I'm Alejandro, a full-stack developer and IT consultant based in Miami. Smaller businesses come to me when they've outgrown templates, want to cut recurring software costs, or need something built that doesn't exist yet. Larger companies bring me in for the harder problems: integrating systems that don't talk to each other, building custom internal apps, wiring up APIs, and the kind of hands-on IT work that has no fixed playbook. I work across React and React Native interfaces, Hono and Express services on Cloudflare Workers or VPS, and the databases, CDNs, and self-hosted infrastructure that tie it all together.
Work Experience

Technical Skills
Systems Integration & APIsConnecting CRMs, ERPs, payment processors, and third-party APIs so tools that were never meant to talk now share data reliably. Webhooks, scheduled syncs, and middleware that eliminate double data entry and keep systems in sync, with proper error handling, retries, and logging.
Custom Internal Apps & AutomationReplacing spreadsheets and manual workflows with internal dashboards, admin tools, and automations that cut repetitive work and human error. Built around how a team actually operates, with the reporting and access controls a growing company needs.
IT Consulting & Solution ArchitectureAssessing existing systems, advising build-vs-buy, scoping requirements, and architecting solutions for companies of any size. Vendor-neutral recommendations focused on what solves the problem and what it will cost to run, not on selling a particular stack.
Modern Web FrameworksChoosing the right tool per project: Next.js 14/15 (App Router, Server Components, Server Actions) when full-stack SSR helps, Vite + React Router for fast SPAs, and vanilla HTML/CSS/JS with GSAP or Lenis when a framework would be overkill. React 18/19 across the board with streaming SSR, useOptimistic, and modern patterns.
React Native & MobileCross-platform mobile apps with React Native 0.81 and Expo SDK 54. Native module integration, deep linking, Supabase + PostgreSQL with PostGIS for geospatial features, MapLibre for interactive maps, and full App Store and Play Store delivery pipelines.
Cloudflare Workers & HonoServerless edge APIs with Cloudflare Workers and the Hono framework. Building multi-tenant services, KV caching, D1 (SQLite) and R2 integration, scheduled cron jobs, and dual-runtime patterns (Workers + Node) so the same service runs on the edge or a self-hosted VPS without a rewrite.
Email InfrastructureBuilding self-hosted transactional email services with SMTP, AWS SES, and Nodemailer. Implementing connection pooling, retry logic with exponential backoff, and Handlebars template engines for dynamic emails.
TypeScript & Modern JavaScriptFull type safety across the entire stack using TypeScript 5. Creating type-safe API integrations, custom hooks, and component architectures. Advanced patterns including discriminated unions, type guards, and Prisma-generated types.
Tailwind CSS & UI DesignUtility-first styling with Tailwind CSS 3/4, custom design systems, and dark mode implementations. Experience with shadcn/ui, Headless UI, and building accessible, responsive component libraries with proper ARIA labels and keyboard navigation.
Animation & Motion DesignSophisticated animations with Framer Motion 12, including parallax effects, staggered reveals, carousel transitions, and mobile-optimized motion. Performance-conscious animations with GPU acceleration and reduced-motion fallbacks.
Server AdministrationVPS management with systemd, Caddy web server configuration, DNS management, and SSL certificate automation. Building admin dashboards for server operations and redirect rule management.
Headless E-commerceHeadless Shopify implementations using Storefront API with GraphQL queries, Server Actions for cart mutations, and optimistic UI updates. Experience with product catalogs, checkout flows, inventory management, and multilingual commerce experiences.
Multi-Tenant ArchitectureBuilding multi-tenant SaaS platforms with isolated data per client. Implementing API key management, AES-GCM encrypted token storage, tenant provisioning, and subscription-based access control.
State ManagementComprehensive state management using Zustand, TanStack Query (React Query), React Context API, and React 19's useOptimistic hook. Implementing persistent state with localStorage, optimistic updates, and efficient data fetching patterns.
Backend & DatabaseBuilding APIs in whatever runtime fits the job: Hono on Cloudflare Workers, Express on Node, Next.js Route Handlers, and Supabase / PostgREST. Across PostgreSQL with Prisma, Cloudflare D1 (SQLite), and Supabase, with proper indexing, multi-tenant isolation, and session management via NextAuth.js or signed cookies.
Content Management SystemsHeadless CMS integration with Strapi CMS, MDX-based content systems, and dynamic routing. Building flexible content architectures with proper API integrations, image optimization, and SEO-friendly content delivery.
Cloud Storage & CDNsCloud storage integration with Cloudflare R2, AWS S3, and Backblaze B2. Implementing CDN strategies, presigned URLs, and edge image optimization for fast global delivery.
Forms & ValidationComplex form handling with React Hook Form, Zod schema validation, input masking, and international phone number validation. Building multi-step forms, credit applications, and contact systems with real-time validation and error handling.
InternationalizationFull bilingual (English/Spanish) implementations using React Context API, localStorage persistence, and dynamic content switching. SEO optimization with proper hreflang tags, localized metadata, and translation management systems.
Performance & SEOPerformance optimization across framework-native image pipelines (Next.js Image), custom Cloudflare R2 + Workers transforms, code splitting, and lazy loading, with Lighthouse scores in the 90s+. Comprehensive SEO: dynamic sitemaps, Open Graph tags, structured data (JSON-LD), hreflang, and proper metadata management.
Build Tools & DeploymentShipping to Cloudflare Pages, Cloudflare Workers, Vercel, and self-hosted VPS via Wrangler, systemd, and Caddy. Modern build tooling with Vite, Turbopack, and React Router, plus environment configuration, CI/CD pipelines, and production builds with proper code splitting and tree shaking.
PDF Generation & Document ProcessingClient-side PDF generation with jsPDF and jspdf-autotable for session reports, shipping labels, and branded documents. Custom layouts, table formatting, and multi-page document handling.
