A company, not an agency.

We build custom web applications, APIs, and internal tools for clients in Ukraine and abroad. Typical projects are a founding team that needs an MVP shipped, an operating team that needs an internal dashboard to replace a growing pile of spreadsheets, or an existing product that needs a new integration or a modernisation pass.

Our default stack is TypeScript on both sides — React, Next.js, or Astro on the front, and Node.js on the back, with PostgreSQL for storage. When a project genuinely needs something else, we pick it on merit and say so up front.

COR Tech Solutions is a software development company. We are not a marketing agency, a body shop, or a generalist consultancy. We write and ship code, we document what we ship, and we stay around long enough for the team that inherits the code to get comfortable with it.
