// who, what, why

Elie Serge Tannous

User Journey Specialist and E-Commerce Professional with a decade of customer-experience work across retail, fintech, and grocery. Over the last two years I turned that operational instinct into hands-on AI engineering, shipping Claude- and OpenAI-powered systems on top of full-stack platforms I architect and code myself.

// two pillars, one engineer (click to expand)

// how I work

Operational reality first

If the people who use it can't trust it, the model doesn't matter.

Governance over autonomy

AI proposes, humans confirm. No silent overwrites, ever.

UX for operators

Internal tools deserve the same craft as customer-facing ones.

Read before you write

Read the data and the journey before writing the code.
