Rails Performance Tuning, Security and Reliability Audit

Don't wait for an actual incident to improve your app's security. Frustrated clients will not tell you that your website is slow but click away to the competition.

I'm available to conduct a performance tuning and security audit of your Rails app. You can now improve the fundamentals of your project, without compromising on your roadmap and features development speed.

I offer a condensed set of security and performance-related best practices that I've already applied in numerous client projects. Sometimes it took our team months of work or an actual security incident to realize that we needed this particular solution in place.

The final outcome of my audit is not only the report of what you should fix in your app. I can submit the PRs with improvements to your Rails app repo and apply infrastructure fixes. Additionally, I'll guide you through my process of identifying, debugging, and fixing bottlenecks. As a result, you'll be able to apply similar fixes yourself when new issues pop up.
