About Me

Backend engineer with 3+ years building scalable, secure systems in FinTech. I've led the development of Mobile Banking and Loan Management platforms at MAMPU.IO — serving 12,000+ users with thousands of monthly transactions across rural banks and cooperatives in Indonesia.

I specialize in service-oriented architectures, event-driven systems, and integrating core banking, payment gateways, and digital identity services. I turn complex business requirements into robust, production-ready backend solutions.
