Profile
Full-stack engineer with 16+ years owning web products end to end—React/TypeScript UIs and accessible component systems, Node.js and Ruby on Rails services, AWS delivery, and org-wide architecture. Comfortable across the stack and across the lifecycle: requirements, design, implementation, deployment, and operation. I drive modernization, partner closely with product and design, and ship sustainable practices—migrations, monorepos, observability—that compound team velocity.
Experience
Senior Frontend Developer
Apollo.io · Warsaw, Poland
- Tech lead for the monorepo foundation—migrated design system (v1 + v2) and shared hooks/utilities into the new structure, and established the package-isolation paved path (shared ESLint config, TypeScript patterns) ready for product-team adoption.
- Led the internationalization initiative end to end—built the translation tooling and CI/CD pipelines, and shipped Portuguese as the MVP locale.
- Built a performance notification tool that alerts on regression spikes across the org.
- Drove the react-router v3 → v6 migration—introduced proxy components to bridge legacy patterns with v6, then rewrote consumers to use the new hook-based APIs.
- Built a meetings notes feature on TipTap (Notion-style rich-text editing) replacing a plain-text predecessor—including the DB migration of ~few million existing notes into the new format.,
Frontend Lead
INDY · Warsaw, Poland
- Owned the full frontend at INDY—responsive SPA web app, landing pages, and admin tool—across an engineering org of ~20.
- Shipped an in-app chat with direct/group messaging and email integration (replies thread back into chat)—React UI, real-time delivery, Node.js services.
- Built end-to-end invoicing and payments—custom templating engine, single/bulk PDF rendering pipelines, and payment integrations across Stripe, Plaid, and PayPal.
- Built a files-drive feature with sharing, permissions, and in-browser previews across images (JPEG/PNG/SVG), PDF, video (MOV/MP4/WebM), and audio.
- Built an in-house calendar with event management and bidirectional Google Calendar sync.
- Built the landing pages on Next.js (SEO-optimized, Lighthouse >90) with a Strapi admin enabling self-service content updates by SEO specialists across landings and blog.
