Experience
Sixteen years, mostly in banks
Started as a consultant in Bangalore in 2010, moved to Switzerland with the job, and have been building trading, onboarding and credit systems in Zurich since 2017. The thread through all of it: I end up owning quality and speed, not just features.

The pipeline rebuilt to take half the time
I lead a team of ten on the REST APIs behind mortgage credit decisions. When I joined, the build did everything on every run: unit and integration tests as one block, nothing cached, nothing reused, steps with no reason left to exist.
I took it apart and rebuilt it. Unit tests split from integration and run first, outputs cached across stages, dead steps gone. Time dropped by more than half. Embedded Kafka lets the team verify business logic on their own machines instead of waiting for the integration environment, and framework upgrades go through OpenRewrite recipes.

Load tests that stopped being a release event
Onboarding needed new Spring Boot services and a separate authentication service with JWT and role-based access. The question nobody could answer was how it behaved under load until the week before release.
I put Gatling into the CI pipeline so every build answered it. Underneath that, a test matrix: REST Assured for API contracts, Cucumber for business journeys, JUnit 5 and Mockito for the rest.

The build that got its ten minutes back
I led ten engineers on client data infrastructure and the regulatory engines (FINIG, MiFID) behind the trading platform, with REST and GraphQL APIs side by side and data flowing both ways.
The build took nineteen minutes. I profiled it like a production problem and brought it to nine, then set up the CI/CD pipeline with Cucumber acceptance tests and built the Splunk dashboards the team watched in production.
