Hands-on technical leader with 9+ years building distributed backend platforms and external APIs. Tech Lead for External APIs on my latest project, leading 9 engineers across parallel workstreams and owning architecture and engineering standards for a platform handling ~1M events/day. Experienced in complex migrations, including serverless-to-Kubernetes re-platforms and zero-disruption cutovers, and in shipping independent products from idea to production.

Tech Lead, External APIs

Jul 2025 - Present · London

Technical lead for a team of 9 engineers across multiple parallel workstreams, working closely with product, delivery and the technical architect, building the external API platform behind reservations, availability and pre-booking: the integration surface for 5 major third-party clients, with more onboarding.

Designed and built the event-driven webhook delivery platform behind every external client integration: ~1M events/day on AWS EventBridge and BullMQ/Redis, with HMAC-signed payloads, per-subscription circuit breakers, rate limiting, exponential-backoff retries and a Postgres-backed dead-letter queue.
Re-platformed a high-volume data service from AWS Lambda to a long-running EKS service, removing timeout ceilings and cold starts while adding back-pressure handling, resumability and full observability.
Authored the platform's push-to-pull integration strategy (operation-status endpoints with Retry-After and ETag semantics) and its four-phase rollout, cutting integration cost for clients.
Own the shared authentication and authorisation tooling used across the external APIs estate.
Set the platform's engineering standards: outbox publishing, idempotent mutations, correlation-ID tracing and Datadog observability.
Introduced team-wide use of AI coding agents and agentic workflows across design, delivery and code review, raising throughput without lowering standards.
