Full-Stack Developer, Full-Time, Blueworks CRM

Who we are: My partner (from Ukraine) and I started a window cleaning business in the US. We needed better software to run it, so we built our own. That became blueworks.app, a field service CRM (scheduling, quotes, invoicing, SMS/voice, payments) for window cleaning, landscaping, and similar businesses. Today 270+ active businesses are subscribed and we're growing fast. https://blueworks.app/ The app was originally built solo, AI-first ("vibe coded"), and it works and works pretty well, recently we started working with a team of developers. Stack: React 18 + TypeScript, Node.js/Express, PostgreSQL (Drizzle), Tailwind + shadcn/ui, Capacitor (iOS/Android), Twilio, Stripe.
