Rockstar🎓
Top SchoolAndrii Los is a seasoned software leader and entrepreneur with 10 years of experience building high-performance web platforms and developer tooling, now CEO and Co‑Founder of Genery based in Krakow. He has led engineering and founding roles at Perplexity, Revolut, and multiple startups, delivering large build and runtime performance wins (e.g., 90% render reduction, CI/build times cut by orders of magnitude) and introducing observability, monorepo strategies, and robust DX practices. Hands-on across frontend and backend, he’s implemented migrations to Bazel, Turborepo/PNPM, GraphQL type-safety, and ESM-native builds while also shipping UI kits, Storybook setups, and Playwright e2e pipelines. An active open-source contributor, he maintains a popular React EasyMDE wrapper where he modernized SSR support and migrated to hooks and EasyMDE for long-term maintainability. Beyond engineering, he blends product instincts with operational rigor—coaching teams, hiring QA automation, and turning performance bottlenecks into repeatable processes. Outside work he’s unusually balanced: a former tenor and avid singer who also competes in padel and follows F1.
