Le job board inversé pour les développeurs Rails

My journey into software development started with a deep curiosity about how systems scale and handle complex workflows. Over the last 4 years, I’ve specialized in Ruby on Rails, PostgreSQL, and system optimization, working on high-impact financial platforms. At Vartana, I led the complete revamp of the servicing system, transitioning from invoices to account statements, improving financial tracking, and optimizing execution times by 67%. I also played a key role in migrating our entire system to Kubernetes, reducing deployment time by 83% while ensuring zero downtime. Beyond writing efficient and maintainable code, I excel at troubleshooting critical issues, optimizing SQL queries, and enhancing system performance. One of my proudest achievements was reducing page load times by 90% (20s → 2s), significantly improving the user experience. I’m passionate about scalability, DevOps, and financial systems—I love architecting solutions that not only work but scale seamlessly. Whether it's optimizing background jobs, improving API performance, or automating workflows, I thrive on making systems faster, more efficient, and easier to maintain. When others see a bottleneck, I see an opportunity to optimize. My unique skill set lies in blending backend development with DevOps, ensuring that applications run smoothly while remaining scalable and cost-effective. I’m always eager to collaborate with teams that value clean code, performance, and reliability. I’m open to remote opportunities where I can contribute my expertise in Rails, Postgres, and system architecture. Let’s build something great together!
