During my tenure at Zensar (April, 2021 : April 2023), I led the end‑to‑end development of a critical monitoring solution for Cisco, focused on tracking service health across SD‑WAN devices. The project was built on a robust backend stack: Django, Django REST Framework, and Celery for asynchronous task processing.
I took full ownership of the backend systems and the overall delivery, which included:
Architecture & development – designing the entire backend architecture, writing RESTful APIs, and integrating them seamlessly with the frontend.
Database & operations – managing all database migrations, ensuring data consistency, and implementing authentication and authorization layers.
Environment management – configuring dedicated development, QA, and production environments with environment‑specific settings, SSL certificates, host mappings, and URL routing.
DevOps & deployments – writing and managing builds, pushing and pulling container images, and handling complete deployments across all environments.
Team leadership – leading the team technically, coordinating frontend‑backend integration, and ensuring timely delivery of high‑quality code.
project was fun. – from writing build scripts to deploying on infrastructure(Cisco isolated Linux tools/server), configuring SSL termination for secure communication, and maintaining zero‑downtime updates across environments. This project sharpened my expertise in full‑stack Django development, distributed task processing with Celery, secure multi‑environment configuration, and team leadership in an enterprise setting.
