What I'm looking for

I’m looking for a remote-friendly team where I can own end-to-end integrations and ship cloud-native apps and production LLM/RAG features, partnering closely with stakeholders and translating technical work for non-technical audiences.

I’m a Full-Stack Engineer with 4+ years building and shipping production systems for high-growth startups and enterprise clients. I work directly with stakeholders to turn ambiguous business requirements into reliable software, owning problems end to end—from scoping and design to deployment and production support.

I’ve delivered complex enterprise integrations (CRM systems, EHR platforms, payment gateways) and improved data reliability by resolving timestamp inconsistencies across services, standardizing date handling in Treasure Data pipelines. I’ve also built HIPAA-aware healthcare systems and led cross-functional teams on architecture, code reviews, and delivery quality—taking products from MVP to production serving thousands of users.

More recently, I’ve been building and observing LLM-powered features and RAG pipelines with LangChain and LangSmith on GCP, including OCR + LLM extraction workflows (Gemini-based). I enjoy translating technical work into plain language and helping teams adopt AI tooling through masterclasses.
