Freelancer profile translated to English.

Description

I am Facundo Tenuta, a Full Stack Software Engineer and AI Specialist based in Madrid. I help startups, agencies, and product teams build production-ready web applications, SaaS platforms, and artificial intelligence solutions.

I have over 6 years of experience working with React, Next.js, TypeScript, Node.js, React Native, and Laravel. In recent years, I have specialized in applied AI products: LLM-powered assistants, RAG, semantic search, workflow automation, duplicate detection, intelligent crawlers, and internal team tools.

My differentiator lies in combining technical execution with product thinking: I can participate from problem definition and architecture to development, deployment, and continuous improvement. I work with a focus on performance, maintainability, user experience, security, and scalability.

I have developed products for sectors such as healthcare, legaltech, eCommerce, SaaS, mobility, education, and internal platforms. I also have experience in cloud and infrastructure using GCP, AWS, Docker, Terraform, Vercel, PostgreSQL, Supabase, Redis, BigQuery, and Spanner.

If you need someone who not only implements features but also understands the business, proposes solutions, and delivers robust software, I can help you.
