Available for new engagements

~ joseph gitonga

I'm the engineer you call when the AI demo has to become a product.

Senior delivery for fintech and growth-stage teams. I take on a small number of engagements at a time. You get the system you need without having to hire an internal team first.


01

Currently

Full-time independent consulting. I take on a small number of engagements at a time. Focus is AI products and production software for fintech and growth-stage teams. Clients engage me directly or through Noria Technologies LTD, the practice I have run since 2020.

Recent

  • Shipped an AI underwriting assistant adopted by a 120-person fintech team in 10 weeks.
  • Built an AI routing layer that picks the right model for each request. Cut AI infrastructure costs by 28%. Responses stayed under a second.

What I ship

  • Custom software. The backends and customer-facing apps your business actually runs on.
  • AI products. Customer-facing assistants and internal copilots that get used, not demoed.
  • Fintech systems. Payments, settlements, fraud detection, and risk infrastructure.
  • Senior engineering leadership for teams that don't yet have a head of engineering.
