What I'm looking for

I seek backend or cloud-focused roles where I can design scalable, secure APIs, lead technical solutions, integrate AI, and work with collaborative, remote-first teams.

I am a backend developer with 12+ years building scalable, secure APIs using Node.js, Java Spring Boot, and Python, and a strong focus on cloud-native architectures and AI integration. I advocate for clean architecture, Domain-Driven Design, and test-driven development to deliver maintainable systems.

My experience spans serverless and containerized solutions on AWS (CDK, Lambda, Step Functions, API Gateway, SQS, EventBridge, ECS) and integrating LLMs with LangChain, LangGraph, and LangSmith to add AI capabilities to products. I have a proven track record working remotely with US-based teams and leading projects end-to-end.

Notable achievements include leading serverless and containerized projects, maintaining high test coverage, and delivering microservices in Java, Node.js (TypeScript), and Python for production systems. I hold certifications in generative AI and cloud security and authored a publication on Ant Colony Optimization.
