About Us

We build software.
And we build the people who build it.

Study E-Hub is a software house and mentorship academy based in Sahiwal, Pakistan. We deliver client projects — and train engineers, designers, and developers on them. We also publish a free Computer Science notes library for 10th Class, 1st Year, and 2nd Year, and we only list what we actually have.

Our Story

Started with one laptop
and a simple belief.

Study E-Hub didn't start as a business plan. It started as a frustration.

Our founder kept seeing the same thing — bright students with real potential, graduating with degrees that taught them theory but not craft. They knew what a database was. They just couldn't build one. They could define an algorithm. They'd never shipped it.

So we built the opposite. A studio where real client work is the curriculum. Where students don't practice on dummy tasks — they ship code that real businesses depend on. Where the feedback loop is a paying customer, not a graded rubric.

"Teach on real projects. Ship real work. Grow real careers. Everything else is noise."

Six years later, that philosophy has produced 30+ trained professionals and 15+ long-term business clients. Along the way we started a free Computer Science notes library for 10th Class, 1st Year, and 2nd Year. We will add more subjects only when the files are ready.

Mahmood Khan

CEO & Manager · MS Cybersecurity MS CYBER

Mahmood leads Study E-Hub with a rare combination — deep technical expertise in cybersecurity and a genuine obsession with teaching.

With a Master of Science in Cybersecurity, he's architected security protocols for banking clients, led penetration testing engagements for enterprise systems, and built the ISO-aligned internal practices that keep every project we ship above standard.

But ask him what he's proudest of, and he won't mention a project. He'll mention the student who joined with no coding experience and now works at a US startup. Or the one who went from a beginner to a certified ethical hacker in eighteen months. That's the work he cares about.

What We Stand For

Six principles we won't compromise on.

These aren't values on a wall. They're the actual rules we use to make decisions — every project, every student, every day.

— 01

Real work, not simulations.

Our students don't build to-do apps for practice. They ship features that real users depend on. That's the only way to actually learn.

— 02

Your data is sacred.

Every team member and student signs an NDA. Every project is encrypted. We have never had a breach and we intend to keep that perfect record.

— 03

We tell you the truth.

If a deadline won't work, we say so. If a feature isn't worth building, we say so. Honest estimates beat comfortable lies every single time.

— 04

We answer our emails.

No ghosting. No "we'll get back to you" that never happens. Real replies within a business day, from real people who actually read your message.

— 05

We teach, not just deliver.

Every project is a chance to level up a student. We'd rather ship a slightly slower solution that leaves someone more skilled than a fast one that teaches nothing.

— 06

We stick around after launch.

Six months of free maintenance on every project. Because shipping is the start of the relationship, not the end.

"We're not the biggest software house. We're not trying to be. We're trying to be the one that actually cares about what we ship and who we train."

— Mahmood Khan, Founder
