Career Profile

I am someone who likes tinkering and working with complex problems. My interests are Space, Green Energy, and Computer Networking. I have experience in AVR, MSP430, and STM32 Microcontroller (8-bit & 32-bit) as well as FPGA from Xilinx. My objective is to join a reputable company and become a member of a professional engineering team that later can change the world for a better living in the scope of technological breakthrough.

Experiences

Embedded Software Developer

2018 - Present
FEV Norddeutschland GmbH

FEV is an Engineering service provider based in Germany and have its subsidiaries all across the world. Automotive projects are the main core of what people do in FEV. I work here as a Software Developer to develop an Engine Control Unit (ECU) software as well as testing it. I am also doing the implementation of the Fixed-point arithmetic in a floating point software. For those work I use a proprietary tool such as ASCET and TPT.

Hardware Developer

2013 - 2014
Center for Robotic and Intelligent Machines (CRIM)

CRIM is a research institute at Surya University. At that time they are working closely with Indonesian Army to develop a drone. The drone's objective is to autonomously map a certain area. My task here is related to the electrical engineering division such as power distribution, and motor control.

Embedded Software Developer

2012 - 2013
EDMI Shenzhen

EDMI is a subdivision of OSAKI Japan. Shenzhen branch of EDMI is mainly dealing with production and research. As a transfer engineer from PT. Metbelosa, my job here is to adapt the production process to Indonesian branch as well as helping on the research of a new digital electricity meter. I was tasked to help the software division to develop an embedded system firmware on a proprietary metering System on Chip (SoC) in Embedded C++. I also had a chance to learn Chinese language and culture

Embedded System Developer

2011 - 2012
Metbelosa PT

PT. Metbelosa is a Subdivision of Osaki Japan situated in Jakarta. The purpose of the company is to fulfill the electricity meter demand of Indonesia. It is the country's policy that requires a certain percentage of product that is going to market in Indonesia is made in there. My job there is to optimize the electronic meter’s production process. At the time, Indonesia is in a transition period from analog electricity meter to the digital electricity meter. Therefore, I also took part in the product development of digital electricity meter.

Intern

2010 - 2010
Harman Automotive Division

This company which situated in Stuttgart, Germany is a subdivision of Harman International. Their task is to design a new generation of car infotainment system. Their customer includes Mercedes Benz and Audi. I work there as part of the 6 months international internship program from Swiss German University. My task there includes building a testing equipment, testing a prototype unit for a car infotainment system, and documenting my work. In this internship, I got a chance to learn German culture and language and experience on working abroad.

Intern

2008 - 2009
Siemens Indonesia

I had a training here as part of the mandatory training program from Swiss German University. The Vocational Training Center of Siemens Indonesia is located in the city Cilegon. I learned the following: basics of electricity and cabling systems, electrical measurement systems, electronic components and low voltage protection electrical, cabinet installation, and the operation of traditional lathe and milling machine as well as CNC lathe and milling machine.

Projects

Home Automation - This has been on my bucket list for a long time. I use a solution offered by folks from HomeAssistant and a RaspberryPi for my implementation. I can now log the temperature and humidity in my room. The next goal is to log my electricity use in my home.
Flip Clock - Inpired by those fancy nixie tube clock. I created something similar using a gas station display that use electromagnet to activate each segment. After carefully choosing the component, I designed the PCB and finally order it for fabrication. Then I proceed to solder all the surface mount component using the oven method. For those who is interested, sources can be found here.
This Website - I did this while I'm searching for job after I graduated from TU Berlin because I want to be productive in this downtime. It's been a fun project and I've learned a lot of new things! From writing HTML and CSS to hosting a website.
Master Thesis - Solar Charge Regulator - I did this project in collaboration with PT Scientist GmbH, Berlin. This project supports the Lunar Quattro Rover that was part of the Google Lunar X-Prize. I designed a charge regulator that have a Maximum Power Point Tracking (MPPT) capability. Worked in PCB prototyping with Altium Designer, parts selection, ARM programming on STM32 F4 with Embedded C++.
Home Network Security - I've built a pfSense router using an old Dell PC. The main function is to achieve 100Mbps speed of VPN tunneling with 128-bit AES encryption. This cannot be done by a traditional router as it requires more computing power. Additional feature such as traffic shaping and the proxy server is also useful.
Aeromodelling - I have a dream of becoming a pilot. But before that, I want to fly a model airplane. The model airplane was made of foam board and hot glue. I learned a lot about the electric motor, wireless communication, airfoil, lipo battery, propeller, and not giving up. Trust me, I crash a lot. Video
Arduino based Weather CanSat - The CanSat was launched to measure atmospheric data. In this University project, I was responsible to develop the sensor electronics and software in the CanSat. Worked in wireless communication and data interpretation.
Sensor Array for the Fluid Dynamic Actuator (FDA) - FDA is developed by TU Berlin to replace reaction wheel as satellite attitude control. The sensor array is used to demonstrate the working principle of the FDA. Worked in sensor data fusion, control algorithm, multicultural team.
Bachelor Thesis - DC-DC converter using an FPGA - The project is done side by side with the “Indonesian Agency for the Assessment and Application of Technology”. This is a closed loop system with a Spartan 3E FPGA as the core. The system is used to regulate the power from the solar panel at a remote "Cellular Tower". My main task is to write a functional program for the FPGA with VHDL as the language. Worked in power electronics, sensors driver, "ISE Design Suite" by Xilinx.
Point to point wireless communication - The objective of this project is to create a network between two building across the road. This is not doable by copper cable as it will be illegal. That is why I choose to use a product from Ubiquiti. I learned about networking, antenna pointing, and working with a client.
“Wi-Fi controlled robot” using Arduino - It is a 3-wheeled robot that can be controlled with any Wi-Fi enabled device such as laptops and smartphones through a web interface. The robot uses Servo as the actuator, wireless router as the communication platform, and Arduino as the processing unit. Worked in CAD design, computer networking, HTML programming.
“Wall Kissing Robot” using 8051 - It is an exercise to practice close loop control algorithm using a motorized car with rangefinder sensor. The task of the car is to slowly stop if it detects any obstacle in front of it. Worked with the control algorithm, Keil C51, H-Bridge circuit.

Organizations
