What I'm looking for

I'm looking to build high-impact internal platforms and automation, with ownership of cloud-native systems, measurable reliability and latency improvements, and stronger developer experience.

At Presidio, I build unified internal platforms with FastAPI, Django, React, AWS EKS, and Kubernetes. I consolidated disparate tools, reduced operational scripts by 60%, and automated workflows that save approximately 25 developer hours each week.

I modernize legacy systems into containerized microservices, improve PostgreSQL performance, and build deployment pipelines with Helm and GitHub Actions. My work has reduced deployment lead time by 70%, lowered infrastructure costs by 35%, and supported 99.9% availability for critical internal portals.

Previously at Rackspace Technology and RealPage, I delivered Python backend services, React interfaces, event-driven Kafka and Celery workflows, CI/CD automation, and observability for internal and customer-facing products.
