AI engineering in 2026 is no longer about picking a model — it's about wiring real systems against real data with audit-grade observability and compliance-grade security. UseAIEasily ships six service lines from Budapest covering the full production stack: AI agent development with LangGraph and CrewAI, retrieval-augmented generation (RAG) on Pinecone / Qdrant / pgvector, LLM fine-tuning and distillation, custom AI development, AI strategy consulting, and AI security audits against OWASP LLM Top-10 threats. Every line uses the same five-step delivery flow: scoping call, written SoW, build sprints with weekly demos, production hardening, 30-day warranty.
We chose this six-service surface because it's what an EU mid-market or enterprise team actually buys in a 12-month window. A typical engagement starts with a Maturity Assessment workshop (€2,500), follows with one or two concrete builds (€5,000–€25,000 each), and then either rolls into an Embedded retainer (€8,000+/month) or hands off entirely to your team. We don't do dashboards-as-a-service. We don't do retainers without code shipping. We don't do strategy decks that recommend hiring more strategists.
Behind every service is the same engineering bench: senior IC's with 6+ years building production systems before LLMs were viable, EITCA/AI-credentialed by the European IT Certification Institute, working in Budapest's CET timezone with overlap into UK / DACH / US-East workdays. We've shipped 30+ production AI systems for clients across Hungary (FinPálya, Dr. Horváth és Társai, NovaLeads, Medisync), DACH, the UK, and US, and every code repository, prompt file, eval dataset, and fine-tuned weight transfers to the client on day one of go-live. No reseller agreements, no model licensing tail, no offshore handover risk.
AI agents · multi-agent systems
LangGraph, CrewAI, OpenAI Assistants, MCP. Tool-use, planner-executor, supervisor patterns. Cost limits + audit logs + human-in-the-loop gates baked in.
