Hello, I'm Viswanathan. I'm a Software Engineer with 4+ years of experience. I build backend systems, automate workflows with Python & Shell, and ship reliable software at scale.
About me
I am a Software Engineer at Zoho Corporation with over 4 years of experience across the full software lifecycle — from building backend APIs and CLI automation tools to contributing to large-scale distributed systems and API gateways.
My core strength lies in backend engineering — designing reliable services, automating repetitive infrastructure tasks, and integrating external systems. I work across Python, Java, and Shell environments, and I am experienced with Docker, Kubernetes, and Google Cloud for deployment and operations.
Outside of work, I enjoy cricket, badminton, and chess. I am currently exploring AI agents and LLM tooling, and I follow the intersection of technology and markets closely.
