Frontend Engineering
Building responsive, accessible and performant user interfaces with React, Next.js, TypeScript and Tailwind CSS. I focus on component architecture, state management and smooth user experiences.

Full-Stack Developer
I build web applications, AI products, scalable APIs and thoughtful digital experiences.
AI Integration
Integrating AI and LLM capabilities into web applications — from intelligent features and automation to AI-powered product flows — without compromising user experience.
Deployment & Cloud
Deploying full-stack applications on Vercel, AWS and modern cloud infrastructure. CI/CD pipelines, performance monitoring and zero-downtime releases are part of how I ship.
UI/UX & Design
Designing interfaces that are both beautiful and usable. I treat design as an engineering discipline — every interaction, animation and visual decision serves the product and the user.
Core Principles
Speed is a feature. I build with Core Web Vitals in mind, ensuring fast and efficient applications.
A great backend deserves a flawless frontend. UI/UX is paramount to everything I build.
In a field that changes daily, adaptability and constant exploration are my strongest skills.
