Aaron Allen

I am a Senior Java Full Stack Developer with 9+ years building scalable, secure enterprise applications for federal agencies and financial services. I specialize in Java, Spring Boot, Angular (2+), and AWS, and I architect greenfield projects from design through production.

I've led Agile teams, mentored junior engineers, and enforced engineering best practices including Test Driven Development and code reviews to deliver mission-critical systems with high uptime. I design performant RESTful and GraphQL APIs backed by PostgreSQL, MongoDB, and SQL Server.

My work includes implementing microservices, background processing pipelines, and CI/CD automation using GitHub Actions and Azure DevOps to reduce deployment times and improve throughput. I focus on secure authentication/authorization (OAuth2, JWT, RBAC) and meeting federal security standards, including SOC 2 alignment.

I bring strong problem-solving, performance optimization, and cross-functional collaboration skills, with measurable impacts such as reducing latency by 35% and improving throughput by 45%. I seek to continue delivering production-ready solutions that balance reliability, scalability, and maintainability.
