WHAT I DO
From first decision.
To shipped product.
Make it AI-first.
AI should do more than generate text. I build it into real workflows to find the right context, automate repetitive work, and track quality as it improves.
- AI agents
- Retrieval & extraction
- Evaluation
Rescue what you have.
I untangle products that have become hard to change, fix what is slowing the team down, and make shipping feel straightforward again.
- Technical audits
- Refactoring
- Performance
SELECTED WORK

ABOUT
Beyond
the code.
01 HOW I WORK
I don't just hand over code and walk away.
Taking a new idea and making it real is stressful. You’re putting your time and reputation on the line. You need someone in your corner who cares about the outcome as much as you do.
I figure out what your customers need, build the foundation and stay close after launch. Running my own products has made me a better engineer for yours.
REVIEWS
What it’s like
to work with me.
A few honest words from the people I’ve built products with.
Throughout our collaboration, Zain consistently acted as a strategic partner, not just an engineer. He regularly shared valuable ideas, challenged assumptions, and suggested practical improvements that made our products stronger and more user-focused. His ability to combine technical expertise with product thinking is rare.

Zain worked with me, and from the start, I could tell he was different. He’s a solid full-stack developer, but what really stands out is how fast and reliable he is. He doesn’t just wait for instructions, he thinks ahead and gets things done.
Huzaifa ZahoorFounder of Meyka AI · Software & data engineer
I had the pleasure of working with Zain for almost two years. As a software engineer and full stack developer on my team, Zain was incredibly talented and smart. Even with only a few months of experience when he started, he quickly amazed me with his skills and hard work.

QUESTIONS
Before the
first call.
A little context before we build together.
Do you work solo or alongside my team?
Both. I built and still run Protawk largely on my own, from product decisions and the data model through launch and billing. I have also worked inside teams, adapting to their communication, review and release rhythms while contributing beyond my own area. I am comfortable owning a product end to end or working closely with a team to make the whole thing better.
Can you add AI to a product I already run?
Yes. The best AI features feel like a natural part of a product, not a separate gadget. I can help find the right use case, connect it to your own data and place it where people already work. We start with something useful, see how it helps, and improve it from there.
How long does a build take?
It depends on scope, which is what the first call is for. What I commit to is rhythm rather than a single distant date: a written plan before code, then working software on a staging URL every week so you can judge progress yourself.
What does it cost?
Each project is scoped and quoted after the first call, once we both know what actually has to exist. Send me a short description of what you are building and I will tell you what it would take.
