Juan G.

I build AI-powered products and take them from idea to scale. I can build your MVP in almost one day! I can prove it. I already did it on other products! I use an extension of AI tools including Claude Code, co-work and design. I've created end-to-end platforms from backend, frontend, mobile, cloud deployments, logo design, app design, social media and terms and conditions using these amazing tools. 🚀Hey! I'm Juan. Product-focused full-stack engineer, 10+ years shipping software that real users depend on. Focused on building and shipping complete products rapidly using AI-augmented development workflows. Experienced in going from idea → design → code → deploy within days using modern tooling and custom integrations. I have a bachelor's degree in Computer Science and over 10 years of experience. These days most of my work is putting LLM features into production, OpenAI and Claude integrations, AI agents, custom MCP servers, on top of Next.js, NestJS and AWS.

I will help and contribute to your project and your needs! 👨‍💻😎 More info about me: I enjoy being challenged and engaging with projects that require me to work outside my comfort and knowledge set, as continuing to learn new languages, technologies and development techniques. In my free time I love doing exercise and reading books. I believe that besides possessing technical knowledge, one must give their best, always be available, proactive, support the team, maintain good discipline and never give up in the face of new challenges. In my case, I fulfill all these aspects.
