Description

Senior full-stack and mobile engineer with 18 years shipping production software end to end, with genuine depth in three areas that rarely overlap in one person: full-stack web, native and cross-platform mobile, and the cloud infrastructure behind them. I take products from prototype to production, solo or with a team.

My core stack is React Native, React, Node.js, TypeScript and GraphQL, and I write the native iOS and Android bridges in between (Bluetooth hardware, MDM-managed devices, USB/Bluetooth printers). Earlier I shipped native iOS in Swift and Objective-C and cross-platform apps in Flutter.

On the infrastructure side I design and operate backend and streaming systems on GCP and AWS, with hands-on CI/CD, Docker, Kubernetes, observability (Prometheus, Grafana, OpenTelemetry) and mobile release tooling (Fastlane, OTA updates).

I increasingly work AI-augmented: building agent-based workflows and small internal tools and wiring LLM APIs into products to ship faster across all of the above.

I'm currently a senior engineer at Starship Technologies (autonomous delivery robots), building and owning the internal web, mobile and backend tools that run the fleet across 9 countries, and I'm available for freelance projects in full-stack web, mobile apps and cloud infrastructure.
