Back to original languageAbout David
Forward Deployed Engineer (FDE) - I turn operational bottlenecks into production AI. Not R&D, not PowerPoints: I integrate with your team, map the real business process, and deliver working software in weeks.
In 5 years, I've delivered over 27 AI and automation projects across more than 17 sectors - construction, real estate, retail, logistics, legal, automotive. That variety is key. Each sector leaves me with a pattern I can reuse in the next.
What I build
- AI Agents and LLM orchestration. Multi-agent systems, RAG, tool-calling, assistants connected to your real stack (ERP, CRM, databases), not demos.
- Document processing with AI. Invoice/delivery note extraction → master data → ERP.
- Backend in Python and API integration — custom APIs, automated workflows, data pipelines.
- Web scraping and data extraction at scale.
- Conversational AI. WhatsApp/web assistants for support, lead generation, and bookings.
- Rapid prototyping. POC → MVP within your infrastructure.
How I work
I identify where you're losing time or money, put a number on it, and build what eliminates it. AI is the capability. Operational ROI is the goal. Process specialist first, AI specialist second.
