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.

I help startups, SaaS companies, and established teams build reliable software that is secure, scalable, and ready for real users. I am a Senior Software Architect and full-stack freelancer with 6+ years of experience delivering API-first platforms, cloud-native applications, AI-enabled products, e-commerce experiences, and high-volume financial systems. My core strength is turning complex requirements into practical architecture and clean, maintainable software—without losing sight of performance, security, delivery speed, or business outcomes. I work across the full product lifecycle: technical discovery, solution architecture, backend and frontend development, database design, AI integration, cloud deployment, testing, optimization, and post-launch support. What I can help you build or improve: • High-performance C# / .NET and ASP.NET Core APIs • SaaS platforms, internal tools, customer portals, and secure dashboards • Microservices, event-driven workflows, REST APIs, GraphQL, and gRPC • AI-powered workflows using Python, LLMs, AI agents, RAG, vector search, and document automation • Cloud infrastructure and delivery pipelines on AWS and Azure • React, Next.js, TypeScript, Vue.js, and modern responsive web applications • PostgreSQL, SQL Server, MySQL, Redis, RabbitMQ, caching, indexing, and query optimization • Authentication and authorization with OAuth2, JWT, RBAC, Auth0, and secure API design • Shopify / headless commerce, Stripe integrations, and third-party API integrations • Docker, Kubernetes, Terraform, GitHub Actions, CI/CD, observability, testing, and release automation I have worked on systems spanning fintech, real estate, enterprise SaaS, Web3, e-commerce, and AI automation. My background includes improving critical API response times by 40%, reducing long-running report execution from 4.2 seconds to 350 ms, modernizing legacy checkout workflows into .NET services that lowered hosting costs by 28%, and launching 20+ custom business and e-commerce websites. My approach is straightforward: 1. Understand the business problem, users, constraints, and success criteria. 2. Recommend a solution that is proportionate to the product stage and budget. 3. Build in clear milestones, with frequent communication and production-quality code. 4. Deliver documentation, clean handoff materials, and a system that your team can maintain. Whether you need a technical partner to architect a new product, an experienced .NET engineer to stabilize or scale an existing platform, or an AI integration specialist to bring practical automation into your workflow, I focus on delivering measurable, dependable results. Primary stack: C#, .NET 8/9, ASP.NET Core, Python, React, Next.js, TypeScript, AWS, Azure, PostgreSQL, SQL Server, Redis, Docker, Kubernetes, Terraform, LangChain, Semantic Kernel, OpenAI-compatible LLM workflows, RAG, Auth0, Stripe, and GitHub Actions. Available for fixed-price projects, long-term development engagements, architecture consultations, performance optimization, and ongoing technical ownership.
