At ClickWise, I decomposed a monolith into four event-driven microservices, using SAGA and the Outbox Pattern to improve availability and eliminate silent message loss. I also delivered production services end to end, from architecture through deployment and monitoring.
I automated AWS CI/CD pipelines with CodePipeline and CodeBuild, reducing regression testing time by 55% and eliminating manual deployments. I also cut AWS infrastructure costs by 30% by replacing polling-based report ingestion with event-driven AWS Lambda.
At Capgemini Engineering, I built NestJS microservices and a BFF gateway for an enterprise request-tracking CMS. I implemented RabbitMQ messaging with dead-letter queues and idempotent consumers, and optimized PostgreSQL queries to cut latency by up to 40%.
On an advertising platform for the EU market, I built NestJS services and REST APIs for targeting, campaigns, and audience segmentation. I also built reusable React components and set up Slack alerts that cut incident detection time from days to minutes.
