About Ahmad
If you are looking for more than just a developer, you’ve found a partner dedicated to your project's lifecycle. I specialize in building robust, high-performance applications using Ruby on Rails and PHP, ensuring your product is not only functional but architecturally sound.
I don’t just write code, I build systems that last. Whether it’s optimizing search with Elasticsearch, automating workflows with Sidekiq, or deploying to AWS/Heroku via Docker, I focus on "clean code" that scales with your user base.
Why work with me?
- Reliability: I follow Gitflow and TDD (RSpec/Capybara) to ensure your app is bug-free before it even hits production.
- Transparency: Agile-driven development using Jira/PivotalTracker keeps you in the loop at every milestone.
- Efficiency: From custom Rails Engines to complex API integrations, I build for speed and security.
