PaulMaxwell
Software engineer. I build backend systems — platforms, data pipelines, and the services around them.
Currently at P-1 AI, working on the platform behind Archie, an AI engineering agent. Before that: fraud detection at Amazon, credit underwriting at Ampla, portfolio analytics at BlackRock.
Lead Software Engineer / P-1 AI / 2025 —
Archie BYOC Platform · P-1 AI
Deploys an engineering AI agent into customer-controlled cloud; each install assembles from independently versioned components.
Zero-Trust Agent Gateway · P-1 AI
A phantom-token pattern — agent code in ephemeral sandboxes holds only opaque, request-scoped tokens; the gateway keeps every real credential.
Duplicate-Invoice Detection · Amazon
Real-time duplicate-invoice detection (up to 500 TPS) with pluggable rule and ML engines, part of Amazon's fraud-prevention suite.
EU Compliance Ingestion · Amazon
Processes roughly one billion book titles per year, extracting required metadata and storing compliance artifacts at 500 TPS.
Transaction Tagging Engine · Ampla
Re-implemented with Aho–Corasick; runtime went from hours to 90 seconds.
