I’m especially comfortable with systems that need strong backend logic and a modern web interface at the same time. Whether the project is built with .NET, .NET Core, ASP.NET MVC, ASP.NET Core, Python, Python Django, FastAPI, React, or Angular, I aim to keep the code clean, the architecture simple, and the product stable as it grows. I also use Azure for hosting, scaling, and production support when the project needs a reliable cloud setup. Over the years, I’ve helped teams launch MVPs, modernize older systems, connect complex APIs, improve performance, and reduce technical debt. I’ve worked across healthcare, retail, fintech, and internal business tools, often stepping in as the full stack developer, .NET full stack engineer, .NET developer, or Python developer clients need when they want both speed and long-term quality. My goal is always the same: build software that works now and stays manageable later. I also bring hands-on experience with full stack development, .NET full stack systems, .NET Core developer work, ASP.NET Core projects, ASP.NET MVC maintenance, Python Django applications, FastAPI services, and Azure-hosted software that needs to stay fast and reliable. Whether the project needs a full stack developer react setup, a React frontend, an Angular interface, or a backend built by a Python developer or .NET developer, I focus on clean code, API integration, and practical delivery that supports long-term growth. 🚀 Let’s build together If you need a full stack developer, full-stack developer, .NET developer, .NET Core developer, ASP.NET developer, ASP.NET Core developer, Python developer, React developer, Angular developer, or full stack developer react partner for your next application, I can help you build it the right way.

I work as a full-stack developer across both layers so nothing breaks at the integration boundary. Node.js and NestJS backends - REST and GraphQL APIs, authentication, Stripe payments, real-time notifications, and CRUD operations connected to PostgreSQL, MongoDB, Supabase, and Neon. As a full-stack developer, I design frontend and backend together so the architecture is coherent end to end. Next.js full-stack applications - server-side rendering and static generation for products where Google ranking and Core Web Vitals matter as much as the feature set. My preferred full-stack framework for public-facing products where performance and search visibility are critical. TypeScript-first full-stack codebases - strict typing end to end, from React component props through to Node.js API response shapes, with consistent Redux state management. A full-stack developer codebase that stays predictable and maintainable as it grows, not one that becomes hard to touch after six months. AI-augmented full-stack development - Claude Code and Cursor are core to how I work as a full-stack developer. You get professional-grade JavaScript code at near no-code delivery speed, with the clean architecture, test coverage, and TypeScript typing that make the codebase maintainable long-term. Legacy modernization - structured refactors for React codebases that have become hard to extend. Improved TypeScript coverage, component architecture, and performance without rewriting everything from scratch. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Tech Stack as a React developer and full-stack developer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Frontend: React, Next.js, Angular, TypeScript, JavaScript, Tailwind CSS, Material UI, Redux ▸ Backend: Node.js, Express, NestJS, REST APIs, GraphQL, Drizzle ORM ▸ Databases: PostgreSQL, MySQL, MongoDB, Supabase, Neon, Firebase ▸ AI Tools: Claude Code, Cursor, Copilot, custom LLM agents for code generation ▸ Testing and DevOps: Jest, Cypress, Playwright, Docker, CI/CD, Vercel, AWS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ I am a senior React developer and full-stack developer specializing in React, Next.js, Node.js, NestJS, and TypeScript.

I’m a full stack developer, react developer, and web developer helping businesses build, fix, and improve SaaS products, web applications, dashboards, internal tools, and client platforms with react, next.js, node.js, supabase, postgresql, API integration, and AI-powered workflows. As a full stack developer, I work across front end and back end development. As a react developer and next.js developer, I build and improve modern web application interfaces, dashboards, admin panels, and client-facing product flows. As a node.js developer, I work on business logic, API integration, authentication, webhooks, oauth, stripe flows, and product functionality that supports real SaaS and web application use cases. My work often combines react, next.js, node.js, javascript, typescript, supabase, and postgresql inside one product. Clients usually hire me when they need a full stack developer who can do more than isolated tasks. They need a react developer who can work inside a real product, a next.js developer who can improve an existing web application, and a node.js developer who can connect front end and back end logic cleanly. I help build MVPs, improve SaaS products, fix broken web applications, stabilize dashboards, extend internal tools, improve client portals, and support existing codebases that need stronger full stack development. A lot of my work is with react, next.js, and node.js products that already exist but need improvement. That can mean bug fixing, maintenance, stabilization, performance improvement, API integration, dashboard development, admin panel development, auth flow fixes, web application cleanup, SaaS feature delivery, or extending an MVP into a more production-ready SaaS platform. I’m comfortable joining an existing codebase and working as a full stack developer, react developer, next.js developer, or node.js developer depending on what the product needs most. I also work with supabase and postgresql when a SaaS product or web application needs database logic, authentication, real-time functionality, role-based access, or cleaner back end structure. In many projects, react, next.js, node.js, supabase, and postgresql work together as the core stack, and that is a stack I’m comfortable building, fixing, and extending. I regularly work on web application and SaaS development that includes API integration, stripe, oauth, webhooks, dashboards, internal tools, and client-facing product flows. As a react developer, I can help build responsive product UI, dashboard UI, admin interfaces, and front end functionality inside larger web applications. As a next.js developer, I can help with product architecture, page flows, performance, routing, feature delivery, and production-ready SaaS implementation. As a node.js developer, I can help with API integration, back end logic, business workflows, third-party services, and server-side product functionality. As a full stack developer, I can connect all of those layers into one working product. I also work with AI when it supports a real SaaS or web application use case. That includes AI integration with OpenAI or Claude APIs, AI-assisted product features, AI workflows inside dashboards and internal tools, and automation that supports web application, SaaS, or client platform functionality. When useful, I can also support web scraping and automation if it fits the product and strengthens a real business workflow. If you need a full stack developer, react developer, next.js developer, node.js developer, or web developer for a SaaS product, web application, dashboard, internal tool, API integration project, MVP, client portal, supabase app, postgresql-based system, or AI-powered product feature, send me a message and I’ll review your project.
