Mykyta Vasyliev

Full-stack Engineer building platforms and guardrailed AI pipelines end to end.
UkraineWhat I'm looking for
I’m a full-stack engineer with 9 years building and owning production web applications in React, TypeScript, and Node.js. For 5.5 years I’ve been a core engineer on a live-ops A/B experimentation and remote-config platform used by mobile-game teams to run experiments and roll out features across a portfolio reaching millions of players.
Recently, I designed and built, solo and end-to-end, an AI-driven production pipeline for playable ads—using generative image models for assets, an LLM as the code-implementation engine, automated browser QA, and a 12-point compliance verifier that gates every build before it ships. I’m strong on what makes AI products real: verification, guardrails, reproducibility, and keeping a human in control of the loop, backed by careful TypeScript, tests, and CI-style quality gates.
