Roberto Amaral
@robertoamaral
I build scalable marketplaces, booking systems, and automation products from MVP to production.
BrazilWhat I'm looking for
I've built Appoint from scratch: a complete service marketplace with provider discovery, booking, scheduling, payments, and end-to-end UX designed for user acquisition.
At Omni, I deliver production-ready features used in real business operations. I've resolved concurrency issues affecting multi-user pricing updates, improved order-flow reliability and status management, and built scalable frontend architecture.
Previously at Arcca, I built restaurant-management systems for food chains and logistics operations, covering orders, inventory, and logistics flows with Python, Django, Nuxt.js, and PostgreSQL.
I also build automation tools such as an invoice system that generates PDFs from payment events and stores them in AWS S3, reducing manual operational work. I enjoy turning complex requirements into reliable, high-performing products with strong ownership and fast execution.
