I build scalable applications with **Next.js, React, Python, Node.js, and Claude** from backend APIs and databases to dashboards, AI agents, and automation. Recently, I’ve delivered AI SaaS projects involving **Claude API integrations, RAG, AI agents, structured outputs, React/Next.js applications, backend/frontend integrations, and production AI workflows**. I work with startups, founders, and product teams that need someone who can take real ownership of features end to end not just complete isolated development tasks. ### What I Can Help You Build * Full-Stack SaaS applications and MVPs * Next.js / React / TypeScript applications * Python / FastAPI backend systems * Node.js APIs and backend services * Claude / Anthropic and OpenAI integrations * AI Agents with tools, APIs, and business data * RAG systems and AI knowledge bases * Supabase / PostgreSQL applications * REST API and third-party integrations * n8n automation and AI workflows * Admin dashboards and internal tools * Stripe payments and subscription systems * Authentication and role-based access * Webhooks, background jobs, and scheduled workflows * Production debugging, optimization, and deployment ### Full-Stack Development I’m comfortable working across the complete application stack. On the frontend, I build responsive and scalable applications using **React, Next.js, TypeScript, JavaScript, and Tailwind CSS**. On the backend, I work with **Python, FastAPI, Node.js, Express.js, REST APIs, GraphQL, PostgreSQL, Supabase, MongoDB, MySQL, and Redis**. This means I can take a feature from the initial requirement through backend logic, database design, API integration, frontend implementation, testing, and deployment. ### AI, Claude & Automation I also specialize in adding AI capabilities to real products and business workflows. My experience includes: * Claude / Anthropic API * OpenAI API * AI Agent development * RAG and vector search * Structured outputs * Tool calling * AI chatbots and assistants * API-connected AI workflows * n8n automation * Business process automation I focus on building AI systems that work reliably inside real applications with validation, permissions, logging, error handling, and business logic around the AI layer. ### Core Stack **Frontend:** React, Next.js, TypeScript, JavaScript, Tailwind CSS **Backend:** Python, FastAPI, Node.js, Express.js, REST APIs, GraphQL **AI:** Claude, Anthropic API, OpenAI, AI Agents, RAG, LLM APIs, Structured Outputs, Tool Calling **Database:** PostgreSQL, Supabase, MongoDB, MySQL, Redis **Automation & Integrations:** n8n, Make, Webhooks, Stripe, Third-Party APIs **Cloud & Deployment:** AWS, Vercel, Docker, GitHub Actions, CI/CD If you’re building a **SaaS platform, full-stack web application, AI-powered product, Claude integration, AI agent, RAG system, or automation workflow**, send me a message with what you’re working on.

I build and improve custom .NET web applications, dashboards, internal tools, admin panels, and client portals using ASP.NET Core, Blazor, React, APIs, and clean backend logic. I can join an existing .NET project, understand the current codebase, fix issues, add new features, improve the frontend/backend, and support the product long-term. My clients typically need one of two things: 1. A new web application, dashboard, admin panel, or client portal built from scratch. 2. A reliable developer to take over and evolve an existing system without breaking what's already working. HOW I HELP: ✅ Build custom .NET web applications for business workflows ✅ Develop dashboards, admin panels, internal tools, and client portals ✅ Improve existing ASP.NET Core / Blazor / React applications ✅ Add new features, fix bugs, and support long-term product development ✅ Integrate APIs, databases, authentication, user roles, and third-party tools ✅ Help businesses replace manual processes with clear, stable, scalable web systems PROBLEMS I SOLVE: ⚠️ Outdated or unstable web applications ⚠️ Internal processes still running on spreadsheets or manual work ⚠️ Existing .NET projects that need bug fixes, new features, or ongoing support ⚠️ Dashboards or admin panels that are hard to use or maintain ⚠️ Business tools that don't scale as the company grows ⚠️ No reliable developer who can understand the codebase and support it long-term WHAT MAKES ME DIFFERENT: Most freelance developers can write code. Fewer can be trusted with an existing, live system. I focus on: ✅ Clean, maintainable backend logic — not quick fixes that create bigger problems later ✅ Understanding the full workflow before building a feature ✅ Clear communication throughout the project ✅ Staying engaged after delivery, not disappearing once the invoice is paid WHAT YOU GET: I build and improve custom .NET web applications designed around your business workflow, not just around a list of technologies. That can mean building a new application from scratch, improving an existing ASP.NET Core / Blazor project, creating a dashboard or admin panel, connecting APIs, fixing bugs, adding features, or providing long-term support. 🎁 INCLUDED WITH EVERY PROJECT: ✅ A high-level review of your current workflow or application structure, with suggestions for improving stability, usability, or maintainability ✅ Suggestions on simplifying features before development starts ✅ A clear breakdown of what to build first, if your project has multiple stages GUARANTEE: If the final result doesn't match the agreed brief, scope, and quality standards, I'll revise it within that same scope until it meets the requirements. MY WORKFLOW: Not sure how to describe the technical task yet? I'll help you structure it. Send me your idea, existing app, requirements, user flow, business process, Figma design, bug list, API docs, or current codebase, and I'll help define the right approach. MY PROCESS: 1. Discovery & requirement review 2. Workflow / codebase understanding 3. Technical planning 4. .NET / ASP.NET Core / Blazor / React development 5. API, database & backend logic implementation 6. Testing, bug fixing & improvements 7. Revisions & final delivery Click the message button, send me your idea, existing app, or technical task, and I'll help you define the next step.
