Decathlon Turkey — three platforms

Three engagements for Decathlon, all on serverless AWS — side projects built alongside my full-time role, as most of my freelance work was:

1. Spending Survey App (2018) — an in-store app used across Turkey, Tunisia, and Morocco. Android client, serverless Node.js backend, Aurora MySQL.
2. Customs Pipeline (2019) — a serverless data pipeline (Lambda, S3, SQS) with a Flutter Web dashboard for statistics and analysis.
3. HR Platform (2020) — a React/TypeScript staff panel, a Gatsby candidate site, and a serverless backend.

An enterprise client that came back three times — the strongest kind of reference.
