Results-driven Backend Software Engineer with experience building scalable, fault-tolerant distributed systems and high-throughput microservices using Golang. Specialized in event-driven architectures leveraging Apache Kafka, MQTT, and gRPC, alongside robust persistence layers including PostgreSQL and Redis. Engineering expertise spans concurrent device management platforms, automated test engines, secure OAuth2/Keycloak authentication flows, and containerized deployments using Docker.

Software Engineer at Infernet Systems (2025-03 – Present)

Building a high-scale device management platform and cloud analytics infrastructure in Golang.

• Xunison Device Platform: Implemented TR-069 for large-scale device provisioning and remote diagnostics; integrated MQTT for real-time, low-latency device telemetry and bidirectional streaming across IoT clusters.
• Identity & Access Security: Architected centralized authentication using Keycloak and OAuth2 with granular Role-Based Access Control (RBAC) and social login integrations.
• OpenWiFi Cloud Analytics: Designed a microservices architecture with dynamic service discovery, gRPC inter-service communication, and high-throughput Apache Kafka pub-sub pipelines with partition routing.
• Fault Tolerance & Caching: Engineered resilient retry pipelines with Dead Letter Queues (DLQ) and multi-tier Redis caching, optimizing PostgreSQL queries and reducing overall API latency.

Associate Software Engineer at Wits Innovation Lab (2023-11 – 2025-03)

Engineered concurrent ONDC automation workflows and event-driven NPS analytics microservices.

• Paraman ONDC Engine: Built a high-concurrency test automation engine in Golang; resolved race conditions and optimized goroutine memory execution pools for parallel validation bursts.
• Real-Time Streaming & Rate Limiting: Implemented Server-Sent Events (SSE) for instant task feedback; applied distributed rate limiting and Redis session state management to protect API endpoints.
• NPS Event Driven System: Designed an event-driven platform with Apache Kafka producers and consumers, exponential-backoff retries, and Dead Letter Queues for fault tolerance.
• Database Optimization & DevOps: Optimized PostgreSQL schema indexing and queries; containerized core microservices using Docker for streamlined CI/CD deployments.

MERN Stack Developer Intern at Scizers Technologies (2023-04 – 2023-08)

Backend development for enterprise CRM applications.

• CRM Microservices: Developed backend RESTful microservices using Node.js, Express, and MongoDB for CRM lead lifecycle management.
• Access Control: Implemented RBAC middleware role security.
