AI Agent (Tool-Using)
Multi-step reasoning with tool calls, LangGraph under the hood. The part everyone skips is evaluation; without a test set it's guesswork, so the harness gets built in.

AI Voice Agent / Outbound Calls
ASR, LLM dialog and lifelike TTS chained together. For outbound calling, settle local compliance first — we build and integrate, we don't advise on the legal side.

LLM Fine-Tuning (LoRA / Full)

Computer Vision
Recognition, detection, OCR, industrial quality control. We train the model and hand you an API. On factory floors, sample volume and lighting set the ceiling, so we check both first.
