Hey DEV community! This is my first time posting here.
Over the last 10 months, I have been locked in my room building a fully automated digital asset index fund platform called Wealtii. I built the entire thing completely alone.
It is a live, production grade financial system that lets anyone invest in diversified crypto index funds from $10, with full fiat onramps and multi signature custody.
To give you an idea of the scale, the codebase just crossed 315,000 lines of code across frontend, backend, smart contract integrations, and infrastructure. It handles real money, executes autonomous trades on decentralized exchanges, and runs 24/7.
I wanted to share exactly how I architected this system as a 22 year old solo developer, the stack I used, and the absolute hardest engineering challenges I faced along the way.
