use in the long term.

I have been working with Sotatek for about a year now and I am impressed by their commitment to provide the best service. To be more specific, I have been working on several projects with them, and there were times when we have to change our requirements due to unavoidable circumstances. Despite of that, they were able to handle our requests flexibly. They always deliver the product on time, and the quality is excellent too. They have a strong group of engineers with a diverse range of expertise, so when I have a request for a development project with a specific technology, they are able to accommodate our requests without any difficulty. In terms of communication, many of their engineers are fluent in English, so I could interact with the engineers directly, and most of them are very responsive. They are also open to share their experience and work, and it helped to establish trust in our partnership.

I've been working with SotaTek for years now, and I've always been super impressed by their communication, skills, and organization. Even with them being in a different timezone from us, it feels like they're always online and ready to answer any questions that our local team has. With this level of talent available, it's no wonder why they've been able to scale their operations massively over the past couple of years. Sotatek's scaling also allows us to scale when we need extra developers assigned to our project. I've also had code audits from other companies CTO's to check the quality of our codebase, and the auditors have always struggled to find anything negative to say, it's always positive. Highly recommended. Thank you all for the hard work, looking forward to continuing to work together for years and years to come.

After the first time partnered with Sota Tek, which was totally beyond my expectations and generated great results, Sota Tek has become our trusted agency for many later IT projects. This dedicated team of professional engineers has proved to have in-depth experiences in both blockchains and building scalable technical solutions. When working with Sota Tek, timing and efficiency were never my concerns as they were always ahead of the schedules with all the tasks.
