Andriy Z.

I am a Full Stack and Android Developer with more than 6 years of experience building high performance, user focused, and scalable digital products. My expertise spans backend and frontend development, mobile engineering, cloud infrastructure, and product architecture. On the full stack side, I specialize in PHP and Laravel, along with React and Vue for modern frontends. I build robust APIs, modular architectures, clean domain logic, and polished user interfaces that balance performance with usability. I have delivered SaaS platforms, CRM systems, healthcare apps, and real time dashboards used by thousands of users. As an Android developer, I build secure, reliable, and smooth native applications using Kotlin and Java. I focus on clean architecture, offline sync, API integrations, real time updates, and intuitive UI flows that meet Play Store standards. My apps are designed to be maintainable, easily scalable, and optimized across devices. I combine strong engineering skills with product thinking. I work closely with founders, designers, and cross functional teams to plan features, shape architecture, and transform business goals into working software. My mindset is to deliver stable and elegant solutions while moving fast and communicating clearly. I enjoy taking ownership of complex systems, improving code quality, and mentoring teams. I am comfortable leading projects from zero to launch or joining existing systems that need optimization, refactoring, or full modernization. If you are looking for someone who can own the complete development lifecycle across backend, frontend, and Android, I bring experience, leadership, and a deep understanding of how to ship technology that actually works in production.
