Lukas Kouril

Senior Frontend Engineer

I specialize in TypeScript and React, from micro-frontends for online banking to AI tooling in production teams. I care about readable code and frontends that still make sense a year later.

Computer Software Engineering

Intensive software engineering academy in Barcelona focused on full-stack web development. I worked mainly with JavaScript, TypeScript, React, Next.js, Vue.js, Node.js, Express.js, PostgreSQL, Prisma, and MongoDB, alongside data structures, algorithms, and tools like Git, Docker, Vercel, and Figma. Most of the learning came from building actual projects, which is also where I got hooked on software engineering.
