At EY (Ernst & Young), I architected and built the DPG FPO Platform, a live microservices platform serving 20,000+ registered FPO users. I used domain-driven service boundaries and PostgreSQL database-per-service design.
I implemented transactional outbox publishing with RabbitMQ to support reliable CQRS read-model projections, and designed gRPC communication between services. I also integrated Keycloak for OAuth2/OIDC authentication and role-based access control.
At Markopolo AI, I built Marktag, a server-side first-party tracking solution that improved web tracking accuracy by 40% and reduced data loss by 35%. Its Kafka-based pipeline ingested 30–50 clickstream events per second.
I'm building Campgain.io, a multichannel marketing automation SaaS for Shopify and D2C merchants. I also built an AI Mentor Platform with multi-persona RAG, long-term memory using pgvector, and token-by-token response streaming over SSE.
