The Library of Babel (Full-Stack Inventory App) Inspired by Jorge Luis Borges’ vision of infinite knowledge, I built a full-stack inventory management app that simulates a digital library system. The backend, powered by FastAPI, handles CRUD operations and persistent data storage in a flat JSON file. The frontend, built with Next.js, TypeScript, and Tailwind CSS offers a parchment-themed interface with real-time counters for unique titles and total volumes. Key features include: - Smart stacking: Adding a book with an existing ISBN increases its quantity. - Gradual vanishing: Titles disappear only when all volumes are removed. - Global search: Filter by title, author, year, or ISBN. - Archival UI: Designed to evoke the feel of Borges’ hexagonal galleries.

Renewable Grid Simulator (Web App for Science and Sustainability) ♻️💚 A real-time simulation of a renewable energy grid, this full-stack web app models the balance between solar, wind, and hydro production against grid consumption. Users adjust input parameters (sunlight hours, wind speed, water flow, and demand) and the system calculates net energy output using physics-based formulas. I chose to focus on renewable ‘green’ energies (solar, wind, and hydro) because they represent the most accessible and impactful pathways toward a sustainable future. Perfect for a science class or as an interactive resource to prepare for Earth Day🪴 (April 22), this project blends technical precision with visual storytelling to make sustainability data engaging and intuitive.

Apex Man is a conceptual e-commerce platform I designed to reimagine the luxury shopping experience using generative AI. It replaces static product catalogs with an intelligent, 24/7 personal concierge. Through LLMs, the system interprets natural language requests based on context, such as "I need a watch for a business dinner", and provides immediate, curated, and shoppable recommendations. The goal is to drive conversion and loyalty through hyper-personalized conversational commerce.

PropertyFlow: Custom Mobile CRM Interface 🏠✨ A concept for a modern, mobile-first CRM for busy real estate professionals. This project showcases a clean, intuitive UI designed to manage the entire property lifecycle from a smartphone. The mockups illustrate secure agent authentication (login screen) and a streamlined "New Listing" form, allowing agents to quickly input crucial data such as property address, client details, pricing, and commission status on the fly. It focuses on reducing friction for data entry on smaller screens.

AI Football Scout Agent: Player Analysis & Tactical Insights The AI Football Scout Agent is an intelligent mobile experience designed to evaluate football players using generative AI, advanced stats, and visual analysis. The agent provides scouting reports, heatmaps, tactical insights, player-to-player comparisons, and market value estimations. Users can chat with the AI to receive personalized recommendations based on play style, metrics, or strategy. I designed the full product concept, UI flows, and AI logic powering the system.

A client needed a system where her students could book classes, pay online, and manage their schedules — and she needed to run the whole business from one place. I built it alone, start to finish. Teachers see their calendar, students pick a class and pay, the studio owner sees everything. Automated reminders, payment tracking, cancellation handling — all working, all live. One developer. One platform. Running in production. Next.js 15 · React 19 · TypeScript · Prisma · Supabase · PostgreSQL

I needed a better way to find and manage freelance clients. Nothing out there fit, so I built my own. It tracks every lead, every proposal, every follow-up. Then I added an AI assistant that searches job boards for me, finds the ones that match what I do, and puts them in my queue. It runs 24/7 and costs nothing. I open it in the morning and the opportunities are already there. Next.js · TypeScript · PostgreSQL · Ollama · Python

I built a tool that reviews an entire software project and finds every bug, security hole, and problem — automatically. On its first run, it found 60+ issues in a live application, including ways an attacker could access other users' data. Then it fixed them, one by one, and verified nothing broke. Think of it as hiring a senior developer to inspect every corner of your code — except it takes minutes, not weeks. Claude Code · Python · Security Automation

A 36-unit apartment building in Buenos Aires needed to stop chasing residents for payments over WhatsApp. I built a system that automatically sends each resident their expenses, what they owe, and when it's due. Clear numbers, on time, no phone calls. The building administrators went from spending hours every month on this to spending zero. Python · Django · Gmail API · PostgreSQL
