Senior Ruby on Rails Engineer | Backend Architect | System Design Specialist

I'm a Senior Ruby on Rails Engineer with 9+ years of experience building and scaling web applications. I focus on creating reliable, high-performance systems that are easy to maintain and grow as products evolve.

I've worked across a diverse set of industries including Healthcare, Finance, E-commerce, Education, Telecom, Marketing, Property Rental, Hospitality, Insurance, and more. This range of experience helps me quickly understand different business needs and turn them into practical, effective technical solutions.

My expertise lies in backend development, API design, and database optimization, particularly with PostgreSQL. I have hands-on experience improving performance, handling high-traffic scenarios, and implementing efficient caching and background processing using tools like Redis. I also work with concurrency, threading, and system-level optimizations to ensure applications run smoothly under load.

I've contributed in different environments-working with small and large teams, collaborating with global stakeholders, and independently delivering complete solutions. I'm comfortable taking ownership, making technical decisions, and ensuring that projects move forward with clarity and quality.

I believe in writing clean, modular code and following best practices that keep systems stable and teams productive. Along with development, I focus on building scalable architectures, improving system visibility, and solving complex problems in a simple, efficient way.

Whether it's building from scratch, optimizing an existing system, or scaling a growing product, I aim to deliver solutions that create long-term value.
