Six months ago, I was deep in a job search — sending applications, doing LeetCode, going through interview loops — and during all that downtime, I was also obsessively reading about the stock market.
I'm not a finance bro. I'm a developer. But I got really into trading communities online and noticed something frustrating: every platform for stock market discussion was either too noisy (Twitter/X), too gatekept (paid Discord groups), or dominated by memes with zero substance (Reddit's WSB).
So I did what any developer with too much free time does: I built something.
What I Built
MarketChacha is a Reddit-style community platform built specifically for stock market traders and investors. Think of it as a clean, focused forum where you can:
- Share trade ideas with context and reasoning
- Discuss earnings reports, IPOs, and macro events
- Follow other traders and learn from their analysis
- Post watchlists and get community feedback
The name "MarketChacha" — "Chacha" means uncle in Hindi — is a nod to that wise older relative who always seems to know what's happening in the market.
The Tech Stack
Since this is Dev.to, here's what's under the hood:
- Frontend: Next.js with Tailwind CSS
- Backend: Node.js + Express REST API
- Database: PostgreSQL with Prisma ORM
- Auth: JWT-based with Google OAuth
- Hosting: Deployed on cloud infrastructure for reliability
One of the interesting challenges was building the voting/ranking algorithm for posts. I wanted something that surfaced timely content — a hot earnings post should rank higher today and drop off tomorrow. I ended up adapting a decay-based algorithm similar to what Reddit uses, tuned for financial content cycles.
What I Learned Building This While Job Hunting
1. Side projects are interview gold. Every single interview where I mentioned I was actively building and shipping something resulted in a much better conversation. Interviewers love to see that you don't just code for work — you code because you love it.
2. Community building is harder than the tech. Getting the first 100 users to a new platform is genuinely difficult. I've found that showing up consistently in financial Twitter and forums, adding real value in discussions, and organically mentioning the platform when relevant works better than any paid ad campaign.
3. Constraints force creativity. I had zero budget. Everything — hosting, tooling, infrastructure — had to either be free tier or open source. This actually made the architecture cleaner because I couldn't afford to over-engineer it.
4. Ship early, iterate fast. I launched with a very basic version — just post, comment, and upvote functionality. No fancy features. Real users gave me feedback I never would have thought of on my own.
Current Status
The platform is live and growing. We have traders sharing daily watchlists, discussing options strategies, and breaking down chart patterns. The community is still early but the engagement is genuine — people actually read and respond to each other rather than just broadcasting.

For Fellow Developers: Building in Public While Job Hunting
If you're currently in a job search and feeling stuck, I'd genuinely recommend picking a problem you care about and building something — even if it's small. It keeps your skills sharp, gives you something real to talk about in interviews, and honestly? The process of building for real users teaches you things no tutorial ever will.
The job search eventually worked out. But MarketChacha? That's the project I'm most excited about right now.
Have you built anything on the side during a job search? I'd love to hear about it in the comments.
