I'm a mobile developer based in Pristina, Kosovo, with solid experience building native and cross-platform apps. I work with Android (Kotlin), iOS (Swift), Flutter, and React Native — covering the full spectrum from idea to app store launch.
I have a published app in the educational niche, which gave me hands-on experience with real users, performance optimization, and the full release cycle on both Google Play and the App Store.
My focus is on clean architecture, smooth UX, and code that's built to last. Whether you need a native Android or iOS app, or a cross-platform Flutter solution that saves time and budget without sacrificing quality — I've got you covered.
I'm available full-time and work well with remote teams across European time zones. I communicate clearly, deliver on time, and treat every project as if it were my own.
Let's build something great together.…I'm a mobile developer based in Pristina, Kosovo, with solid experience building native and cross-platform apps. I work with Android (Kotlin), iOS (Swift), Flutter, and React Native — covering the full spectrum from idea to app store launch.

I architect and lead cloud, DevSecOps, and AI-driven transformation initiatives that help organizations modernize complex technology environments and turn them into scalable, secure, and high-performing digital platforms.
With 20+ years of international experience across startups, scale-ups, and large enterprises, I’ve worked at the intersection of architecture, platform engineering, and business execution—bridging strategic goals with hands-on delivery. My work focuses on enabling teams to move faster with better reliability, stronger governance, and measurable outcomes.
I specialize in cloud-native architecture on AWS, microservices ecosystems, CI/CD at scale, infrastructure as code, observability, and resilient platform operations. I also design and implement practical AI workflows that improve engineering productivity, reduce operational overhead, and support better decision-making in real production environments.
Throughout my career, I have helped organizations:
• Modernize legacy systems into modular, maintainable, and scalable architectures
• Increase release velocity through automation, pipeline optimization, and DevSecOps practices
• Improve system resilience and operational visibility with robust observability and proactive monitoring
• Strengthen security posture by integrating controls early in the delivery lifecycle
• Align technology decisions with business priorities, cost efficiency, and long-term platform sustainability
My approach is pragmatic and execution-oriented: understand the real bottlenecks, design for scale and maintainability, and deliver incrementally with clear technical ownership. I value clarity, accountability, and engineering discipline, especially in environments where complexity, speed, and reliability must coexist.
I’m particularly motivated by initiatives involving enterprise platform modernization, cloud transformation, AI-enabled engineering operations, and cross-functional technical leadership. I work effectively with CTOs, Heads of Engineering, Product leaders, and delivery teams to translate complex requirements into operationally sound solutions.
Core areas of expertise include:
