Lead full-stack developer at IncubatorLab.ai who built Shopify Plus systems and a 12-source media performance dashboard.

Italy

Message

At IncubatorLab.ai, I led development and technical direction for PuurSmile, a Shopify Plus store. I introduced a Git-based review and release workflow and led a cleanup of the product catalogue and overlapping page builders.

I designed and built a Media Performance Dashboard that brings data from 12 sources into one analytics platform, replacing a 19-tab spreadsheet and a hand-built weekly deck. It includes data-lineage checks and more than 500 tests.

I also built an AI creative-naming pipeline that proposes structured ad names with evidence for human review. Acceptance rates are tracked by prompt version.

Across my work with Helping Hands in Birmingham Ltd, Affinity Agency, and independent clients through Letrion Labs, I’ve built WordPress and Shopify platforms, Hydrogen storefronts, and internal tools. My projects include an offline-first field reporting app and a WooCommerce catalogue with 35,000 product variants.
