Ricardo Arroyo
@ricardoarroyo
I build end-to-end web applications and rapid MVPs for operationally complex businesses.
What I'm looking for
I built TrazAPI at ISCorporación end-to-end: a production operations platform for beekeeping producers, from frontend and backend to database design and AWS deployment.
Using Next.js, React, TypeScript, Python, FastAPI, and PostgreSQL, I delivered hive and inventory management, treatment histories, low-stock alerts, financial tracking, reminders, search, exports, JWT authentication, QR codes, and PWA support. I also served as the main client contact, turning business needs into functional requirements and coordinating rollout timelines.
My background in CRM, scheduling, inventory, and bilingual client service helps me build practical tools around real workflows. I'm currently growing a freelance practice focused on rapid MVP and web application development.
