Profile Description

Frontend-focused Full Stack Developer with 5+ years of experience building production web applications, from responsive e-commerce and business websites to full-stack platforms with blockchain integrations. Core stack: React, Next.js, TypeScript, Node.js, PostgreSQL, and Redis. I've delivered real estate and healthcare platforms focused on clean UI/UX and conversion, freelance e-commerce builds for Upwork and Fiverr clients (helping some increase user engagement by up to 80%), and several production blockchain applications including ENS marketplaces and decentralized identity systems, working with Ethereum, ethers.js, viem, and smart contracts.

I'm an AI-native developer — I use tools like Claude Code, Cursor, and Replit AI daily to build and ship faster without sacrificing code quality, which means faster turnaround on your project without compromising on craftsmanship.

I've worked remotely with international clients and teams (US, Australia) and I'm comfortable owning a project end-to-end, from requirements through deployment, or slotting into an existing team. Reliable communicator, detail-oriented, and always upfront about scope and timelines.

Open to: frontend/React development, full-stack projects, Web3/blockchain work, and general web development.

Top Skills

Web Programming » Javascript » React JS

Experience: 2 - 5 years

I've been building with React for 5+ years, it's my main tool for building the front end of any web app or website. What I've built with it: A real estate website with property listings, built to work well on both desktop and mobile. A healthcare/nursing platform with multiple sections, forms, and a backend connection (Firebase) to manage user data. Several e-commerce store frontends for freelance clients product pages, cart flows, responsive layouts. Blockchain-based apps where React handled the interface while connecting to wallets (like MetaMask) and smart contracts in the background. A searchable, filterable directory site where I optimized React so the search stayed fast even with a large list of items. What I'm comfortable doing in React specifically: Building reusable components and structuring a project so it's easy to maintain, not just easy to launch. Connecting the front end to APIs/backends and handling loading, error, and success states properly. Making sites responsive and fast, including fixing performance issues when a page starts feeling slow or laggy. Working with Next.js (built on top of React) for projects that need faster page loads and better SEO.
