About José Carlos

Senior Frontend Engineer | React 18 & Enterprise Architect

Does your product require a complex interface that is scalable, secure, and high-performing?

I am a Systems Engineer and Specialist in Systems Management with over 8 years of experience transforming business requirements into robust frontend architectures. My career has focused on developing enterprise and banking platforms, where precision and stability are critical.

How can I add value to your product team?

High-level React Architecture: I design scalable systems using React 18, TypeScript, and Vite. My focus is on creating maintainable codebases that allow the team to grow frictionlessly.

Performance Optimization: I specialize in reducing load and build times (migrations to Vite with drastic speed improvements) and optimizing renders through lazy loading and code splitting.

Complex Data Management: I am an expert in handling secure data flows, global states with Redux Toolkit, and complex form validation using Zod and React Hook Form.

E2E Testing Culture: I ensure business continuity by implementing automated tests with Cypress to protect critical user flows.

Key Deliverables:

Reusable component systems (MUI, Radix UI, Tailwind).
Audits and refactoring of legacy frontend architectures.
Robust REST API integration with centralized error handling.
My goal is to provide the technical confidence a product team needs to scale with confidence. I work under Scrum methodologies and communicate effectively in Spanish and English.

Experience

  • WEARE DEV S.A.S.
    Senior Frontend Developer
    December 2022 - January 2026 (3 years and 1 month)
    Envigado, AN, Colombia
    I collaborated on a senior frontend team to define and standardize the technology stack (React 18, Vite, Redux Toolkit) and workflows for critical banking applications.

    Architecture and Performance: I designed scalable frontend architectures focused on efficient rendering of large sets of transactional data.

    UI Autonomy: I implemented reusable component systems with Tailwind CSS and Material UI. In the absence of dedicated designers, I managed basic mockups and layouts to ensure functional and consistent interfaces.

    Modernization: I led the migration from Create React App to Vite, drastically reducing build times and improving the developer experience (DX).
