I am a .NET full stack developer and software architect with 8+ years of experience building scalable web applications using ASP.NET Core, Angular, C#, TypeScript, Microsoft SQL Server, Azure, and modern cloud technologies. Across 35+ projects in defence, renewable energy, fintech, e-commerce, and enterprise SaaS development I have delivered systems that handle real production load, not just demo traffic. What I build as a .NET full stack developer My deepest work is in ASP.NET Core back-end development. I spent years as the lead .NET full stack developer on a platform managing thousands of wind and solar energy installations globally, processing massive volumes of real-time data, building microservices on .NET Core and Azure, and reducing critical downtime incidents by over 40% through improved monitoring and analytics. On another project I built a Loan Origination System in ASP.NET Core that automated the entire loan lifecycle from lead capture to loan issuance, integrating with HubSpot, external CRMs, and RESTful APIs on Microsoft Azure. The client went from manual processing to a fully automated fintech pipeline handling 550+ active applications, cutting processing time by 60%. ASP.NET developer work across enterprise and defence Some of my most complex work as an ASP.NET developer has been in defence and industrial sectors. I modernized a legacy web platform for a company managing 36 high-uptime naval fleet assets, warships that cannot afford downtime. The ASP.NET MVC rebuild reduced manual reporting time by 70% and enabled real-time asset tracking, secure document storage, and streamlined access to sensitive operational data. On another engagement I took over a large workplace management SaaS development project built by a single developer who had left, no documentation, weekly outages, daily hotfixes. I stabilized the ASP.NET Core back-end, eliminated the performance bottlenecks, and reduced unplanned incidents from weekly to zero within two months. ASP.NET Zero and enterprise acceleration ASP.NET Zero is my go-to when enterprise clients need multi-tenancy, role-based permissions, and audit logging without spending the first three sprints on boilerplate. I have used it to accelerate SaaS development on projects in pharma automation, workplace management software, and industrial IoT, cutting initial setup time by 3+ weeks and letting the team focus on actual business logic from day one. On average my clients ship their first production release 30% faster on ASP.NET Zero compared to building from scratch. Full-stack web development across the whole system As a .NET full stack developer I own the entire delivery, ASP.NET Core back-end, Angular or React front-end with clean web design, Microsoft SQL Server and PostgreSQL database design, and Azure infrastructure. I built a Shopify fulfillment tool in ASP.NET Core and React that reduced packing mistakes to zero and cut order processing time by 35%, integrating barcode scanning, inventory management, and connections to 8+ shipping providers. I delivered a fleet management system in .NET Core and Angular handling 1,250+ assets and 845 active rentals simultaneously, with automated reporting that saved operations teams 10+ hours per week. On the front end I work with Angular, React, TypeScript, JavaScript, Next.js, HTML, CSS, Bootstrap, and RESTful API integration, connecting them cleanly to .NET back-ends without creating maintenance nightmares six months later. C# and .NET developer engineering that goes deep Back-end development across 8 years as a .NET developer means I have seen what breaks under real load. I cut a US e-commerce platform's page load time from 8 seconds to 2, directly contributing to a 2x increase in sales. I optimize Microsoft SQL Server and PostgreSQL queries, regularly reducing query execution times by 60-80%, design database schemas that support complex reporting, and build API integration layers connecting .NET systems to CRMs, ERPs, payment gateways, and third-party platforms. I work with Node.js for event-driven services, TypeScript to keep large codebases maintainable, and Python or PHP when projects need scripting layers alongside the core .NET stack. For web development infrastructure I use Microsoft Azure and Amazon Web Services, Docker containers, microservices architecture, and CI/CD pipelines that reduced deployment time by 50% for several enterprise clients. Why clients come back I have worked with clients in Germany, the USA, Australia, the UK, Norway, Denmark, and the Netherlands across renewable energy, defence, fintech, e-commerce, and industrial IoT. What stays the same: I ask the right questions before writing the first line of code, flag problems early, and deliver .NET full stack applications that work in production, not just in development. If you are scaling a SaaS product, modernizing a legacy system, or need a .NET full stack developer your team can build on, let us talk.

I don’t just write code - I build high-performance systems that run themselves. In a market saturated with "95% done but stuck" projects, I provide the senior-level architectural leadership needed to cross the finish line. My experience as a Lead Engineer at Tier-1 tech giants and gaming companies taught me exactly what works in production. Clean architecture ensures your system won't collapse under its own weight. Rock-solid DevOps guarantees flawless deployment. I combine both to turn experimental AI into a reliable, high-performance tool. 𝗧𝗵𝗲 𝗣𝗵𝗶𝗹𝗼𝘀𝗼𝗽𝗵𝘆: 𝗖𝗹𝗮𝘀𝘀𝗶𝗰𝗮𝗹 𝗖𝗼𝗿𝗲. 𝗔𝗜-𝗗𝗿𝗶𝘃𝗲𝗻 𝗩𝗲𝗹𝗼𝗰𝗶𝘁𝘆.
