About Zakaria

Full Stack Engineer with 13+ years building production-grade web platforms
across fintech, energy trading, and high-growth product environments.

I design and deliver end-to-end systems — from Node.js backends and REST/GraphQL
APIs to React frontends and cloud infrastructure (Azure, GCP). I work on systems
where reliability, scalability, and code quality are non-negotiable.

Past environments include tier-1 investment banking (BNP Paribas CIB),
energy trading infrastructure (ENGIE), and B2B travel platforms at scale (Worldia).

I take ownership of technical decisions — not just tickets. I work closely
with product, DevOps, and business stakeholders to ship systems that last.
