Madhu Polisetti

I modernize the infrastructure and API platforms behind net2phone's voice & messaging products.

12+ years building backend platforms for a global VoIP provider. This past year: migrated net2phone's infrastructure to AWS CDK, modernized the public API gateway, and shipped a run of platform upgrades — from pod-based deployments to a same-sprint .NET 10 migration.

About

Madhu Polisetti

I've spent my career on the backend of communication products — telephony routing, public APIs, and lately the infrastructure-as-code that deploys all of it. I've led cross-continental teams, written the OpenAPI specs other teams build against, and migrated net2phone's core services off Terraform onto AWS CDK.

Outside of shipping code: sci-fi, long drives into the mountains, and following wherever the AI-tooling space moves next.
