About.

/01

I'm a backend engineer. Been doing this for 5 years at Intelligent Buildings — a company that makes software for smart commercial buildings. My day-to-day is Java and Python, building the APIs and data pipelines that connect HVAC systems, sensors, and energy meters across thousands of buildings.

Currently finishing my BS in Technology & Business at the University of Memphis while working full-time. I'm available for remote roles, full-time or contract.

Intelligent Buildings
  • 2025–2026: Integrated AI/ML models into the building-automation platform — anomaly detection on sensor streams and predictive maintenance — cutting false alerts and unplanned downtime.
  • Designed and shipped production REST APIs and microservices in Java/Spring Boot powering a smart building IoT platform — serving live data from HVAC, access control, energy meters, and sensors across thousands of buildings globally.
  • Built real-time ingestion pipelines using Elasticsearch to process high-volume building telemetry at scale — feeding operational dashboards and automated alerting systems with sub-second latency.
  • Led backend architecture for IntelliNet, a 24/7 monitoring and cybersecurity SaaS product — owned API design, database schema, and service reliability for a platform deployed across billions of sq ft of commercial real estate.
  • Built protocol integrations for BACnet, Modbus, and MQTT — normalized fragmented vendor data from 30+ device types into a single unified API layer consumed by frontend clients and third-party systems.
  • Reduced API p95 latency by 60% through Redis caching, query optimization, and strategic indexing across PostgreSQL and MongoDB — measured and validated with load testing.
  • Work in a cross-functional team with IT/OT engineers, cybersecurity consultants, and PMs — two-week sprints, code reviews, on-call rotation for production incidents.
