Shopify specialist with years of hands-on development experience across Impulse, Impact, Prestige, Symmetry, Dawn, Horizon, Foodie, and most modern OS 2.0 themes. I build custom Liquid sections, fix the things apps can't, and ship clean, schema-driven code your team can actually edit in the theme editor. What I do: • Custom Liquid sections and blocks (schema-driven, merchant-editable) • Theme customization and front-end development (Liquid, CSS, JavaScript) • App integration and troubleshooting (Klaviyo, Judge.me, Appstle, Printify/Printful, Matrixify, and more) • Page speed and Core Web Vitals optimization • Technical SEO (structured data, canonical fixes, Search Console diagnosis, redirect mapping) • Custom landing pages, product page builds, and mobile-first conversion work AI work: • AI-assisted development workflow — I use Claude Code and similar tooling to ship custom Liquid and JS faster and with tighter code quality than traditional hand-coding alone • AI-powered content and SEO — bulk product descriptions, meta titles/descriptions, alt text, and structured data generated and refined at scale • AI features inside the store — chatbots, smart search, product recommendation widgets, and custom integrations with OpenAI/Anthropic APIs How I work: I'm a solo operator — you talk directly to the person writing the code. I give realistic scope up front, split payment 50/50 (milestone on start, milestone on completion), and I don't overbook, so your project actually gets attention. If you've got a specific section to build, a theme to clean up, a migration to plan, an AI feature to wire in, or a store that just needs someone who knows where the bodies are buried in Liquid — send me the details and I'll tell you straight whether I'm the right fit.

👋 Full Stack Developer (React, Node.js, TypeScript) for SaaS platforms, MVPs, and two-sided marketplaces. Part of a full-cycle delivery team - on Upwork since Sep 2010, 14 years in, 300+ contracts shipped, $700K+ earned, 100% Job Success, Top Rated. You get one developer who owns the whole system, plus an agency bench behind her. 💡 Hiring a full stack developer should not mean hiring a React developer and a Node developer in one body. The value is connection: I design how React, the Node.js backend, the database, and business logic move together from day one, so the front end never guesses what the backend means and the backend never returns data the front end does not use. Across 150+ products, that is what keeps React and Node from drifting apart. 🎯 WHAT YOU GET ➜ One accountable full stack developer who scopes honestly, gives a realistic estimate, and ships production-ready code - not two separate implementations stitched together. ➜ A web developer and backend developer in one: I diagnose and fix root causes (slow Node endpoints, CORS and auth errors, dropped env vars, broken React + Node integration), optimize performance, and deliver seamless integration. ➜ A team behind me. If the project grows past one developer, we scale without handing you off to strangers (19,765 hours of high-quality coding delivered). ➜ SaaS: multi-tenant architecture, billing and subscription logic, admin tools, webhook handling, auth and permissions - built for growth in e-learning, real estate, healthcare, fintech, and mobility. ➜ Marketplaces: Stripe Connect flows, booking and availability logic, operator dashboards, multi-role permissions, and complex search, designed as one workflow (buyer, seller, payments, operations). ➜ Backend developer work: REST API design, Express and NestJS services, PostgreSQL and MongoDB data modeling, Redis, event-driven and serverless functions, AWS and Vercel deploys. ➜ Existing codebases: I audit for stability, performance, and code quality, then make step-by-step improvements - no rebuild unless it is truly necessary. ➜ MVPs: a typical V1 ships in 5-6 weeks. One early build I helped ship went on to raise $3M. ➜ Front end: I turn UX designer handoffs into pixel-accurate, responsive UI - React Query strategy, shared TypeScript types, and state that matches the API. 🤖 I use AI coding tools the right way: faster scaffolding, migration prep, and reviews, while architecture, security, data modeling, and API contracts stay human-judged. As a JavaScript developer and software developer at core, I also take python developer work for backend services or data scripts when a project needs it. 🧩 Stack: React, Node.js (nodejs), TypeScript, Express, NestJS, PostgreSQL, MongoDB, Redis, Stripe, AWS, Vercel, Docker, CI/CD. 📊 14 years on Upwork ▪ 300+ contracts ▪ $700K+ earned ▪ 100% Job Success ▪ Top Rated ▪ 150+ products live ▪ 50+ countries ▪ 5,000+ end users on delivered platforms ▪ one MVP scaled to a $3M raise. Roles I take: full stack developer, full stack web developer, react developer, node developer, nodejs developer, backend developer, javascript developer, web developer, software developer, full stack react node developer. 📩 Need a full stack developer for a SaaS platform, marketplace, custom web app, or MVP -- or a backend developer to fix, optimize, and ship an existing React + Node system? Send a message with what you are building and I will give you a direct, practical view of what is involved, fixed-price or hourly.

I build AI-powered SaaS & mobile apps that help startups launch fast and scale and AI trainer. From MVP to production, I handle everything—so you can focus on growth, users, and revenue. ⸻ 💡 What I Do * AI apps (GPT, Claude, automation workflows) * SaaS & MVP development (startup-focused) * Mobile apps (React Native / Expo) * Full-stack systems (React, Next.js, Node, Laravel) * APIs, payments, real-time features ⸻ ⚡ Proven Work * AI legal marketplace (USA) → smart search across 1.3M+ lawyers * BLE sports app (golf) → real-time device tracking with low latency * Healthcare platform → video consultations (WebRTC) ⸻ 🧠 Tech Stack GPT, Claude, Cursor, Replit React, Next.js, Node.js, Laravel React Native, Expo AWS, Vercel, GCP ⸻ 🎯 Why Clients Hire Me * I think like a founder, not just a developer * I build products that scale, not quick hacks * Clean architecture + fast execution * Clear, direct communication ⸻ 👉 Building something serious? Send an invite.

I build reliable web applications that stay working after they ship. If you need a Full Stack Developer who handles Python, Node.js, React, and complicated API Integrations from day one, I'm here to help. If your current project is stuck because of messy APIs or poor Software Architecture & Design, I step in. My job as a Full Stack Developer is taking an idea and making it a running Web Application. I focus on getting things done efficiently, whether you are building a complicated e-commerce platform or need specialized AI Integration for proprietary data. I work hard to make the entire development cycle clear for everyone involved. A good web developer needs to handle both the frontend experience and the back end logic so that the whole thing runs smoothly in production. If your team is looking for a Full Stack Developer who can deliver quality code using technologies like JavaScript, CSS, and HTML5 right away, we should talk. I am a reliable full stack developer helping clients build better digital tools. Over 12+ years as a web developer, I have been building systems from the ground up. As an experienced Full Stack Developer, my background spans multiple core areas of software development. I work across stacks including Django and Laravel backend logic. For example, I spent over 5 years with Python as a full stack developer, working on 20+ backends that use Django or pure Python for Software Development. When building these services, I bring expertise in API Integration and using technologies like MySQL and Git from day one. My work covers everything from the web design layer to complex backend processes. I am a Full Stack Developer helping clients who need solid React developer work paired with strong Node.js backends. I have experience delivering 40+ client projects for about 10 diverse clients, making me a safe choice as your full stack developer. My skills span the entire scope of Full-Stack Development, supporting both Web Application and pure Web Design needs. I am a highly capable web developer who manages multiple tech stacks effectively. For instance, I have delivered several key features like: • Migrating complex Django monoliths to microservices, improving maintenance for 15+ modules in 5 years with the django developer role. • Building real-time data pipelines using technologies like Celery and RabbitMQ that handled millions of daily events across my 8+ year experience as a full stack developer. • Developing secure RESTful APIs using Node.js/Express and TypeScript for SaaS backends, serving over 30 unique API Integrations to different clients. I work with React developer patterns constantly to make sure the user sees something fast and clean. As a Full Stack Developer, I am comfortable acting as a react developer when needed, supporting the frontend build using modern JavaScript and CSS principles. Another example of my capabilities: - Implementing advanced AI RAG systems, connecting LLM APIs via LangChain for up to 5 distinct knowledge sources, backed by professional backend work from the last 1 year. I am committed to being a top-tier web developer and full stack developer. As a Full Stack Developer, I understand that every detail counts, from the Bootstrap usage on the frontend to the query tuning in MySQL on the backend. A good react developer must know how to write clean HTML5 and effective JavaScript for maximum Web Design impact. Many times, clients wrongly assume they need a simple wordpress developer when what they really need is sophisticated full stack development using React or Angular frameworks. I ensure that no one needs a basic wordpress developer if they are ready for real web applications built with Python/Django or Node.js. The best Full Stack Developer helps you avoid the mistakes of a low-skilled wordpress developer at any cost. I am also skilled in advanced backend logic, acting as a dedicated python developer when the task requires it. I ensure that my work exceeds what a generalist full stack developer might offer by mastering core Software Architecture & Design principles. For example, building complex SQL stored procedures and serverless components using Python Lambda functions over 4 years allowed me to deliver reliable systems for critical financial processes. ❌ I'm not a wordpress developer, please don't invite me to wordpress projects ❌ I'm not a mobile app developer, please don't invite me to mobile app projects I bring 12+ years of overall experience as a full stack developer, building reliable Web Applications using technologies like JavaScript and React. My dedication as a Full Stack Developer means you get a single point of contact that knows how to write good CSS, HTML5, use Django, and manage Node.js environments equally well. I am the web developer who makes it run smoothly in production environment every time. Send me your job details or message me directly about your project.
