Building Smart Web Apps and Automating Your Business Growth

Cover image for I developed a large-scale backend

I developed a large-scale backend automation solution for the real estate sector that collects, analyzes, and structures property metrics. The system uses the GPT-4o-mini model to process large volumes of market data by geographic location and autonomously generate executive analytical summaries. Once the AI processes the information, the system compiles the data into high-quality professional PDF documents ready to download. The entire infrastructure was modularized and containerized using Docker (v3.1), ensuring a clean, scalable, cost-efficient, and highly available cloud deployment for production environments.

I designed and implemented the architecture of a business Artificial Intelligence Agent focused on automating support and capturing potential customers (Lead Generation). The core of the system uses OpenAI GPT-4o orchestrated with LangChain to inject custom context and dynamic knowledge bases. The data pipeline processes user interactions in milliseconds, syncs information in real-time with MongoDB databases, and sends qualified leads directly to the company's CRM. The project includes an advanced analytics dashboard that monitors the agent's performance, managing to maintain an optimal average response time of 1.8 seconds and operating 24/7.

Creation and layout of a premium e-commerce platform focused on the retail and fashion sector. The frontend was developed from scratch using Next.js and TypeScript, prioritizing load speed, SEO optimization, and a smooth user experience on both desktop screens and touch mobile environments (100% responsive design). As an added value to boost conversion, I integrated a custom smart chat widget connected to language models (LLMs), which assists shoppers in real time by autonomously resolving questions about sizes, shipping, and product stock directly on the product page.

I developed a comprehensive real-time inventory management system for modern e-commerce stores. The backend is built on a robust architecture using FastAPI and PostgreSQL, ensuring ultra-fast data processing with stable database connections. The admin panel monitors active user sessions, daily sales balances, and automatic syncing of physical/digital stock, reducing discrepancies to zero. Plus, the system features an optimized mobile payment flow, natively integrated with the Stripe Secure Checkout API to maximize sales conversions safely.
