About
I’m a senior front-end/product engineering engineer with 15+ years of experience building large-scale product platforms, design systems, and front-end infrastructure across FinTech, Web3, AI, and SaaS. I focus on strong technical ownership and product mindset—turning technical planning into shippable, user-facing features with a high level of polish.
I’ve led front-end initiatives across multi-team engineering orgs, shipped Next.js and React-based products used by millions of users, and integrated LLMs into developer and product workflows (including AI-assisted tooling and internal automation). I’m equally comfortable working fully remote or hybrid in the EU, thrive in async collaboration, and enjoy partnering with design, product, and platform teams where UI craft and product ownership both matter.
