Professional Experience

Jan 2023 - Present
SVP - API Security Engineering Lead
Citi (London/Hybrid)

Leading the engineering strategy for secure API enablement, collaborating with Platform Architects to embed security into the platform lifecycle.

  • Abstracted API DAST Broker: Engineered an event-driven DAST-as-a-Service broker. Designed a scalable pseudo-synchronous pattern (Submit Ack → Async Scan → Response Topic) to decouple upstream consumers from underlying scanners (commercial/OSS), preventing vendor lock-in.
  • AI Innovation Strategy: Recommended the proposal and built the prototype of an AI-Powered Security Framework using Python and RAG to automate vulnerability remediation.
  • Platform Engineering: Architected the Apigee Hybrid runtime on GKE and managed the Cassandra data plane, utilizing Terraform for infrastructure provisioning.
Nov 2021 - Dec 2022
Senior Software Engineering Lead
William Hill (Leeds)
  • Legacy Migration: Led the migration of monolithic databases to AWS Cloud Native data stores (Aurora/DynamoDB) with zero data loss.
  • Infrastructure as Code: Enforced Terraform standards for all environment deployments.
Jul 2020 - Nov 2021
Service Lead / Tech Lead
Yorkshire Building Society (Leeds)
  • Data Integration: Architected patterns connecting legacy mainframes with modern microservices via RabbitMQ.
  • Platform Design: Designed the Google Cloud landing zone for secure database and API hosting.
Jul 2013 - Aug 2013
Senior SOA Integration Consultant
Financial Conduct Authority (FCA)
  • Government Delivery: Designed the "Bank Authorisation" integration program, engineering the secure transfer of large regulatory data payloads (MTOM) to Livelink repositories.
Earlier Career (1997 - 2013)
Principal Engineer & Integration Architect
Capital One, Capgemini, Wipro, GTNexus

Foundational experience in Data Engineering and Database Performance.

  • GTNexus/Pervasive: Engineered complex EDI data pipelines and performed deep-dive SQL/Btrieve database performance tuning.
  • Capital One: Designed Data Services and optimized PL/SQL logic for core banking processes.

Consulting Services

Available for high-impact contract engagements and strategic advisory roles.

Fractional Head of Engineering

Interim leadership to mobilize engineering labs, define cloud strategy, and optimize operating models.

Cloud Platform & Data Strategy

Architecting resilient Data Platforms (DBaaS), Infrastructure Automation (Terraform), and Cloud Migrations.

Security & DevSecOps

Deep-dive API Security reviews, "Secure by Design" implementation, and AI-assisted security workflows.
