@yuvarajjayavel

Full-stack engineer with 4+ years of expertise in Ruby on Rails, React, and Node.js

India

I am a full-stack engineer with 4 years of experience, currently specializing in Ruby on Rails and React at Chronus, where I focus on performance engineering. My role involves owning critical metrics like page load times, cron job efficiency, and memory optimization. For instance, I reduced global average page load times from 2.08 to 1.64 seconds and elevated the product’s SUS score by 19.5 points, enhancing user experience.

Previously, at Casaretail.ai, I thrived in a polyglot environment, building features with React, Node.js, and Python. I also championed test coverage improvements (32% → 73%) and led the development of Retensee, a loyalty program serving 100k+ users.

My technical depth spans full-stack development, with projects like a Rails-based library management system (500+ users) and a Smart India Hackathon-winning solution using Django and MQTT. I actively contribute to open-source tools like Joplin and PostHog, merging fixes and features.

Combining a passion for performance optimization with versatility across languages and frameworks, I aim to deliver robust, user-centric solutions. My work is driven by metrics, collaboration, and a commitment to code quality—evident in my career achievements and open-source contributions.
