Privacy-first software. Built to ship.

Hi, I'm Hassan.

I build products end-to-end, from problem definition to a working, reliable system people can use. I care about speed, simplicity, and trust—especially when the workflow touches sensitive or regulated contexts.

Right now, I'm building OneClickReceipts, a fast, privacy-first receipt workflow for clinicians.

What I'm Building

OneClickReceipts

A practical tool for clinicians who need receipts to be effortless and low-risk.

What we optimize for

  • Fast, hassle-free workflow: fewer steps, less friction, less cognitive load.
  • Privacy by design: collect the minimum, avoid unnecessary fields, reduce exposure.
  • Separation of concerns: admin workflows (like receipts) stay clearly separate from anything clinical.
  • Professional output: clean receipts, consistent formatting, predictable results.
  • Built with real-world input: designed alongside a practising clinician who deals with these pain points firsthand.

How I Build

I like building products that feel calm and obvious to use. My default approach is:

→
Start with the workflow, not the feature list.

The goal is fewer clicks and fewer mistakes.

→
Minimize data collection.

If we don't need it, we don't store it.

→
Design for trust.

Clear boundaries, clear control, and predictable behavior.

→
Ship in tight loops.

Release small improvements, learn fast, and keep quality high.

→
Keep the system understandable.

Simple architecture beats clever complexity.
