I'm Luis Villarreal, a full-stack software architect. I design and develop web platforms, applications and AI-powered automations for companies in Mexico, from the initial idea to production, with secure, carefully crafted interfaces and an architecture focused on robustness and scalability.
Software that streamlines operations, reduces manual data entry and provides reliable information for decision-making.
Multi-tenant systems with roles, permissions, subscriptions and admin panels, ready to be offered commercially or rolled out across branches.
Browser-installable apps that work offline to record visits, inspections and evidence, with PDF reports.
Agents and workflows that process documents, validate payments and handle WhatsApp conversations, freeing your team from repetitive tasks.
Sales, operations and compliance dashboards connected to your data sources, so decisions rest on reliable, up-to-date information.
Fast, search-optimized websites with forms, quote builders and content your team can update on its own.
I integrate ERPs, banks, WhatsApp and existing systems, and migrate Excel- or macro-based processes to reliable, maintainable web applications.
A selection of real projects, presented as white-label case studies to protect each client’s confidentiality.
Offline-first PWA for field supervisors to log in-store coaching visits, sign commitments and produce PDF records, even with no signal.
SaaS to track environmental, health and safety permits, licenses and obligations, with expiry alerts and role-based access.
HR platform with AI-assisted training, WhatsApp recruiting campaigns and surveys, and KPI dashboards per company.
PWA to sell tickets, validate SPEI bank transfers and read receipts with AI, with customer credit balances and oversell control.
