Are you looking for a developer who can design your system correctly from day one, avoid costly rewrites, and deliver a production-ready application, not just code that “works”? With 18+ years of professional .NET experience, I help startups, SaaS founders, and enterprises build secure, scalable, high-performance applications using modern Microsoft technologies. I am not just a coder; I am a solution architect who understands business goals, system design, performance, and long-term maintainability. Many clients come to me after struggling with: ✅ Poorly designed architectures ✅ Slow, unresponsive applications ✅ Developers who cannot scale systems ✅ Technical debt blocking growth ✅ APIs that fail under load I solve these problems by building clean, scalable, enterprise-grade systems. 🚀 What I Specialize In ✔ Blazor Application Development -Blazor WebAssembly & Blazor Server -Component-driven architecture -MudBlazor / Bootstrap UI -Real-time dashboards -High-performance rendering -Enterprise admin panels ✔ ASP.NET Core & REST API Architecture -Production-grade REST APIs -Clean Architecture / DDD / CQRS -Microservices & Modular Monolith design -JWT / OAuth / Identity -Payment gateway integrations -Third-party API integrations ✔ Scalable SaaS Platforms (My Strongest Area) If you're building a SaaS product, you want someone who has actually designed them before.

No messy code. 🤝 Who Should Hire Me? You should hire me if: ✅ You want a senior engineer, not a beginner ✅ Your project matters and must be built correctly ✅ You value architecture and scalability ✅ You prefer working with someone proactive If you just want the cheapest developer, I’m probably not the right fit. But if you want high-quality engineering that saves you money long-term, let's talk. 📩 Let’s Build Something Great Send me a message with your project details, I’m happy to provide: ✅ Architecture recommendations ✅ Technology suggestions ✅ Ballpark estimates ✅ Scaling strategies Even before the contract starts.

With more than ten years of experience as a Senior .NET Engineer, I have worked on designing and building strong software solutions for different companies. My main focus is always on building high-quality and reliable systems that can handle heavy workloads and help businesses solve complicated problems. I am committed to using modern software development methods and DevOps practices to make sure every project runs smoothly, is easy to maintain, and truly helps the business. I always try to create software that not only works well today, but can also be improved or changed easily in the future. A key part of my approach is to use Domain-Driven Design, which helps me understand the business and make sure the software matches its needs. I also use Clean Architecture to organize my code so it stays simple, easy to test, and flexible over time. This helps reduce future costs and avoids messy, hard-to-maintain code. I have a full range of technical skills, with a strong focus on the .NET framework, especially C#, ASP.NET Core, and Entity Framework Core. On the user interface side, I have built many web applications using both React and Angular, so I am comfortable working on both the backend and frontend of software projects. My ability to handle all parts of a project means I can lead teams and solve problems at every step of development. I also have hands-on experience deploying cloud-based software using both Azure and AWS. I am skilled at setting up and handling continuous integration and delivery pipelines, mainly with GitHub Actions. Automating the build, test, and deployment process saves a lot of time and helps my team deliver updates faster, more reliably, and with more confidence. Quality is very important to me, and I always make sure that we have strong tests at every level, from small parts of the code to the whole system, so the final product is stable and fast even when many users are online. I have used these skills to make big improvements to large platforms handling millions of transactions, where performance and stability are crucial. In my career, I have worked for clients across different fields, such as financial technology, education, and travel. Some important achievements include designing a portal that serves many clients for the EdTech industry, building advanced API connections for a global travel company, and leading updates for older ERP systems to make them modern and efficient. In every job, I always aim to turn business ideas into technology solutions that support growth and innovation. My technical knowledge is built on a strong foundation in information systems and technology management, with a degree in Management Information Systems. This education helped me understand both how to build good software and how to connect technology plans to business goals. I learned a mix of technical and business skills, including software development, databases, networks, business analysis, and project management. These skills let me build solid products while making sure they solve real business challenges. I am now looking for new opportunities where I can use my skills to build creative and scalable software solutions. I am confident that my strong background, leadership experience, and dedication to excellent quality would make me a good addition to your team.
