(04) how i work
close to the problem, all the way to production.
- 01
Start with the problem
I'd rather understand the user and the decision behind a feature than receive a finished spec. Better questions make simpler products.
- 02
Simplify the core
Find the one experience that matters, make it feel effortless, and only then add more around it.
- 03
Own the trade-offs
Speed, cost and quality pull in different directions. I choose deliberately, explain why, and carry the work through to production.
- 04
AI speeds the work, not the judgment
AI-assisted tools help me explore and iterate faster. Product decisions, architecture and final quality stay my responsibility.
(05) services

Working with Usama on Aatish Media’s website was a great experience. He was professional, helpful, and guided me through everything I needed to set up on my end.
His eye for design really stood out, from the layout and alignment to knowing exactly what belonged where.
He put real thought into both the design and optimization, and I couldn’t be happier with how it turned out.
(07) about
i'm an ai product engineer who likes working close to the problem, not only receiving finished specifications. my strongest work sits between product, design and engineering.
building products independently has taught me how to shape ambiguous ideas, simplify the core experience, make technical trade-offs and carry the work through to production.
ai-assisted coding and design tools are part of my everyday workflow. i use them to explore and iterate faster while remaining responsible for the product decisions, architecture and final quality.

questions, answered.
-
Product engineering roles and independent projects: mobile apps, websites, SaaS products and AI features. I'm most useful from the early, fuzzy stage through to a shipped product.
-
Yes, for the right product team. I'm open to full-time product engineering roles as well as independent projects. Send a note to hello@usamakashif.me with what you're building.
-
Yes. I take a product from the idea through flows and UI to production code, so nothing gets lost in a hand-off between design and engineering.
-
AI-assisted tools help me explore and iterate faster, and I build LLM features into products. Product decisions, architecture and final quality stay my responsibility.
-
React Native and Expo for mobile; React, Next.js and TypeScript for web; Supabase for backends and PostHog for analytics, with LLM integrations where they earn their place.

Email hello@usamakashif.me with a short note on what you're building and where you're stuck. I'll reply with questions and how I'd approach it.
