Systems, shipped.

Sai Madhav builds production AI systems: realtime voice agents, multimodal pipelines and the infrastructure under them.

Manifesto

A model that works in a notebook is a different problem from one that has to answer a phone call.

I did not come to AI systems from research. I came from shipping, and from finding out repeatedly that the model is the small part. The rest is latency budgets, state that survives a pod restart, tenants that must never see each other's data, and a handoff to a human that cannot drop the conversation.

That is the work I do: the whole system around the model, designed, built and deployed.

Selected work

01

Realtime voice agents

Production voice bots built on a streaming speech-to-text, LLM and text-to-speech pipeline, then migrated to Gemini Live's native audio models. Call recordings are generated for every conversation.

Caller → STT → LLM → TTS → Caller

02

Human handoff across pods

Chatbots that pass a live conversation to a human agent. Redis pub/sub carries the transfer between Kubernetes pods, so it does not matter which pod holds the customer's connection and which holds the agent's.

Bot → Redis pub/sub → Agent, any pod

2025 — Now

03

Multi-tenant voice platform

Database and dashboard design for onboarding voice-agent customers: tenant isolation, role-based access control and the analytics dashboards each customer sees.

Tenant → Roles → Agents → Analytics

04

Deployment and gateway

Docker and Kubernetes deployment behind an API management gateway, with API authentication, IP restrictions, a Redis cache and blob storage for recordings and assets.

Gateway → Auth → Services → Cache / Storage

05

Virtual try-on

Garment try-on and face makeup try-on, built as computer vision pipelines at a generative AI startup.

Photo → Vision model → Composite

06

Text-to-3D and image-to-3D

Generative pipelines that turn a prompt or a single image into a 3D asset.

Prompt or image → Generation → 3D asset

Practice

The model is one component. I build the rest of the system around it.

  • Realtime voice

    Speech-to-text, LLM and text-to-speech agents, native-audio models, call recording and live handoff to people.

  • Multimodal and vision

    Try-on, image and 3D generation, and the pipelines that move pixels between models.

  • LLM applications

    Chatbots, retrieval over private data, and adaptive products where an LLM drives the experience.

  • Platform and infrastructure

    Kubernetes, API gateways, caching, storage, authentication, access control and multi-tenant data design.

Own product

genaiapplied.com ↗

An AI learning advisor I designed, built and run myself. A voice guide called Iris assesses where you are, then the product builds a learning path around the answer.

  • Voice assessment on Gemini Live
  • FastAPI backend on Postgres, with authentication and verified email sign-in
  • Generated course pages, served as a static site
  • Live in production

Writing

Architecture notes are on the way.

Long-form breakdowns of decisions that held up in production. Leave an email and I will send them as they are published.

About

Full-stack, then machine learning, then 3D and vision, now realtime voice in production.

I started as a freelance full-stack developer straight out of a BTech. A year in I moved into data science, first classical machine learning and then deep learning, building models for clients who cared whether it worked on their data.

In 2023 I joined a startup working on 3D generative AI and computer vision. Since 2025 I have been building production voice AI: agent architecture, Kubernetes deployment behind an API gateway, Redis-backed state, multi-tenant data and live human handoff.

Let's build what has to stay up.

Contract work, remote roles and technical advisory. Based in India at UTC+5:30, which overlaps European mornings and US evenings.
