Most often in React/Next.js on the front end with Node or Python on the back, though I've shipped plenty of .NET backends and full ASP.NET Core apps too. 📌 Shopify stores and headless commerce: custom themes, Storefront/Admin API work, headless setups with Hydrogen or Next.js, and third-party app integrations. 📌 AI-powered features: chatbots, document Q&A, internal automation, and custom workflows on top of OpenAI, Claude, and LangChain. I'm comfortable with the messy parts: streaming responses, token costs, function calling, and evals. 📌 Payment systems: Stripe integrations end-to-end, including subscriptions, marketplaces (Connect), webhooks, and fraud handling with Radar. 💎 Tech Stack 💎 Frontend — JavaScript, TypeScript, React, Next.js, SvelteKit, Tailwind CSS, Vue/Nuxt 💎 Backend — Node.js, NestJS, Express, Python with FastAPI, Django, ASP.NET Core, .NET 8, Entity Framework Core, Web API, SignalR, Blazor, Azure Functions 💎 Databases & APIs — PostgreSQL, MongoDB, SQL Server, REST, GraphQL, WebSockets, Socket.IO 💎 Headless CMS & Shopify— Contentful, Strapi, Sanity, Prismic, plus i18n, CDN, and caching setup, Shopify Template, Shopify Store, Shopify Theme, Shopify Architecture 💎 Ecommerce — Shopify Plus, custom themes, Storefront & Admin APIs, Hydrogen, headless Next.js storefronts 💎 AI — OpenAI, Anthropic Claude, LangChain, NLP integrations, AI-assisted dev workflows (Cursor, Copilot) 💎 Payments — Stripe (Payment Intents, Checkout, Customer, Connect, Webhooks, Radar) Cloud & DevOps — AWS, Azure, Vercel, Docker, CI/CD with GitHub Actions 📢 Hi, I'm a senior full stack developer with 8+ years of experience building web apps, ecommerce platforms, and AI-powered tools for startups and established businesses. I work across the entire stack from architecting the backend to shipping polished, fast-loading interfaces, and I've delivered projects ranging from MVPs that needed to ship yesterday to long-running SaaS products scaled to thousands of users. What I care about: clean, performant code that's easy for the next person to pick up. No clever tricks that break in production, no half-finished features, no disappearing mid-project. less
