I design, build and ship whole products — web, mobile and the backends behind them.
Three production platforms — an AI visual studio, a music streaming service and a consent SDK — built end-to-end by one engineer: .NET and Go backends, React web apps, and ten React Native apps on the App Store.
GET /expertise
One request, top to bottom — every layer below is something I've built and run in production.
Shipped App Store and Google Play apps — AI photo tools, streaming, utilities — with in-app purchases, push notifications and native modules.
SaaS studios, developer portals and admin panels: state management, real-time updates, i18n and fast rendering.
Enterprise-grade APIs with JWT auth, rate limiting and OpenAPI docs — including a public API productized with keys and usage billing.
Production backends in C#/.NET and Go: modular monoliths, microservices, worker processes and message-driven pipelines with RabbitMQ.
High-performance caching, full-text search with Elasticsearch, and real-time processing for IoT fleets of 10K+ devices.
Containerized deployments with CI/CD automation, S3/CDN pipelines, and observability across every service I run.
