Senior Full-Stack Developer | Product, automation, and internal systems
I build complete web products: frontend, backend, database, deployment, and production-ready integrations.
I'm Carlos Rodriguez, a senior full-stack developer with experience shipping real applications for operations, sales, ecommerce, events, CRM/ERP, and automation. I work from architecture to production with business judgment and full technical ownership.
Available for full-time, remote, or hybrid opportunities.
Based in Mexico. I work with product, operations, sales, and leadership teams.
Professional profile
Senior developer with full product ownership.
My edge is that I do not just build screens or endpoints: I understand the operational process, business goal, and real constraints inside a company. I have worked in logistics, supply chain, business development, and IT infrastructure, and I now build production systems: mobile apps, corporate sites, ecommerce, CRM/ERP, dashboards, reports, automation, and integrations with AI, email, WhatsApp, and external APIs.
Strong judgment for modernizing legacy systems and migrating modules without stopping daily operations.
Ability to speak with leadership, sales, operations, and end users to turn ambiguous needs into usable software.
