What I'm looking for

I'm looking to build AI-native customer-facing products, scalable backend systems, and intelligent data workflows where I can lead architecture, mentor engineers, and turn complex customer problems into shipped features.

I've built customer-facing SaaS workflows, AI agent systems, and scalable backend APIs across Sportify, Capital One, GEICO, and Raytheon.

At Sportify, I architect product workflows with Ruby on Rails, Sidekiq, PostgreSQL, AWS Bedrock, and vector search to automate complex tasks and deliver real-time intelligent recommendations. I also build React and TypeScript interfaces, containerize microservices on Amazon EKS, and establish observability, privacy, and reliability practices across product systems.

At Capital One, I led cross-functional squads building predictive AI data pipelines, feature stores, RESTful microservices, and real-time Kafka streaming workflows on AWS. I've mentored engineers, authored architecture specifications and runbooks, and translated operational needs into scalable technical roadmaps.

My foundation includes high-performance, secure software in Python, Java, C++, SQL, and cloud infrastructure. I use AI-assisted development tools such as Cursor, Claude Code, and Codex to accelerate high-quality engineering delivery.
