John Nessime — Data & Cloud Solutions Architect

// About

Building systems where
cloud meets data

I am a Data & Cloud Solutions Architect specialising in AWS infrastructure, data engineering, and business intelligence. With 8+ years of freelance experience, I design and build scalable systems — from multi-account AWS architectures and data lake pipelines to Power BI dashboards and production observability stacks.

I approach every engagement as both an architect and an engineer: I don't just design systems, I build and operate them. My work spans cloud infrastructure, full-stack web platforms, structured log analytics, and automated security frameworks.

Based in Cairo, Egypt, I work with clients across the MENA region and globally — with native Arabic, full professional French, and strong English fluency giving me a natural edge in multilingual engagements.
