Cumulus1 is a successful tech startup based in the UK. We transitioned from delivering a distributed computing platform to a virtual desktop platform under the DaaS model this year. I was the technical lead during the development of our distributed platform and later transitioned to consulting where I look at new ways to help grow the company.

Technical Lead

Occasional freelance programming and web design projects.

Here are some:
- An electronic school diary for a local high-school
- A website for an online Mandarin tutor - UnderstandChinese.com
- A website for a gamer and streamer V仔獸 - OctoberVivi.com
- A landing page for PrExport - a service that can quickly export from Premiere Pro

Software Engineer

ASC is a software agency based in London. We successfully served many types of clients by developing software from web applications through 3D visualizations to distributed systems. The company employs only a handful of people so I filled multiple roles: Software Engineer, Project Manager and Technical Lead (when on a team) on an as-needed basis. It was chaotic but in the end, we still delivered results.

A language I fell in love with that later broke my heart (unfortunately no space to share that story here). Recently I built and maintained a project of around ~60k lines of code in the financial industry. Before that Rust was my go-to language for 3 years for both work and personal projects.

Here's some stuff I made with it:

- A project of over 60k lines of code that is deployed and runs live in the financial industry
- A game console emulator based on CHIP-8 and made for teaching purposes
- The entire backend of the distributed computing platform for Cumulus1
- More Web APIs with Actix than I can remember
- A cryptocurrency trading bot
- An efficient immediate-mode GUI library that used NanoVG (a vector graphics library written in C) as a backend

Python is my current go-to for most ad-hoc projects. I use it daily for both personal projects and at work. It has never let me down. It's been primarily useful for ML, web development, and automation.

Here's some stuff I made with it:

- Machine learning models in TensorFlow at a high level
- ML models replacing high-level TF with Numpy and raw math where TF wasn't enough
- Countless Web APIs and server applications (usually paired with a React-based front)
- Card generation for learning Mandarin Chinese using Anki SRS
- Advent of Code 2020 challenge (streamed to YouTube, code is on my Github)
- A top-secret serverless application based on AWS SAM
- Rep - my time logging CLI tool for freelance work
- Automation scripts for our Dev OPS processes and ad-hoc needs (work)
- A bunch of internal data analysis tools (work)

A clean and efficient language that reminds us of what life used to be like when we walked around with clubs and lived in caves. Of course, that's a joke. C is one of my favourite languages, it's fast and close to the hardware.

I use it mostly for fun and personal projects:
- An economy simulator based on Perfectly Competitive markets
- A GameBoy emulator
- Advent of Code 2019 challenge (code is on my GitHub)
- Memory allocators, expression parsers, algorithms, benchmarks, stuff like this

My first programming language. I taught it to myself as a kid to make video games, which started off my programming adventure.

Here's some stuff I made with it:
- An electronic school diary system for my former high school
- An application for encrypting and decrypting text using traditional text-based cyphers (Playfair, Vigenere, etc.)
- An Asteroids game to learn text rendering from Signed Distance Fields based on Valve's method used in the Source engine (CS, TF2, L2D, Portal)
- A bunch of work-related GUI applications

JavaScript was the first language I used at work after C++ and PHP and oh boy did it give me a lot of headaches. I implemented Web APIs, backends, frontends, hybrid apps, just about everything.

If you've got a JS headache, I want you to know: that's perfectly normal and there's no need to seek medic... er, that maybe (just maybe) I can help.

A Linux user since kid-years beginning with Ubuntu 8.04 in 2008, I used Linux on and off as a daily driver. Professionally I've mostly been managing servers and software deployments on Linux and occasionally helping with things I just happened to know from using it at home.

I made a simple game in Odin and contributed to the language examples and documentation.
