Wafia Mustafa
I'm a Senior Software Engineer - tech lead who believes software should be scalable, maintainable, and designed around business outcomes. My approach combines clean architecture, measurable quality, and practical AI to help teams deliver value faster.
A lead who still writes the code.
I build software that ships, scales, and stays easy to change — for teams that measure outcomes, not output.
I spent the last 8 years growing from senior engineer into technical leadership at KPI Fire — an enterprise SaaS platform — where I owned architecture on Angular and Node.js, coordinated a distributed team across Egypt and India, and answered for system performance KPIs.
Outside full-time work I've delivered 20+ freelance builds on Upwork with 100% on-time delivery — and mentored students at ITI into their first developer roles.
~50% lift via API tuning, Redis caching & frontend work.
Production LLM features on OpenAI & AWS Bedrock.
Distributed team across Egypt & India; juniors leveled up fast.
