I’m looking for remote software engineering roles where I can work across backend systems, APIs, automation, integrations, and full-stack product development. I’m especially interested in teams that value ownership, practical problem-solving, maintainable systems, and engineers who can work independently across different parts of the stack.

Full-stack and backend developer building business applications, workflow automations, and AI-assisted systems since 2019.
IndonesiaWhat I'm looking for
Since 2019, I’ve worked independently as a freelance full-stack and backend developer, building and maintaining business applications, backend services, and REST APIs with Node.js, TypeScript, and PostgreSQL.
I’ve developed business-process automations for CRM workflows, custom-field synchronization, invoice and transaction recovery, reporting, and third-party integrations. I also troubleshoot existing applications by tracing production issues, validating business logic, and shipping targeted fixes through GitHub pull-request workflows.
My projects include MCP-Web-Curl, a TypeScript and Puppeteer MCP server and CLI for AI-assisted web content and API access, and a QR-based field inspection and evidence management system. I’m also interested in AI-assisted developer tooling, web automation, and information systems.
