Senior full-stack developer who builds ERP, web apps, and responsive UI with modern JS.
EgyptWhat I'm looking for
I’m a Senior Full Stack Developer with a long programming journey that started in 1988, and I’ve built extensive experience in web and software development using many technologies. Over more than 15 years, I’ve delivered many remote “software and web development projects” via Upwork (previously elance + odesk), and I genuinely enjoy learning new skills to fuel my passion for coding and computers.
My work has often centered on practical, high-impact systems—especially ERP and inventory workflows, plus server utilities, barcode scanning, touch UI, analysis reports with charting, and client/server n-tier architecture. I also develop modern responsive front ends (JavaScript/React/TypeScript), REST API backends (Node/express), and database-driven solutions across multiple SQL systems, while staying hands-on with automation (Selenium, automation apps) and Windows application development (Delphi/Object Pascal, C#).
