Startups shipping their first AI feature, scale-ups hardening one for production, and enterprise teams that need senior hands on an agentic/RAG/voice build. If "make this reliable, fast, and cost-sane" is the problem, that's the work.
What I Help With
Hands-on engineering, plus the architecture judgment behind it
Agentic AI & LangGraph
Design and build production LLM agents — orchestration, tools/MCP, memory, guardrails, verifiers, evals, and observability that hold up with real users.
RAG pipelines
Retrieval that actually grounds answers: chunking, embeddings, pgvector, hybrid search, semantic caching, and retrieval evals you can measure.
Voice AI
Realtime voice agents on OpenAI Realtime + WebRTC — sub-1.5s latency, barge-in, and cost engineering, drawn from shipping a live voice tutor.
AI architecture & design review
Bring your in-progress system; get a focused audit of orchestration, retrieval, evals, cost, and reliability with a prioritised action list.
Fractional CTO
Part-time engineering leadership for AI-first products: strategy, architecture, hiring, and keeping the build on track.
Embedded & due diligence
Work alongside your team a few days a week, or assess an AI product/team for investors and acquirers.
Engagement Models
Shaped to the problem and your stage
Project
Fixed scope, clear deliverable.
- Ship a defined agent/RAG/voice build
- Milestones and a working system
- Handover + docs
Embedded / Retainer
Ongoing senior capacity.
- Set days per week with your team
- Architecture + hands-on code
- Flexible month to month
Advisory / Fractional CTO
Leadership without a full-time hire.
- Strategy, architecture, hiring
- Design reviews and unblocking
- Investor/board-ready clarity
10+ years shipping production systems — Amazon (Payments), Agoda, and CoinSwitch (scaled 600K → 10M users) — and now building Yuvan, a live voice-first AI tutor on LangGraph, RAG, and OpenAI Realtime. You get senior engineering judgment grounded in systems that actually run.
Frequently Asked Questions
What kind of AI consulting do you offer?
Hands-on AI engineering — building agentic systems (LangGraph), RAG, and voice AI — plus architecture and design reviews, Fractional CTO, and embedded support. The focus is shipping reliable systems, not slide decks.
Do you build, or only advise?
Both. Most engagements are hands-on, but advisory-only (reviews, Fractional CTO, due diligence) is available when that's what you need.
What engagement models are available?
Project-based, retainer/ongoing advisory, embedded a few days a week, or Fractional CTO — whatever fits the problem and your stage.
Are you available remotely and worldwide?
Yes — remote-first across US, European, and Asian time zones, with short-term on-site possible for kickoffs.
