  • käyttäjän Grzegorz P. kuva Sketch for Arduino UNO (2DOF Motion Simulator) $120.00 USD

    “Very professional. Quick. Very good preceding. A step then check, next step check again and so on to the finish. I am very satisfied.”

  • käyttäjän Andy S. kuva Arduino Microcontroller TTL C++ Code (Master / Slave Communication) $125.00 USD

    “Fajar was very knowledgeable about the Arduino platform and serial commands and went above and beyond to get a fairly tricky bit of code working. He also documented his code very well, a sign of a true professional. The code was cleanly written and easy to follow and was even put together as a library to keep it easy to access and call as needed. Very much enjoyed working with Fajar and would like to do so again.”

  • käyttäjän Mauricio G. kuva Inclinometer $235.00 USD

    “It´s a pleasure to work with a professional individual that cares for your needs. Fajar is exactly that. He is clever, insightful, and clean in his work. Will hire again. !!”

  • käyttäjän Kwangwoo A. kuva Project for Fajar S. $1100.00 USD

    “He won't make you regret. I had to pay him bonus several times because he did really nice work”

  • käyttäjän Jorge S. kuva Modify code in C for ESP8266 €30.00 EUR

    “excellent! He understands quite well the needs”

  • käyttäjän Gray B. kuva Project for Fajar S. $430.00 USD

    “Fajar is an AMAZING developer. During this project, Fajar used his extensive developer skills to successfully complete the project on budget and on time. This project involved the microcontrollers (Arduino, Particle) Serial Communications, UART, Parsing Data, API's, hardware, and more - Fajar's code is CLEAN, logical, well structured, and very well written. When handling serial data, he always ensured a good data communication, including data validation, eliminating the possibility of data corruption. He is a superstar and reviewing documents and creating working code, even making very clean code before being able to test the code on a real device. My project involved him reviewing a lot of serial communication protocol documents, hardware documents, and then he needed to remotely test the system - something only a very advanced programmer could do as well as he did. He also is AMAZING at customer service, always very professional and gentle when things aren't working, and he always helped me find a new solution to my problems. He can also work very well with other developers, he has successfully been able to ask and discuss questions with my hardware partners, software partners, and my wider product development team. Fajar is the programmer you want on your team, a very smart, kind and hard working developer.”
