An engineer
who ships.
I'm Uzair Hassan (@syeduzairdev). I build SaaS platforms, cross-platform mobile apps, and custom AI agents & chatbots — and advise teams on the architecture decisions that come before the build. One person, full accountability, no handoffs.

The short version
Product, platform, and AI —
Product, platform, and AI —
shipped by the same pair of hands.
Multi-tenant platforms in production
Subscriptions, billing, role-based access, and real-time dashboards running for clients across the US, UK, and Middle East.
AI agents that do real work
RAG chatbots and autonomous agents built on GPT-4o and LangChain — handling 500+ queries a day inside live products, not demos.
What I do
Five ways in.
Five ways in.
Four to build, one to think.
Four build services and one advisory practice. Built deep rather than wide — which is why I can quote a timeline and hold it, and say no when I'm the wrong fit. Hover a service to see the exact stack I'd reach for.

Advisory
Consulting.
Consulting.
For the decisions before the build.
Sometimes you don't need another pair of hands — you need someone to tell you whether the plan holds. I take a small number of advisory engagements alongside build work, and I'll say no if I'm not the right person for it.
01
Architecture & code review
A structured read of your codebase and architecture, ending in a written report: what's solid, what quietly breaks at ten times the load, and what to fix first. Written for engineers, with a summary your non-technical founders can act on.
02
AI strategy & feasibility
What is genuinely worth building with LLMs inside your product, what looks great in a demo and collapses in production, and what it will actually cost to run each month. I build this category daily, so the answer isn't guesswork.
03
Technical due diligence
For founders or investors assessing a codebase before an acquisition, a raise, or a handover from a previous team. An honest picture of what you're inheriting, including the parts nobody volunteers.
04
Fractional technical lead
An ongoing retainer for teams without a senior engineer in the room: sprint planning, architecture calls, code review, and help hiring the person who eventually replaces me.
Discovery
Free · 30 min
A call to work out whether advisory is even the right shape for your problem.
Single session
90 minutes
One decision, worked through properly, with written notes afterwards.
Review & report
1–2 weeks
Deep read of the codebase and architecture, delivered as a written document.

The story
I care about the thing working
I care about the thing working
long after I've been paid.
I'm Uzair Hassan. Over the past five years I've shipped more than forty products across SaaS, healthcare, e-commerce, AI, and mobile — always as the single point of ownership, from the first spec conversation to the production deploy.
My core focus is SaaS platforms built with React and Next.js. But I'm equally at home shipping cross-platform apps in Flutter, or architecting AI systems on OpenAI, LangChain, and vector databases — the three overlap more every year, and being fluent in all of them is what lets me build the whole thing rather than a slice.
When you hire me you get direct access to the person actually writing the code — not a junior handed your brief after a sales call. I'd rather tell you a feature isn't worth building than bill you for it.
Currently
Two things have
Two things have
my attention right now.
One is a product with real users and a real design bar. The other is the studio I built so I could take on more than one contract at a time.

Kalorist
AI nutrition tracking · screens from the live product, shared with thanks
Kalorist
Kalorist turns a plain sentence — “two eggs and toast” — into tracked macros. I work across the product: the KalScore that grades your day, the AI food-logging pipeline behind Type or Snap, and the dashboard people open before they're properly awake.
It's the part of my week that keeps me honest. Consumer software has no hiding place — users notice a regression the same morning you ship it.
Zypiq Labs
Zypiq Labs is the studio I started and run. It's where client SaaS builds, AI agent work, and my own product experiments live under one roof — with the process, tooling, and standards shared across all of them.
Founding it changed the work: I scope, price, and stand behind whole engagements now, rather than picking up whatever piece someone else already specced.
Why work with me
One developer.
One developer.
No layers in between.
Solo ownership, full accountability
One developer owns the entire codebase. No handoffs, no "that was someone else's work" — accountable for every line from day one to production.
Ship fast, ship right
I've solved the same problems dozens of times. Reusable modules and settled architecture patterns mean faster delivery without the shortcuts.
Deep, not wide
SaaS, mobile, and AI agents. Three focus areas means real expertise instead of answers I looked up an hour before our call.
Honest, direct communication
I'll tell you what's realistic, what's risky, and what I'd do with my own money. No over-promising to win the project.
Security & clean architecture
SOLID principles, proper auth, and careful data handling are the baseline on every project — not an upsell.
Remote-first, genuinely responsive
Async across timezones by default. Reachable on Slack, WhatsApp, or email — you won't be left wondering where things stand.
How I work
From idea to launch.
From idea to launch.
Six steps, no ceremony.
01
Discovery call
We talk through the idea, the goal, and the constraints. I ask the questions that surface the real requirements — usually the ones nobody wrote down.
02
Scope & proposal
A written scope with a stack recommendation, timeline, and fixed price. No vague estimates that quietly double later.
03
Design & architecture
Database schema, API structure, and UI wireframes before a line of feature code. We agree on the blueprint first.
04
Development sprints
Weekly sprints with a Loom walkthrough at the end of each one. You see real progress every week, not a silent month.
05
Testing & QA
Unit and integration tests before every delivery, plus a final UAT walkthrough together before anything goes live.
06
Launch & handover
I handle deployment and CI/CD, then hand over full documentation and credentials. Thirty days of post-launch support included.

Alkhidmat verified donation screenshots by hand — Zakat and Sadqa proofs checked against bank statements, logged, and pushed to dashboards by a team of eight, at roughly Rs. 5 lakh a month in salaries.
We replaced the loop with a multi-agent workflow. A donor sends payment proof to the WhatsApp bot; the agent checks it against live bank statements and flags fakes on the spot; verified transactions land in the database, the admin dashboard, and a local Excel sheet; then a personalised WhatsApp reply goes out asking what the donation is for. Tooling costs Rs. 50k — the rest is saving.

Questions
I get asked first.
Small projects take 2–3 weeks. A full SaaS platform or AI agent system typically runs 6–12 weeks. You'll get a precise timeline in the proposal — and I hold it.
Fixed-price for clearly scoped projects, so you know exactly what you'll pay. For ongoing work I offer monthly retainers. I'll recommend whichever genuinely fits your situation.
Every project includes 30 days of free post-launch support — bug fixes, deployment issues, and minor tweaks at no extra charge.
You do, entirely. Full IP ownership transfers on final payment — complete source code, documentation, and credentials. No strings.
Regularly. I work alongside in-house teams, run code reviews, and do architecture consulting. I'll start with a technical audit to find where I add the most value.
Async-first: daily Slack or WhatsApp updates, a weekly Loom progress walkthrough, and a shared board so you always know exactly where things stand.
