What I'm looking for

I'm looking to build and lead production data, platform, and infrastructure systems where streaming, distributed systems, Kubernetes, cloud infrastructure, and operational reliability matter.

I've built and operated production data infrastructure across trading, aerodynamics, and air-gapped defense environments. At Aerodynamics, I run Kafka and RabbitMQ on Kubernetes and redesigned a monolith into a stateful PyFlink streaming architecture processing terabytes across roughly 40 concurrent 4K streams.

I built an Elasticsearch and S3 data lake of roughly 3 million records, reducing worst-case queries from 20 minutes to 25 seconds. I also delivered an automated GitLab CI, DVC, and CML evaluation gate that halved observed delivery time to production from about 14 to 7 days.

At Algotitan, I rescued and completed an AWS migration while reducing projected monthly infrastructure costs by about half. I designed Pulumi infrastructure across environments, GitOps delivery with encrypted secrets, and a redesigned eight-microservice architecture on PostgreSQL.

I've also built bare-metal Kubernetes, GitOps, observability, virtualization, and nationwide network infrastructure in an air-gapped governmental environment. I maintain Matyan, a distributed ML experiment tracker built around FoundationDB, Kafka, and Kubernetes.
