What I'm looking for

I want to build backend and AI/LLM systems that ship reliably in production—like agentic workflows, RAG features, and robust REST APIs—while owning performance validation, scalable architecture, and CI/CD quality that reduces release risk.

I’m a Software Engineer II with 3.5+ years building Java/Spring Boot backend systems and enterprise REST APIs in production. At Serko, I designed and shipped LLM-integrated features, including a Policy Compliance Agent and an API Readiness Evaluator, and I also built a RAG-based document Q&A system as a personal project using Python, LangChain, and ChromaDB.

I lead by measurable impact: I extended 5+ enterprise booking workflows, evaluated Redis and Kafka for booking-notification pipelines, and ran JMeter performance validation with my team of 4 engineers to ensure release metrics stay within defined thresholds. I also drove NDC enhancements and improved developer efficiency by automating Lombok injection across 200+ Java classes, cutting boilerplate by 14% and saving ~3 engineer-days.
