I build backend systems that handle real traffic — REST APIs, WebSocket layers, and the deployment pipelines that keep them running.
Currently working at TEIM Pune on Java-based REST services in a Kubernetes/OpenShift environment. Before that I shipped a full platform at Quikkonnect — 25+ APIs, JWT/RBAC auth, WebSocket notifications, 40% query improvement.
My open-source contribution to Activepieces (20.9k ⭐) is live in production — a complete SmartSuite integration that passed maintainer review.
