Senior AI engineer with nearly a decade in data and software, the last ~5 years deep in production AI: LLM systems, AI agents, and applied research. I've shipped AI running at enterprise scale across dozens of countries, and I build AI products end to end.
My deepest production experience is in applied LLM and document AI. As founding data scientist at a document-AI company, I built the core extraction engine from scratch, won a competitive enterprise contract against several established vendors, and scaled it across a global logistics leader's operations in dozens of countries, processing tens of millions of documents a year. I led its move to an LLM-based pipeline with on-prem models and AI agents, replaced rule-based classification with LLM classification, and built an in-house OCR engine that removed a costly third-party dependency. The team grew from 3 to ~90 people, and I'm now Chief Data Scientist.
But I work well beyond any single domain:
• AI agents & agentic systems: I design and ship tool-using agents and multi-step workflows. My own product, Kwiro, is a live, catalog-aware AI sales agent (RAG plus a multi-layer learning memory) published publicly on WordPress
• Production LLM engineering: RAG, structured extraction, fine-tuning, evaluation, and on-prem/self-hosted serving (vLLM, SGLang, speculative decoding, H100) to keep models fast and cost-efficient.
• Applied AI research: independent work on multi-agent architectures, reasoning, and novel algorithm design, including experimentation on hard AGI-style reasoning benchmarks.
• AI software development: complete products built end to end, from backends and APIs to auth, billing, and deployment (Python, full-stack).
• NLP & document AI: extraction, classification, OCR, and sentiment from messy, heterogeneous, real-world data.
I care about AI that actually ships and holds up in production, not just demos. That means accurate, fast, cost-efficient, and maintainable. Whether you need an agent built, an LLM prototype taken to production, a hard problem researched, or an AI product built from scratch, let's talk about what you're building.
