Being self-taught, my imagination is limitless.
At first, it was for fun & games.
Now, several years later, it's for serious blockchain stuff.
I have experience in multiple languages and frameworks:
Python (natively / FastAPI)
HTML + CSS + JS (mostly natively)
Vyper / Solidity (tokens / bridges / faucets)
name something else - I may have done it, or at least heard about it.
Here are some services and tools that were created by me from scratch. Various backend combinations were used, like smart contracts for EVM or backend FastAPI applications for Cosmos.
Lots of other great stuff (block explorers, chain-specific services) are already in the works!
