What I'm looking for

I'm looking for opportunities where network automation is needed.

At Estee Advisors Pvt. Ltd, I maintain network infrastructure and production systems, provision servers, and support new client onboarding. I automate repetitive maintenance tasks with Python and Ansible.

At National Payments Corporation of India, I developed network automation including a Python crawler for NAT monitoring and a portal-based DR drill solution that reduced the drill window from 10 minutes to under 60 seconds. I also contributed to the CBDC app backend, a TypeScript validation gateway deployed with Kubernetes.
