Senior Software Engineer with 5+ years shipping production systems for clients worldwide: multi-vendor marketplaces, SaaS platforms, REST APIs, mobile apps, and WordPress builds. I've delivered live products for car rental, real estate, vacation rentals, and fintech clients across the UAE, US, and beyond.

I work across the full stack: Python and Node backends, React and TypeScript frontends, AWS cloud, and CI/CD pipelines. Most engagements start with unclear requirements or a messy legacy codebase, and I turn that into a clear plan, shippable increments, and a clean handoff.

I build from scratch or scale existing products, adapt to your stack, own delivery, and hand off maintainable code.
