What I'm looking for

I want to build high-throughput backend services with event-driven workflows and real-time user experiences, owning end-to-end systems and collaborating with teams that value reliability, observability, and fast iteration.

I’m a Software Development Engineer-1 who loves building reliable, high-throughput systems—especially where event-driven design and real-time updates directly improve user and operations. I’ve worked across backend services, dashboards, and API-driven platforms, with a focus on consistency, idempotency, and measurable performance gains.

At Fairdeal.Market, I migrated report generation to an AWS SQS–based event-driven architecture, cutting request failures by 90% at peak load and boosting throughput from 200 to 800+ jobs/hour. I also built a rule-based cashback system with async processing, implemented a “Notify Me” restock flow, and owned end-to-end backend development of VendorsPilot—eliminating manual reconciliation and reducing operational effort by 60%.

I’ve continued this momentum at Vodafone Idea, where I built React.js KPI dashboards for large hourly data feeds, delivered Chart.js-powered insights across 10,000+ data points, and architected PostgreSQL-backed REST APIs for low-latency ingestion. Earlier, as a software developer intern, I upgraded an EdTech web portal with React and HTML/CSS improvements, while creating backend RESTful APIs and unit tests to streamline user operations.
