I've delivered production features and security remediations for KMS Technology's AU/NZ funeral-services workflows, spanning Angular, Firebase RTDB, Elasticsearch, and Node.js services. I standardised end-to-end delivery practices and resolved a cross-repository data-contract issue that blocked NZ supplier selection.
At Ancient8, I architected Dopamint's event-driven ranking engine with RabbitMQ and Redis Sorted Sets, sustaining 1k+ events per second at under 13ms P99 latency. I also reduced database IOPS by 60% through write-behind caching, bulk operations, and buffering strategies.
At Apollo, I led a migration from LoopBack 3 and Elasticsearch to NestJS and MySQL, built CDC pipelines, and integrated WSO2 IAM for centralised authentication. I created a reusable Elasticsearch pagination library that reduced feature development time by 70% across teams, while mentoring engineers through system design reviews.
Across Web3, e-commerce, healthcare, and threat-intelligence products, I build secure APIs, real-time data pipelines, authentication flows, and scalable backend services using NestJS, GraphQL, gRPC, cloud infrastructure, and modern frontend frameworks.
