What I'm looking for

I'm seeking a Lead, Staff, or Senior Software Engineer role with deep technical ownership.

At Mekari, I designed and built EM-Coder and EM-Loop, an in-house LLM agent orchestrator that removed manual release gates and enabled every merged PR to flow through an AI-assisted pipeline. It raised deployment frequency to five or more per week, with lead time of two days or less.

I also wrote production code and owned architecture for Mekari's Billing and Subscription System, which processes recurring revenue across all Mekari products. Before Mekari, I architected Go microservices at Grab serving merchants and agents across Southeast Asian markets. I'm seeking a Lead, Staff, or Senior Software Engineer role with deep technical ownership.
