What Clients Think About Us
"The Tweerous team has developed the core frontend and backend of the RISE Crypto Trading platform, a highly complex task that they mastered exceptionally well.
A huge advantage of this team is that they are very much autonomous and donât require micro-managed project management. True self-starters.
RISE was a very complex FinTech product that usually requires double their team size but Tweerous managed to deliver a high-performant product with very little maintenance requirements on time and budget."
"I have worked with the Tweerous team on the UpTick mobile investment and trading platform for many years and can highly recommend their services.
They deliver Triple-A products with clean code and have been a true CTO-level partner rather than only an outstaffed team.
Their level of expertise when it comes to both frontend and backend is exceptional and you can be lucky to work with them if you have the chance."
"We engaged Tweerous to solve a tricky legacy-code technical-debt problem with iOS and Cordova plugins.
They proved themselves to be extensively knowledgeable and very easy to work with. They provided a clear-eyed assessment of the issue in a very short time, and unusually for the software world, an accurate effort estimate to resolve the problem.
Moreover, they were helpful and generous with their time in educating us about the quirks and insider tips of the Apple Xcode build process.
I am looking forward to working with Tweerous again in the near future!â
"I had the pleasure of being the Software Development / Delivery Manager supervising the Tweerous team working with a larger joint development team for MentorMate and DTN.
I was impressed early on with the way they began to engage and fully understand the needs of the project, which was well underway when they joined the effort. They pushed hard to accomplish the objectives in short order. They also jumped in looking for how to best implement the strategies presented during the course of the agile sprints in which they worked.
The Tweerous team clearly demonstrates in their work ethic, and in their openness to discuss the work, that they do indeed care about the results of the project and product being created. Although they did not work for DTN directly, you would not know this by the passion they showed. They take ownership of what they are doing and clearly want to produce the best work product they possibly can.
Tweerousâ iOS developers are very talented and are both current on the technology and eager to remain so. They actively present best practices and professionally push team members to continue to improve. They have a keen ability to articulate data about difficult concepts and have a passion to deliver value-added work product.
I believe Tweerousâ experts would make a great addition to any team and specifically in a technical lead role where they can present the best practices and guide others as they create amazing products."
"Having worked with Tweerous on multiple successful projects, I confidently engaged them to develop CryptoAlerts, a subscription-based platform for cryptocurrency market analytics.
The team delivered exceptional value from day one. They engineered a robust cloud-based solution and launched it within our planned budget. Their cost-efficient integration with a global cryptocurrency data provider was particularly impressiveâthey structured the solution to operate effectively within the SLA limitations, ensuring consistent service quality without driving up operational costs.
What impressed me most was the platform's reliabilityâit operated virtually maintenance-free throughout its entire lifecycle, a testament to the quality of their cloud architecture and development practices. This allowed us to focus on growth rather than firefighting technical issues.
Beyond the technical execution, Tweerous has been a true strategic partner, providing expert consultancy and responsive support whenever needed. I wouldn't hesitate to work with them again on future projects."
"I had the pleasure of working with Tweerous on a variety of complex projects, including ticketing systems, mobile apps, database management, new platform design, and an e-commerce website. From start to finish, my experience was nothing short of excellent. The team demonstrated exceptional technical expertise, sharing valuable insights and delivering high-quality solutions. They were always responsive to our needs and went above and beyond to ensure that each project component integrated seamlessly with our existing systems.
Their ability to translate our ideas into intuitive, functional designs, coupled with their proactive communication, made working with them a smooth and collaborative process. Not only did they provide innovative solutions, but they also offered valuable insights and recommendations that significantly improved the overall product.
If youâre looking for a skilled, reliable, and forward-thinking development team, I highly recommend Tweerous. They are true professionals who are dedicated to delivering exceptional results."
About Us
Built by Engineers, Shaped by Experience
Tweerous was founded by three university friendsâJimmy Ostoich, Evtim Papushev, and Kiril Nozharovâwho have known each other since their student days and began their professional careers as software developers in 2006-2007.
After working independently for leading companies such as Telerik, Vayant Travel Technologies, Mentormate and CommEq Asset Management, they reunited in 2012 to establish Tweerousâcombining their individual expertise and shared values into a first-rate engineering partner built on trust, technical excellence, and long-term collaboration.
Our Philosophy
Founder-Led Engineering
Every project we take on is personally overseen by our senior teamâno managerial layers, no dilution of responsibility.
Perfect Technology Fit
We select technologies based on the problem, not the trend. Whether it's Swift, Rust, Vue.js, React.js, PostgreSQL or distributed microservices, we engineer each layer for efficiency, security, and clarity.
Quality Over Volume
We deliberately remain smallâtaking on fewer projects, but giving each one full focus. Our clients stay with us for years because we treat their systems as our own.
Let's Build Something Exceptional
Your vision deserves a partner who treats it as their own. Whether you're building something new or modernizing the systems you already rely on, we're ready to help.
What Happens Next
Once we hear from you, one of our principals will reach out personally. You'll speak directly with the engineers who'll be designing and delivering your solution.
