I build the platform under the product.

I'm Ravi Roy — an AI Platform Engineer & Infrastructure Architect. I design and ship production AI platforms, multi-tenant SaaS, agents, and the orchestration layer behind them — end to end, from Postgres to LLM routing to mobile.

what-i-build

Not websites. Platforms, agents, and infrastructure.

Most of what I build is the hard layer underneath AI products — the orchestration, identity, and multi-tenancy that make them work at scale.

AI Platforms & Orchestration

The runtime that makes AI products possible — routing, fallback, and multi-model architecture across 60+ providers.

  • AI orchestration backend (Mastra)
  • Provider-agnostic model routing
  • Multi-provider architecture
  • Organization-aware AI memory

AI Agents & Voice AI

Agents that use tools and remember context, and voice systems that hold real conversations.

  • Tool-calling agent runtimes
  • Low-latency voice pipelines (STT → LLM → TTS)
  • Interruption / barge-in handling
  • RAG & tenant-scoped memory

Workflow Automation

Node-based pipelines and content distribution that run reliably, async, at scale.

  • Node-based workflow engine
  • Scheduling & async execution
  • Retries & queue processing
  • Multi-channel content distribution

Auth, Identity & Multi-Tenancy

The hard identity layer — solved once, reused everywhere.

  • Multi-tenant orgs & projects
  • RBAC, SSO, passwordless
  • Audit logs & session management
  • Encrypted secret vault

Mobile & Web Products

End-to-end product delivery, from data model to app store.

  • React Native / Expo apps
  • Next.js / React / Vue / Ionic web
  • Production backends (Fastify / Express / NestJS)
  • Hardware / IoT integration

The platforms and products that define what I build — each a real, live system. Real screenshots, real brand, real scale.

ai-infrastructure

The orchestration layer behind the products.

The single most useful thing I build: the infrastructure that makes AI products possible without rebuilding the foundation every time.

60+
model providers routed through one API

provider-agnostic orchestration layer
fallback paths — never locked to one vendor
01

Model routing

Provider-agnostic router with cost-aware selection and automatic fallback across 60+ providers.

02

Multi-model architecture

A single request can fan out or fail over between models — no app changes required.

03

Organization-aware memory

Agent context isolated per tenant. Memory never leaks across organizations.

04

Workflow automation

An orchestration backend that chains models, tools, and steps into reliable workflows.

infrastructure-and-automation

The platforms underneath the products.

Internal infrastructure I've built and run in production — the hard layer other products delegate to. Solved once, correctly, and reused everywhere.

01One API in front of 60+ model providers.

AI Orchestration Platform

A provider-agnostic orchestration layer that routes every AI request across 60+ providers with fallback and cost-aware selection. Apps ask for a capability; the platform decides which model answers — so products are never locked to a single vendor.

  • 60+ AI providers behind one interface
  • Model routing with fallback & cost-aware selection
  • Multi-provider architecture (fan-out / fail-over)
  • AI workflows chaining models + tools
  • Mastra backend (Bun / Hono) runtime
  • Organization-aware AI memory

02Node-based pipelines that run reliably, async, at scale.

Workflow Orchestration Engine

A node-based workflow engine for automating multi-step pipelines — scheduled or event-driven, executed asynchronously with retries and backoff. The substrate behind automations across the platform.

  • Node-based visual workflows
  • Scheduling (cron + event triggers)
  • Asynchronous execution
  • Automatic retries with backoff
  • Multi-step pipelines with branching
  • Durable queue processing

03Publish once, distribute everywhere — on schedule.

Content Distribution Infrastructure

A multi-channel distribution system that schedules, repurposes, and auto-publishes content across social platforms and blogs through OAuth integrations and queue-backed processing.

  • Scheduling & auto-publishing
  • Content repurposing per channel
  • Multi-channel distribution
  • OAuth integrations

Authentication Platform

The org-first identity platform every product delegates to: multi-tenant organizations and projects, RBAC, SSO, passwordless and social login, session management, audit logs, and an encrypted secret vault.

  • Multi-tenant — organizations & projects
  • RBAC (org / role / resource)
  • SSO + passwordless + email OTP
  • Social login
  • Session management
  • Audit logs
