What I'm looking for

I seek a challenging engineering role where I can lead API-driven projects, improve performance, mentor teams, and drive cloud-native CI/CD practices in an agile, collaborative environment.

I am a results-driven software engineer with over 4 years of experience building scalable web applications using Ruby on Rails and React. I focus on performance, reliability, and delivering user-focused features.

In my recent work I led development of an Approvals module that increased operational efficiency by 30% and optimized RESTful APIs to reduce response times by 40% through query optimization, caching, and indexing. I have driven migrations across Ruby and Rails versions to modernize stacks and improve runtime efficiency.

I collaborate closely with Product, Design, QA, and DevOps to deliver well-tested features, consistently meeting sprint goals and maintaining CI/CD pipelines. I have hands-on experience with cloud deployment (AWS, Heroku), containerization (Docker), and test automation using RSpec, Minitest, Cypress, Selenium, and Watir.

I seek to contribute technical expertise and leadership in challenging engineering roles where I can build reliable API-driven systems, mentor teammates, and continuously improve performance and developer experience.
