What I'm looking for

I’m looking for hands-on Senior or Lead Full-Stack / Frontend-heavy roles, including full-stack AI engineering on products with LLM-based features, with remote teams in Europe—at product companies, SaaS businesses, startups, or consultancies. I’m available full-time or as a B2B contractor.

At Freightlogs, I build across the shipment lifecycle, from a Node.js/Express BFF between the Next.js/React frontend and backend services to collaborative eCMR workflows with undo/redo and conflict handling. I lead a team of three developers and own technical decisions across frontend and backend.

I built a document digitization pipeline using the Claude API to extract structured fields directly from scanned documents. Zod validation, automatic retries, and operator review help make the extracted data usable in shipment records and eCMR workflows.

At BuildIT, I led the migration of a construction SaaS platform from Vaadin to React, Next.js, TypeScript, and GraphQL/Apollo; calculation generation dropped from 20 seconds to 5. I also rewrote five legacy modules, launched two new modules, and shipped a React Native app for iOS and Android.

At Anwendo, I reduced render time in a high-volume mailbox app by 60% with virtualized lists and memoized selectors. I’m looking for hands-on Senior or Lead Full-Stack or frontend-heavy roles, including full-stack AI engineering, with remote teams in Europe.
