The timeline
9 chapters, in order.
01 · Pre-developer · 20192019 zero lines of code
I didn’t know how to code.
Freshman year of computer science with no coding background at all. What I had was gaming, curiosity and a lot of passion. That turned out to be enough to start.
02 · BSCS 1st semester · 20197 sleepless nights, one Ludo game
The first real project.
A Ludo game in C, console-based. Seven sleepless nights and zero idea what I was doing. It worked.
- C
LabLudo, in C
03 · PHP dev · 2020PHP what can I build?
Then something clicked.
The question changed from “what can I learn?” to “what can I build?”. So I built clones and small apps, just for fun.
- An OG Facebook Messenger clone
- Tic Tac Toe
- A Yahoo scraper, and Celina, a little assistant (named after Celine <3)
- The MAJU Event Planners website (my teacher said I stole it XD)
- An Instagram clone
- A Wattpad-like book store
- A CS:GO skins marketplace
- And, the same spring, the President’s Honor Roll at MAJU
- PHP
- MySQL
- JavaScript
04 · 20218 admin modules, auto-generated
I hated repetition, so I automated it.
Instead of doing the same work twice, I wrote tools that did it for me.
- An HTML-to-JSX converter
- React Builder and Atom Builder
- Python scripts that generated the whole admin for the DA SKBZ College system: Shifts, Students, Departments, Classes, Sections, Subjects, Slots and Visitors
- C
- PHP
- Python
- JavaScript
05 · Fiverr · Apr 2021$70 first order, + a $34.70 tip
The first earnings.
My first Fiverr order paid $70, plus a $34.70 tip. The client wrote that I dominate my work and find solutions quickly. All of it ran on a PC built with my dad’s investment, modifying a commercial PHP library. 100+ orders came after that, and Level 2 Seller.
06 · Full-stack dev · 2022–23x2 monitors, one trading desk
Complex systems.
I moved from websites to enterprise-level, real-time apps.
- Text-to-video without AI: human speech plus related backgrounds, end to end
- A virtual wardrobe that matches outfits automatically, with no repeats (it later grew into Mirror Me, a Flutter + Gemini try-on app)
- A real-time commodity trading system: dual monitors, charts, order books, a matching engine and 38+ endpoints. It was hard, though.

07 · AI & ML · 2023AI and I fell for data
Then I met AI.
I fell in love with data and machine learning, and the projects changed shape.
- First data project: a COVID-19 analysis of 12-13-2020.csv, also my first repo on GitHub
- First AI project: Karachi Zameen Finder, which scraped the whole of Zameen.pk and predicts plot and flat prices
- Photo → Mood → Music: emotion detection that builds a Spotify playlist
- Final-year project: ChatDoc, an NLP + face recognition doctor’s assistant, funded by Ignite

08 · 2023–26MS Artificial Intelligence
And I kept building.
Community, a degree, real production systems, and then a second degree. AI became where I settled.
- Web Dev Lead, Google Developer Student Club @ MAJU (2022–23)
- Seminars, competitions, Jinnah League (Tekken / FIFA) and freelancing awareness sessions
- Graduated from Mohammad Ali Jinnah University (2023), then kept mentoring juniors
- Fiverr Level 2 Seller: 100+ orders, 80+ five-star reviews
- Open-sourced Hitlimit (5.5M+ rate-limit checks per second on Bun) and bunWay (an Express-compatible framework for Bun) under JointOps, my open-source org
- Started an MS in Artificial Intelligence at Bahria University (2025) and built Ask Bhittai, a RAG system over Sindhi Sufi poetry
- Co-authored a trajectory-prediction paper for autonomous driving, now under review

- Karachi AI Meetup #24, and a lot more seminars
09 · 2026Now Full Stack AI Engineer
I’m Rehan. Full Stack AI Engineer. Researcher.
I observe problems, think of a solution and code it. Now that means document AI, reliable LLM systems and a thesis on teaching phones to say “it’s not here” for blind and low-vision users, and I build it all in public: face + code. No fancy gear, just a phone, CapCut and OBS.
