Where I've worked

Software Engineer
ZMQ Development - New Delhi Jul 2022 - Apr 2026
  • Designed stateless Spring Boot REST APIs secured with JWT and OAuth2 behind an API Gateway, enabling scalable and secure service exposure
  • Built asynchronous event-driven pipelines using Apache Kafka and RabbitMQ with Spring Cloud Stream, improving system decoupling and throughput
  • Architected GitOps CI/CD workflows using GitHub Actions, FluxCD, Helm and Kubernetes on GCP - enabling automated, repeatable deployments
  • Integrated RAG architecture with Qdrant vector database and OpenAI/LLaMA APIs for intelligent AI-powered query responses
  • Optimized MySQL schemas and queries through indexing and query tuning, reducing average response time significantly
  • Established centralized observability using Grafana and Loki, improving incident response time and system visibility
  • Implemented Redis-based caching, pagination and global exception handling, improving API reliability and reducing database load
Software Engineer - Trainee
ZMQ Development - New Delhi Apr 2022 - Jun 2022
  • Contributed to backend feature development using Java, Spring Boot and MySQL
  • Practiced Git-based version control and participated in code reviews to establish engineering best practices
