We start by understanding the business behind the software, then design and build the product with one in-house team. There is no handoff to a separate group and no work passed offshore. The people who plan your project are the people who write the code, ship it, and answer for it.
We partner with growing businesses to build software that is reliable, maintainable, and built to last well beyond launch.

What you get when you work with Devsynth:
In-House Team
Your project is built by Devsynth engineers, not contractors and not an offshore vendor. One team owns the architecture, the code, and the delivery, so the quality stays consistent from start to finish.
Full Project Ownership
We take complete ownership of the build, or work alongside your existing project manager when you already have one. Either way, you get clear accountability and a single point of responsibility.
Cross-Platform Engineering
We build once and ship everywhere. Our work on EVDC put a single codebase across web, iOS, and Android at the same time, which kept the product consistent and the cost in check.
Support After Launch
Shipping is the start, not the finish. We stay with you to maintain, improve, and scale the product as your business grows.

Devsynth is a US-based custom software development company headquartered in St. Petersburg, Florida. We design, build, and support custom web, mobile, cloud, and AI products with our own in-house team.

No. Devsynth is a project-based, in-house company. We do not outsource your work offshore and we do not drop individual contractors onto your payroll. Your project is built and owned by the Devsynth team.

We work in three phases: discovery and planning, design and build, then launch and support. We start by understanding the business problem, plan the scope together, build in clear stages with regular check-ins, and stay involved to maintain and improve the product after it goes live.

 You work directly with our in-house engineers and project leads. The same team that plans your product writes the code and ships it, which keeps quality and accountability in one place.

Yes. We can take full ownership of a project with our own team, or work collaboratively alongside your project manager when you already have one leading the work. We adapt to how your business is set up.

 We build custom web platforms, mobile apps for iOS and Android, cloud infrastructure, and AI-driven features. Our EVDC project is one example: a cross-platform EV charging product built on a single codebase serving web, iOS, and Android at once.
