Yassine D.

Senior Full Stack | API & Data Integrations | BigQuery, Make, SQL

⚙️ I build API integrations, data pipelines and automations, and I fix the ones that have already stopped. ━━━━━━━━━━━━━━━━━━━━ 🔗 INTEGRATIONS Xero · Salesforce · Okta · Telnyx · ActiveCampaign · Shopify · WooCommerce · Google (Sheets, Places, Ads, Cloud) · Amazon SP-API ▸ Recent: a Xero to SQL Server integration in C#, handling contact export and invoice creation with OAuth token refresh, tested end to end against a live Xero company before it went near production data. ━━━━━━━━━━━━━━━━━━━━ 📊 DATA AND REPORTING BigQuery · Looker Studio · Power BI · Tableau · SQL Server · Postgres · Azure Data Factory · Excel · VBA ▸ Recent: an App Store and Google Play revenue pipeline into BigQuery. Play came in through the native transfer. Apple has no equivalent, so I wrote a Cloud Function to pull, normalise and land the reports in the same dataset, with a Looker Studio dashboard on top. ━━━━━━━━━━━━━━━━━━━━ 🤖 AUTOMATION Make · Zapier · Power Automate · n8n · Airtable · Bubble ▸ Including the awkward parts: webhooks that need a real endpoint behind them, and scenarios that break silently when a connected app changes its API. ━━━━━━━━━━━━━━━━━━━━ 🛠️ RESCUE WORK The script that stopped when an API version changed. The database that will not restore. The flow that fails without telling anyone. I am comfortable inheriting someone else's code, and I will tell you if I think it should be rewritten rather than patched. ━━━━━━━━━━━━━━━━━━━━ ✅ 180 contracts on Upwork, across integrations, automation, data engineering, Microsoft business systems and web development.
