Senior Full-Stack Application Developer with 20+ years of experience delivering reliable, scalable, and secure web applications. I specialize in ASP.NET / ASP.NET Core MVC, C#, PHP (Laravel, Magento), and complete end-to-end development. I have designed and developed custom CRM, ERP, and CMS systems, student, payment & VISA management platforms for an international education consultancy in Finland, and casino & gambling portals with complex workflows and high-traffic requirements. My skill set includes SQL Server & MySQL, modern front-end technologies (HTML, CSS, JavaScript, TypeScript), and server administration, allowing me to handle everything from architecture and development to deployment and maintenance. I focus on clean code, performance, security, and long-term maintainability — delivering solutions that align with business goals and scale as your product grows.
