At OOMSYS Technologies, I work on NIBC Insurance’s policy administration and claims platform, where I engineered Java and Spring Boot microservices and integrated AI assistants using Spring AI and LangChain4j. RAG with PGVector and Pinecone made document retrieval 60% faster.
For OakNorth Bank, I built microservices for lending, onboarding, repayments, and credit assessment, and helped modernize legacy banking systems. The platform delivered 12+ microservices, with loan approvals 35% faster and 99.9% uptime.
At OnBuy, I developed services for catalog, inventory, orders, and payments, along with an Angular marketplace interface. Redis caching improved product search speed by 40%, while Kafka-based event processing made orders 30% faster.
