I am a software engineer since 2011 with 7+ years of experience in Android App Development, passionate about building mobile apps.
During my career I worked on large-scale international apps with millions of users.
In my recent projects I took a consulting role to complete challenges like:
- Audit of existing code
- Modernizing the app tech stack
- Tackling quality/stability/performance issues
- Setting up automated build/test/release pipeline
- Coaching junior developers
I was happy to introduce modular application architecture, set up efficient development processes (git flow, code reviews, CI) and advise on new tools to address business needs (A/B testing, analytics, performance monitoring). I also worked on decreasing technical debt and improving the stability and performance of the apps.
I enjoy making Android apps that work like a charm and are loved by users.
