AI agents & automations
The full AI stack under one roof. LLM integration (Claude, GPT, open models), multi-step agents, autonomous workflows, RAG pipelines (ingestion, embeddings, hybrid search, evaluation), prompt engineering, tool use, structured outputs, fine-tuning, and evals. For support triage, document pipelines, internal ops, and anything else you want an agent doing instead of a person. - 02
Landing pages
High-conversion marketing sites with distinctive design, fast load times, and motion that serves the copy instead of fighting it. - 03
