What I'm looking for

I’m targeting opportunities in product-based or service-based teams focused on innovation and scalability—leveraging my expertise to architect high-performance applications, lead cloud migrations, and optimize CI/CD for faster, reliable releases.

I’m an accomplished Technical Lead with over 11 years of end-to-end full-stack development experience, specializing in Ruby on Rails, Angular, Microservices, and Cloud Architecture. I currently lead full-stack delivery at Encora for Mindbody Online in the wellness and fitness domain, partnering with cross-functional stakeholders to ship high-impact work in fast-paced environments.

I’ve spearheaded migrations and reliability improvements, including a seamless AWS migration with zero downtime practices to boost deployment efficiency and time-to-market. I’m equally focused on CI/CD pipeline optimization, testing strategies (RSpec, API testing), and performance tuning—supported by proactive monitoring that reduced incident resolution times and improved uptime—while mentoring teams and raising engineering quality through rigorous code reviews.
