Experience
Connected Vehicle Telemetry Platform for a Fortune 500 Automotive Manufacturer
I designed and hardened the back-end telemetry infrastructure for a global automotive manufacturer's connected-vehicle platform, supporting 10+ million vehicles concurrently connected and streaming diagnostic, telemetry, and video data. I led reliability engineering efforts, including SLO/SLA framework design and multi-region disaster recovery with automated failover. I ran chaos engineering exercises with Gremlin to validate resilience to failures under real-world network and node conditions. I also led OWASP penetration testing and Gatling/JMeter load testing to validate the platform against production-scale traffic before rollout.
Blockchain Payment Infrastructure for a Global Payments Network
I built smart-contract infrastructure for a permissioned blockchain network at a major global payments company using Hyperledger Besu with Proof-of-Authority (QBFT) consensus. I architected an active/active multi-region topology with a tie-breaker witness zone to preserve consensus availability during regional failover. I implemented network segmentation and service-to-service security using Calico SDN and an Istio/Envoy service mesh, ensuring the payment network met the reliability and isolation requirements of financial-grade distributed ledger infrastructure.
Computational Hydrology, Environmental Compliance, and Storm Data Platform
I co-founded, roadmapped, architected, and engineered a full-stack platform for stormwater compliance that combines computational hydrology with modern data and mobile architectures. I built hydrologic/hydraulic modeling workflows to process rainfall-runoff and storm-event data, backed by a PostgreSQL time-series data architecture that handles millions of storm-cell records (including a 7.2-million-row batched purge-and-partition strategy to improve query performance at scale).
I also integrated GIS and geospatial tooling to map watershed and infrastructure data, and developed a mobile field-inspection app using augmented reality and computer vision to take on-site measurements and overlay CV-based detection of BMP (Best Management Practice) deficiencies during inspections, with underground infrastructure visualization planned as a future capability. I led business and governance strategy for the venture, including equity/IP structuring and EnviroCert (CPSWQ, CPESC) credentialing governance.
