What I'm looking for

I’m looking to build and scale cloud-native, AI-driven platforms end-to-end—owning architecture, shipping reliable APIs and pipelines, and partnering cross-functionally while mentoring teams.

I’m a Senior Software Engineer with 10 years of experience building scalable cloud-native platforms for AI-driven, data-intensive systems. I take ownership from architectural design through production monitoring, partnering with cross-functional teams to deliver real-world engineering solutions. I also mentor junior developers and interns through technical guidance and professional mentorship.

Across my roles, I’ve designed distributed backend services with Django and FastAPI, built TypeScript/Node.js orchestration and internal API gateways, and implemented event-driven pipelines with RabbitMQ and AWS SQS. I’ve led AI-powered backend workflows using LangChain and LangFuse for tracing/observability, and built Retrieval-Augmented Generation (RAG) pipelines for semantic search, contextual Q&A, and AI-assisted analytics with vector search. I prioritize reliability and performance—establishing testing standards (often 90%+ coverage), strengthening security with JWT/OAuth2 and RBAC, and improving deployment speed through CI/CD with Jenkins, Docker, and Kubernetes.
