AAaqib SheikhTechnical Product Partner
Available for fintech & Web3 product engagements

I ship the parts of your product that can't afford to break.

Senior full-stack engineer for fintech and Web3 founders. Payments, KYC, wallets, smart contracts, and the architecture that holds them together — taken from messy scope to production.

For products where a wrong technical decision costs real money — regulated workflows, on-chain logic, and money-moving systems that have to work the first time.

Where founders get stuck

Your product doesn't need more code first. It needs connected product thinking.

Most products don't fail because the frontend is missing one more screen. They fail because product, business logic, architecture, integrations, and execution are disconnected.

01

You have an idea, but not a clear product structure.

I help turn loose founder thinking into flows, scope, priorities, and a buildable system.

02

You have Figma screens, but no real backend logic.

I connect the UI with roles, permissions, data models, APIs, states, and edge cases.

03

Your MVP works, but every new feature creates mess.

I stabilize the architecture so the product can keep moving without breaking.

04

Your product depends on APIs, payments, wallets, AI, or compliance.

I handle the technical layers that need careful thinking, reliability, and trust.

05

Your team can build screens, but nobody owns the full system.

I bring full-stack ownership across product, frontend, backend, integrations, and deployment.

06

Your product is live, but hard to maintain or scale.

I audit, simplify, refactor, and create a path toward a healthier system.

Value

Three things I'm hired to get right.

Anyone can write code. The hard part is reducing product risk, making the right technical call early, and shipping a system that survives real users and real money.

01

Product Clarity

I turn founder goals into product flows, user journeys, feature priorities, technical requirements, and realistic build roadmaps.

02

System Architecture

I design the structure behind the product — frontend, backend, database, roles, permissions, APIs, integrations, wallets, payments, AI workflows, and infrastructure.

03

Execution Ownership

I build across the stack and move the product from uncertainty to production without creating unnecessary technical debt.

Ways to work together

Process

How I move a product from uncertainty to production.

01

Diagnose the business problem

I first understand what the product is supposed to achieve, who it serves, what already exists, and where the risk is.

02

Map users, roles, workflows, and edge cases

I turn unclear requirements into user flows, system states, permissions, data needs, and technical constraints.

03

Design product and system architecture

I define how frontend, backend, database, APIs, integrations, wallets, payments, AI workflows, and infrastructure connect.

04

Build in focused milestones

I break execution into practical milestones so the product moves forward without unnecessary complexity.

05

Stabilize, launch, and improve

I focus on production readiness, performance, reliability, usability, and maintainability after launch.

Technical depth

Product thinking backed by full-stack depth.

Fit

Who I work best with.

Best fit
  • Founders building fintech, Web3, or money-moving products
  • Startups moving from idea or prototype to a serious MVP
  • CTOs or teams needing senior full-stack ownership
  • Products with payments, KYC, wallets, smart contracts, or complex workflows
  • Founders who value the right technical call early, not just fast output
  • Teams that need one person across product, frontend, backend, and infra
Not the right fit
  • Cheap landing pages
  • Small patch tickets
  • Pixel-only frontend tasks
  • Projects with no clear decision-maker
  • Work where speed means ignoring product / system risk
  • Clients looking only for the lowest hourly rate
About

The partner you bring in when money is on the line.

I started as a developer building business applications and backend systems. Over 8+ years I've shipped regulated lending flows, multi-chain staking, KYC pipelines, escrow and wallet systems, and on-chain ownership — the work where a wrong decision costs real money, not just a re-deploy.

That's where I'm most useful: founders, CTOs, and product teams building fintech and Web3 products that have to be trustworthy from day one. I take unclear scope and turn it into a system — owning product logic, architecture, and execution end to end so nothing falls between roles.

I'm not the cheapest option, and I'm not trying to be. I'm the person you bring in when the product can't afford to break and you need it built right the first time.

FAQ

The questions founders ask before reaching out.

A short intro call. You tell me what you're building and where it feels risky; I tell you which engagement fits — or point you elsewhere if I'm not the right person. No pressure, and you leave with a clear next step either way.

The numbers on each engagement are starting points. After the intro call I scope the actual work and send a fixed price, so there are no surprise hourly bills. You always know the number before anything starts.

I take full ownership across product, frontend, backend, integrations, and deployment, so nothing falls between roles. For larger builds I can bring in trusted engineers under my direction — you still deal with one accountable person.

Yes. The Rescue & Scale Audit exists for exactly that — inherited code, an unstable MVP, or a team that needs senior technical direction. I diagnose first and give you an honest path before touching anything.

I work async-first with clear written updates and scheduled check-ins, and I overlap with US and European hours for live calls. You'll always know what's in progress and what's next.

You do — fully. Everything I build is yours, handed over with documentation and a clean deployment so your team can run it without me.

Let's talk

Building something that can't break?

Tell me what you're building, what stage it's at, and where it feels risky. I'll point you to the right next step — architecture sprint, MVP build, or rescue audit — even if that means telling you I'm not the right fit.

The call is free, and you'll leave with a clear next step — even if we don't work together.

Best for fintech, Web3, and money-moving products — payments, KYC, wallets, smart contracts, and the production architecture behind them.
