ABOUT WOJTEK ROMANSKI
I’m an AI-first Lead Full-Stack Engineer working mainly with TypeScript, React/React Native, and Node.js. I treat AI as part of my engineering stack - constantly experimenting with tools and workflows to increase delivery speed while maintaining the level of quality I’d confidently sign off in production. I care about building systems that move fast without degrading over time.I often join projects early or at messy transition points, shaping vague requirements into concrete architecture and shipping production-ready features quickly. I’m comfortable owning work end-to-end, from UI and API design to deployment and production support, making pragmatic trade-offs that fit the stage of the product.My work spans data-rich applications, APIs (REST and GraphQL), mobile and web clients, and cloud infrastructure. I’ve built authentication microservices connecting multiple systems, designed data aggregation layers for custom dashboards, implemented DSP integrations with playlist synchronisation across providers, and stabilised legacy serverless services to restore reliable releases.Technically, I’m strongest in the TypeScript/Node.js ecosystem, React and React Native, PostgreSQL, and cloud-native stacks (AWS, GCP, Supabase). I’ve worked in event-driven environments, built integrations with third-party systems, and care deeply about performance, clean data models, and long-term maintainability.I work well in strong teams, but I’m equally comfortable taking ownership and driving things forward when needed.
