About
I’m Kevin Monagle, a senior full-stack software engineer based in Hummelstown, Pennsylvania, focused on building modern web and mobile systems with strong engineering fundamentals and fast delivery. I’ve been a core contributor to re-architecting a legacy .NET/Kafka healthcare platform into a modern JavaScript system, and I’ve also built a three-tier productivity application end-to-end—owning product decisions, workflows, UX direction, and the full engineering stack from backend APIs to React and React Native clients.
I’m especially interested in practical AI engineering—designing RAG pipelines, and developing multi-agent orchestration for real workflows. Throughout my career, I’ve led teams, mentored engineers, improved reliability and performance, and strengthened test automation and observability, consistently with clear communication and cross-functional partnership as a core part of how I work.

Owned product decisions, user workflows, and UX design alongside the full engineering stack, leveraging modern AI-enabled tooling for rapid prototyping and high delivery velocity.
Led development of secure messaging and resource library React/AWS applications during a company-wide rearchitecture, directing a 5-person team and coordinating with internal groups, partners, and vendors. Built configurable React applications (feature flags, dynamic layouts, client-level configuration) and backend APIs using Node.js and AWS Lambda in a serverless architecture. Contributed to rebuilding a legacy .NET/Kafka healthcare platform into modern full-stack JavaScript, including benefit verifications, patient enrollments, staff management, and drug manufacturer programs. Implemented Playwright UI test automation, performed MongoDB v4→v7 migration, improved logging infrastructure to reduce annual storage costs by $70,000+.
Led design and development of Angular, Express, and Sails applications for education assessment platforms. Modernized legacy code by expanding RxJS usage and applying reactive patterns, and increased automated test coverage from 40% to 75%.
