About Jeffrey

Jeffrey P.Status: Offline
Senior Backend Engineer (Python) | AI & Compliance
5.0  (1 review)
New Bern, United States - 1:28 am local time
I build production-grade Python backend and API systems for AI-driven and regulated environments. My background includes JPMorgan, Lockheed Martin, and IBM Cloud, where scalability, auditability, and operational correctness are mandatory — not optional.

I specialize in backend architecture and production AI integration, including:

• FastAPI and high-throughput API design
• LLM (Large Language Models) and RAG system integration
• ETL and Airflow-based data pipelines
• PostgreSQL, Redis, and vector databases
• Docker, CI/CD, and AWS production deployments
• Performance tuning, concurrency models, and observability
• Audit-ready workflows (SBOM, SLSA-aligned builds, deterministic orchestration)

I do not build prototypes that collapse under load. I design systems intended for reliable production — with clear service boundaries, infrastructure discipline, and scalability in mind.

I work best with founders and engineering teams who need to:

• Move an AI prototype into production
• Harden a backend for scale and fault tolerance
• Clean up fragile APIs or performance bottlenecks
• Introduce structured auditability into workflows

If you need a senior backend engineer to own the system architecture and deliver production-ready implementation, we should talk.
