About
I’m a senior frontend developer with around eight years of commercial experience building production-ready web applications and websites for enterprise media, healthcare, and B2B clients. I’m strong in JavaScript and TypeScript and I work fluently across React, Next.js, Angular, Svelte, and SolidJS, applying engineering practices like TDD/SBDD, SSR/SSG, and performance optimization (including Core Web Vitals) to deliver reliable, user-facing features.
I also have solid backend capability with Node.js, NestJS, Express, PostgreSQL, Redis, Docker, and Golang, and I’ve worked in SPA and micro-frontend setups using Module Federation, WebSockets, REST, GraphQL, and real-time integrations. I enjoy turning product requirements and translated specifications into maintainable code, collaborating across teams of different sizes, and supporting end-to-end releases—whether that’s media workflow platforms, B2B landing pages with HubSpot/SEO tracking, or full-stack products delivered as an independent contractor.
