Moving generative AI from prototype to production reliability

Anyone can build a quick chatbot demo with an API key. Building production AI requires solving hallucinations, enforcing strict output schemas, handling token costs, protecting sensitive enterprise data, and maintaining sub-second latency.

Our AI engineers build practical, grounded AI capabilities: hybrid vector search, context window optimization, automated evaluation harnesses, and human-in-the-loop review workflows.

Applied AI Engineering Capabilities

Specialized capabilities across RAG architectures, model fine-tuning, and production evaluation.

Retrieval-Augmented Generation (RAG)

Building document ingestion pipelines, semantic chunking, vector indexing, and hybrid reranking for accurate retrieval.

Key Deliverables:
pgvector / Pinecone indexing
Hybrid semantic & keyword search
Grounded citation engine

Structured Extraction & Agents

Extracting structured data from unstructured PDFs, emails, and images using function calling and strict Zod schemas.

Key Deliverables:
Function-calling agent workflows
Pydantic data models
Multi-step validation pipelines

Model Evaluation & Benchmarking

Authoring automated test harnesses (Ragas, TruLens) to measure answer relevance, faithfulness, and latency.

Key Deliverables:
Automated evaluation matrices
Gold standard test datasets
Cost & token usage monitoring

AI Product Integration

Connecting LLM capabilities to your existing web and mobile applications with streaming UI responses.

Key Deliverables:
Streaming WebSocket responses
Context window caching
Graceful fallback mechanisms

Privacy-First Architecture and Enterprise Guardrails

Enterprise data must remain private. Our AI engineers ensure your customer data is never used to train public models, implementing PII redaction, role-based document access controls, and zero-retention API endpoints.

Automated PII scrubbing before prompts reach model providers
Role-based document filtering ensuring users only query files they have permission to view
Cost controls with token budgets, semantic caching, and rate limiting
Transparent source citations allowing users to verify AI answers against original documents
