Core capabilities

Six pillars of modern AI engineering.

LLM Applications

Customer-facing chatbots, copilots, content tools and assistants — built on the right model for the job (GPT, Claude, Gemini, Llama).

RAG & Knowledge Systems

Connect LLMs to your data — retrieval-augmented generation with hybrid search, reranking, and citation-grade answers.

AI Agents & Automation

Multi-step agents that browse, code, call tools and complete real work — LangGraph, CrewAI, AutoGen, custom orchestration.

Private & On-Prem LLMs

Self-hosted Llama/Mistral/Qwen on your infrastructure. Full data control, no third-party API spend, SOC2-friendly.

MLOps & Evaluation

Continuous evals, observability, guardrails, prompt versioning and CI for AI systems — so models stay reliable in production.

Computer Vision & Multimodal

Image, video and document intelligence. Detection, segmentation, OCR, generative imagery, vision-language models.

The full stack

Every layer of an AI system.

Modern AI is rarely one model — it's models, retrieval, evals, infra, guardrails, and UX working together. We build all of it.
