About Me

I'm Johan Paul. You can call me Jp. It looks like "Jeep" but without the double e's.

1982: The Rise of Agent Double Eleven.

I am a senior developer — both web and non-web applications — and a former lead engineer. I work mostly with JavaScript and Python. As in, "That's Richard JavaScript and this is Theodore Python." At the moment, I'm rediscovering myself by working on projects and conducting research. 🔬

I have a degree in Electrical Engineering with a sub-major in Control Systems. Most students in that field pursued Robotics, but I chose to focus in the Active Noise Control (ANC) laboratory. For my final project, I implemented analogue ANC on headphones. First of all, it was an audio-acoustic-signal related subject. Second, large room. Third, large room.

Back in college years, I had an awkward experience in the laboratory. I played a nylon guitar out of boredom and confusion like a champ, alone. Suddenly, in the middle of my fingerpicking smooth-pop serenade, my professor barged in. His office was far away from the laboratory. So, I suppose he was checking out the noise. As in, "This is a noise cancellation laboratory, why... that?"

So then, he nodded and smiled, as for me too. "Outside academia fascination is yours", he perhaps concluded. I passed the final project presentation with grading negotiations punctuated by mutual wit and amusement.

The guitar knowledge I got first came from the intensive courses I did, starting when I was in my 5th grade. My sister enrolled me to the classical guitar course back then, Yamaha licensed course.

After I graduated from college, the first thing I did was auditioning for a pop guitar instructor. I was accepted as an electric guitar instructor (default) — but also taught acoustic/nylon (fingerstyle) by request — Yamaha licensed.

As time went by and I got older, I developed the habit of trying to translate what I heard into my guitar playing. It's something I still do. When I hear something that catches my interest, I try to replay the notes. It usually starts with humming or whistling, since I don't always have my guitar with me.

I taught guitar class from the middle of 2006 to around 2012 — electric, classical, and acoustic guitar classes. I also performed at places.

For some reason, I also play other musical instruments besides guitar. I guess it's because I just really enjoy music.

From an early age, I've liked drawing cartoons, or just drawing in general, as you can see from the characters I've included here. 🖼️

My Other Interests

Chess is my amateur interest, it's something I enjoy and practice regularly, but not at a professional level. Thanks to Lichess, I can watch games, study and broaden my knowledge about it.

I trained in various martial arts back in my teenage years. I have knowledge and experiences in taekwondo and karate plus a bit in kempo and aikido.

I did plenty of tameshiwari and gyeokpa back then — controlled breaking of inanimate objects using precise martial strikes. It was simply part of the drills, quite a rigorous training.

But then, I realised, hm, those bottles, bricks, planks, I can build meself a pub.

Cooking is interesting to me. I know one cuisine — fried eggs.

Did you know the taste came from the oil?

I did fry eggs with polytetrafluoroethylene (Teflon) coated pan — no oil. I tasted the result. Well I never!

If there's a good honest boiled or steamed meal nearby, I'll take that over fried every time. 😄👍

I observe history, cultures, and languages. 🧐 They're grand — some of the tensors holding the cosmos together.

That's a brief about me, Jp. Thank you. 🫡
