ABOUT ME

Android • Backend • IoT • DevOps • Real-time Systems


semangat emoji I am a full-stack developer working across Android, backend, embedded systems, and hardware-focused product builds. I focus on practical engineering: reliable software, maintainable architecture, and devices that are meant to work outside the prototype stage.

My strongest area is Android development with Kotlin. I build apps for utility, IoT, and consumer use cases with attention to performance, clean structure, and interfaces that feel deliberate instead of generic. On the web, I work with HTML, CSS, Tailwind, and JavaScript to ship responsive frontends and internal tools.

ngantuk emoji On the backend, I primarily use Python with Flask and FastAPI, and I am comfortable building service APIs, automation workflows, and Linux-based deployments. I also use Django, TypeScript, and Ktor when they fit the system.

I also work deeply in IoT and embedded systems, especially ESP8266/ESP32, MQTT, Home Assistant, and OpenWrt. That includes firmware work, reverse engineering, board-level troubleshooting, and turning repurposed hardware into stable local-first products.

Beyond software and electronics, I design physical enclosures with CAD and build custom parts with 3D printing. That lets me handle the full path from firmware and application logic to the final hardware form factor.

sibuk emoji I also maintain self-hosted infrastructure using Linux, Docker, and related tooling, and I regularly work with PostgreSQL, MongoDB, Firebase, Git, and real-time systems such as WebSocket.

Another area I am comfortable with is reverse engineering, particularly on Android and embedded devices. I use it to understand undocumented behavior, recover unsupported hardware, and extend systems beyond vendor limitations.

ngamuk emoji I build practical systems that connect software, networking, electronics, and physical product design.
