Hey there! I'm Hanif Naufal , a backend engineer from Yogyakarta, Indonesia with 4+ years of professional experience. I specialize in crafting robust, scalable systems that solve real-world problems—ranging from national government platforms to high-volume fintech and POS systems. I’m driven by purpose, fueled by Go, and passionate about simplifying complexity into reliable backend services.
About
I began my journey in software development as a mobile app developer, but quickly discovered my passion for backend engineering. Over the years, I’ve built systems that impact millions—implementing SSO platforms with OIDC & SAML, designing microservices architectures, and optimizing APIs and databases for mission-critical platforms.
Whether I’m developing notification systems at BPJS, revamping legacy monoliths into microservices for Korlantas Polri, or integrating RBAC into multi-tenant POS systems, I approach each challenge with a mindset of continuous learning and cross-team collaboration. My toolbox includes Go, PostgreSQL, Docker, Kafka, gRPC, Redis, and more. Beyond just writing code, I believe in writing code that lasts—maintainable, testable, and built for scale.
