I’m a Backend Engineer with more than 3 years of experience building reliable, scalable services across banking, SaaS, and recruitment platforms. I enjoy working on systems that real people depend on every day, where performance, security, and data accuracy truly matter.

Most recently, I spent two years at Bank Rakyat Indonesia, one of Indonesia’s largest banks, developing RESTful APIs for BRIguna loan products on BRISPOT, an end-to-end digital lending platform used by field officers nationwide. Working in a Lumen-based microservices architecture handling over 800,000 requests per day, I implemented rate limiting and structured logging that reduced incident tickets by 10%, optimized database queries and indexing for 10–20% faster performance, kept a cross-service monitoring API under 10 seconds, and partnered with QA and security teams to harden access control against penetration testing risks.

Earlier, I built the backend of a SaaS transcription platform with Node.js, TypeScript, and Socket.IO that grew to 1,800 members, including real-time collaboration, multilingual transcription, and Midtrans payment integration.

I also completed the Apple Developer Academy, where I worked as an iOS developer and product/project manager, which shaped how I think about users, not just code.

I care about correctness as much as speed. I use AI tools to move faster, but I always validate outputs and data before they reach production. I’m interested in backend, platform, and data-heavy roles at product-focused companies, especially in fintech, SaaS, and education, and I’m comfortable working asynchronously with distributed teams.
