I take great pleasure in being able to work at home and be near my wife and three children for a large part of the day.

As an independent, freelance contractor I am solely responsible for the full project life-cycle. Over the course of my career, I have become adept with a wide range of skills from application development to graphic design, project management and technical writing.

From chatbots and content generation to backend automation and intelligent workflow tools, I build systems that are not only technically sound but also smart, scalable, and business-ready. In addition to my technical expertise, you will also find me to be well-spoken, energetic, confident, and personable. I have a strong work ethic, a passion for excellence, and the drive to persevere through the toughest challenges. I thrive on knowledge and the creative use of available resources to solve problems.

🏆 Senior Full-Stack AI Developer | React • Next.js • Node • AI | $200K+ Earned · 100% JSS Founders hire me when their MVP needs to ship in weeks - and still hold up past 100K users. I build AI-powered SaaS and mobile apps that real customers pay for. The kind of code your next developer won't have to rewrite. PROBLEMS I SOLVE Most founders come to me with one of these: ❌ No clear technical roadmap — every developer gives a different answer. ❌ An existing product that's slow, breaking, or impossible to maintain. ❌ A codebase from cheap developers — broken architecture, missed deadlines, technical debt blocking every new feature. ❌ Pressure to ship fast — but no trust left after being burned before. Here's why it keeps happening: most freelancers code feature by feature without thinking about what happens at month six. I don't. Every decision I make — stack, architecture, deployment — assumes your product will grow, your team will change, and the next developer will need to read what I wrote. 120+ shipped projects. 20+ countries. Zero rebuilds requested. ──────────────────────────────────────── WHAT YOU GET 🔷 A technical roadmap before a single line of code is written Every custom enterprise system starts with a plan. As a Full Stack Developer React specialist, I map out stack decisions, data models, and integrations first — whether it's a full stack developer React Node API, a full stack developer Supabase React platform, or a full stack developer React Firebase app. Projects without a plan cost 3x more to fix later. 🔷 A production-ready product, not a dressed-up prototype As a Full Stack Developer React Node developer, I build advanced B2B products ready to go live immediately. Rapid delivery without cutting corners — clean code, testing, CI/CD, deployment pipelines — everything needed to stay live under real load. 🔷 Frontend and UI/UX users actually enjoy As a react developer and web developer, I build fast, intuitive interfaces — CRM systems, dashboards, marketplaces with real-time updates, automation platforms, and SaaS products — as a full stack node.js react system where frontend and backend work as one. For API-driven products I work across react nodejs and react redux architectures. 🔷 Backend systems that don't break under pressure Node js with Express, Django and Flask for Python-heavy workloads, Stripe, and cloud infrastructure — built with proper auth, business logic, and integrations. As a python full stack developer I handle data pipelines, automation, and react js applications where performance matters. 🔷 AI features that add real product value As an AI-focused full stack engineer, I build AI-powered, AI-driven, AI-enhanced, and AI-focused features — agentic workflows, AI-assisted and AI-augmented interfaces, multi-agent systems with MCP, chatbot and chat experiences, and LLM integrations via OpenAI or Claude Code. If your SaaS needs to be AI-native, I know how to build that. 🔷 E-Commerce, CMS & broader stacks As a Full Stack Developer React, Shopify specialist, and wordpress developer, I build storefronts and platforms that convert. I've also worked across laravel vue, mern, ruby on rails, react next node supabase react native, and .net full stack developer codebases — adapting to what you have instead of forcing a rewrite. ──────────────────────────────────────── MY APPROACH 1. Discovery first — I act as your architect and partner before writing a single line. 2. Architecture before code — a plan you approve. No black boxes. 3. Rapid, iterative delivery — real progress every week. I'm a fast builder who doesn't cut corners. 4. Honest communication — you hear about problems from me first. 5. Built to hand off — clean, advanced code your team can work with. ──────────────────────────────────────── SDA COMPANY Behind this profile is SDA Company — a focused, senior software development team I founded. We're not hiring — we're selective. Over 5+ years we've helped clients raise funding, hit deadlines and scale to thousands of users. As CEO and lead specialist, I oversee every project directly. You get a founder with skin in the game, backed by a team that executes. ──────────────────────────────────────── 💡 Have a product to build or a platform to fix? Send me a message - no pitch. Just a real conversation. Stack: React / React.js, Next.js, Node.js, Python, Django, .NET, Laravel, Supabase, Firebase, PostgreSQL, MongoDB, Tailwind CSS, WordPress, MERN, GraphQL, Stripe, AWS, Docker,

Most clients reach out to me after struggling with slow .NET development, messy codebases, and APIs that break under scale. That usually happens when projects are built without the right architecture from day one. If you’re looking for a .NET Developer who builds fast, scalable, and production-ready systems, while using modern AI-assisted development to move quicker without sacrificing quality, you are in the right place. With 8+ years of experience as a .NET Full-Stack Developer, I combine deep expertise in C#, .NET Core, ASP.NET Core, ASP.NET MVC, and Web API with AI tools like Cursor, Claude, and GitHub Copilot to deliver high-quality .NET solutions faster than traditional development approaches. WHAT I DO AS A .NET DEVELOPER I specialize in building complete, end-to-end .NET applications — from backend architecture to frontend delivery and cloud deployment. My work includes: • ASP.NET Core API development — REST APIs, scalable Web APIs, and modern backend systems using .NET 6 and .NET 8 • C# backend development — Clean Architecture, CQRS, Domain-Driven Design (DDD), and SOLID principles • Full-stack .NET development — ASP.NET Core backend with React.js or Angular frontend • .NET Microservices architecture — distributed systems using ASP.NET Core, Docker, Kubernetes, and Azure Service Bus • Entity Framework Core — optimized database design with SQL Server, PostgreSQL, and Azure SQL • Third-party API integrations — Stripe, PayPal, Twilio, Plaid, and external services • Background jobs & event-driven systems — queues, schedulers, and scalable processing in .NET AI-ASSISTED .NET DEVELOPMENT I use AI as a real productivity tool — not just a buzzword. With Cursor, Claude, and Copilot integrated into my workflow: • ASP.NET Core APIs are developed faster with less boilerplate • C# code quality improves through AI-assisted reviews • Debugging complex .NET applications becomes quicker and more efficient • More focus goes into architecture, scalability, and system design This means you’re not just hiring one developer — you are getting the output of an optimized, high-efficiency development process. ASP.NET CORE & API DEVELOPMENT ASP.NET Core is at the core of everything I build. Every API I develop is: • Secure — JWT authentication, OAuth2, Azure AD integration • Scalable — built for cloud environments like Azure • Clean — structured using best practices like Clean Architecture • Documented — Swagger/OpenAPI included by default • Tested — unit and integration testing with xUnit / NUnit • Maintainable — versioned and ready for long-term scaling Whether it’s a new API, scaling an existing system, or modernizing legacy .NET applications — I focus on clean, reliable delivery. FULL-STACK .NET DEVELOPMENT I build complete systems where backend and frontend work seamlessly together: • ASP.NET Core + React.js (TypeScript-based modern apps) • ASP.NET Core + Angular (enterprise-grade applications) • Real-time applications using SignalR • Full database integration with SQL Server / PostgreSQL CLOUD & MICROSERVICES (.NET + AZURE) I design and deploy scalable cloud-native applications using Microsoft Azure: • Azure App Services, Azure Functions, Azure SQL • Azure Service Bus for event-driven architecture • Microservices using ASP.NET Core and Docker • Kubernetes (AKS) for container orchestration • CI/CD pipelines using Azure DevOps MY APPROACH Every project follows a structured approach: • Understand business requirements before coding • Design scalable architecture upfront • Use AI-assisted development to speed up delivery • Write clean, testable, production-ready .NET code • Stay available for improvements, scaling, and long-term support KEY PROJECT EXPERIENCE • Built HIPAA-compliant healthcare platform using .NET Core, ASP.NET Core Web API, and React.js, improving performance and data security • Developed microservices-based systems using ASP.NET Core and Azure, improving scalability and system reliability • Integrated third-party APIs (Stripe, PayPal, Twilio, Plaid) using .NET Web API, automating workflows • Migrated legacy applications to modern .NET Core / ASP.NET Core architecture on Azure, reducing infrastructure cost • Built enterprise platforms (CRM, LMS, SaaS, POS) using C#, ASP.NET MVC, .NET Core, and Entity Framework SERVICES I OFFER • ASP.NET Core web application development • .NET Web API & backend development • C# backend system design • Azure cloud architecture & deployment • Microservices development using .NET • Full-stack development (React.js / Angular + .NET) • API integrations & third-party services
