As a freelance software developer, I build modern, scalable and reliable digital products for startups, entrepreneurs and established companies. My work includes web applications, mobile apps, APIs, dashboards, custom software and complex systems that require performance, security and long-term maintainability.

With more than 10 years of experience, I work with technologies such as Laravel, React, Vue, Node.js, Electron, TypeScript and cloud infrastructure. I also develop IoT solutions, hardware-software integrations and real-time data systems for companies that need advanced technical capabilities.

I help clients turn ideas into functional products, improve existing platforms or solve specific technical challenges. Whether you need a complete software platform, a custom backend, internal management tools, an app for your business or technical consulting, I can guide you through the entire process — from architecture to deployment.

If you are looking for a reliable freelance software developer who can design, build and maintain high-quality solutions, let’s work together and bring your project to life.
