about
Hi I'm Juanes, a Full Stack Developer based in Colombia 🇨🇴 with 3+ years of experience building web platforms end-to-end. I work mainly in JavaScript/TypeScript ecosystem — React, Next.js, and Vue.js on the Front End; NestJS, Prisma, and PostgreSQL on the Back End. My work spans healthcare, SaaS, ERP, and e-commerce, usually for teams working across multiple countries and time zones.
I'm the Co-Founder and Full Stack Developer at Lulos Impulso Digital, where we build web platforms, applications and drive technical and local SEO for clients like CIT • GastroGest Pro • Tiffany Esthetic Group we've delivered measurable results — including 48,000+ search impressions, 708+ organic clicks, and an average Google Search Console position of 8.2.
At Cloudnonic I helped build a multi-tenant healthcare platform with React, TypeScript, Redux Toolkit, React Query, NestJS and Prisma. At Vrband I built a SaaS analytics platform and an ERP system from scratch. I hold C2 English proficiency and a Full Stack Open certificate from the University of Helsinki.
I'm finishing my degree in Systems Engineering at Universidad del Valle. Outside of code, I'm into cinema especially IMAX and learning Japanese, with the goal of traveling to Japan someday and getting by speaking only Japanese.
