Sobre mí
Hi, I'm Alex! I'm a web developer with 5+ years of experience and a background in Information Systems, and I build with AI every day. I fix bugs, build fast, clean websites (React, Next.js, Supabase, Node.js) and finish apps made with Lovable, Bolt, Cursor, Antigravity or Claude Code. I also create AI mobile apps (React Native), AI chatbots and n8n, Make or Zapier automations, and I design YouTube thumbnails and edit videos and captioned Shorts in DaVinci Resolve and Photoshop. I personally test every delivery. Send me your idea and you'll get an honest plan, fast. Let's build something great!... Lee más

Jul 2023 - Present • 3 yrs 4 mos

Full-stack developer with 5+ years of experience. I build complete websites, apps and AI automations on my own, from design to launch. Background in Information Systems. WEB DEVELOPMENT AND BUG FIXING (React, Next.js, TypeScript, Node.js, Tailwind, Supabase, Firebase, Stripe) - Built a photo studio's booking and payment website end to end, on my own: design, frontend, backend, database, online payments and deployment. It is live and used by real customers. - Built and optimized a SaaS invoicing app and an online store: found and fixed 12 real bugs (hydration, login loop, checkout, failed builds) and raised the Google mobile speed score from 61 to 100. - Built an e-commerce store end to end, from UI to backend: shop, cart and checkout. AI-BUILT APP RESCUE (Lovable, Bolt, Replit, v0, Cursor, Antigravity, Claude Code) - Finish the "last 20%": build errors, blank screens, broken login, data that does not save, failed Vercel or Netlify deploys. - Security fixes: exposed API keys, missing Supabase Row Level Security, weak auth. On a React + Supabase task app I built and audited, I fixed 6 issues and verified 0 rows readable without login and 0 secret keys in the bundle. AI AUTOMATION AND CHATBOTS - n8n and Make workflows that connect forms, email, Google Sheets and CRMs. - AI chatbots with the OpenAI and Claude APIs, plus Telegram and Discord bots. AI MOBILE APPS - Cross-platform apps with React Native/Expo and Flutter, built and tested in Android Studio. VIDEO EDITING AND YOUTUBE THUMBNAILS - Edited videos for creators and teams in DaVinci Resolve and designed thumbnails in Photoshop. - Produced my own promo video with real screen recordings, AI voice-over and captions. HOW I WORK - Reproduce first, then fix, then verify. No guess-and-patch. - AI-assisted, fully human-reviewed: I test and own every line I deliver. - Clean commits and a short note of what changed in every delivery. - Clear scope and price before work starts, fast replies, support after delivery.
