OH HEY, A HUMAN.

Yeah, you're not seeing that.
Just kidding 😂

01 / Receipts
I mean, my GitHub contribution graph isn't one of those nerdy 3,000-contribution green forests you see online.
I code with Codex.

No streaks were harmed in the making of this portfolio.
They told me tech guys bag bitches.
They lied.One good thing I've learned since becoming a developer is that apparently I'm multilingual.
I speak
01
TypeScript
fluent
02
JavaScript
it's complicated

SQL
conversational
04
Python
enough to get myself in trouble

Thanks. My mum can see my career now.
ALRIGHT, ENOUGH OF THE JOKES.
I'm serious now.
02 / Origin story
Faruq's story
I'm Faruq Etamesor, a developer and builder with a particular obsession with sports, technology and entertainment.
I've always wanted to be part of the sports and entertainment world in some way. I didn't necessarily know what that would look like — I just knew I wanted to build something that belonged there.
So I started building Masterspred.
What began as an idea turned into a real sports prediction community — and somewhere along the way, I found myself learning far more than just how to build a website.
I work across the frontend, backend, databases, infrastructure and product itself.
In other words:
I like turning ideas into things people can actually use.
03 / Under the hood
THE NERDY STUFF.

THE THING THAT GOT OUT OF HAND.
MASTERSPRED
A sports prediction community I somehow decided would be reasonable to build from scratch.

Me: This shouldn't be too difficult.
Also me: learning database concurrency, payment flows, CDN caching, load testing and why race conditions exist.

Not because I was worried.
Because I was professionally curious.

WHEN I'M NOT
STARING AT A TERMINAL
Most of my interests somehow lead back to sports, entertainment or technology.
Sometimes all three.
Which is probably how Masterspred happened in the first place.
