Proof stack
Practice
I build, refine and take responsibility for the details.
How I work
Flutter is what I do best. I also care about structure, state, design details, copy, and getting the product ready.
01
I check what the screen needs to solve. With Figma I follow it closely. Without it I help shape the flow.
02
Architecture, state, folders, names, and boundaries matter. Version one should not make version two painful.
03
Motion, hierarchy, copy, spacing, loading, and empty states all count. That's where polish shows.
04
Most work is Flutter mobile. When needed I can also handle web, CMS, APIs, dashboards and desktop tools.
Testimonials
Short notes from people I’ve worked with closely, included here as proof of how the work feels from the other side.
Usman stepped in during a last-minute issue before a client meeting and helped steady the product when the team was under pressure. His speed, ownership, and execution made a real difference at exactly the right time.

FAQ
For people deciding whether we should work together.
Sixty years of experience sounds great..
I'd rather see sixty good decisions than sixty years on paper.
Time = where you worked, not how you think. Your work shows that.
I care about the thought process behind the screen: why this flow, why this state, why this detail nobody asked for.
Have you worked in this domain long to know what's good? Have you made mistakes to learn from?
AI speed helps.. it still cannot fake exposure.
Seeing your work and understanding how you think is more important. If your work makes sense without a lot of explanation that's more valuable than a number of years of experience.
Flutter product work. Especially when the idea is clear enough to care about, but not clear enough to build blindly.
New builds, messy flows, product decisions, screens that need thought before code.
I can improve an existing app too. I just like work where there is still room to shape the product properly.
Yes. You work with me directly.
No middle person. No one else is involved.
I do the work. I tell you what I did. I keep the process easy to follow.
If we need to make a decision about something, I will let you know right away.
Yes.
I do not like walking into a project loud. First I understand the current setup: how the code is shaped, how the team works, where the fragile parts are.
Then I start helping.
I work better when people are straightforward with me.
I like it when people tell me what is really going on.
Tell me the real problem. Tell me what cannot break.
Then give me room to work.
I will show progress. If something feels off, I will let you know away.
I do not need the whole "we are a family" speech.
Be fair with me. Take the work seriously. I can work with almost anyone.
Yes. Things change.
That is normal.
Just tell me early.
If the real requirement changed, we change the plan.
If it is just panic in the moment, I do not want to treat that like a new product direction.
I do not like guessing in the middle of a project. Tell me what changed and I will adjust.
You do.
When the project is finished, you keep the code, assets, notes, and anything else created for the work.
I do not hold work hostage.
Flutter is my main ground.
If the product needs it, I can work around it too: TypeScript, Next.js, Swift, APIs, dashboards, small tools.
I will not pretend every stack is my strongest one. Fit matters.
