Web applications
Custom applications built with React, Next.js, or Astro on the front, Node.js or Python on the back. Typed end-to-end, tested, and shipped to production on a real schedule.
COR Tech Solutions is a Kyiv-based software company. We design, build, and run web applications for founders and operating teams — front-end and back-end, one team from discovery through production.
Custom applications built with React, Next.js, or Astro on the front, Node.js or Python on the back. Typed end-to-end, tested, and shipped to production on a real schedule.
REST and GraphQL APIs, third-party integrations, webhooks, and background jobs. We wire systems together so your team does not have to hold them together with glue code.
Admin panels, operations dashboards, and workflow tools that replace spreadsheets and one-off scripts. Built for the people who use them daily, not for a demo.
Inherit a legacy codebase. Upgrade dependencies, fix production bugs, add features, and document what is actually there — so the next team does not start from zero.
We work in short cycles with written scope and weekly updates. One project lead per engagement, direct access to the engineers who write the code, and a habit of saying no to things we cannot deliver well.
