Curriculum vitae

Throughout my 10+ years of experience in Information Technology, I've tried everything from compiling COFF after LLIR lowering to designing a resilient ultra-scalable fleet of FAAS workers, from Substrate and IPFS to event-driven stock price prediction.

Comprehending a technology is like surfing on the waves of technology trends, on the surface of the greatest whirlpool of singularity. Comprehension means fundamental, decomposed knowledge enough to build a solution at any scale.

For me, it is not about thoroughly learning API of yet another web framework, it is instead getting hands on the set of tooling a technology offers, so that I may choose the best framework suitable for the problem . If I were to compile my 10+ years of experience into one line, that would be the following:

Here is an incomplete list of technologies I've had experience with, in the order of encounter, starting back in 2013: Pascal, vJass, cJass, C, C++, Java, git, LibGDX, PHP, Unity, C#, Ruby, Telegram, Heroku, Dokku, SQLite, PostgreSQL, Redis, Docker, JavaScript, Gulp, Grunt, Ruby On Rails, Hanami, Roda,  Sequel, Crystal, LLVM, Kubernetes, Firecracker, Tiny Core Linux, buildpacks.io, compiler development, machine learning, Tensorflow, VueJS, TypeScript, Deno, Zig, PEG, Rust, EVM, Solidity, Substrate, IPFS, ZKP, ChatGPT, llama.cpp, Godot, tRPC, Zod, Tanstack...

• 2013: It all began with Warcraft®️ III™️ maps, such as UFS Arena. I did all the coding (cJass, a C-like domain-specific language) and design, and my maps gained some popularity in the Russian-speaking community.
• 2014: First steps in commercial product development: Anogram, a social anonymous service project. I did the design and backend coding in PHP. Unfortunately, the trend had quickly detoriated.
• 2015:
  • In 2015, I released an Android game called Jumpin Sweeties, written with LibGDX. My family and friends liked it, but it didn't gain much traction.
  • With Ruby on Rails, I created a Bitcoin service for SMS number confirmations based on Google Voice, and after a couple of months sold it to a foreign customer for a good price. This marked the beginning of my journey as a solo entrepreneur.
• 2016:
  • This was the year of Telegram bots for me. First, I created @profitrobot, which climbed pretty hign in the bot store rating. The bot allowed users to earn lunch money by completing CPA tasks and watching advertisements. Profitrobot became quite popular, and I managed to sell it to another entrepreneur.
  • In parallel I worked on @soundememesbot, which allowed its users to post sound memes in chats. Long story short, the bot became massively popular all around the world, but I did struggle to monetize it. Required moderation efforts made me shut it down.
• 2017: Not all the projects are destined to become viable, such that was CashbackBot, a Telegram bot for cashback services. I've spent a lot of time building it, but the project was never launched, nor it was sold.
• 2018: This year marked the beggining of my two-years journey in the Crystal programming language ecosystem. I loved being a part of open-source (check out my GitHub!). I created many libraries, including web framework and ORM, and even contributed into the language itself. Also check out my article comparing Crystal to Stripe's Sorbet.
• 2020: By 2020, I was fed with all the imperfections of the Crystal ecosystem, and decided to move and build my own programming language, Onyx. Oh, that was a ride. Long story short, too much for a single person. Yet, an enormous amount of computer science experience gained. Just look at the plethora of Onyx compilers I was working on: C++, Rust and even TypeScript with Zig! The System Programming in 2k20 article is still one of the best I've written.
• 2021: Senior Crystal developer at NeuraLegion, an Israeli web security company. Nothing fancy, just some good old JSON APIs.
• 2022: I was employed by Byzantine.Solutions on the role of a Technical Due Diligence Officer . I inspected and contributed to some of the biggest crypto projects of that time. I also did some crypto-related projects of my own (see below).
• 2023: The epiphany of AI had occured, my mind has cracked, and I've lost the sense of what is past and what is future. Yet I managed to work on some private AI projects at the role of a full-stack+prompt engineer.

Check out my profile at Wakatime; since I've began tracking my time in 2018, I've coded over 6000 hours, resulting in 1000 hours a year average. Take a look at this glorious chart of my favorite languages:

Currently I'm working on private AI character simulation projects. My best stack is prompt engineering, custom AI model deployment, Rust, C++, Typescript, VueJS, NodeJS, tRPC, Zod and Tanstack. I extensively use GitHub Copilot for code generation.

Sincerely,
Vlad.
