Sobre mí
I am a full stack developer who helps turn ideas, unfinished prototypes, and existing web projects into functional products. I work with MVP planning, frontend, backend, databases, APIs, testing, and deployment. I use AI tools such as Claude Code and Codex through a structured process, supported by real knowledge of software architecture and code. I can build or fix the technical work directly, or work alongside you through guided implementation so you understand the process and can continue your project with confidence. I communicate in English, Spanish, and French.... Lee más

May 2025 - Present • 1 yr 2 mos

I created and continue to develop Polygrades, a web platform for researching and analyzing opportunities in prediction markets. I have worked on the complete product lifecycle, including product planning, system architecture, user experience, frontend and backend development, authentication, databases, APIs, testing, documentation, and deployment. The platform is built mainly with Next.js, TypeScript, Supabase, PostgreSQL, Vercel, and GitHub. I also use AI coding tools such as Claude Code and Codex as part of a structured development process, while reviewing the architecture, code, data flows, security, and final behavior myself. Building Polygrades has given me practical experience turning a complex idea into a functional product, solving real technical problems, improving existing systems, and taking features from planning to production.
