Professional Summary

Software engineer with 10+ years of experience and founder of Khwarizm Tech Group. I own products end to end: architecture, frontend, backend, data, payments and deployment, then lead their growth and operation after launch.

I have built a cross-platform accounting system with an e-invoicing engine covering nine Arab countries, a learning platform with verifiable certificates and offline mode, a multi-merchant payment gateway, an AI motion-video studio, and a Wi-Fi network management suite.

I work with a disciplined, AI-augmented engineering process: feature branches and pull requests, automated tests, continuous integration, and production error monitoring.

Experience

Founder & CEO · Khwarizm Tech Group
Present
- Founded a tech group spanning NETco, ReelsGo and SADEEM Studios plus the Khwarizm Academy, Khwarizm Pay and Monsati platforms; I set its technical and product direction.
- Personally designed and built the architecture of every product in the group, from Flutter apps to Next.js platforms and Python services.
- Built the group's shared infrastructure: a unified payment gateway, a central admin hub aggregating live KPIs from four products, and automated publishing to Facebook and X.
- Established the engineering workflow: pull requests for every change, Vitest and Playwright in CI, Sentry error monitoring, and continuous deployment to Firebase App Hosting.

How I work: AI-augmented engineering

I use Claude and Claude Code as a daily engineering partner, with the discipline of a professional software team:

• Every change lives on its own branch and goes through a reviewed pull request before production.
• Automated tests and CI block any merge that would break the product.
• Decisions and official sources are documented in the repository, such as a per-country e-invoicing regulations reference.
• Faster delivery without trading off quality: complete products built and launched within weeks.
