I’m a Computer Science graduate building cloud infrastructure and backend services with a focus on reliability, security, and performance. I enjoy turning real requirements into measurable outcomes—especially when cloud architecture and application design work together.

Recently, I worked as an Intern in Product Engineering and Service Operations at Qvantel, where I gained hands-on exposure to IoT hardware integration and real-time device communication workflows. I supported ingesting real-time device data using MQTT pipelines and Java-based middleware, assisted server-side debugging, and worked on API-level integration between edge devices and cloud systems.

In my projects, I’ve built AWS-based distributed systems end-to-end and tuned them with data-driven testing. For BookMyStay, I designed and deployed an AWS hotel reservation system using EC2, Amazon RDS (PostgreSQL), ElastiCache (Redis), private subnets, IAM, Secrets Manager, and CloudWatch; load testing and optimization improved throughput by 56% (1,722 → 2,687 requests/sec) and reduced P95 latency by 70.8% (612 ms → 178 ms). I also used Redis caching to cut Amazon RDS CPU utilization by 91% while serving 146,000+ cache hits, and strengthened operations and security with S3 pre-signed uploads, monitoring, alarms, and SNS notifications.

I also built KrishiSakhi-AI, combining secure backend development with AI and integrations. I implemented JWT-based onboarding with Temporary-to-Permanent user transition logic, engineered an autonomous AI agent using contextual data injection via the Gemini/OpenAI APIs, and orchestrated Twilio plus geospatial services to automate localized capture and mobile-first authentication; my work was reinforced through leadership as a Hackathon Team Lead and achieving Runner-Up at Smart India Hackathon (SIH) 2025.
