Introduction
Data platform lead with 8 years across data engineering, backend systems and cloud architecture.

EMBD Finance acquired the Untapped Global data platform in March 2026; team, platform and scope carried over without interruption. - Designed and shipped the company's AI agent platform from scratch on top of the existing data pipeline, now running in production. An orchestration layer where specialist LLM agents select and sequence work over a shared execution runtime, with every executable step validated against JSON-Schema contracts. - Built the execution substrate that makes agent output auditable: a single run path producing provenance, quality gates and per-tenant usage metering automatically, so every record is traceable from source to output. - Deployed on AWS Bedrock behind a provider-agnostic model gateway, with Step Functions and Lambda for stateless per-step workers, ECS Fargate and Django/DRF for durable orchestration, and a React/TypeScript operator interface. - Designed the governance model for the skill library, CI schema validation and code ownership gates controlling what the runtime is permitted to execute. - Lead a cross-functional team of four (data analyst, two full-stack engineers, one DevOps) while owning platform architecture and contributing hands-on as data engineer. - Run data assessment interviews with portfolio companies, evaluating data infrastructure maturity to inform investment decisions.
