Hi, I'm Joseph Gitonga

Based in Nairobi, I'm remote-first with 7 years of experience working with distributed teams. I consult with founders, operators, and enterprise teams who want to ship AI-enabled software without the drag of building a large engineering department. You might know me as Jay Kiharani elsewhere on the internet.

Over the past 9 years I've helped launch insurance portals, accounting automations, and customer-facing products that blend modern web engineering with trusted AI platforms like OpenAI, Anthropic, and Google Gemini. My role flexes from architect and product strategist to engineer and coach - whatever gets your initiative into the hands of customers faster.
