Full Stack Developer | React Node.js Developer | React Native Mobile

Full stack dev, 7+ yrs, allergic to over-engineering :) Property management, logistics with live IoT tracking, marketing platforms, CRM and HR systems, a bit of crypto too. AI is coming for us all, but for now Claude Code just does what I tell it 🤖 Scroll down, the 3D project is already there! Node.js and React is my love but React Native is my passion I'm a senior Full Stack Developer React Node.js with 7+ years building web and mobile apps end to end, from the database up to pixel-perfect interfaces. I live in the JavaScript and TypeScript ecosystem and pair a React and Next.js frontend with a Node.js backend to ship scalable web applications and SaaS platforms. 🏆 7+ years as a Full Stack Developer React Node.js & React Native Mobile Developer 🏆 $100K+ earned on Upwork as Full Stack developer at 100% Job Success Score with Top Rated status 🏆 3,000+ hours as a full stack web developer & React Native mobile developer across 10+ delivered projects 🏆 10+ web app development and mobile app development projects delivered as a Full Stack Developer I'M USUALLY BROUGHT INTO PROJECTS THAT NEED: - a Full Stack Developer who can take a feature from the database all the way to the UI without handing it off - a Backend Developer or Backend Engineer who has kept real production systems running, not just demos - a React Native Mobile Developer to ship a single codebase to both iOS and Android with proper cross-platform mobile app development - a Front End Developer or React developer who gets the React and Next.js UI pixel-perfect - a SaaS Developer who builds for the version you'll have in two years, not just launch day - an MVP developer whose MVPs are made to grow into real SaaS products - a web app developer for web applications where the workflows and business rules are the hard part BACKEND IS WHERE I SPEND MOST OF MY TIME. AS A BACKEND DEVELOPER AND NODE.JS DEVELOPER, THAT MEANS: - designing and shipping backend services in Node.js and TypeScript with Nest.js and Express, the full stack developer react node engine behind most of my progressive web applications - owning data in PostgreSQL end to end, from schema to migrations, plus Redis, MongoDB and DynamoDB where they fit - treating API integration as core work, the kind of api developer territory that covers REST APIs IN A REACT NATIVE MOBILE DEVELOPER ROLE, I CAN TAKE CARE OF: - shipping a single React Native codebase to iOS and Android, real cross-platform mobile app development instead of two separate native teams - setting up React Native with Expo, navigation, push notifications and React Native Firebase for auth, storage and messaging - adding real-time features such as chat and calls with React Native WebRTC, plus offline support and clean mobile app design MY STRONG SKILLS INCLUDE: - Programming Languages: Javascript (ES5+) Typescript C# Solidity - Technologies: Node.js HTML5/CSS3 React React Native Smart Contracts (Ethereum) Ether.js - Frameworks: Express.js Nest.js Next.js Koa.js .NET Core React Native (Expo) - Libraries: Bootstrap Moment.js RxJs Nodemailer Redux Redux-toolkit Axios Sequelize TypeORM Prisma Dapper Entity Framework AutoMapper luxon SocketIO JsonWebToken Storybook - DBMS: MySQL PostgreSQL MongoDB FireBase SQlite3 DynamoDB Redis CosmoDB Neo4j - AI Tools I can use: Cursor GitHub Copilot Codex Claude A note on honesty, because it saves everyone time. I'm not your python developer, php javascript or java backend hire. I won't claim full stack developer php, python full stack developer, ruby on rails, wordpress full stack work as my own.
