What I'm looking for

Senior/Lead Frontend role with a focus on building scalable, high-quality web applications. Interested in product-driven teams, ownership, and technical leadership. Prefer remote-first companies, modern stack (React, TypeScript), and opportunities to impact architecture and mentoring.

I’m a Senior Front-end Engineer building complex multi-tenant SaaS products with TypeScript and React/Vue 3, backed by Node.js and modern APIs (REST/GraphQL). I care about architecture, performance, UI quality (design systems, reusable components, accessibility), and predictable data flows—so I can own features end-to-end from UX details to API integration, testing, and CI/CD delivery.

In my current role, I built and owned core enterprise B2B inspection features, including an offline-first PWA with voice-driven audits and real-time sync, plus data-heavy interfaces handling 100k+ inspections. I strengthen quality and DX with Vitest + RTL (up to 90% coverage), Storybook, and migrations like Webpack → Vite, while integrating AWS/Azure serverless workflows and observability (Mixpanel, Coralogix, Groundcover). I also adopted Next.js across CSR/SSR/SSG/ISR/PPR and improve feature delivery speed with spec-driven, AI-assisted development.
