What I'm looking for

I’m looking for a team where I can own end-to-end delivery, build high-performance data UX (React/Vue + real-time), and responsibly ship AI-powered features. I want strong engineering standards, security-minded culture, and measurable impact on users.

I’m a Senior Software Engineer and Lead who builds “data-rich, high-performance” interfaces that make complex information feel effortless. I bring a product engineer mindset, focusing on performance, reliability, and UI clarity under massive real-time data load.

Most recently, I had “full ownership of the frontend team and product end-to-end” on a developer-facing platform. I shipped a new cloud platform using Next.js, TanStack Query, EffectJS, ReactForms, and Recharts—improving performance, consistency, and overall UX—and supported “SOC 2 Type II compliance” via bi-weekly security audits.

At Flightradar24, I developed and maintained software used by “over 6 million daily users,” leading high-impact migrations to Vue 3 (Composition API), Pinia, and Vue Router. I also led a “migration from raster to vector-based maps using WebGL,” delivering a full visualization and performance overhaul at scale.

I’ve also built real-time B2B and Web3 experiences, including SvelteKit interfaces with WebSocket streams and reactive state, plus micro-frontends and multi-tenancy. Across roles, I integrate agentic AI workflows (Cursor and Claude), improve delivery standards, and use modern tooling and monitoring to keep teams shipping confidently.
