Software engineer building reliable systems and AI agents.
I'm a software engineer from Kuala Lumpur. For the last five years I've built production systems in fintech and consumer tech — distributed workflows, reliability, and observability at companies like Grab, Xsolla, and StashAway. These days I'm focused on building AI-agent applications on top of large language models: retrieval, orchestration, guardrails, and evals. This is where I write about what I build.
