Neeraj

Voice AI and full-stack engineer · building agentic systems for enterprise.

Shipped an enterprise voice AI platform at IntellifyAI, 1.2s median full-turn latency, multi-tenant on LiveKit and Azure AI Foundry.

Inviting me to speak or mentor at an event?

What I do

Three lanes. Same standard of work.

Production voice systems, agentic backends, and the occasional 1:1 session. Pick the lane, and I'll meet you there.

Voice AI engineering

Production voice agents at 1.2s full-turn latency. Real-time orchestration, telephony, barge-in, multi-tenant isolation, and observability, built for systems that actually answer the phone.

  • 1.2s full-turn latency
  • GDPR-grade isolation
  • Multi-tenant under load

From spec to production

POCs first. Scoping with numbers. Production runtime. Evals before traffic. Team handoff.

AI agents & full-stack

Tool-using agents and RAG pipelines shipped as real products. Eval harnesses, hybrid retrieval, and the full-stack to ship them. TypeScript and Next.js up top, Node.js or Express on the API, Python for the AI/RAG layer.

For students & devs

Want a second pair of eyes on your AI work?

Free 30-minute calls. Bring a real problem and we will dig in.

I ship voice agents enterprises pay for. That means I can tell you which parts of the AI stack actually matter in production, and which tutorials are wasting your weekends.

What we can dig into

  • AI career roadmap: what to build, what to skip, what hiring managers actually look for.
  • Voice agent architecture: latency budgets, eval harnesses, observability, multi-tenant scale.
  • Portfolio and resume teardown: concrete edits, line by line.
  • Whatever you're stuck on. Bring the actual problem.
Free

Not paid. Just a call. If you want deeper ongoing work after, we can talk about it on the call.

For event organisers

Talks from an engineer who actually ships voice AI.

Hackathons, bootcamps, college lectures, industry panels. Based in Delhi, India. Happy to travel across India and worldwide, or join remotely.

On stage with the audience in view.

Most AI talks are slides about demos. Mine come from a production voice platform: ~1.2s median full-turn latency, multi-tenant isolation under load, GDPR-grade. Audiences leave with what the textbooks miss.

  • War stories from shipping enterprise voice agents, not recycled tutorials.
  • Concrete numbers: latency budgets, eval harnesses, tenant isolation tradeoffs.
  • A working engineer who can answer the hard questions in the Q&A.

Got an event in mind?

Share format, audience, and date. I'll get back within a few days.

For founders & companies

Production systems that ship to enterprise, not demos.

Enterprise builds and technical consults for voice AI, AI agents and agentic backends. Sub-second stage latency, GDPR-grade tenant isolation, and the engineering to back it all up.

Just shipped an enterprise voice AI platform: ~1.2s median full-turn latency, ~10 tenants verified isolated under load, GDPR-grade and security-reviewed. Taking a small number of enterprise engagements. Not taking full-time roles.

Just want the basics?

Skip the calendar. Email me, grab the resume, or reach me on LinkedIn.

Free, no commitment. We'll figure out scope and fit on the call.

How I work with teams

Technical consult

Your team is stuck on an AI agent, voice agent or RAG problem: latency, turn-taking, tool calls, evals, multi-tenancy. Book the call and we work through it together. The first call is free, 30 minutes.

Enterprise builds

Large custom AI systems, designed and delivered end to end on contract. LiveKit, Azure AI Foundry, Node.js, FastAPI, Next.js. Sub-second stage latency, tenant isolation, eval harness, observability, handoff docs. Delivered, not demoed.

Team collaboration

I work alongside your engineers to design and ship it with them: architecture, code review and hands-on work on the critical path, so the knowledge stays in your team.
