AI Architect, Private & Domain-Specific AI

Turn proprietary knowledge, processes and domain expertise into production AI, without requiring sensitive business data to leave a controlled environment.

Private / VPC / on-premDomain RAGAI agentsLLM servingPyTorch / HFOpenAI · Claude · Gemini

I work with organizations that have valuable internal data, specialized workflows or regulated operations and want to build AI around the business, not bolt another generic chatbot onto a public model.

For the broader AI/data family (RAG pipelines, GraphRAG, events, multi-model routing and observability), see AI, Data & Automation Engineering.

The practice combines AI architecture, software engineering, LLMs, data engineering and domain-specific business logic. Delivery is the same path as the telecom work: discovery → architecture → prototype → production → scale. Remote from Delhi, worldwide. NDAs are normal.

What I build

Private & self-hosted AI

Inference inside a customer cloud, VPC, on-premise stack or another controlled environment.

Domain-specific AI

Terminology, workflows, policies and operational data of that company, not a generic assistant.

AI agents

Reason over business information, call tools/APIs, run workflows and hand off when confidence drops.

RAG & knowledge systems

Retrieval over documents, databases, knowledge bases, call records and policies with access control.

Custom AI/ML

Model selection, fine-tuning, evaluation, inference optimization and domain ML where an LLM is the wrong tool.

AI infrastructure

Serving, pipelines, vector stores, observability, security and the deploy path that operations can own.

AI + systems of record

CRM, ERP, PBX/CCaaS, healthcare and finance systems, SaaS APIs and internal apps.

Multi-model routing

Open-source and commercial models, OpenAI, Anthropic, Gemini, OpenRouter, chosen per job, not per fashion.

Technology

ML / application: PyTorch, TensorFlow, Hugging Face, LangChain, embeddings, structured outputs, tool calling. Serving and data: vector search, evaluation harnesses, Linux/Docker, AWS, GCP and Azure when the customer already lives there.

Where this is the right hire

Healthcare, pharma, insurance, financial services, government, telecom/VoIP, legal, manufacturing, product companies, and SMBs whose advantage is internal process, not a public knowledge cutoff.

Sensitive information should not automatically go to a third-party AI service. The first reply is whether the job is a retrieval problem, an agent problem, a voice problem, or a process that should stay a spreadsheet for another quarter.

FAQ

Questions buyers ask before hiring

Direct answers on scope, stack, rescue vs build, and how to start, structured for search and AI summaries.

Direct answers on scope, stack, rescue vs build, and how to start, structured for search and AI summaries.

Consulting produces decision records, diagrams and risk lists you can hand to any team. Development includes the same clarity plus implementation, tests and production cutover.

Yes. Reviews cover tenant leakage, trunk security, recording paths and whether the gap is configuration or product architecture.

Yes. Fractional blocks suit teams that need senior telecom review without a full-time hire.

We reproduce the failure, capture traces, patch or reconfigure with rollback, then document runbooks so the issue does not return silently.

Production agents need barge-in, latency budgets, tool-calling into CRM/ERP, policy gates and observability. The LLM sits outside call control; Asterisk/FreeSWITCH still owns media and failover.

It depends on tenancy, data residency and whether voice is the product or a channel. We compare build vs buy in the first reply; see Vapi vs Retell framing.

Share the current stack (PBX, CRM, cloud), the failure or goal in one paragraph, peak call volume, carriers, and any deadline. Screenshots, a pcap, or a short Loom beat a 40-page RFP. Use the project brief or email hello@unifiedpbx.in.

Yes. Delivery is remote-first from Delhi with scheduled overlap for EU, UK, US and APAC stand-ups. Production changes use written runbooks, rollback steps and agreed maintenance windows.

Yes. Many engagements begin with a 1–2 week SIP trace review, tenant-isolation audit, or architecture assessment. If the fit is good, scope expands from evidence, not from a generic sales deck.

Founders, CTOs, telecom leads, MSPs and product teams building or fixing UCaaS, CCaaS, CRM+voice, AI voice, or vertical SaaS, not buyers who only need seats on a mass-market suite.

Need this built?

Send the current architecture, call volume, carriers and the workflow you need to automate or productize. Discovery can start from a broken PBX or a blank product brief.

Architecture first. Then production.
