I am looking for a developer who can support me with selected technical integration tasks, including:

n8n workflows and automation architecture Supabase / PostgreSQL REST API integrations Webhooks OAuth2 authentication JSON data handling JavaScript / TypeScript GitHub Bonus experience: Shopify API TikTok Shop API OpenAI API
