About Anton
Senior React + Rails Engineer - SaaS Features & Integrations
Warsaw, Poland - 8:16 am local time
14+ years building web products with React, Rails, TypeScript, and PostgreSQL. Six years as the core engineer on a production SaaS platform: features end-to-end, performance, CI/CD, keeping releases shipping.
What I'm best at:
→ Jumping into an existing codebase and becoming productive in days, not weeks
→ Turning vague requirements into shipped, tested, production-ready features
→ Hunting down hard bugs - database, API, frontend, infrastructure
→ Third-party & POS/payments integrations (Toast, Square, Clover, Stripe, REST/GraphQL, webhooks)
Async-first, clean tested code, clear communication, no hand-holding.
Previously: Senior Engineer at Popmenu (restaurant tech, POS integrations on a platform serving 10,000+ restaurants). 6 years on a production SaaS product.
Open to feature work, bug fixing, legacy rescue, and integrations - hourly or fixed-price.
