What I'm looking for

I’m looking to lead cloud-native architecture and DevOps for real-time, high-scale systems—where I can pair streaming infrastructure with AI/ML and LLMs, mentor teams, and own reliability, performance, and measurable business impact.

I’m a Staff DevOps and Solutions Architect with 23+ years of experience, focused on AWS cloud systems and high-throughput architectures. I specialize in scalable microservices, real-time streaming, and AI-powered features that improve operational efficiency and business outcomes.

In my current role at LeanTech, I architected and implemented a real-time device monitoring platform for Cox Communications, processing telemetry from 6.2M+ devices with sub-second latency. I designed event-driven pipelines using Apache Kafka and AWS (Lambda, Kinesis Data Streams, Kinesis Firehose), built analytical querying with AWS Athena, and integrated OpenAI APIs and LLMs for intelligent alerting and automated incident analysis.

I’ve also led platform evolution and engineering delivery across teams and domains—migrating services from Heroku to AWS, integrating ERP systems, redesigning payment-processing architectures, and coordinating multi-disciplinary teams. I bring an engineering-first ethos: mentor teams on cloud-native and streaming patterns, drive architecture evolution, and deliver enterprise-grade systems with reliability, observability, and measurable performance.
