Approach
Results-Driven
I've spent the last decade building web applications that actually work. Not just the shiny frontend stuff, but the whole stackโdatabases, APIs, deployment, the works. I focus on writing code that other developers can understand six months later.
I've led teams through technical migrations (jQuery to React, monoliths to microservices) and actually shipped them. I enjoy mentoring junior developers and doing code reviews that help people grow.
My approach is pragmatic: use the right tool for the job, optimize when it matters, and keep things simple when possible. I've dealt with everything from small startup MVPs to systems handling millions of records.
Currently working with React, Vue, Node.js, and various databases. I pick up new technologies quickly and I'm comfortable jumping into unfamiliar codebases.
