Experience

Member of Technical Staff

Zoho Corporation (ServiceDesk Plus Cloud) · Jun 2019 - Present · Chennai, India
  • Architected a natural-language chatbot and scalable LLM tool-calling API framework optimized for a compact 32B parameter LLM, driving product-wide adoption of ~200 API tools and achieving feature parity with market leaders.
  • Engineered a stateless, payload-driven context management system with custom execution loops to orchestrate complex workflows without massive frontier models.
  • Architected a comprehensive AI-driven SDLC ecosystem that automates the end-to-end development lifecycle—from PRD generation and feature implementation to automated test case creation—significantly accelerating the shipping lifecycle and minimizing manual engineering effort.
  • Led contextual AI innovation by implementing Agentic AI integration, RAG-based code generation, LLM summaries, and translations, which directly resulted in a 30% boost in customer satisfaction.
  • Designed the integration architecture between distributed similarity-search services and our core platform, implementing an LLM-based augmentation layer to derive value from historical data.
  • Developed a declarative AI framework using static definitions to standardize GenAI feature development across teams, reducing boilerplate code and increasing overall developer productivity.
  • Steered architectural integrity by authoring technical specifications for 30+ high-impact features, while mentoring 5+ engineers to establish team-wide best practices for AI-driven development.
  • Modernized core infrastructure by refactoring legacy Struts/JSP into a modular, API-first architecture (Java 8, SQL, Kafka), improving scalability and boosting API performance by 20%.
  • Orchestrated global-scale data migrations involving 1M+ production records with zero downtime, maintaining strict data integrity and system availability.
  • Optimized performance bottlenecks: Enhanced a legacy time-calculation engine's efficiency by 25% through algorithmic refinements.
