Mid-level full stack Rails Dev looking for immediate placement.

In the fall of 2017 I enrolled in Case Western Reserve University's Coding Bootcamp, a 26 week program dedicated to teaching the fundamentals of Full Stack Web Development. Entering the course with no coding experience, I found myself struggling with certain concepts, but through determination I was able to gain a sturdy foundation for a future in web development. After completing the course in April 2018, I was able to get my foot in the door at Bravo Wellness as a QA Automation Engineer. After 2 years in that role, the company decided to transition to an entirely new platform that would be created using the Ruby on Rails (RoR) framework. The new software was called "Ovation" and I had the tremendous opportunity to learn from some great people (who I still keep in touch with via Discord & Slack). Shortly after Bravo Wellness was acquired by Medical Mutual I was offered an excellent opportunity with another local shop. Second Generation is a fast-paced small team where I continued to grow as a RoR developer; honing both my back end and front end skills. After some time I found my niche integrating two third-party providers via custom-built widgets. Unfortunately, in May 2024, due to cutbacks I've found myself looking for my next great adventure. I'm certainly open to suggestions, so stop by my Contact & Resume page for my professional networking links and contact information as well as my most current resume.
