About Me

I'm Leandro Alvarez, a developer specialized in artificial intelligence, automation and scalable digital products. I transform ideas into concrete solutions: from a functional MVP to a complete ecosystem with backend, mobile and automation through n8n or generative AI.

I work with an integral vision: technology at the service of business. I help companies, startups and entrepreneurs reduce time, optimize processes and create experiences that truly impact their users. Every project I develop seeks a balance between performance, design and strategy. I believe in building solutions that generate real impact. I don't just develop software: I create tools that drive projects, empower teams and grow businesses.

💼 My Work

These are some of the projects I'm working on that reflect my approach: combining artificial intelligence, automation and real product development. Each one represents a step in my mission to create solutions that bring tangible value to people and businesses.

🧭 Quirós — Tourist Assistant of Colón

A Telegram chatbot connected to my city, Colón (Entre Ríos), that answers questions about attractions, gastronomy and local events. Developed with n8n, LangChain and an AI agent with RAG connected to a local tourism database. Allows visitors to get real-time updated information through a simple and accessible chat.

🤖 Sentiment API — Opinion Analysis with AI

An API developed with FastAPI and Hugging Face models, capable of analyzing texts and determining if a rating is positive or negative. Integrates a RAG (Retrieval-Augmented Generation) architecture to contextualize responses, enabling more precise and explainable analysis. The project is hosted on Hugging Face Spaces and can be consumed from any external application using Postman or HTTP requests.

💡 Coming soon I'll be adding new projects focused on applied AI, automation and mobile development.

My Tech Stack

I combine traditional development with artificial intelligence tools to build solutions that automate processes, understand context and generate real value for people and businesses.

These are the technologies I use every day to make it possible:

LangChain & LangGraph: I design AI agents and RAG (Retrieval-Augmented Generation) flows with memory, context and custom logic.

FastAPI, Django: I develop lightweight, high-performance APIs that connect AI models, databases and mobile applications.

n8n: I create visual automations and intelligent integrations between systems, without depending on repetitive code.

Hugging Face: I integrate and test open source models for language processing, embeddings and text analysis.

LangSmith: I monitor and optimize conversational agents and AI pipelines in production.

React Native: I develop mobile applications(Android / iOS) connected with intelligent backends.

Kotlin: I create Android mobile experiences with modern architecture and AI-based service integration.

MySQL: I structure and manage the information that feeds models and automations.

Chroma & Embeddings: I build vector databases and semantic search systems for contextual assistants and recommenders.
