What I'm looking for

I’m looking for a remote-first, fast-paced team where I can build scalable Ruby on Rails + React applications, optimize performance, and deliver reliable APIs using AWS. I want to collaborate in Agile, solve complex challenges, and mentor others.

I’m a dynamic, detail-oriented FullStack Software Developer with 5+ years of experience specializing in Ruby on Rails and ReactJS. I design scalable backend architectures, create intuitive user interfaces, and deliver high-quality, maintainable code—especially through robust APIs and performance optimization.

In my current role, I led development of configurable forms and workflows, built complex backend processes in Ruby on Rails, and integrated ReactJS components for seamless user experiences. I also improved reliability with automated testing pipelines using RSpec (reducing production bugs by 30%) and optimized database queries to improve API response times by 40%, leveraging AWS services like S3, SES, and SQS. I enjoy working in Agile, collaborating cross-functionally, and mentoring junior developers while solving complex technical challenges in fast-paced, remote-first environments.
