Full-Stack Developer (React, Node.js, MongoDB, AI integrations)

Full-stack developer based in Finland, working in JavaScript, React and Node.js with MongoDB. I design, build and ship production web applications, and I use AI-assisted development (Claude Code) throughout, reviewing and testing every change before it ships. My own product, Zera Fresh (zerafresh.com), is a TypeScript-based AI meal-planning platform built with AI-assisted development: recipes, grocery lists, pantry tracking and family sharing, xAI Grok for receipt parsing, voice pantry updates and recipe editing under usage quotas, Google OAuth, Stripe subscriptions (Free/Pro/Elite), AWS S3/SES, 70+ Jest tests, and production API security (Helmet, rate limits, ownership checks). I'm available for freelance and contract projects, remote, within 3 hours of CET, and I'm happy to work as a contractor.
