User-Focused
I believe great software starts with understanding the people who use it. Every decision I make prioritizes the user experience.

Dardan Demiri
Full-stack engineer building commerce, CMS, booking, payment, and business workflow platforms.
I design and ship production web systems with Next.js, TypeScript, Rails, Sanity, Strapi, PostgreSQL, Redis, Docker, and CI/CD — from client-facing websites to backend workflows, payment integrations, admin tools, and content platforms.

About Me
Get to know the person behind the code
I'm a full-stack engineer with 5+ years designing, building, and scaling customer-facing web applications across e-commerce and ed-tech. I've delivered production systems that reduce costs, automate workflows, and measurably improve performance. From a Shopify to MedusaJS platform migration to a containerized LMS and headless storefronts serving 200+ products.
I combine production engineering with first-hand business operations experience. Co-managing a restaurant has given me real-world insight into customer retention, loyalty incentives, and the operational constraints that software has to actually solve for.
I thrive in Agile product teams, communicate clearly across disciplines, and care about shipping work I'm genuinely proud of. Whether you need a scalable e-commerce platform, an internal tooling system, or a content-driven application, I'd love to help bring your vision to life.
Detail-Oriented
The small things matter. I obsess over pixel-perfect implementations, smooth animations, and polished interactions.
Performance-Driven
Speed is a feature. I build applications that are fast, accessible, and work beautifully on any device.
Clean Code Advocate
I write code that's readable, maintainable, and built to last. Today's shortcuts become tomorrow's headaches.
