FAQ
What type of Ruby on Rails projects do you work on?
I work on SaaS platforms, APIs, CRM systems, e-commerce backends, subscription systems, automation tools, and legacy Rails applications. I also handle performance tuning and system improvements for existing projects.
Do you fix bugs in existing applications?
Yes. I can debug and fix issues in production or development environments. I perform root cause analysis to ensure the issue is properly solved, not just patched.
Can you work with legacy Ruby on Rails applications?
Yes. I regularly maintain and upgrade legacy Rails systems, including older versions of Rails, improving stability, performance, and code structure.
Do you handle frontend work as well?
Yes, to a reasonable extent. I can work with JavaScript, jQuery, Bootstrap, ReactJS. For complex UI/UX-heavy frontend work, I can collaborate or integrate with your existing frontend stack.
Can you integrate third-party APIs or services?
Yes. I have experience integrating REST APIs, payment systems like Stripe, AWS services, and tools like OpenAI for AI-powered features.
Do you work on performance optimization?
Yes. I optimize database queries, background jobs, caching strategies, and overall Rails application performance to improve speed and scalability.
Do you deploy applications to production?
Yes. I can help with AWS deployment, Docker setup, CI/CD pipelines (GitHub Actions), and server configuration.
How do you usually work on a project?
First I review the requirements or issue, then I analyze the codebase, identify the root cause or solution, and propose the best approach before implementing changes.
Do you accept small tasks or only large projects?
I accept both. From small bug fixes to full feature development or system improvements.
Should I contact you before ordering?
A: Yes, that is recommended. It helps define the scope clearly and ensures I can deliver the best possible solution within the correct timeframe.
