Two years ago I thought the hard part would be writing trading algorithms.
I was wrong.
The hard part was building software that keeps working when real markets, real APIs, and real users get involved.
I built IMALI as a solo developer while driving Uber to fund development. There were plenty of nights where I'd spend hours chasing bugs after finishing a shift.
Along the way I ran more than 75,000 paper trades, tested with my own capital, and rebuilt large parts of the platform after watching early users struggle with the interface.
Lessons I learned
- APIs fail more than your code
Exchange APIs change.
WebSockets disconnect.
Rate limits happen at the worst possible time.
You don't build for the happy path—you build for recovery.
- Paper trading is harder than it looks
A believable paper trading experience isn't just fake orders.
It has to simulate execution, update positions correctly, calculate P&L, and give users confidence before they ever risk real money.
That became one of the biggest parts of the project.
- Risk management matters more than entries
Finding trade opportunities is interesting.
Managing risk is what keeps software usable.
Position sizing, stop-losses, trailing stops, confidence thresholds, and market filters became more important than trying to predict every market move.
- User experience is part of the algorithm
I rebuilt the dashboard multiple times.
Not because the trading logic changed—but because users couldn't understand what the bot was doing.
The best algorithm doesn't matter if users don't trust it.
- Shipping beats perfection
The platform is still evolving.
But after two years it reached a point where I was comfortable putting real users on it instead of endlessly adding features.

I'm still learning every week, but this project has made me a far better engineer than I was when I started.
If you're building something ambitious by yourself, keep going.
Sometimes the biggest milestone isn't writing a clever algorithm.
It's building software people are willing to trust.
I'd love feedback from other developers who have built trading systems, fintech products, or software that depends heavily on third-party APIs.
