KONGO Nancy Emmanuel
Product-minded Fullstack Engineer, from idea to production · Web · Mobile · DevOps
Profile
A self-taught developer turned co-founder, I turn an idea into a product shipped to production
and kept running. I take end-to-end ownership: design, web and mobile development, deployment,
maintenance. 5 years of experience and two tech startups (Mobembo, Iba Alongi) whose entire
technical side I lead. I have designed, built and deployed demanding business platforms
(healthcare, public administration, document management (DMS), education, finance, e-commerce),
from design through to deployment, both within well-coordinated teams and as the lead developer.
I care about quality, documentation and knowledge transfer (mentoring, disciplined use of
AI in development). Available for fully remote work.
