Selected Work

End-to-end systems you can inspect — every repo public, documented, and tested.

01Open source

LIMS-GO

A laboratory information management system — Go backend, React frontend, full containerised infrastructure and CI/CD.

problem
Laboratories need a system to manage samples, results and users, but most off-the-shelf options can't be self-hosted or reasoned about.
approach
Built a Go backend with a clean handler → service → repo layering, a React (TanStack) frontend, and Postgres + Redis + MinIO behind Docker Compose. Added role-based access, seedable data, CI on PRs, automated image builds and a manual VPS deploy flow.
result
A self-hosted fullstack system with documented architecture (CONTEXT.md, AGENTS.md), independent backend/frontend versioning, and a production deploy runbook.

02Open source

moodle-openrouter-plugin

An AI provider plugin routing Moodle's core_ai subsystem to OpenRouter — one API key for hundreds of models.

problem
Moodle's new AI subsystem needs provider plugins, but writing one against a pre-release (5.3dev) API is a moving target.
approach
Implemented a provider plugin pinning a specific Moodle commit, wiring three text actions through OpenRouter with per-action model/endpoint settings and a privacy-safe hashed user id. Shipped a full PHPUnit suite and an executable VPS deployment runbook.
result
A working, tested provider plugin — 26 tests, 152 assertions all green — and the docs to deploy it behind nginx + TLS.

proprietaryBiosync Lab Portal — Biosync Laboratorium Indonesia

Biosync Lab Portal

Biosync Laboratorium Indonesia

A full-stack platform for an ISO 17025 accredited lab — public site, customer portal and admin dashboard in one.

Build notes
problem
A lab needed both a public-facing site and an internal operations platform, with customers reserving samples and downloading certificates.
approach
Built a Next.js app covering public landing (SEO, i18n EN/ID, quotations), a customer portal (reservations, digital certificates, real-time chat, feedback) and an admin dashboard with 9 hierarchical roles. Added JWT auth over HTTP-only cookies, email verification, reCAPTCHA Enterprise and auto-generated PDF certificates.
result
A single production system used by the lab's staff and customers, with certificates generated on demand.

proprietaryOnehub Pod Booking Mobile App — Oneject Indonesia

Onehub Pod Booking Mobile App

Oneject Indonesia

A mobile application for booking shared office pods, with smart lock integration and third-party payment support.

Build notes
problem
A shared office provider needed a mobile app for customers to book pods, unlock them via smart locks, and pay through a third-party gateway.
approach
Built a NestJS backend with REST endpoints for booking, user management, and smart lock control. Developed a React Native mobile app for iOS and Android, integrating with the Tuya API for smart locks and Flip for payments. Implemented real-time notifications and booking confirmations.
result
A fully functional mobile app that allows customers to book pods, unlock them using smart locks, and make payments seamlessly.

About

Built the way I'd want to inherit it.

I'm Rafli Akhmad Baihaqi, a fullstack developer who leans on the backend but ships across the whole stack. I build systems the way I'd want to inherit them: clean layering, a documented data model, and deployment that's repeatable rather than magical.

The projects I'm proudest of are ones with real constraints — a laboratory management system with role-based access, a Moodle AI plugin pinned against a moving pre-release API, a safety-inspection platform. Those are where the trade-offs live: data modeling, concurrency, and getting it running in production.

I'm currently open to roles and based in Jakarta, Indonesia.
