Headline
Full-Stack Engineer
Software engineer with 5+ years building production web applications, APIs, scraping pipelines and automation tools for startups, agencies, government clients and event organisers across Indonesia.
My focus is the backend: REST API design with Laravel, NestJS and Fastify; relational and document data layers (PostgreSQL, MySQL, MongoDB); container deployment; and the unglamorous infrastructure that holds it all together. On the frontend I work primarily in SvelteKit, with React/Next.js when the engagement calls for it.
I work calmly, prefer reversible decisions, and treat code as something a teammate will need to read six months from now. Open to selective client engagements and long-form collaborations — especially around web scraping, automation, and AI-assisted workflows.
