I'm a full-stack engineer and technical lead based in Jakarta.

Most of my day-to-day work lives in private enterprise repos, so this profile does not show the full picture. Lately I’ve been working on web infrastructure at Esco Lifesciences Group: supporting 100+ internal and external web properties, mentoring a team of up to 9 developers, and moving legacy deployments into a cleaner k3s setup across Azure and Cloudflare.

Before that, I worked as a full-stack developer at RFIDiom, where I built and maintained 200+ REST APIs across two products with a remote multinational team.

I like working near the parts of software where product, backend, infrastructure, and developer experience meet. Good systems, useful tools, fewer “why is production like this?” moments.

• Web platforms and customer-facing portals
• Backend APIs and SQL-backed systems
• Internal tools that help teams move faster
• Kubernetes, deployment workflows, and CI/CD
• React, Node.js, PHP/Laravel, and Java/Spring Boot
• Small AI and automation experiments

• Cleaner developer workflows
• Practical infrastructure for small-to-mid-sized teams
• AI-assisted tools for boring everyday problems
• Turning vague business requests into working software
