    Frontend Software Engineer Specialist

    Mar. 2026 - Present - Medellín, Colombia

    Develop modern, scalable, and high-performance web interfaces using React and TypeScript for digital solutions in the banking sector.

    I build and maintain frontend modules within a feature-based architecture, facilitating reuse, scalability, and a clear separation of responsibilities.

    I work with independently deployable microfrontends, contributing to a modular architecture that enables faster, more agile, and maintainable deliveries.

    I integrate REST APIs and manage application state with Zustand and TanStack Query, optimizing data synchronization, cache handling, and the overall user experience.

    I refactor components, improve performance, and promote code standards, accessibility, and visual consistency throughout the application.

    I implement unit tests and component tests to strengthen product stability, reduce regressions, and improve deployment quality.

    I collaborate with backend, QA, product, and architecture teams to analyze requirements, define technical solutions, and ensure strong development practices in banking environments.

    Software Engineer

    Jul. 2024 - Dec. 2025 - Medellín, Colombia

    I led the first software project developed in-house for a client, driving the creation of the development area within the company.

    I built accessible and responsive interfaces with React, TypeScript, and Tailwind CSS, integrating REST APIs.

    I applied a feature-oriented architecture; managed global state with Zustand, routing with React Router, and server state synchronization with TanStack Query.

    I implemented interfaces from design specifications, ensuring visual consistency, accessibility, and cross-device/cross-browser compatibility.

    I ensured quality through end-to-end (Playwright) and unit/component (Jest, React Testing Library) tests.

    Professional A (Network Analyst)

    Nov. 2022 - Jul. 2024 - Medellín, Colombia

    I developed internal tools and support features using React and TypeScript to optimize geospatial and telecommunications workflows.

    I provided functional and technical support to the GE Smallworld GIS platform for telecommunications operations, ensuring service continuity and data quality.

    I researched and resolved technical incidents, reducing resolution times and improving system reliability.

About me 👨🏻‍💻

I’ve always been curious about understanding how things work behind a screen. That curiosity led me to software development and, over time, to finding a point I love between logic, product, and creativity.

I’m a Computer Engineer from Medellín 🇨🇴, and I currently work as a Frontend Software Engineer Specialist at Scotiabank, developing digital banking solutions alongside international teams.

I mainly work with React, Next.js, and TypeScript, building modern, accessible, and scalable applications. I’m also interested in understanding the entire system: APIs, backend, architecture, testing, and everything that happens beyond the interface.

I like creating software that not only works, but is also clear, maintainable, and truly useful to the people who use it.

Outside of code, I enjoy chess, Medellín’s rap scene, and continuing to learn about technology, engineering, and everything that combines structure, creativity, and strategy.
