Nathan Visser
I’m a Mobile Software Engineer with over 7 years of experience building performant, secure, and user-focused applications across iOS, Android, and cross-platform environments. My professional work spans enterprise-grade solutions primarily using Swift, Kotlin, and C# with a strong focus on clean architecture, MVVM patterns, and agile methodologies. I’ve contributed to high-impact mobile apps in finance, healthcare, and enterprise asset management, delivering features such as biometric authentication, real-time data sync, and virtual care access. I am highly adept at writing maintainable code, optimizing performance, and mentoring junior developers to elevate team output. My goal is to build mobile experiences that not only function flawlessly but also solve real-world problems.
A profound array of experience across languages and frameworks
My vast array of experience in working with different technologies is so expansive that it enables me to not only work with different code bases regardless of platform, but it also allows me to pick up new tech stacks with an expediency that is only enabled by someone with my diversity of experience. Languages that I have studied comprehensively include Swift, Kotlin, Objective-C, Java, C#, C, C++, and Javascript. What you will find after having studied this many languages in depth is that most languages tend to have more in common then they have differences among them. Because of this I am able to pick up new languages with relative ease by simply honing in on what makes them unique as the rest of the language is almost guaranteed to be similar (if not the exact same) as subject matter I have already covered.
Cross-Platform and Native Proficiency
Understanding both native (Swift, Kotlin) and cross-platform (Xamarin, React Native, Flutter) tools allows me to choose the right solution for the product’s needs.
Strong Understanding of UI/UX Principles
I am able to translate design into smooth, intuitive interfaces and I know how to handle gestures, animations, and accessibility.
Performance Optimization Skills
Mobile apps run on resource-constrained devices. I am highly proficient in profiling, debugging, and optimizing performance to provide a smooth user experience.
RESTfull API integration and Backend Communication
Most mobile apps are front ends for cloud-based services. I have expert experience in efficiently and securely integrating with RESTful APIs.
Test-Driven Development and CI/CD Knowledge
I am familiar with automated testing frameworks such as XCTest and JUnit. I am also experienced with continuous deployment pipelines such as Azure DevOps, and GitHub Actions. This allows me to facilitate the delivery of exceedingly reliable, and scalable apps for my clients.
Adaptability and Continuous Learning
Mobile tech evolves rapidly. That’s why I make a point to stay updated on frameworks, OS changes, and best practices — and I am always looking for a better, more effective way to do things. As any innovative software engineer should be.
