👋 Hi, I'm
Ronald González
Full-Stack Developer
Specialized in Next.js · GraphQL · performance-driven architecture. I build production systems with Redis cache strategies, headless CMS integrations, multi-tenant SaaS logic, and AI pipelines. Automation Engineering student at CUJAE. C1 English (CAE 193/210).
✨ Featured Project
Where Industry 4.0 meets modern software architecture.
2026 · Full-Stack · GraphQL · AI Pipeline
Setpoint
Technical publication platform for Industry 4.0 — PLCs, SCADA, IIoT, OPC-UA — built with a production-grade stack. Redis cache achieves TTFB <50ms on cached routes. Contentful GraphQL via Apollo Client with RSC integration, AI syndication pipeline, role-based auth, and a full admin panel.
- ▹TTFB <50ms on cached routes via Upstash Redis (vs ~400ms cold)
- ▹AI syndication — Contentful webhook → Gemini adapts → Hashnode publishes with canonical URL
- ▹Lighthouse 97/100/100 Accessibility · Best Practices · SEO
- ▹43 tests — Vitest (unit + component) + Playwright E2E
- ▹Full admin panel — comment moderation, syndication controls, logs
📁 Other Projects
Real applications, real bugs, real fixes.
Multi-tenant client management SaaS with role-based access (admin/staff), business-scoped data isolation at the Prisma query level, and AI-powered weekly report generation via Gemini 2.5 Flash with OpenRouter fallback.
Multi-tenant architecture · Optimistic UI updates · Parallel Prisma queries via Promise.all
Real-time industrial sensor monitoring dashboard with LLM-powered anomaly detection. Calls OpenRouter API on every anomaly to generate maintenance recommendations in natural language.
60fps Recharts with memoization · PostgreSQL audit trail · AI weekly report endpoint
Full book-lending platform with RBAC (admin/librarian/member), loan tracking, and full-text search. Production debugging: JWT expiry, connection pool 5xx errors, image delivery via Cloudinary.
60% faster API response via PostgreSQL index optimization · Composite indexes on high-cardinality filters

🧠 Beyond the Code
I'm a 19-year-old Automation Engineering student from Cuba, but my real classroom has been GitHub and the documentation rabbit hole. With 2+ years of daily self-study, I've built 5 production-grade applications — from headless CMS platforms with AI syndication pipelines to multi-tenant SaaS and real-time monitoring dashboards.
My edge? I combine full-stack engineering with systems thinking inherited from Automation. I don't just fix bugs — I find root causes. I don't just ship — I measure. And I communicate everything clearly in C1 English.
When I'm not coding, I'm playing chess, watching anime, or figuring out how to make my internet last longer during blackouts. Resilience is built, not given. 🇨🇺
