Create leverage. That is what I do. I build high-performance, secure, reliable software that helps founders and businesses launch and scale with confidence. Since 2010, I have helped founders and established companies turn ambitious ideas, messy workflows, and broken systems into serious software products. Obsession with quality, complete transparency, and no hand-holding - that is how I turn software from a development expense into a business asset. I am an excellent fit if: - You are a founder with a product idea and need more than “someone to code it.” I can help you refine the concept, define the right MVP, validate technical assumptions, choose the right architecture, build the first production-ready version, and support you after launch as the product grows. - You are an established business looking to build a new platform, automate operations, replace spreadsheets, improve workflows, modernize legacy software, scale an existing product, or rescue a bad build. I am especially valuable when the project is too important to gamble on cheap execution, unclear ownership, fragile architecture, or developers who only wait for task lists. I have spent 15+ years building software where failure is expensive, across product types, workflows, and industries including SaaS platforms, AI/RAG systems, internal tools, dashboards, CRM/ERP/POS systems, logistics platforms, marketplaces, real estate software, e-commerce, FinTech, EdTech, HealthTech, data analytics, travel, hospitality, and regulated sports betting The value of that experience is not just knowing different industries. It is knowing the patterns behind them: workflows, permissions, payments, reporting, integrations, data integrity, performance, edge cases, and the business logic that quietly decides whether a product becomes scalable or painful. I personally lead architecture, planning, communication, and delivery. When a project needs more capacity, I bring in my senior team to provide high-level technical ownership and reliable execution. Whether you are a non-technical founder, an operations-heavy business, or a technical team that needs senior delivery support, I will communicate at the right level: clear when needed, technical when useful, and always focused on decisions that move the project forward. I am based in Turkey and regularly work with US, UK, Canadian, European, and Australian clients. I work EST hours with reasonable PST overlap, so communication across time zones is smooth. Don’t settle for mediocre. In a world of ruthless competition, make me your unfair advantage. Send me a message today, and I will map our next steps.

Many companies don't need another developer—they need someone who can understand a complex system, identify technical risks, and build the right solution before writing thousands of lines of code. That's where I help. I'm a Software Architect and Senior .NET Engineer with 20+ years of commercial experience designing, modernizing, and scaling business-critical applications. I specialize in turning complex legacy systems into maintainable, scalable platforms while minimizing business disruption. Over the years, I've worked with startups, SMBs, and enterprise clients, helping them solve technical challenges rather than simply implementing features. What I can help you with ✔ Legacy system modernization ✔ Technical Discovery & Solution Architecture ✔ SaaS platform development ✔ ASP.NET Core / .NET 6-10 ✔ Azure Cloud Architecture ✔ System Design & Technical Leadership ✔ Performance optimization ✔ Multi-tenant applications ✔ REST APIs & Microservices ✔ Database design & optimization (SQL Server) ✔ Identity, Authentication & Authorization ✔ AI integration into existing applications Typical projects • Modernizing large legacy .NET applications • Building new SaaS products from scratch • Designing scalable cloud architectures • Technical due diligence before development starts • Recovering undocumented business logic • Refactoring complex systems • Leading development teams • Solving performance bottlenecks My technology stack • C# • .NET / ASP.NET Core • Azure • SQL Server • Entity Framework Core • Angular • React • Docker • Kubernetes (AKS) • Redis • RabbitMQ • SignalR • OpenIddict • Azure DevOps • GitHub Actions How I work I believe software development starts with understanding the business—not the technology. Before suggesting an implementation, I focus on understanding business goals, existing workflows, technical debt, and future scalability. This approach significantly reduces project risk and helps avoid expensive architectural mistakes. I'm comfortable working as: • Software Architect • Senior Full Stack .NET Developer • Technical Lead • Fractional CTO • Technical Consultant If you're looking for someone who can not only write high-quality code but also help make the right technical decisions, I'd be happy to discuss your project.
