KONGO Nancy Emmanuel

Product-minded Fullstack Engineer · Web · Mobile · from idea to production

A self-taught developer turned co-founder, I turn an idea into a product that ships, runs in production and stays maintained. I own the whole chain: design, web & mobile development, deployment, maintenance. My proof: two startups whose entire technical side I led, and systems delivered for e-government, healthcare and e-commerce.

5 years of experience 2 startups co-founded 5+ products in production

How I work

I start from the need, translate it into a technical solution, build, deploy, and stay accountable for keeping it running. A single point of contact for design, front, back, mobile and infra, rather than coordinating five vendors. Priority on quality, documentation and a disciplined use of AI.
