About

I’m Abdusaid, a full-stack Ruby on Rails developer with 4+ years of experience building scalable applications in SaaS, Fintech, e-commerce, and Gaming. My expertise lies in designing robust APIs, architecting clean database schemas, and developing features that are both user-friendly and performance-driven.

What makes me different is my ability to bridge traditional Rails development with modern AI/ML capabilities using Python. I don’t just deliver features - I design systems that combine business logic, automation, and intelligent decision-making.
