I’m a Senior Software Engineer with five years of experience building distributed systems, agentic AI applications, and full-stack platforms that solve real-world problems. I’ve been lucky to work with top companies like Ethos (an insurance tech startup) and Grab, where I consistently delivered high-impact projects and earned recognition as a top performer. I thrive on leading teams, designing scalable systems, and mentoring junior engineers to help them grow. I have hands-on expertise in agentic AI concepts, including context engineering, memory management, retrieval-augmented generation (RAG), vector databases, and tool integration. Feel free to reach out for a chat or coffee — always happy to connect!
