At President University Foundation, I engineered a multi-tenant School Information System from scratch using Golang, PostgreSQL, and Redis. It’s used across all four President schools, with location-based access control for each branch.
I also developed a Computer-Based Test system for student admissions and built reusable form and grid libraries used across the system. I built career.president.ac.id, an internship portal where President University students can find and apply for opportunities with partner companies.
At Bahaso.com, I developed and maintained the Bahaso v2 web interface and platform using Nuxt.js, PHP, Golang, and Moodle. I improved backend response times by 35% by restructuring SQL queries, adding indexes, and using caching.
At LIFEPACK.ID, I developed a real-time chat consultation feature with WebSocket and Socket.io, and contributed to the migration from a monolith to microservices. Earlier, at CHAMELEON TECH, I developed backend services and APIs with Node.js and Golang, and implemented CI/CD pipelines with Jenkins.
