  • Designed and built GraphQL API endpoints for a high-throughput, low-latency Network Management System (NMS), championing consistency standards that significantly improved developer velocity.
  • Delivered a greenfield NMS rewrite as lead developer, achieving 90% feature parity with the legacy system using only ~25% of the original LoC, dramatically reducing maintenance overhead (56k vs 255k LoC).
  • Developed a novel JSON validation framework that proved so robust it now auto-generates the team's API documentation - eliminating a manual documentation burden.
  • Built a proof-of-concept TCP/UDP monitoring server from scratch in Python, demonstrating 10 MB/s throughput at sub-10 ms latency before the project was paused.

  • Lead developer on the 'NEA Live' service - a SaaS platform enabling on-demand cloud resource provisioning for live sports broadcast over IP.
  • Managed direct stakeholder relationships with a partner company licensing the product, owning the API contract and delivery timeline end-to-end.

  • Core member of the ingestion & enrichment team for a Transaction Monitoring product serving 200+ clients, responsible for input validation, data enrichment, and storage design.
  • Co-designed a Kafka-based time-series aggregation microservice that scaled throughput from 5 tps to 500 tps (100× improvement) by replacing monolithic Postgres processing with a distributed, event-driven architecture.
  • Provided out-of-hours on-call support, making independent prioritisation decisions to restore service rapidly while maintaining SLA commitments for all clients.

  • Developed analysis automation tools that cut common engineering workflows from 1-2 weeks to under a day across three separate teams.
  • Results were so significant that Rolls-Royce's official corporate billing methodology was updated to incorporate the software outputs.
  • Acting team lead on a cross-functional ML investigation, applying machine-learning techniques to calibrate theoretical models against rig-test and in-service data.
  • Mentored colleagues formally for IMechE Chartered Engineer accreditation; consulted internally on in-service performance methodologies.

  • Quantified the relationship between weather conditions and anomalous engine performance - enabling extended time on-wing and generating an estimated $200M in additional revenue.
  • Head-hunted to lead a safety investigation in 2018; developed a technique to detect lagged sensor measurements, maintaining fleet airworthiness and avoiding an estimated £1M/day grounding cost.
  • Owned the production SQL Server engine-performance database; authored Rolls-Royce's corporate SQL training manual.
