ABOUT ME
Jedi Master of JavaScript
Jedi Master of JavaScript

Codementor has been a great experience so far. Every sessiosn is a challenge and there's always a unique problem to solve. Whether it's just explaining how a piece of code works or a deep debugging session, I'll be able to help you.

I have 15 years of JavaScript professional experience including 10 years of contracting with top digital agencies and finance consultancies in London. Plus full stack(TypeScript/Node/Postgres) expience in a crypto exchange.

Currently devoted to my personal projects(full stack JavaScript/TypeScript/Postgres/TimescaleDB, and Go). My smaller projects are open source, usually as NPM modules and the big ones will become OS when they're mature enough.

My Stack Overflow https://stackoverflow.com/users/696535/pawel
and Github https://github.com/DVLP/

Some of my current projects:
https://font.skin - GPU text effects rendered in real time using my bespoke WebGL engine. I have working prototypes of Three.js, Babylon and Playcanvas integrations.

https://fin3d.com - An overwierview of S&P 500 stocks with daily updates. I used Three.js for rendering. All the bars are rendered in a single draw call so having multiple price changes per second is still butter smooth. The overlayed prices and labels are using a custom Canvas renderer so showing even 100 price changes at once doesn't slow anything down. It used to have real-time updates with price bar animations but Yahoo Finance recently closed their API.

I've spent tens of hours in 3ds Max, not as many in Blender and obviously hundreds of hours in Photoshop as a front end dev.

I spent hundreds of hours profiling and optimizing JavaScript code in my game engine. Turns out most programs can easily run 10x faster, and with some more effort and rewriting, 100x faster

Back in the day (2009/10) I also built the first popular web fonts website https://fontsforweb.com which I published before Google Fonts existed. At some point searching "web fonts" was showing it on the first place. I think "web fonts download" or "free web fonts" still show it as the first. It's still functioning in a low-maintenance mode with just a few hundred visits per day. It's using PHP with Zend Framework so I can help you with that too.

PHP was the beginning of my web-applications building passion and I've written tons of code using it. Zend Framework helped me to get things organized and I have an active website with millions of monthly hits running on it.

Increase localStorage size 10 times or more! Very easy to use and potentially much faster than native localStorage!
