What I'm looking for

I'm looking to build and operate complex backend, distributed, fintech, language-tooling, or data systems end-to-end, with opportunities to shape architecture, infrastructure, testing, deployment, and production reliability.

I'm building and maintaining Java services at Checkoff on Apache Fineract for savings, loans, transaction processing, and financial reporting. I also own Terraform-provisioned AWS infrastructure, CI/CD maintenance, and Docker/Kubernetes deployments.

Previously, I built SQL compilers and Java WebSocket tooling at Periteleios, Node.js and TypeScript workflows for configurable AI agents at Upfirst, and Fineract-based savings systems at Dedukt that reduced operational workload by 30%.
