I design and build production-ready backend systems and APIs using Node.js, TypeScript, and NestJS. This includes RESTful and gRPC API development, event-driven microservices with Kafka, database design (MongoDB, PostgreSQL), authentication, and third-party or payment integrations.

I've built backend services for HealthTech, IoT, gaming, and e-commerce platforms, including GxP-compliant integration services for a scientific lab data platform. Great fit for startups needing a scalable backend from scratch, or teams looking to modernize a legacy service into an event-driven, microservices architecture.
