What I'm looking for

I am looking for a role that emphasizes DevOps practices and offers opportunities for mentoring developers.

I'm a Senior Ruby on Rails Engineer with over 8 years of experience in building scalable, high-performance web applications. My expertise lies in Ruby on Rails, PostgreSQL, Redis, and Sidekiq Pro, complemented by strong frontend capabilities in React, TypeScript, and Redux. Throughout my career, I have successfully delivered production-grade systems with a keen focus on testing, code quality, and DevOps integration using Docker, Kubernetes, and AWS.

In my recent role at Popmenu, LLC, I architected a multi-tenant ordering system that supports over 2 million transactions monthly. I implemented Redis-backed caching and database indexing, which significantly reduced API response times by 60% under heavy traffic. My commitment to engineering excellence is evident in my mentoring of junior developers and leading architecture planning, all aimed at optimizing system performance to drive business outcomes.

I am now seeking a new role that allows me to leverage my DevOps practices and continue mentoring developers to elevate engineering excellence within a dynamic team.
