Summary
👤
Senior🎓
Top SchoolOleg Sklyanchuk is a Full Stack Developer with 14 years' experience building production-grade web platforms across startups and large enterprises, currently shaping analytics, cross-org aggregation and SSO at Upflow from Paris. He pairs deep front-end expertise in TypeScript, React and modern UI tooling with pragmatic back-end skills in Node.js, GraphQL and Postgres, and has a track record of improving developer workflows—introducing Gitflow, TypeScript migrations and a gradual strategy for fixing strict null checks. Oleg has boosted test reliability and sped up test suites (from 20 minutes to under a minute) while contributing to the karma-jasmine adapter, showing a strong commitment to quality and automation. Comfortable across the stack, he also builds reusable libraries (OAuth/OpenID client work at Société Générale) and advocates for type-safety and clear, maintainable code. Colleagues appreciate his mix of hands-on delivery and internal knowledge-sharing—he speaks at and organizes engineering meetups. Off the keyboard, he’s the kind of engineer who likes croissants, which is telling for someone based in Paris.
