Fullstack Web App Developer

I am a fullstack, web app developer, but I do prefer backend work and am pretty good at integrations. I have 5 years of experience writing full-stack, tested, and validated code across several projects at a software consulting firm. I worked directly with clients and led internal teams to meet clients' business goals. Basically, I have experience solving a wide array of problems spanning a variety of industries, and I care about the product and its users. I'm looking for a senior/senior-track software engineering role at a product-focused company that takes testing and code quality seriously! The reason I'm moving on from my previous role is to learn new things - so a Ruby on Rails/Javascript project would be great, but I'm here to learn! I also want to work with developers who know more than me so I can learn from them.
