What I'm looking for

I'm targeting roles where engineering depth matters.

At Systems Limited, I developed RESTful APIs with Java 21 and Spring Boot, modeled PostgreSQL data layers, and configured OAuth2/Keycloak access control. I also added resilience and idempotency measures and containerized the application stack with Docker Compose.

I built Jarvis 2.0, a voice operating system that combines speech recognition, intent classification, and multi-agent tool execution. In VERA, I designed a five-agent AI tutor and an automated evaluation loop that improved benchmark accuracy from 58% to 87.9%.
