What I'm looking for

I’m looking to build scalable, user-centric products in fast-paced teams—writing clean, well-tested code, automating workflows, and applying AI responsibly while mentoring engineers and owning backend/devops reliability.

I’m a software engineer with over seven years of professional experience, evolving from deep backend work into full-stack delivery with a strong DevOps foundation. I thrive in fast-paced startup environments, and I’m driven by clean, well-tested code and measurable efficiency through automation.

As a former Backend Team Lead, I focused on mentoring colleagues and streamlining workflows while maintaining high standards for code quality, system stability, and performance. I’ve led migrations and modernization efforts, including moving infrastructure from AWS to GCP, and transitioning legacy components into microservices for improved uptime and scalability.

More recently, I’ve been integrating AI extensively into daily development—architecting AI-native products and building capabilities like LLM-powered data pipelines, pgvector-backed semantic search, and context-aware AI assistants with persistent user profiles. I’m excited to keep building scalable, high-performance, user-centric solutions that balance innovation with reliability.
