I've built Java microservices and enterprise platforms serving telecom, banking, and automotive customers.
IndiaWhat I'm looking for
I've delivered enterprise Java applications for Quest Global, CGI, and Capgemini across telecom, banking, finance, and automotive platforms.
At Quest Global, I helped build Bell Canada’s IPTV migration platform, supporting 500K+ customer migrations through Java 17, Spring Boot microservices, AWS deployments, and resilient REST APIs. I improved quality with more than 85% test coverage, reduced critical SonarQube issues by about 35%, and supported zero-downtime blue-green releases.
Previously, I built banking order-management services processing 10K+ daily transactions and contributed to PSA’s EU-compliant automotive platform. I’m also exploring AI/LLM integration in Java with LangChain4j, Spring AI, RAG pipelines, vector stores, and agentic workflows.
