Arnaldo Acosta

I build commercial software that supports real business operations, from ERP and Point of Sale platforms to property management, booking, CRM, learning management, and workforce systems.

At Proxima MC, I'm the founder, product architect, and sole developer of an ERP and POS platform used across five retail locations. I built its Laravel, React, and React Native stack, including local-first sales workflows, cloud synchronization, inventory for up to 96,000 products, payments, electronic invoicing, and retail hardware integrations.

For Las Terrazas Resort, I developed and evolved a hotel software ecosystem spanning reservations, payments, guest operations, reporting, and owner revenue distribution. I also built a React booking engine, integrated SynXis, eZee PMS, CyberSource, Mailgun, and WhatsApp workflows, and led a distributed team of three developers.

I've worked directly with owners and operational teams to turn real workflows into reliable software, including LMS, CRM, e-commerce, workforce tracking, IoT, and automation products. I enjoy owning work from discovery and UX/UI through architecture, deployment, support, and long-term product evolution.
