About Me

Building software & products

I wrote my first line of code in 2010, in C. Today I work mostly with TypeScript, Next.js, React, TailwindCSS, and shadcn/ui. Currently focused on building micro-SaaS products that solve real problems.

I worked at Google for 4.5 years and left to pursue entrepreneurship. I believe in shipping imperfectly and iterating, thinking architecture before coding, and that developer experience matters for productivity.

Engineering Philosophy
                    
                    Ship imperfectly, iterate based on reality
                  
                    Architecture before implementation
                  
                    Validate demand before building
                  
                    DX matters — choose tools that boost productivity
