Samuel Leal / Lealflow

I build web products that ship fast and still feel sharp.

From internal tools to client-facing platforms, I turn messy requirements into reliable products with clean UX, strong logic and fast delivery.

See selected workStart a conversation

Senior execution across product logic, UX flows and delivery.

Fast MVPs, internal tools and automation-heavy systems.

Comfortable moving between Bubble, APIs and custom front-end.

Bubble Developer

Growth app for a Brazilian real estate agency to expand broker reach, manage listings, and add value to the agency ecosystem.

Shipped a dedicated product layer around the agency's existing system.

  • Created a separate app aimed at acquisition, property management and network expansion.
  • The delivered version later changed hands, so the original product is no longer live as shipped.
