Products I've shipped
AI-powered SaaS platforms, web applications and mobile apps — taken from first scope through to production.
SaaS
2025ZygenAI
AI support agents for marketplace sellers
A customer support platform that answers buyer messages automatically using live order data. It reads each message, pulls real tracking and delivery details, and replies in the seller's own voice in under 30 seconds — grounded in verified order records rather than guesswork.

- TypeScript
- Node.js

SaaS
2025Clear Sky Co
Practice analytics for allied health clinics
An advisory platform that shows clinic owners the numbers behind their business. It syncs with Cliniko and turns raw practice data into the three metrics that decide profitability — clinician utilisation, revenue per clinician and margin — so growth decisions stop being guesswork.
- Next.js
- TypeScript
- Node.js

Web
2025ScriptLix
A marketplace for production-ready screenplays
A curated catalog where independent filmmakers read screenplays free online and buy the ones they want to produce. Every purchase delivers the script in PDF, TXT and Fountain, so it drops straight into a writer's existing toolchain.
- Next.js
- TypeScript
- Node.js

AI
2025Support Desk AI
Ask questions about your own documents
A document assistant that answers questions grounded in files you upload. The source document opens beside the chat, so you can read the original and interrogate it at the same time instead of trusting the answer blind.
- Python
- FastAPI
- RAG

SaaS
2025SkillPet
Gamified AI learning platform with subscriptions
A learn-mode SaaS platform that turns AI courses into a habit. Learners get streaks, XP, gems and lives alongside a companion pet that keeps them coming back, while a Pro tier unlocks the full catalog and premium lessons.

Mubashar Nouman
Senior Full Stack Engineer
Over the past four years I've built AI SaaS platforms, web apps and mobile apps end to end — most recently ZygenAI, a support automation product answering marketplace buyer messages from live order data.
You don't need to assemble a team. I cover architecture, AI integrations, APIs, authentication, billing, dashboards and deployment — and I write code your next developer can actually pick up.

How We'll Work Together
A predictable process, so you always know what's happening and what comes next.
- 01
Discovery call
We talk through the problem, your users and your constraints. You leave with a clear view of scope, whether or not we work together.
- 02
Proposal & plan
A written breakdown of deliverables, timeline and cost. Fixed scope up front, so there are no surprise invoices later.
- 03
Build in sprints
Weekly demos of working software. You see progress continuously and can redirect early instead of at the end.
- 04
Launch & handover
Deployment, documentation and a walkthrough of the codebase, plus a support window to settle anything post-launch.
