Overview: GenAI Engineering Services in Le Marais

Beyond the demo, for Le Marais teams

I build the evaluation harness, guardrails and monitoring alongside the feature itself, so quality doesn't silently regress after launch. Anyone can wire up an API call — shipping something reliable, cost-aware and safe under real user load from Le Marais is a different job.

What's included

Prompt and pipeline architecture

Structured prompt design, function calling and multi-step orchestration built to hold up under real Le Marais user traffic, not just a clean demo.

Architecture components

• Function calling and tool-use design
• Multi-step agent orchestration where genuinely needed
• Structured output validation

RAG systems

Retrieval-augmented generation built on vector databases, grounding responses in your Le Marais business's actual data instead of relying on model memory alone.

RAG components

• Document ingestion and chunking strategy
• Vector database selection and indexing
• Retrieval quality evaluation

Evaluation suites and guardrails

Automated evals and safety guardrails so quality is measured continuously for your Le Marais deployment, not just checked once before launch.

Cost-aware model routing

Model routing and caching that keeps inference costs sane as usage scales for Le Marais businesses.

How the engagement runs

Process

Scoping & architecture

We define the exact use case, failure modes and success metrics before writing a single prompt for your Le Marais product.

Build & evaluation

The feature and its evaluation harness are built together, not bolted on afterward.

Launch & monitoring

Production monitoring catches quality regressions in your Le Marais deployment before users do.

Who this is for

Product teams shipping AI features

Le Marais teams that need an AI feature to actually hold up in production, not just impress in a demo.

Engineering teams needing a specialist

Le Marais businesses that want a GenAI specialist to plug into an existing team rather than own the whole build.

Tools & technology

Model providers

LLM platforms

OpenAI, Anthropic (Claude), and open-source models via Together or self-hosted

Chosen per use case for your Le Marais deployment — cost, latency and quality all factor in.

Note

Vector databases and orchestration tooling are selected to fit your Le Marais team's existing stack wherever possible.

Quick answer

GenAI engineering here means building the full production system around a language model — prompt architecture, RAG retrieval, evaluation harness and guardrails — not just wiring up an API call. For a Le Marais business, that's the difference between an AI feature that looks good in a demo and one that stays reliable, cost-aware and safe once real users in Le Marais are hitting it every day.

How this compares to a no-code AI wrapper tool

• No-code AI wrappers give your Le Marais business a generic prompt box; this builds structured pipelines with function calling, multi-step orchestration and validated outputs tuned to your actual use case.
• Wrapper tools rarely ground answers in your own data; RAG systems here index your Le Marais business's actual documents in a vector database so responses aren't relying on model memory alone.
• No-code tools have no evaluation layer; this ships automated evals and safety guardrails so quality for your Le Marais deployment is measured continuously, not just eyeballed once.
• Wrapper tools bill per generic call with no cost controls; model routing and caching here keeps inference costs sane as usage scales for Le Marais businesses.

Why Le Marais teams choose Deepak Suhag

Production LLM pipelines, RAG systems and evals that hold up past the demo — built by someone who ships and monitors, not just prototypes.
