This is a submission for the DEV Weekend Challenge: Community
The Problem
It happened again last week.
I was scrolling through Twitter and saw someone post their submission for a hackathon I'd never heard of. Great prizes. Interesting prompt. Deadline: yesterday.
I'm a Senior Software Engineer. I follow hundreds of devs. I'm on Reddit, DEV.to, Discord servers, newsletters. And somehow, I still missed it.
It's not just hackathons either. New frameworks drop and I'm the last to know. A tool that would've saved me 10 hours of work existed for 3 months before I stumbled across it. The dev world moves fast, and keeping up feels like a full-time job on top of an already full-time job.
I don't need more noise. I need a signal.
What I Built: DevPulse 🗞️
DevPulse is a personalized AI briefing tool for developers. You tell it your stack and what you care about — and it surfaces exactly what's relevant to you, right now.
No generic "top 10 tools of the week" listicles. No algorithm trying to sell you ads. Just a clean, focused briefing built around your world as a developer.
What it shows you:
- 🔧 New Tools & Frameworks — relevant to your stack
- 🏆 Active & Upcoming Hackathons — so you never miss one again
- 📦 Notable OSS Releases — the repos worth watching
- 🔥 Community Buzz — what devs are actually talking about
How it works:
- Tell DevPulse your stack (React, Python, Go, AI/ML — whatever you work with)
- Pick your interests (hackathons, OSS, career, new frameworks, etc.)
- Choose your style: Quick Scan or Deep Dive
- Get your briefing — personalized, AI-generated, ready in seconds
Under the hood, it uses Gemini with web search grounding to pull fresh, relevant information — not stale training data.
The Community It's For
This is built for the dev Twitter / online dev community — the people who are constantly building, learning, and shipping. The ones who care about what's next, not just what's now.
Whether you're a solo indie hacker, a team lead at a startup, or someone grinding through hackathons on weekends — DevPulse is for you if you've ever felt like the dev world is moving faster than you can track.
Tech Stack
- Frontend: React + Tailwind (clean, dark, Linear-inspired UI)
- AI: Google Gemini 2.5 Flash with web search grounding
- Rate limiting: API key per user — your key, your quota, your privacy. No black-box backend holding your data.
What I Learned
The hardest part wasn't the code. It was figuring out what not to build.
My first instinct was to build something that aggregated everything — every newsletter, every RSS feed, every subreddit. But that's just recreating the noise problem with extra steps.
The insight that unlocked it: personalization is the feature. A briefing about Rust releases is useless to me if I write Python. Hackathon alerts are noise if I'm not looking to compete. The value isn't in the information — it's in the filtering.
Gemini's ability to reason about relevance and generate structured, scannable output made this possible to build in a weekend.

Drop your stack into DevPulse and let me know what you think in the comments. And if you know of a hackathon I should add to my calendar — hit me up. 😄
Built for the "Build for Your Community" weekend challenge. The community: every developer who's ever felt like the world moved on without them.
