At Rezo.ai, I build production AI customer-interaction systems handling 4L+ daily interactions and 1000+ concurrent requests per minute.
I developed a multilingual voicebot that combines LLMs, speech recognition, and speech synthesis to understand customer intent and respond in context. Its workflows support query resolution, lead generation, fallback handling, and escalation to a live agent.
I also built Java and Spring Boot services and asynchronous pipelines with Amazon SQS for customer data processing and CRM integrations. On dealer onboarding, showroom management, and complaint-handling systems, query optimization and backend refactoring reduced API latency by 30–40% and lowered database load.
For my E-Commerce Backend System project, I built a Java and Spring Boot backend with REST APIs, JWT and OAuth2 authentication, Redis caching, and Stripe payment workflows. I containerized and deployed it using Docker on AWS EC2 and RDS.
