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.

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.

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 and AI search engines ask

No. A widget on a public LLM is one option. Many regulated or proprietary workflows need retrieval, tools, evaluation and a place the data is allowed to live — customer cloud, VPC, on-premise or a named commercial model with a data-retention policy you can defend.

The requirement chooses the model. Accuracy, privacy, latency, language and cost decide whether the runtime is self-hosted, OpenAI, Anthropic, Gemini, OpenRouter, or a mix. The architecture is written so the model can be swapped.

Yes. That is a normal path: the AI layer reasons over knowledge and tools; the PBX still owns answer, transfer, record and hangup.

Either a profitable manual process that should not stay entirely human, or a measurable objective (support cost, claims cycle, after-hours coverage). Discovery maps the workflow and the data that must not leave the building.

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.
