6+ years building production web applications | 5,000+ hours of proven client work I’m a full-stack developer specializing in TypeScript, React, Next.js, Node.js, and PostgreSQL, with 6+ years of professional experience building, improving, and maintaining production applications. Over the years, I’ve worked on everything from focused frontend features and bug fixes to complex full-stack applications, refactoring, system design, database work, and long-term product development. One of my longest client engagements lasted several years and included 5,000+ hours of development across multiple systems, databases, technologies, and frameworks. My client described my work as instrumental to delivering their project successfully and specifically highlighted my ability to understand requirements, work independently, and tackle complex full-stack problems.

I care about building software that is reliable, maintainable, and straightforward for the next developer to work with. I'm comfortable entering an unfamiliar codebase, figuring out how the system works, identifying problems, and taking ownership of a task without needing every detail spelled out. I also value clear communication. If requirements are unclear, I'll ask the right questions, identify potential issues early, and help turn an idea into a practical technical solution. Looking for a long-term developer? While I'm happy to help with individual features or fixes, I'm particularly interested in working with companies and teams that need a reliable long-term engineering partner. If you have an existing application that needs improvement, a new product you're building, or a difficult technical problem that needs solving, send me a message and let's discuss it.
