I’m Puvaan Raaj, a software engineer from Malaysia. My center of gravity is backend engineering: APIs, queues, workers, observability, infrastructure, and tools that make engineering teams faster.
Right now, my work has four lanes: production backend ownership, legacy application migration, agentic AI in the cloud, and serving as Fiuu’s Claude DRI. I do active AI research alongside this — reading papers, running experiments, tracking what's moving in the field. That means I care about the code path, the rollout path, the research frontier, and whether other engineers can actually use the thing after the first demo.
The previous version of this site listed too many implementation details from company work. This rebuild turns that into a cleaner professional narrative: payment enablement, cloud modernization, platform reliability, developer productivity, and AI research.
Outside structured work hours, I'm still at it — personal AI projects, reading research papers, building small tools to stress-test ideas. Most days run 12–14 hours. The curiosity and the craft blur together. Receipt parsing teaches product privacy. A password generator becomes a post-quantum crypto lab. A paper on attention mechanisms becomes a weekend implementation.
