About Me

I'm a software engineer based in Dubai, specializing in Ruby on Rails development with a focus on performance optimization and user experience.

What I Do

I work with Ruby on Rails applications, helping companies optimize their systems for better performance and user experience. Most of my time is spent on database optimization, improving API response times, and building frontend interfaces with Vue.js and Hotwire.

Performance engineering is where I spend most of my focus - making applications faster through query optimization, caching strategies, and infrastructure improvements. I also work on the frontend, building interfaces that are responsive and easy to use.

Background

I've been working with Rails for over 15 years, building applications across different industries including SaaS platforms, e-commerce systems, financial applications, and healthcare software.

Currently based in Dubai and working remotely with clients around the world. I keep up with the Rails ecosystem - Rails 8, Hotwire, and modern deployment practices.
