I will build backend systems, apis, and automation scripts

I build backend systems and automations that hold up in production not

just code that passes a demo.

Recent work includes:

- Microservices (Go) for a telco mobile app, including payment gateway

 integration (DANA, GoPay, OVO, ShopeePay) and real-time messaging (MQTT)

- A booking platform REST API (Node.js/Express) with JWT + OAuth2

 authentication (Google, Facebook), MongoDB, and AWS S3 file storage

- Workflow automation (Power Apps/Power Automate/RPA) replacing a fully

 manual multi-stakeholder approval process

- A Python automation bridging two systems with no native integration,

 syncing attendance data via API into a payroll dashboard

What I can build for you:

- REST APIs (Node.js, Go, or Python)

- Authentication systems (JWT, OAuth2, session-based)

- Third-party API/payment gateway integration

- Workflow automation & data sync scripts

- Database design (MongoDB)

- Bug fixes and code review on existing backend codebases

I also hold a CAPM certification, so you'll get clear documentation and

status updates not just a code dump at the end.

Send me your requirements and I'll scope it before we start.
