What I'm looking for

Busco un equipo donde pueda construir interfaces escalables con Angular/React, microfrontends y componentes reutilizables, integrando CI/CD y herramientas de calidad. Quiero seguir llevando IA al producto (LLM + prompts) para automatizar y mejorar procesos internos.

I'm a fullstack developer with over 3 years of professional experience delivering complete web solutions across the entire stack. My deepest expertise is on the frontend — microfrontend architecture with Native Federation, component libraries (Angular Signals, Tailwind CSS), and performance-focused UI with React and TypeScript. On the backend I've built BFF services with Node.js, TypeORM, and Sequelize, designed API-first architectures with Laravel, and managed cloud infrastructure on AWS (Route 53, CloudWatch) with Terraform.

Beyond the traditional stack, I work with vector databases (pgvector) and have implemented RAG (Retrieval-Augmented Generation) pipelines for AI-powered applications. I automate workflows with n8n and integrate LLM APIs (Claude, GPT, Gemini) into real products. I use Claude Code daily with custom skills and MCPs to accelerate development and eliminate repetitive work.

At Instaleap I've built internal platforms including a schema-driven form engine (Toolbelt), a documentation tool used across multiple continents (LeapDocs), and real-time monitoring tools. I care about clean architecture, engineering best practices, and shipping things that actually last.
