About

Professional summary

I am a Senior Full-Stack Engineer with more than 10 years of experience building, deploying, and operating production web applications across e-commerce, healthcare, media, enterprise, and government-related projects.

I specialize in TypeScript, Next.js, React, Node.js, Prisma, and PostgreSQL. I build end-to-end platforms, from customer-facing interfaces and backend APIs to administrative systems, data models, and operational workflows.

I have strong cloud and platform engineering experience on Google Cloud Platform, including Cloud Run, Cloud SQL, Secret Manager, IAM, Cloud Build, load balancing, and multi-environment deployment strategies. I also work with AWS Amplify, Docker, GitHub Actions, and Cloudflare.

In my current role, I own the full-stack development and GCP infrastructure for a production e-commerce platform. My work includes architecture planning, CI/CD automation, security hardening, secret management, payment and logistics integrations, and reliable cloud operations.

I have experience leading technical planning, collaborating in Scrum teams, improving database and reporting workflows, and coordinating product delivery. I am based in Indonesia, work remotely in UTC+7, and am open to remote opportunities worldwide.

I value secure, maintainable, high-quality software delivery and use an AI-augmented development workflow to move quickly while maintaining code quality and operational reliability.
