01. About Me
I'm an electrical engineer with a passion for building things that blink, move, sense, and talk to the cloud. My work spans the full hardware stack: analog front-ends, digital logic, power electronics, and the embedded firmware that brings it all together.
Over the last six years I've designed audio electronics for a company, IoT devices for wireless sensor networks, and custom flight-controller boards for personal projects. I care deeply about clean schematics, EMC-friendly layouts, and designs that survive real-world abuse.
When I'm not at the workbench, you'll find me reverse-engineering old electronics, lecturing about electrical circuits, hardware design, automation and robotics, contributing to open-source hardware and edge AI, or flying drones and operating robots I built myself.

04. Featured Projects
Electric Guitar Footswitch Controller With BLE
Industry project from a previous company: a Bluetooth Low Energy (BLE) device that lets players configure electric guitar modes wirelessly from a smartphone app. Deployed to end users — not left as a lab prototype.
Low-Power Water Meter Monitoring Device
Developed a water consumption monitoring device using a water flow sensor to measure and track water usage. The system focus on low-power operation and implemented using RTOS to support efficient task management and resource utilization.
Custom ESP32
Developed custom smaller ESP32 Development Kit board for better PCB density.
DIY Drone using Beta Flight Firmware (Progress)
Developed an experimental drone flight controller using an ESP32 Dev Kit, based on an open-source project available on GitHub. The system was implemented on a quadcopter platform using the DJI F330 frame, involving embedded software and flight controller hardware integration.
Autonomous Mobile Robot (Progress)
Developing an autonomus mobile robot based on ESP32 using microROS to support cummonication and integration within ROS2-based robotics architecture. The current prototype utilizes an IMU and wheel odometry for motioin sensing and state estimate. Future development plans include integrating a 2D LiDAR sensor and a single-board computer (SBC) to expand robot's perception capabilities and more support advanced autonomous navigation.
Kit DC Motor with PID Controller
Developing DC Motor with PID Controller for support Control System Practicum, using ESP32 Dev Kit as the Microcontroller.
05. Experience
2025 — Present

2021 — 2023
Research & Development Electronic Engineer
PT. Meiloon Technology Indonesia
During my experience as an Electronics R&D Engineer, I was responsible for designing electronic circuits and PCB layouts to support product development. I built, tested, and validated electronic prototypes against technical specifications, while performing hardware troubleshooting and root-cause analysis to identify and resolve circuit issues. I also prepared technical documentation, test reports, and design revision records to maintain clear and traceable development processes. Throughout the project lifecycle, I collaborated with cross-functional teams to support product development, coordinate testing activities, and implement design improvements to enhance product performance and reliability.
2019 — 2023
Mechanical Technician
PT. Evoluzione Tyres
Responsible for performing preventive maintenance and routine servicing of Tyre Building Machine equipment, including maintenance scheduling, machine cleaning, component modification, and mechanical assembly to maintain equipment reliability and operational efficiency.
2023 — 2025
Master of Electrical Engineer
Universitas Katolik Indonesia Atma Jaya
Thesis on Analysis of a Fuzzy Logic-Based Water Circulation Pump Controller in an Aquaponics System.
06. Contact
Let's build something.
Whether it's a new board that needs designing, firmware that needs writing, or a product that needs taking from napkin sketch to production — I'd love to hear about it. If you're hiring a hardware engineer, my CV is one click away and I'm happy to chat.
