Oleksandr Romanov

Senior front-end engineer based in Lisbon, 8+ years building Angular apps — most of it on large-scale, high-load platforms where the frontend has to stay fast and maintainable under real traffic. Current across Angular v7–21: standalone components, Signals, zoneless, the new control flow, @defer, RxJS-driven state, NgRx. Recent work has been closer to tech-lead than pure IC — owning frontend architecture, setting component and coding standards, and making the calls on tooling and patterns. Angular's my main stack, but I'm solid with React / Next.js as well.

Spent the last three-plus years at Mythical Games as a core front-end engineer (team of 3) on the platform behind NFL Rivals and FIFA Rivals. The work I'm proudest of there: a full performance refactor of the auth/account module (migrated to standalone architecture, cut bundle size, added build-analysis tooling); a custom state-driven filtering system built from scratch with RxJS, with the REST contracts defined together with the backend; and a multi-provider transaction integration with real-time authorization flows. Later co-led a rebuild of core functionality onto React / Next.js. Before that, three years at DMarket on a high-traffic marketplace, plus an internal operations platform I designed and built end-to-end.

On the side, I've built and run a full-stack digital asset trading platform solo — Node.js/Express backend, custom frontend, everything from API design to trading logic to the UI — bootstrapped from a couple hundred dollars to around $25k with no outside capital. Also co-inventor on a filed patent application for transferring digital assets across systems.

Studied software engineering at Kyiv Polytechnic (Master's and Bachelor's). Outside work: CS2 content creation and streaming, numismatics, and sports history.

Looking for senior Angular roles — remote for an international team, or hybrid here in Portugal. Keen to bring the high-load and marketplace experience into enterprise SaaS, fintech, or healthtech.
