I recently created a small WhatsApp group for competitive programmers who are genuinely committed to improving and are willing to actively participate in discussions.

Preferred Rating

Codeforces (maximum rating): 1400–1800 CodeChef (maximum rating): 1600–1900 LeetCode (contest rating): 1800–2200 If your rating falls within any of these ranges and you're serious about becoming a stronger problem solver, you're welcome to join.

What we'll do Solve problems consistently Upsolve contests together Discuss approaches after attempting problems Learn new algorithms and techniques Keep each other accountable and motivated Important This is not a silent group. The purpose is collaborative learning, so only join if you're willing to interact, discuss solutions, ask questions, and help others. Silent members are not encouraged.

If you have friends in a similar rating range who are looking for serious upsolving partners, feel free to share this with them.

Let's grow together and reach the next rating milestone.

While Codeforces is the perfect training ground for problem solving, building production-ready Android apps brings an entirely different set of daily challenges—like cryptic Gradle sync failures, unexpected runtime crashes, or jagged UI animations.

If you are looking for a focused space to collaborate with other mobile developers, we have started a zero-fluff WhatsApp group dedicated entirely to Android engineering.

What we do in this group:

Solve Blocks Together: Post your stubborn bugs or code exceptions and get a quick second pair of eyes from peer developers.

Support the Community: Help fellow engineers troubleshoot their production, compilation, or layout blockers.

Showcase Design: Share your most impressive UI animations, custom motions, and clean Jetpack Compose transitions.

The community is strictly technical with zero spam or promotional fluff—just real code, real fixes, and better apps.

Whether you are working through complex architecture patterns or just trying to optimize your main thread performance, you are welcome to join us.
