About Youssef

Senior Software Architect & Technical Advisor (ENSIMAG) Specialized in High-Performance Financial Systems & Risk Engines

With 15+ years of experience across top-tier investment banks and energy trading firms, I architect and deliver scalable, distributed solutions for complex Front-to-Back environments. My expertise lies in modernizing legacy architectures, optimizing grid computing performance, and designing robust frameworks for pricing, VaR, and P&L computation.

Core Value Proposition:

Technical Authority: Deep mastery of the Microsoft .NET ecosystem, distributed systems, and modern data architectures (SQL/PostgreSQL).

Domain Expertise: Extensive experience designing engines for Market Risk, Greeks calculation, and Pricing.

Strategic Delivery: Proven ability to lead migrations, bridge legacy and modern stacks, and automate operational workflows for maximum efficiency.

I am seeking freelance opportunities to guide development teams, accelerate delivery, and architect future-proof platforms within the financial sector.
