About
We build. We secure. We maintain.
KYC Code Systems is a software development company based and founded in Kyiv, Ukraine. We build secure web applications for teams that value quality, reliability, and long-term maintainability. FinTech, SaaS and internal enterprise tools are common for us, and we are comfortable in any domain where security and code quality matter.
How we started
KYC Code Systems was founded in 2026 by a group of senior engineers who previously built and operated web products at large international FinTech companies. Across the team we bring more than a decade of hands-on experience shipping, scaling, and maintaining real-world software.
We started the company because we wanted to focus on the kind of work we enjoy and do best: building secure, well-engineered web applications for clients who value quality over shortcuts. Each of us has spent years in environments where code is reviewed, tests matter, and decisions need to be justified. That is how we work here too.
What we do
We develop full-cycle web applications and/or modules for existing systems. Software development from scratch, back-end and API, integration and support of existing code are our day-by-day work.
Security is part of how we work, not an afterthought. Authentication, encryption, least-privilege access principle, audit and secure PII handling are standard practice in everything we ship. Most of the clients we work with cannot afford for these to be retrofitted later, and we engineer accordingly.
KYC, identity verification and AML integrations are one of our specialties. We work with identity verification providers, integrating them into real workflows of operation and coliance commands.
How we work
We work with clients in whichever engagement model fits the project. Hourly billing for ongoing work and research. Fixed-price with a written scope for well-defined deliverables.
Communication is straightforward. We default to weekly written status updates, with calls when something needs deciding.
Our Team
Our team are senior engineers with years of production experience. We pick technology based on what the project actually needs, not on preference.

- Frontend

When a project requires something outside of our usual toolkit, we pick it based on what the project actually needs. The fundamentals of good architecture are the same for any language.
