Prathmesh Bhardwaj

Backend engineer in Bangalore, India. I build APIs, realtime systems, and the plumbing behind AI products, and I like software that stays simple.

I'm a software engineer at Rocketium, the AI creative-automation platform that enterprise marketing teams use to produce campaign-ready images and videos at scale. I work on the backend: the services and APIs behind the platform, and keeping them fast, reliable, and secure.

VoiceFlow

CodeLive demo

Multi-tenant platform for AI voice agents. It runs outbound call campaigns, bridges Twilio media streams to a realtime model for live conversations, answers from uploaded documents with RAG, and writes a summary after each call. Each tenant brings its own credentials, encrypted at rest.

LLM CostGuardTeam project

Code

OpenAI-compatible gateway that cuts LLM spend with exact and semantic caching, context trimming, prompt compression, and eval-gated model routing. In an A/B run on a frozen request trace, it cut cost by 57.7% and kept 99.3% of answer quality.

Python, FastAPI, Qdrant, Prometheus

FanDial

Code

macOS menu-bar app that sets fan speed with a rotary dial. It talks to the SMC through IOKit and works around the thermal-manager lock that M3 and M4 Macs put on fan writes.
