Working with Mier is a pleasant experience. Aside from being a good and hardworking front-end developer, he is a good workmate. He is kind, approachable and responsive when needed.

Brian Mendoza
Software Engineer @ Entrego

Mier Gonzales was one of my senior developers during my time at Entrego, and he had a significant impact on my growth as a software engineer. Under his guidance, I learned a great deal about best practices in software development, from writing clean, maintainable code to structuring logical algorithms effectively. He consistently emphasized the importance of thoughtful problem-solving and clear code organization, which helped me improve both my technical skills and my mindset as a developer. Beyond his technical expertise, Mier stood out as one of the most approachable and supportive senior developers I’ve worked with. He was always willing to share knowledge, offer constructive feedback, and provide help whenever I encountered challenges. Working with him was not only educational but also inspiring.

I had the pleasure of working with Mier as a Mid-level Software Engineer specializing in frontend development. During our time together Mier consistently demonstrated good technical skills paired with a God-fearing character and integrity. Mier routinely extended himself to support teammates and help us meet our goals, even in challenging times. His humility, empathy, and steadfast commitment created a positive and productive work environment. I appreciate his contributions and am confident he will be a blessing to any team.

I had the pleasure of working with Mier as a front-end developer on our team. Throughout our time together, he consistently impressed me with his technical expertise—especially in React—and his calm, reliable presence. He’s not only skilled at building clean, efficient interfaces, but he also shows a strong willingness to take on challenges and step up when the team needs him most. I’ve seen him handle pressure with grace, particularly during production rollouts, where he remained responsive and solution-oriented. Mier is also approachable, kind, and always willing to collaborate. Any team would be lucky to have someone like him.

Lead QA Engineer @ Entrego

Working alongside Mier was a positive experience. He's not only a talented front-end developer but also a great collaborator. His clear communication and willingness to address any issues promptly made the QA process much more efficient. I always had confidence in the quality of his work, and he was a reliable partner in delivering successful projects.

Paulo Oding
Paulo Oding
Product Manager @ Air21

Working with Mier on our finance related project was a great experience. We only had a short introduction to a new tool that we've used to build an app but he quickly picked things up and was hands-on right from the start. He was a fast learner who took initiative in understanding the platform and applying it effectively throughout the project. From design to deployment, Mier was deeply involved in building the app with me from handling complex workflows, testing features and making sure everything ran smoothly. He was always ready to collaborate, offer solutions, and help move things forward. Even now, although we’re no longer in the same company, Mier generously shares his expertise whenever I need input on our active projects. That says a lot about his character and his genuine willingness to help.

Whether it’s refining UI details or suggesting smart improvements, his attention to usability and layout across different devices really stands out. His work adds real value to the product, and he’s always a dependable and collaborative presence in the team.
