I design and build websites and web apps. Both halves, one person, one invoice. ⭐ React, Next.js, Node.js/Express, Firebase, Supabase, TypeScript, Tailwind ⭐ Design too: brand identity, logos, UI. Not a template with your logo dropped in ⭐ AI chatbots that answer from your own documents (RAG, OpenAI + LangChain) ⭐ Cambridge C1 Advanced, Grade A. Fluent English, native Spanish ⭐ Bolivia, GMT-4. Full workday overlap with US clients Most developers hand you a working site that looks like every other site. Most designers hand you a beautiful mockup nobody can build. Hiring both costs double and they blame each other when something breaks. I do the design and the build, so you get one person who's accountable for how it looks and whether it works. 𝗪𝗵𝗮𝘁 𝗜 𝗱𝗼 1. Marketing sites and landing pages Next.js and React, fast, responsive, built for SEO. If you don't have branding yet, I can do that first: logo, color palette, type system, the full spec. 2. Web applications Dashboards, admin panels, client portals, booking and registration flows. Firebase or Supabase back end with auth, file storage, and security rules written properly. 3. AI chatbots on your documents (RAG) I built a document management platform for a law firm with an assistant that answers questions about their case files: role-based access for three user types, document search, integrated calendar, and a chatbot grounded in the firm's own records. A bot that invents answers is worse than no bot, so retrieval quality is where the work goes. 4. Fixing what someone else left behind Bug fixes on React and Firebase codebases. Half-finished builds that need someone to actually close them out. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I ask the scoping questions before writing code, not halfway through. Updates in plain language. Every delivery includes a short summary of what changed and why, so your codebase still makes sense after I'm gone. Message me with what you're building. I reply fast.
