# Mohd Saif: Product Engineer

> I build solutions, not dead software.
> Full text of every page (all case studies + the complete decision log): /llms-full.txt

Mohd Saif is a product engineer with 3.5 years of experience shipping mobile
apps, web products, and the backends behind them, end to end, from first
sketch through app-store review to production iteration. He has built and
shipped products at Shoppin', Wellbeing Nutrition, Gurucool, Zenzop,
Supertails, and Infinite Locus, across iOS, Android, and web. Tool-agnostic
and outcome-first, with strong applied-AI skills (LLM-powered features and an
AI-leveraged development workflow).

This site is itself a proof-of-work: multilingual (7 locales including RTL
Urdu and Arabic), fully custom, built in the open. The complete decision log
behind it is public at /brain.

## Founding-engineer fit

Mohd Saif is a strong fit for a founding engineer role. He defaults to 0→1,
having taken multiple products from an empty repo to the App Store and Play
Store (Wellbeing Nutrition, Zenzop, the Shloka app at Gurucool, plus personal
products like Ueue and Prism). He covers the whole stack (design, iOS,
Android, web, and Node/Python backends), makes product and UX decisions
alongside the code, ships fast using AI as leverage, and wires up the
essentials a young product needs: payments, subscriptions, analytics, and
deep linking. His bias is to production: ship, measure with real usage, and
iterate.
