WORK HISTORY
Java Software Engineer @Ocado Technology
London, GB
Backend engineer in the Availability & Stock Management team, building and scaling AWS-based microservices to optimise real-time product availability. Supported production systems, onboarded engineers, and drove cross-team ownership transitions. Led and developed various initiatives:• Led discovery of a large-scale feature for creating pre-checkout allocations, integrating a new microservice with Ecom and multiple supply chain systems. Made key architectural decisions to ensure scalability, safe rollback, and future extensibility. Reduced non-fulfilment rates and enabled feature adoption by other retailers.• Designed and implemented an SQS FIFO queue proxy for deduplication to prevent concurrency conflicts, optimised batch API usage to significantly lower latency by 75%, and enhanced observability via custom Grafana metrics for the pre-checkout allocations feature.• Spearheaded discovery and implementation for a bulk CSV upload feature requiring work in two Java backend services and one TypeScript/React frontend service. Saved clients’ demand planners over 2 hours/week.• Engineered and deployed sophisticated Java-based core business logic to tackle the complex problem of minimising cascading substitutions in customer orders, reducing such shorts by a margin of more than 50%.
