Database Integration: Manage and automate data flows specifically using Supabase (PostgreSQL). Web Scraping: Develop robust scraping workflows to extract and process data from various web sources. Testing & Validation: Conduct rigorous testing to ensure 100% data accuracy and workflow reliability before deployment. Stakeholder Collaboration: Join requirement-gathering sessions to provide technical feasibility insights and refine project scopes. Technical Requirements & Skills Expert n8n Proficiency: Mastery of n8n Cloud, including custom JavaScript functions, complex merges, error-trigger workflows, and API authentication (OAuth2, Header Auth, etc.). Advanced Web Technologies: Deep understanding of JSON structures, RESTful APIs, Webhooks, and HTML/CSS selectors for scraping. Database Mastery: Expert-level experience with Supabase/PostgreSQL (writing queries, upserting data, and managing relational structures via n8n). Marketing Stack Knowledge: Proven experience automating tools like HubSpot, Salesforce, Google Ads, Meta Ads, and various SEO/SEM APIs. Data Quality: Experience in building "human-in-the-loop" validation steps and automated data cleaning/enrichment logic.
