01
Web applications
Custom web applications built with React, Next.js, or Astro on the frontend and Node.js or Python on the backend. End-to-end typed, thoroughly tested, and shipped to production on a real schedule.
Company
COR Tech Solutions - Software that ships.
COR Tech Solutions is a Kyiv-based software engineering company. We design, build, and operate web applications for founders and product teams - frontend and backend, as a single team from discovery through production.
Capabilities
Four things we do well.
02
APIs & integrations
REST and GraphQL APIs, third-party integrations, webhooks, and background jobs. We connect systems properly so your team does not have to hold them together with glue code.
03
Internal tools
Admin panels, operational dashboards, and workflow tools that replace spreadsheets and one-off scripts. Built for the people who use them every day, not for a demo.
04
Maintenance & modernization
We take over existing codebases. Upgrade dependencies, fix production issues, add features, and document what is actually there - so the next team does not start from scratch.
Approach
Small team. Clear scope. Shipped work.
We work in short cycles with a clearly defined written scope and weekly updates. Each engagement has a single project lead, direct access to the engineers writing the code, and a strict habit of saying no to work we cannot deliver well.
