About me
I'm a developer who loves building things that actually work well and make a difference for people. Over the years I've worked across web, mobile, and AI projects, picking up tools like React, Node.js, Laravel, Flutter, Vue.js, Django, and Python. I don't use every tool on every project—I just like having options so I can choose what fits best.
My work falls into three areas: web apps, mobile apps, and AI-powered products. I try to think beyond just writing code. How fast a page loads, whether Google can find it, whether it still runs well a year later—those details matter to me.
On the frontend I work with React, Next.js, Nuxt.js, and TailwindCSS. On the backend, I reach for Firebase, MongoDB, or PostgreSQL depending on the project. I bring SEO in early too—page structure, meta tags, speed, and mobile design aren't extras you tack on at the end; they're part of building something that gets found and used.
