LinkedIn · Projects · Contact

Hi, I'm Hassan

Software engineer based in Cairo, Egypt, with experience in backend and mobile development and an interest in practical AI tooling. I enjoy turning complex problems into useful systems—and making those systems easier to understand and maintain.

Currently building: Traceweave

Engineering knowledge you can trace.

Traceweave connects engineering documentation, architecture, and code changes, with a focus on explicit provenance and human-approved AI contributions.

  • Separate human-curated facts, code-verified evidence, and AI inference.
  • Connect architecture knowledge to source code and change analysis.
  • Let agents propose improvements while people control publication.

Traceweave is in development; its repository is currently private.

Areas of focus

Area Technologies
Backend engineering Java, Kotlin, Spring, NestJS
Mobile development Kotlin, Android
Web and developer tools TypeScript, React, Next.js, MCP
Data and infrastructure PostgreSQL, Redis, Docker
Exploration Python, AI-assisted workflows, problem solving

Selected public work

How I approach engineering

Readable code. Clear boundaries. Evidence over assumptions. Small, reviewable changes. And documentation that helps the next person—not just the person who wrote it.
