About Me

IoT Engineer with 5+ years of experience specializing in firmware development, telemetry, and maritime tracking solutions. Proven track record in architecting low-cost, high-reliability hardware-software ecosystems. Notably designed and deployed a low-cost AIS transmitter/receiver system for small-scale vessel tracking. Seeking to leverage expertise in embedded systems and team leadership to drive hardware innovation at your Company.

Job Experiences

PT. Imani Prima

Firware Engineer

Research and develop the firmware and hardware design for AIS (Automatic Identification System) transmitters and receivers. This product is utilized by maritime and ocean-fisheries institutions to track their mobile assets, such as vessels and barges, and monitor nearby maritime traffic.

PT. Multidaya Teknologi Nusantara (eFishery)

Electrical Hardware Engineer

Research and develop the hardware design and physics calculation for the e-feeder units, to calculate and predict the amount of fish food that should be poured into the pond automatically. Developed a new algorithm/calculation to detect how much fish food had been poured by measuring the motor's electric current consumption.

PT. Integrasi Sinergi Teknologi (INSITEK)

Intern

Research the minimum height and antenna configurations for the hot-air-balloon-based internet hotspot.

Notable Projects

IoT-Enabled AIS Receiver & Gateway

This project is an IoT-based Automatic Identification System (AIS) Receiver designed to capture marine vessel data and relay it to centralized monitoring servers. Built around an ESP32 and an STM32F4, the system features a web-based configuration interface for easy deployment and management.
