The technical side — what I've shipped, what I use, and how I think about it.
Experience
Co-founded WiseUtils, which builds AI agents and automations for small businesses in Argentina and LATAM, most of them on WhatsApp. Work spans RAG systems with vector search, Anthropic Claude integrations, retrieval pipelines built per client, and agentic workflows — alongside e-commerce platforms, inventory tools, and conversational interfaces.
Owned frontend web development, building and iterating on key user-facing sections. Contributed to A/B testing, implemented analytics and tracking, and optimized Core Web Vitals. Participated in the gradual migration of selected components from a Vue-based SPA to React and Next.js for performance and SEO.
Web development using React.js, Next.js, Firebase. Collaborated with UX/UI designers on company website and new projects including Hablalo back office.
Developed Wee! Pagos payment app and Wee!pas ticketing app using React and Next.js. Built Recolector mobile app from scratch in React Native.
Projects
Private knowledge platform that turns curated content into a queryable second brain. Captured links and notes are embedded with Voyage AI and stored in Postgres + pgvector; natural-language questions trigger semantic retrieval and are answered by Claude through a purpose-built RAG pipeline. Built as a single Nuxt 3 + TypeScript app on Supabase (auth + Postgres + pgvector), deployed on Vercel.
Private, no-login IELTS Speaking trainer with AI feedback. Practice spoken answers and get instant, structured coaching on fluency, vocabulary, grammar, and pronunciation. Built with Nuxt 4 and Gemini — audio is analyzed in real time and never stored, with only a streak counter kept in the browser.
WhatsApp-first financial companion that turns receipts and freeform Spanish text into structured expense data through a natural-language extraction pipeline (Gemini AI) over a Nuxt + Express stack. Dual modes for collaborative trip splitting and personal tracking.
Construction expense management platform. Site teams log expenses through a natural-language pipeline (Gemini AI) on WhatsApp, and a web dashboard surfaces real-time insights and financial reports for builders and clients.
E-commerce platform for sports jerseys and apparel. Features product catalog, shopping cart, advanced search & filtering, and admin management tools.
Natural language route planner PWA. Users describe their stops by text or voice; Gemini AI extracts, orders, and optimizes them, then opens Google Maps with everything pre-filled. Built as a Nuxt 4 + Express monorepo with server-side AI calls to keep API keys secure.
Platform connecting AC technicians with clients in Argentina/LATAM. Three interconnected domains: technician landing pages, back-office dashboard, and client booking.
TOEFL exam prep app with word completion, reading comprehension, listening exercises, speaking prompts, and writing tasks.
