React Developer | Full Stack Development | React, Node.js

For over 10 years I have been a reliable full stack developer and React developer partner for SaaS, Healthcare, AI, and IoT companies. My main focus is full stack web development using React, Next.js, and Node.js. 🏆 Expert-Vetted | Top 1% on Upwork | 100% Job Success Score ✅ 10+ Years as a full-stack developer and React developer 🚀 76,800+ hours of full stack React, Next.js, and Node.js development invested across our team Sounds like a fit?

I respond same day. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ As a full stack developer I have contributed to products acquired by tech giants like New Relic, built platforms that integrated with LinkedIn, Twitch, SimilarWeb, Philips, and SAP, worked on cloud infrastructure serving over 150 million monthly users, and helped develop an AI and IVF product that resulted in dozens of successful pregnancies. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗦𝗸𝗶𝗹𝗹𝘀 & 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀 as a full stack developer and React developer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Frontend: React, Next.js, TypeScript, JavaScript, Vue.js, HTML5, CSS3, Tailwind, Bootstrap, Redux, SWR ▸ Backend: Node.js, Nest.js, Express, Koa, WebSockets, Prisma ▸ Databases: PostgreSQL, MongoDB, MySQL, Supabase, Firebase, DynamoDB ▸ Cloud and DevOps: AWS (Lambda, Cognito, Amplify, S3, IoT), CI/CD pipelines, Docker ▸ Mobile: React Native, Flutter ▸ AI Integration: LLM integration, AI-powered SaaS features, data pipeline development ▸ CMS and Web: WordPress, headless CMS, web design, responsive layouts As a full stack developer I handle both the frontend and backend, meaning you get one senior point of contact who understands how every layer of the product connects. Whether you need a React developer for a complex SaaS frontend, a Node.js backend engineer for a scalable API, or a full-stack developer to own the entire build from design handoff to deployment, I take full ownership from the first line of code to production. I also bring team lead and CTO-level experience, including code reviews, CI/CD setup, front end developer reporting, and engineering process design. Smaller teams do bigger things, and I have spent 10+ years proving that well-structured processes and a focused full stack React and Node.js team deliver better outcomes than large fragmented ones. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 I have worked with as a full stack developer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ SaaS and DevOps: scalable full stack React and Node.js platforms for engineering and data teams ▸ Healthcare and BioTech: HIPAA-aware React frontends and full stack Node.js backend systems ▸ AI and ML Products: React interfaces for AI-powered platforms with full stack Node.js and AWS backends ▸ IoT and Infrastructure: Next.js dashboards connected to real-time IoT device data via AWS ▸ EdTech and EduTech: interactive full stack React learning platforms with content management systems ▸ Travel and Legal: full stack React and Node.js product builds across consumer and B2B verticals My full stack developer experience spans these domains because the engineering principles are the same: clean component architecture, reliable Node.js APIs, and a React frontend that feels fast and works correctly on every device. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝗠𝘆 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵 as a full-stack developer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ I have found one consistent truth: well-structured product development processes lead to the best outcomes. I implement SSR and PWA approaches in Next.js where they improve performance, I use TypeScript across React and Node.js for type safety and maintainability, and I deliver regular progress reports so you always know where the build stands. Internal guidelines, structured code reviews, and clear engineering processes mean my team delivers projects with a 90% adherence to initial estimates, which is what long-term clients who have been with us for 1,000+ hours actually care about. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📩 𝗟𝗘𝗧'𝗦 𝗕𝗨𝗜𝗟𝗗 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Check out my past full stack developer projects below, then 𝘀𝗲𝗻𝗱 𝗺𝗲 𝗮 𝗺𝗲𝘀𝘀𝗮𝗴𝗲 and let us build your product together.
