What I'm looking for

I seek backend or fullstack roles where I can build scalable, testable services, work with resilient architectures, and continue learning through real product work in collaborative teams.

I am a backend developer focused on designing scalable, maintainable architectures using Node.js, NestJS and TypeScript. I emphasize strong typing, modular systems, and resilient service design to deliver production-ready backends.

My projects include a multi-tenant, event-driven notification engine with Redis, BullMQ, PostgreSQL and Cockatiel for resilience, and a flights search microservice integrating Amadeus APIs with Redis caching and OAuth2 token management.

I have built layered, testable services using Express, MongoDB and JWT for authentication, and follow best practices such as DTO validation, structured logging, circuit breakers, and idempotent delivery semantics.

I am transitioning from HR into software, continuously learning through formal studies and bootcamps, and seeking backend or fullstack roles where I can contribute to real projects and grow professionally.
