About Mohan Ganesh

Mohan Ganesh is Software Architect with over two decades of hands-on experience designing and delivering enterprise-scale solutions across healthcare, insurance, and digital domains. My career has been fueled by a passion for exploring emerging technologies and building innovative products that create real impact. I have a keen eye for identifying strategic opportunities and leading cross-functional teams to deliver impactful changes that drive business growth and create meaningful value for customers.

I have a strong background in cloud computing, microservices architecture, and application modernization, with a focus on Google Cloud Platform (GCP), where my expertise is validated by Professional Cloud Architect and Cloud Security Engineer certifications. I have designed and built secure, scalable products that leverage Google Gemini and RAG to create AI Agents that automate complex tasks. I believe in not just using tools/frameworks but improving them. As an active open-source contributor, I recently contributed the Firestore Session Service extension for the Google Agent SDK, which was officially accepted and merged into the project repository. This contribution addressed critical production-readiness gaps I identified while building enterprise solutions. I am also an active contributor to the Spring Boot framework.

Throughout his career, Mohan has demonstrated a consistent ability to lead critical initiatives. At Highmark Health, he is currently spearheading the modernization of the call center platform and redesigning the member-facing chat experience with conversational AI. While at CVS Health, he led the cloud migration for key digital platforms, achieving a 40% reduction in latency. His leadership in adopting DevOps best practices has resulted in a 50% improvement in deployment frequency.
