Data Engineer and React Developer Conversion Tracked Landing Pages
Morocco
Arabic, English, French
About me
I build landing pages the way a growth engineer would — with a data layer underneath, not just a design on top.
I specialize in React landing pages instrumented with custom event tracking, PostgreSQL pipelines, and live Streamlit/Power BI dashboards that show exactly why visitors convert — or don't.
▸ SaaS founders: data-backed conversion intelligence
▸ B2B businesses: lead forms wired directly to your database
▸ Data companies: pages that speak to technical buyers
Stack: React · PostgreSQL · Supabase · Python · Streamlit · Power BI
No templates. No guesswork. Let's talk.
