At Bina Nusantara IT Division, I develop and maintain student-facing applications across ASP.NET Core APIs, React.js and Angular.js frontends, and SQL Server data layers. I designed a microservices architecture for authentication, student activity tracking, and community service management.
At Bitlabs Academy, I led product work on an LMS serving 150K+ active users. I improved page load speed by 40% with Redis caching and load balancing, and developed an AI-powered job matching system using OpenAI, LangChain, and FastAPI.
As a Software Engineer at Bitlabs Academy, I built LMS features including progress tracking and personalized learning paths; those features later drove a 25% increase in user retention. I also designed RESTful APIs and the database schema for the platform.
Earlier, I developed WhatsApp Business API integrations for customer success and payment automation platforms at SPE Solution, and a STEAM-based LMS at Praxis Academy. I’ve also built web applications with JavaScript, Vue.js, Node.js, Laravel, and Java Spring Boot.
