About Me

I’m a Senior Full-Stack Engineer with a strong focus on backend architecture and mobile development, specializing in Java, Spring Boot, and iOS (Swift). With over 10 years of industry experience, I’ve built and scaled production-grade applications across web and mobile platforms, designed secure and efficient REST APIs, and led cross-functional teams through every phase of the software development lifecycle. My work blends technical precision with user-focused design to deliver robust solutions that drive business value.

I build modern, responsive, and scalable websites that help businesses establish a strong online presence. From landing pages to complex web applications, I use React, Vue, Ruby on Rails, PHP, and Laravel to deliver secure, fast, and user-friendly solutions tailored to your goals.

I create high-performance mobile applications for iOS and Android using React Native, Flutter, Swift, and Kotlin. Whether you need an MVP or a fully scalable product, I ensure clean code, smooth performance, and seamless integration with your backend and APIs.
