Senior Backend Engineer

I've done a little with a lot across my career. I'm looking for a senior or staff level role where I can use my skills of digging into existing legacy systems and developing greenfield backend applications, as well as mentor more junior engineers and help them develop their skills. I have quite a bit of experience with Rails but I'll work with just about anything. My post recent projects have been:
- Building a typed double entry accounting system in Rails with Sorbet
- Building an affiliates system for an e-commerce platform
- Debugging Wi-Fi issues for an IoT product
