I hold a Master of Science in Computer Science from the Illinois Institute of Technology and a Microsoft Certified Developer credential. Over 12+ years, I've partnered with reputable US-based clients to architect and deliver web and mobile applications, ecommerce platforms, backend systems, and AI-powered solutions that support real business operations across industries — on time, on budget, and built to last. When mid-size and enterprise teams need a senior developer they can trust with complex, high-stakes projects — they hire me. What I do best: - .NET, PHP Python full-stack development — robust, secure, and enterprise-grade - Mobile app development (iOS & Android) from concept to launch - API design, development, and seamless third-party integrations - SQL Server & MySQL — database architecture, optimization, and performance tuning - AI & machine learning integration — intelligent features built into real products - Legacy system modernization, code audits, and architecture consulting - Full product lifecycle ownership: architecture → development → testing → deployment across Windows, Linux, and Mac environments Need more than one developer? I can provide a dedicated team of experienced developers and project managers for end-to-end delivery — giving you agency-level capacity with senior-level oversight, accountability, and a single point of contact you can trust. Who I work with: Mid-size and enterprise teams who need a technically strong, communicative partner — not someone they have to babysit. Whether you're scaling an existing platform, modernizing a legacy system, integrating AI into your product, or building something from the ground up, I bring the experience and leadership to move fast without cutting corners. Why clients keep coming back: I don't just write code — I bring product thinking, technical leadership, and a genuine investment in your business goals. I ask the right questions upfront, communicate proactively, flag risks before they become expensive, and deliver consistently. My clients value long-term partnerships, not one-and-done transactions. Got a project in mind? Send me a message and I'll get back to you within a few hours.

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.
