Jaime Simental.

I am currently building my own company, developing SaaS systems and custom websites for private clients. I work on end-to-end solutions, from initial concept to deployment, focusing on creating scalable and maintainable applications that meet specific business needs.

I worked as a Tech Lead for a banking client in the United States, where I was responsible for developing and implementing a comprehensive refactoring plan to address technical debt. I led a team of developers, established coding standards, and architected solutions to improve code quality, maintainability, and system performance. My role involved close collaboration with stakeholders to ensure the refactoring strategy aligned with business objectives while reducing technical debt and improving the overall codebase health.

My responsibilities included making modifications to the nurse recruitment application, helping to implement new features in areas such as chats, notifications, and emails. In some parts of the project, I used .blade files from PHP Laravel to perform server-side rendering logic.

I was responsible for the frontend architecture of several projects, focusing on creating scalable and maintainable codebases. I led the adoption of Next.js and React in some cases, ensuring our development practices aligned with industry standards for performance, accessibility, and SEO. The project was Jhonsson Sciences, a branch of the pharmaceutical company Johnson & Johnson, where I was part of the development of the COVID vaccine presentation site.

I participated in developing an application using the Expo framework, enabling us to compile native applications for iOS, Android, and web from a single React Native codebase. The application included a control panel with graphics and analysis, designed for users managing GPS tracking hardware fleets developed and sold by the company. The GPS modules, created using Particle, were utilized in some robotics trials, including the robot dog 'Spot' from Boston Dynamics, for precise position analysis. I developed the dashboards for these GPS modules, adding detailed insights into the app for the company's fleet management.

I played a fundamental role in developing frontend strategies, establishing standards, and leading refactoring efforts to improve performance. My responsibilities included developing responsive web applications and integrating them with RESTful APIs and backend services. I worked on an ecommerce project and another for a recruitment dashboard, each with their different business logics and complexities.

I worked for the client Boost Mobile, a cellular phone company. My project involved leading the frontend team to refactor the Boost Mobile plan management dashboard. Once completed, support was provided for the same application, focusing on adding new functionalities. Principles such as lazy loading were applied to load components as needed, as well as the use of custom modules to maintain a modular and scalable architecture. Application state management was also implemented using NgRx, optimizing the application's performance.

The client I worked with was Herbalife, where we refactored the ecommerce and adapted it for different countries. Complexity increased when each country had to apply its own rules in the forms, which was a great challenge, but as a team, we successfully developed it.

My first job in the development world. My main function was to convert Photoshop designs to their HTML, CSS, JavaScript, and jQuery versions. I was responsible for implementing templates from scratch until their release to production.
