About David

Want to integrate AI intoyour productorautomateyour business processes?

I design and developAI-powered SaaS applications, from idea to production. No POCs that stay in a drawer: products that run with real users.

What sets me apartfrom other developers: 10 years of B2B sales experience before my tech career change. I understand your business challenges, your ROI, and I speak as fluently with your technical team as with your management. I don't deliver code, I deliver measurable value.
