Senior Full-Stack Software Engineer
I build modern web applications, APIs, and developer tools, with more than a decade of experience working with Angular and full-stack systems.
I started working professionally in software in 2014 and have worked on software across medical, logistics, e-commerce, and other industries. A lot of that work has involved improving older applications, building new features, and making large codebases easier to work with and maintain.
My background covers both frontend and backend development, with Angular, TypeScript, C#, ASP.NET, Node.js, SQL, and Firebase making up much of my day-to-day work. I also work with AI-assisted development, including integrating AI into applications, reviewing generated code, and using agents to automate repetitive development work.
Profile
I care about building software that is clear, maintainable, and dependable, whether I'm working on the interface, the backend, or everything in between.
I'm Cody Tolene, a full-stack software engineer who has spent most of his career building web applications with Angular, TypeScript, C#, ASP.NET, Node.js, and SQL.
I first got into programming in the early 2000s through Flash games, animations, Newgrounds, and whatever else I could figure out how to build. As a teenager, I wanted to understand how websites and games actually worked, so I started learning Flash and ActionScript and kept going from there.
That interest followed me into college, where I moved into C++, C#, JavaScript, HTML, and web development. I built templates and websites, experimented with game development, and learned mostly by making things that interested me.
I still work much the same way today. I like figuring out how things work, solving difficult problems, and building software that people actually enjoy using.
Impact
Update older applications without unnecessarily rebuilding everything.
Build a development process that makes releases boring in a good way.
Create straightforward APIs and services that are easy to understand and maintain.
Create responsive, accessible interfaces that work well without getting in the user's way.
