"I am pleased to provide this testimonial for Erwin D. Padilla, who completed an internship with Haya Solutions Inc. as a Custom Software Developer Intern.
During his time at Haya Solutions, Erwin contributed to the development and improvement of our company website, hayasolutions.com, using technologies such as Node.js, Next.js, JavaScript, and Builder.io. He supported several important website initiatives and demonstrated strong technical ability, attention to detail, and a positive learning attitude.
Erwin played a key role in developing and improving the Comparison Plans Table Component, including its design and functionality. His work helped create a more flexible, user-friendly component that allows managing rows, columns, and related content through Builder.io’s visual interface.
He also contributed to the Case Study Lead Form and Model, supporting our lead-generation and website data-collection processes. In addition, Erwin worked on mobile optimization tasks, including improving the alignment of the brand slider, pricing component, and mobile menu. These improvements helped enhance the overall user experience for visitors accessing the website from mobile devices.
Beyond feature development, Erwin also assisted in identifying and resolving website bugs, helping ensure a smoother, more reliable browsing experience for our users and customers.
Throughout his internship, Erwin showed a strong willingness to learn, adapt, and take ownership of assigned tasks. He communicated well with the team, accepted feedback professionally, and demonstrated commitment to delivering quality work.
We appreciate Erwin’s contributions to Haya Solutions and are confident that he will continue to grow and succeed in software development and any future professional opportunity he pursues."
