What I'm looking for

I'm looking for contract, freelance, remote full-time, or project-based work where I can improve backend reliability, integrations, real-time workflows, and AI-assisted production systems.

I've built backend-first full-stack systems for PT. Enerren Technologies, PT. Alugra's Bea Cukai TPS Online system, and AI-powered platforms for Shoppias Commerce LLC and Allpower .Ltd.

I design scalable APIs, real-time data flows, authentication and role-based access controls, AI-assisted workflows, and reliable database integrations. My work includes customs processing, legal client–lawyer communication, document extraction pipelines, ride-hailing and delivery workflows, field survey monitoring, and real-time trading systems.

I'm comfortable joining ongoing projects, working through legacy decisions, resolving production bottlenecks, and delivering practical end-to-end improvements under real-world constraints.
