Hello! I'm
Jaime Villegas
I merge my engineering background with modern web development to create high-performance digital products. I design and build applications that are not only functional but also logical and maintainable.
About me
My career began in engineering, where I learned the discipline of building things that simply work—robustly and predictably. That analytical foundation is my starting point.
Later, as a developer, I discovered my passion: building things that people love to use. I understood that behind every div there's a person, and that empathy for the end user is as crucial as an efficient algorithm.
This duality is my working method. I combine technical soundness with user-centered design to not only deliver a product that works, but an intuitive and satisfying digital experience.

Portfolio
How engineering and software development come together to create robust solutions.
Software Solutions
This is where ideas become code. I build functional and scalable digital products. In this section, you'll find full-stack web applications built with technologies like React and Tailwind CSS, crafted to be visually appealing while offering robust functionality that solves real-world problems.
Engineering & Hardware Design
The foundation of my logical thinking. Here I showcase my work in mechanical design (CAD), electronics, and automation, where precision is key to solving industrial challenges. This engineering mindset is what I apply today to build robust and well-structured software.
Work Experience
A journey through my most notable professional roles and achievements
Freelance Professional Engineer
As a freelancer, I manage full-cycle projects for international clients, specializing in web development and custom engineering solutions.
- Full-Stack Development: I have built and deployed complete web applications using React, Node.js, and SQL/NoSQL databases, delivering robust and scalable products.
- UI and Component Design: I have created interactive user interfaces and reusable component systems with Tailwind CSS, focusing on usability and user experience.
- Comprehensive Solutions: I have integrated my software and hardware skills for unique projects, including PCB design and CAD simulation.
Frontend Software Engineer
I led the modernization of a legacy software application, transforming it into a scalable, high-performance web solution with React.
- Technical Leadership: I directed the project's frontend architecture, migrating the codebase to a modern component-based system that improved maintainability and development speed.
- Project Management: I translated client requirements into an actionable technical backlog and coordinated the development team, ensuring high-quality deliveries aligned with business goals.
- Impact and Results: The new application offered a significantly smoother and more responsive user experience, establishing a solid technical foundation for implementing future features.
Mechanical CAD Engineer & Project Engineer
I designed custom engineering solutions to optimize industrial processes, working directly with clients from concept to implementation.
- Analysis and Specifications: I analyzed complex client requirements and translated them into detailed technical specifications, a skill I now apply to define the scope of software projects.
- Complex Systems Design: I used CAD tools to model and design mechanical systems (piping, conveyors, etc.), developing a methodical approach to creating logical and efficient systems.
- Foundation for Software: This experience laid the groundwork for my problem-solving and structured thinking abilities, allowing me to build well-designed and robust software.
