Relevance

Why this case matters

This framing makes the decision signal explicit: impact, proof, fit, and AI / delivery relevance for hiring or collaboration.

System impact

Built an AI-powered matching platform from 0 to 1 and combined product, technology, and team design inside an early-stage startup.

AI / delivery relevance

Put AI into the product core early instead of treating it as a thin prompt layer on top.

Case context

Overview

Smartjobr started as an AI-powered freelancer matching platform that had to move from first product model to real delivery. I connected matching logic, technical architecture, and team building in an early-stage startup with fast learning loops, product-market fit work, and direct delivery pressure.

The platform uses k-Means algorithm and NLP for matching between freelancers and projects. Next.js/PWA, AWS infrastructure, and automated BI dashboards connected product usage, technical foundation, and data-informed decisions.
