Hi, my name is Fajrul Falah a.k.a Fajrul Fx 👋

I have a diverse range of skills and experience in physics, education, and media.

I mainly identify myself as:

  • Science Communicator – I am actively creating popular science content on various platform such as books, Youtube, Instagram, and Tiktok with a total of more than 500k+ subscribers/followers.
  • Physicist – I’ve worked at DTECH-ENGINEERING Company as physicist with the responsibility to do physics calculation for development of various tech products: from drone to electric vehicle.

Work Experiences:

    (Jun 2019 – May 2021)
    I did physics analysis and calculation for various technology products: from the battery, drone, electric vehicle, and many more. Here are some highlighted projects:
    • Physics analysis and FEM (Finite Element Method) simulation for the development of new generation 5-axis CNC (Computer Numerical Control) Milling.
    • Theoretical work on the development of 4-stroke special engine for racing bike
  • Founder and CEO, Saintif
    (2017 – 2021)
    Saintif is an online popular science media that focus to bridge the gap between science and society. I started this project with my friends while in college, start small and write two books, and then it grew rapidly to 10M+ website visitors an 70K+ Instagram followers. Currently the team is focused on supporting the production process on my Youtube channel “Fajrul Fx”.
  • Physics Laboratory Assistant, Bionano Material Lab, Diponegoro University
    (Aug 2018 – Jul 2019)
    • Doing synthesis, analysis, and simulation of various materials such as MnO2 nanorod and Carbon Nanotube as electrode for battery/supercapacitor
    • Assisting lab visitors in designing and conducting experiments
  • Expert Physics Problem Solver, Upwork
    (Jun 2017 – Aug 2018)
    I worked as a physics problem solver, helping clients from all around the world to solve physics problems. From as simple as physics homework, creating physics exam question, to the real physics problem in the industry.
