What I'm all about

I'm a dedicated and forward-thinking developer, committed to fully understanding challenges I encounter. I have no problem assuming responsibility for complex tasks, problems, and mentoring people around me.

My interest in technology and software development drives me to seek out new experiences and challenging problems. I enjoy working with experienced peers to help broaden my own knowledge and challenge me to push my skills to the next level.

Open-source Projects

Helping other developers

What I do best

Tech Leadership

I can take a rough idea or vision, and translate that into the technical roadmap it needs in order to be successful. I've helped plan, build tech teams, and led engineers through tough development challenges.


System Architecture

I've designed, developed, and documented the components of many systems for mobile applications, closed and open-source frameworks, and back-end services.


Mobile Development

I've focused my attention on specializing in mobile development while building performant and delightful apps in iOS. Crypto wallets, AR experiments, contact data synchronization, and smart-home integrations are some of the notable experiences I've worked on.


Back-end Development

I've had experience working on back-end systems for collecting and aggregating analytics data, APIs for servicing web and mobile applications, as well as complex multi-container applications.



I am highly proficient in writing Swift code for clients, servers, or the command line. I follow Swift development proposals very closely, and have also helped identify improvements to Swift.


C / C++ / Objective-C

I developed a strong interest in C-family programming languages because they require thorough knowledge of the platform, but reward you with the maximum amount of performance and flexibility.
