Manual prospecting through Google Maps meant searching business by business, copying contact details by hand and losing track of sales follow-up. Synttek Leads Engine replaces that process with a full-stack platform that discovers local businesses through Google Places, enriches them with static scraping and Playwright to find WhatsApp and Instagram, calculates an automatic lead score and organizes everything in a CRM with Kanban and list views. Built with Next.js, TypeScript, Express, PostgreSQL, Supabase, Playwright and Zod, the tool centralizes discovery, prioritization and follow-up in a single reusable workflow. It's an internal tool with no public demo, but it runs in production as Synttek's prospecting engine, replacing a manual, fragmented process with a structured pipeline.
