AI systems
Applied AI inside the systems above and for clients: extraction, speech, retrieval and vision, measured against hand-checked answers before anything ships.
in production Document extraction Utility invoices and emissions reports turned into validated JSON for a compliance platform. A self-hosted 8B vision model gets 99.2% of invoice fields right (132 of 133) in 1–2 s per document; measurement tables come out 100% correct from native PDFs. A new document type is a config file, not code. pdf → text or ocr → llm · json schema → validators
in production Meeting transcription Speech-to-text on the company's own hardware, so recordings never leave the building. 5.2× real time on CPU, speaker diarization, and a glossary pulled from the ERP so internal jargon comes out right. audio → whisper → alignment → speakers
in production Operations assistants Supplier purchase orders and payment receipts read from PDFs through an EU-only LLM endpoint. A WhatsApp assistant looks up orders with tool calls, and a person approves every draft before it goes out. pdf → docling → llm → schema check
live Legal retrieval Hybrid BM25 and vector search over Spanish law with reranking and citation checks, scored on 678 questions (recall@10 0.76). Qwen3-Embedding-8B fine-tuned with QLoRA on hard negatives filtered by an LLM judge. query → bm25 + vectors → rerank → cited answer
built Visual inspection Defect detection trained only on good parts, exported to ONNX for edge devices. AUROC ≥ 0.99 on 7 of 12 categories of public industrial benchmarks. camera → patchcore → heatmap → defect class
Also: vision-model bake-offs across Qwen, Gemma and Mistral; ModernBERT fine-tunes for issue triage; coding-agent orchestration with isolated worktrees.
