AI Products That Work in Production — Not Just in a Demo

Most AI prototypes never reach production. They fail on real data, real edge cases, and real security requirements. We build AI products and workflow automation engineered for your data, your compliance model, and your operational reality.

CORE CAPABILITIES

What We Build on AI Engagements

Enterprise LLM Integration & Custom AI Assistants

  • GPT-4, Claude, Mistral, Llama — model selection based on data privacy, latency, and cost requirements
  • Custom system prompt engineering and fine-tuning pipeline design
  • Conversation memory management: session context, user history, long-term knowledge
  • Function calling and tool use — AI agents that take real actions in your systems

RAG Pipelines (Retrieval-Augmented Generation)

  • Document ingestion: PDFs, DOCX, HTML, databases, structured and unstructured sources
  • Vector database integration: Pinecone, Weaviate, pgvector, Qdrant
  • Hybrid search: semantic similarity + keyword BM25 for precision and recall balance
  • Source attribution, confidence scoring, and response grounding

Semantic Search

  • Replace brittle keyword search with intent-aware semantic search across your content or product catalog
  • Multi-language embedding models for global content search
  • Real-time indexing pipelines with change detection
  • Faceted filtering combined with semantic ranking

Intelligent Workflow Automation

  • AI-powered document classification, extraction, and routing
  • Approval workflow automation with AI pre-screening and human-in-the-loop escalation
  • Automated report generation from structured and unstructured data sources
  • Email, Slack, and webhook-based notification intelligence

AI Infrastructure & MLOps

  • Model serving: FastAPI, vLLM, Triton — optimized for throughput and cost
  • Prompt versioning, A/B testing pipelines, and regression test suites for model behavior
  • Cost monitoring dashboards: token usage, model routing analytics, latency tracking
  • Async inference queues for high-volume batch processing

HOW WE WORK

The AI Product Delivery Process

WEEK 1

Data & Use-Case Audit

We assess your data sources, privacy requirements, and automation opportunity. Output: ranked use-case shortlist, data readiness report, and recommended model architecture.

WEEKS 1–3

Proof-of-Concept on Real Data

A functional, deployed PoC on your actual data — not synthetic samples. This is where hallucination rates, latency, and cost-per-query are benchmarked against real conditions.

WEEKS 3–10+

Production Pipeline Build

Full pipeline engineering: ingestion, vectorization, retrieval, generation, caching, monitoring, and API layer. Every component built for production load, not demo conditions.

POST-BUILD

Integration, Testing & Handover

Integration into your existing product or internal systems. Load testing, accuracy benchmarking, and full documentation. Your team inherits the system with complete operational runbooks.

WHY HARDENED SOFT

What Every AI Engagement Includes

Our AI builds are production systems, not demos. No data sent to third-party models without your explicit consent. Every pipeline is observable, auditable, and maintainable by your own team. And you receive 100% code ownership — including all prompts, pipelines, vector stores, and fine-tuning configurations.
FAQ

Common Questions About AI Development

Do you use OpenAI or open-source models?

Both. We select the model based on your data privacy requirements, latency targets, and budget. We've deployed on OpenAI, Anthropic, AWS Bedrock, Azure OpenAI, and self-hosted Llama/Mistral depending on the compliance environment.

How do you prevent sensitive company data from being used to train public models?

We configure API calls with zero data retention options, use private deployment for sensitive workloads, and never send raw company data to fine-tuning endpoints without explicit scoping.

What's the typical cost of running an LLM pipeline in production?

Highly variable. We build cost monitoring dashboards into every deployment and implement semantic caching and model routing to minimize per-query costs. We'll give you a cost-per-query estimate before build begins.

Can you improve an AI feature we've already built?

Yes. We audit the existing pipeline, identify accuracy, latency, and cost problems, and propose a remediation plan. This is often faster than a full rebuild.

How do you handle AI accuracy and hallucinations in critical workflows?

We design human-in-the-loop checkpoints for high-stakes decisions, implement confidence scoring to route uncertain answers for review, and use source-grounded RAG to minimize unsupported generation.
