Experience

Jio Platforms — Software Development Engineer III

Mumbai, India | August 2023 - Present

• Designed and implemented a Go-based Data Center Infrastructure Management (DCIM) system managing 10,000+ servers, replacing Excel-based workflows and reducing manual inventory updates by 70%.
• Designed and integrated a centralized IAM system using OAuth2/OIDC (Keycloak) and OpenFGA, enabling fine-grained RBAC and ABAC across 5+ services with JWT-based authentication.
• Designed fault-tolerant, event-driven distributed workflow orchestration using Temporal to handle asynchronous requests, enabling automatic retries and 100% reliability for critical services.
• Improved DCIM API latency by 30% by parallelizing external I/O calls using Go goroutines, eliminating sequential bottlenecks and improving performance under high concurrency.
• Authored High-Level Design (HLD) and Low-Level Design (LLD) for DCIM and IPAM systems; applied Domain-Driven Design (DDD) to improve implementation speed and maintainability.
• Integrated Piper TTS with a Python-based backend for low-latency speech synthesis via REST APIs; managed model versioning and hot-reload in Docker, reducing response time by 20%.
• Developed Python and Go-based automation scripts for DNS management, database backups, Excel workflows, and cluster provisioning, reducing manual effort by 50-80%.
• Designed, deployed, and managed cloud-native microservices using Docker and Kubernetes with rolling updates, resource tuning, and PVC-backed storage.
