01 / Work

Impact a hiring team can verify.

My work sits across product delivery, platform reliability, and AI integration. The common thread is ownership: understand the business need, ship the system, and improve how the team works after release.

03 / About

What I bring to a team.

I am most useful in teams that need an engineer who can move between product context, technical detail, and release pressure without losing the thread.

Based in Indonesia. Remote-ready. Strongest fit: senior fullstack roles that need product engineering, AI-assisted workflows, and infrastructure ownership.

I work across frontend, backend, cloud, and product boundaries. My strongest contributions happen where those boundaries meet: AI features that need reliable data flow, Rails systems that need performance work, and interfaces that make complex workflows easier to operate.

I have worked in small teams, remote teams, and cross-functional product groups. I am comfortable writing RFCs, mentoring interns, partnering with designers, and taking ambiguous product requirements into production.
