Pavlos Tzegiannakis is a solo software engineer based in Greece, currently focused on Android development. Passionate about building tools that prioritize usability, Pavlos is especially interested in improving user experience—often overlooked in favor of flashy design.

His latest side project, "Tracker – Manager for Bluesky", reflects this mission. The app helps Bluesky users manage their social connections more effectively by offering real-time follower and following insights, identifying unfollowers or blockers, and enabling bulk actions. It also tracks posts and likes. Designed to be simple, focused, and efficient, Tracker is available on both Android and iOS.

Pavlos launched the first version just weeks after starting development in December 2024. With no paid ads or influencer backing, the app grew organically through Bluesky posts and word of mouth. It reached 100 users within days and now has over 10,000 downloads and around 4,000 monthly active users.

The app is currently free. Pavlos is exploring non-intrusive monetization, such as optional ads or one-time payments, while keeping core features accessible to everyone. His goal: to support the Bluesky community with a trustworthy, useful tool that evolves with user needs.
