A short story
Kevin Julio
Full Stack Developer and frontend specialist.
Education
Systems Engineering at Universidad Simón Bolívar. During my studies I worked on programming fundamentals, data structures, networks, and relational databases. That foundation helps me understand how a complete application fits together, from the interface to persistence and deployment.
Frontend
Frontend is my specialty. I build applications with React, Next.js, and TypeScript, Redux for state management, and REST API integration. I apply Feature-Sliced Design (FSD) to scale by domain. I focus on enterprise platforms, e-commerce, and products with a maintainable frontend architecture.
Full-stack
I also cover the full cycle: REST APIs, business logic, PostgreSQL and MySQL, authentication, roles, and deployment. I work with C# and .NET, Entity Framework Core, Clean Architecture, CQRS, Repository, and Unit of Work. I containerize with Docker and deploy on Linux, Nginx, and AWS EC2 when the product needs it.
Experience
At Silver Holdings S.A.S. I contributed to a financial platform with authentication, digital signature, document management, and REST API integration. I led the frontend of a travel rewards redemption system: I defined the architecture with Feature-Sliced Design and implemented the core features with React, Next.js, TypeScript, and Redux, in an agile team with Backend, UX/UI, QA, and DevOps. I also built Molaryx, a multi-tenant SaaS for clinics; Ferretería Rueda's first Shopify e-commerce store; a headless store with Remix and GraphQL for Verezza; and a full-stack solution with an admin panel, MySQL, and VPS for Chikos Gourmet.
Current focus
I keep deepening frontend and backend architecture. I build interfaces with React and Next.js, design REST APIs, work with relational databases, and ship applications to production with Docker and AWS. Available for remote, hybrid, or on-site roles, and open to relocating to any city in Colombia.
