Salim Hussaini
Fullstack Software Engineer
Senior Fullstack Engineer specializing in high-performance web applications, with a track record of shipping production systems across e-commerce, civic tech, and AI/ML domains.
About
Over the last six years, I have engineered software for everything from international e-commerce platforms to national tech agencies, working across React, Next.js, Node.js, and PostgreSQL to ship everything from ML-powered diagnostic tools to full-scale e-commerce platforms. Today, I combine that engineering depth with cybersecurity research in Zero Trust microservice architecture to build systems that are as secure as they are scalable.
Most recently, as a Senior Frontend Developer at NEXT BASKET, I led performance work on high-volume order pages handling 10,000+ records, architected a shared AI chatbot package across two platforms, and established frontend testing standards across the Next.js codebase. I am always exploring the edges of modern web tech, which is why I chose to build this portfolio using Astro.
