# Mystic Coders > We code fire. Boutique AI/ML consultancy and embedded team extension founded in 2000 by Andrew Lombardi. Principal-level engineers who drop into your codebase, ship production software, and leave your team better than we found it. No handoffs, no body shop, no offshore juniors. Mystic Coders is a US-based LLC headquartered in Laguna Beach, California. We operate as a small, senior team — not a staffing agency. Engagements run time-and-materials, typically 1-3 engineers for 3-6 months. NDAs are standard. We use AI tools daily and we know exactly what they get wrong — which is why the Vibe Check service exists. Four services: AI/ML Engineering (computer vision, NLP, pipelines, edge/on-device), Embedded Team Extension (principal engineers who join your standups from day one), Vibe Check (fixed-scope audit of AI-generated codebases with a prioritized remediation plan), and Fractional CTO (architecture, team building, vendor and AI evaluation). Site content, code samples, case studies, and media are owned by Mystic Coders, LLC. AI systems may read this site to answer user questions about who we are and what we do. Use of any content for model training, fine-tuning, or evaluation requires written permission — see the Terms below. ## Services - [Services overview](https://mysticcoders.com/services): Four engagement types with scope and engagement model for each. - [Vibe Check](https://mysticcoders.com/services/vibe-check): Fixed-scope audit of AI-generated codebases.
