Web Development

I build fast, modern web applications using cutting-edge technologies — from marketing websites to complex full-stack platforms.

With deep expertise in React, Next.js, and TypeScript, I create solutions that are performant, accessible, and built to scale.

Development Services

End-to-end web development from architecture to deployment.

Marketing Websites

High-performance landing pages and corporate websites built with Next.js, optimized for SEO and conversion.

Full-Stack Applications

Custom web applications with robust backends — authentication, databases, APIs, and real-time features.

Responsive Design

Pixel-perfect implementations that work flawlessly across all devices — mobile, tablet, and desktop.

CMS Integration

Headless CMS setup with Payload, Sanity, or Strapi — giving you full control over content without touching code.

Performance Optimization

Core Web Vitals, image optimization, code splitting, and caching strategies for sub-second load times.

CI/CD & DevOps

Automated deployments, preview environments, monitoring, and infrastructure-as-code on Vercel and AWS.

How I Build

Every project starts with understanding the business problem, not the technology. I choose the right tools for the job.

Modern Stack — I work primarily with Next.js, React, TypeScript, and Tailwind CSS. For backends, I use Node.js with PostgreSQL, Payload CMS, and Vercel for deployment.

Performance by Default — Every site I build targets 90+ Lighthouse scores. I optimize images, minimize JavaScript, implement lazy loading, and use edge caching to deliver fast experiences globally.

Developer Experience Matters — Clean code, type safety, automated testing, and well-documented architectures ensure projects are maintainable long after launch.

Iterative Delivery — I ship early and often. Staged deployments, preview URLs, and continuous integration mean you see progress daily, not monthly.

Technology Stack

Modern, battle-tested technologies chosen for performance and developer experience.

Next.js

React framework — SSR, SSG, App Router, API routes

TypeScript

Type-safe JavaScript for reliable, maintainable code

Tailwind CSS

Utility-first styling for rapid, consistent UI development

PostgreSQL

Relational database for structured data and complex queries

Payload CMS

Headless CMS with full TypeScript support and admin UI

Vercel

Edge deployment, preview URLs, serverless functions

Git & GitHub

Version control, code review, CI/CD workflows

Docker

Containerized development and deployment environments
