Summary
👤
Senior🎓
Top SchoolNeils Christoffersen is a Senior Software Developer with 14 years of experience building full-stack APIs and web applications, particularly in shipping, logistics, and enterprise software. He brings deep expertise in Ruby on Rails and ASP.NET MVC/WebAPI, strong backend skills in C#, SQL Server/Postgres, and a practical DevOps background automating Windows deployments with tools like Jenkins, Octopus, Packer, and Vagrant. Comfortable leading integrations against complex carrier specs and designing resilient systems, he has repeatedly moved projects from consultant-driven to in-house ownership while mentoring teams. Neils pairs a systems-minded IT operations history (F5, SANs, Cisco) with hands-on feature delivery, which helps him bridge development and infrastructure gaps others miss. Known for thoughtful communication and consensus-building, he prefers improving team processes as much as shipping code. Based in Moorhead, MN, he combines analytical curiosity with adaptability to tackle both greenfield APIs and legacy modernization work.
