Software that sells — built for your operation.

Cross-platform Flutter apps, AI-powered WhatsApp bots and backoffice systems built with the same rigor we apply to our own SaaS products. A small, focused software shop that talks directly with the decision maker.

● 2 own SaaS products in production ● 6+ years on the market ● Brazil + LATAM

Three pillars. One quality bar.

Hens specializes in three things — and says "no" to everything that doesn't fit. That's how we make sure every delivery is best-in-class.

Flutter Apps

Cross-platform apps (iOS + Android + web) with clean architecture, tests, CI/CD and a focus on performance. From MVP to apps in production with thousands of users.

  • Clean architecture + Riverpod
  • Firebase, Supabase or your own backend
  • Play Store and App Store publishing
  • Ongoing maintenance

AI WhatsApp Bots

Customer service, sales and assistant bots that understand audio, images and text via the official WhatsApp Business API. Integration with Gemini, Claude or GPT. In production since 2024.

  • Official WhatsApp Business Platform
  • Audio, image and text powered by AI
  • Integration with your CRM/database
  • Admin dashboard included

Backoffice Systems

Admin panels, custom ERPs, management dashboards and internal tools that move your operation off Excel and onto real-time data.

  • Dashboards and reporting
  • User, role and audit management
  • External API integrations
  • Cloud deployment (AWS, GCP, Cloudflare)

Our own products and client cases.

Hens Desenvolvimento de Software is a lean shop — no middle layers between you and the people writing the code. We work with everyone from solo founders with their first idea to companies that need to ship faster without sacrificing quality.

Our edge: we run our own products in production. That means we know every WhatsApp Business pitfall, every Firebase bottleneck, every architectural decision that bites you later — because we've already lived through them.

When you hire Hens, you talk directly with the people who understand both the business and the code. No middle PM, no agency, no hidden outsourcing.
