About Emad

I'm a backend software engineer with 8+ years of experience building fintech systems — trading platforms, payment infrastructure, and distributed backends where correctness under real financial load is non-negotiable.

My core stack is Python and Node.js, with deep expertise in PostgreSQL, microservices, and clean architecture. I've built and led engineering on algorithmic trading systems, CRM platforms for forex brokerages, NFT marketplaces, and trade-compliance platforms — handling everything from architecture design through production delivery.

What I bring to your project:
• Fintech-grade reliability: idempotency, concurrency control, and fault-tolerant systems
• Full ownership from architecture to deployment
• Experience leading technical teams and bridging product strategy with engineering execution
• Background spanning forex/crypto trading, payment systems, and distributed backends

I work best on projects that require serious backend thinking — where the system needs to handle money correctly, every time. Open to backend, full-stack, and technical lead engagements, remote or on-site.
