Open source development with love.
I develop Android apps and libraries using the latest SDKs, tools and technologies.
I focus on keeping code clean and minimizing data and battery usage.
I create stunning designs focusing on user experience while following a consistent style
e.g. flat design or Google’s Material design.
Design is art!
I help your startup or company in designing and developing any type of Android app or website.
I write code reviews and analyze app and website designs.
Nothing is impossible!
