Promise Ekoriko
Founder & Principal Engineer at Prodevel Limited
Fifteen years shipping production software for UK startups and universities. Now focused on fractional CTO work and rescuing AI-generated codebases that break in production.
About
Promise Ekoriko is the founder of Prodevel, a London software consultancy that helps founders build, fix, and lead technology without hiring a full-time CTO on day one.
Over 15 years he has led delivery on 100+ projects — from pre-seed MVPs to live platforms used by universities and growing companies. He still writes production code and reviews every engagement personally.
Today his practice centres on two lanes: fractional CTO leadership for non-technical founders, and AI code rescue for vibe-coded apps that fail once real users arrive.
