Building RIZZK: A Disciplined Approach to Risk Management
Why I built a risk calculator for day traders, the lessons learned from managing 500+ users, and what's next for the platform.
The Problem
Most day traders lose money. Not because they can't read charts or spot patterns, but because they don't manage risk properly.
I saw this firsthand when I started trading in college. Smart people making emotional decisions. Overtrading. Overleveraging. Blowing up accounts.
The tools out there were either:
- Too complex: Enterprise-grade platforms with 100 features traders don't need
- Too simple: Basic calculators that don't account for real trading scenarios
- Too expensive: $50+/month subscriptions for students and beginners
The Solution: RIZZK Calculator
I built RIZZK as a focused, free tool that answers one question:
"How much can I risk on this trade?"
Read the full case study with screenshots and technical details on my RIZZK portfolio page.
Key features:
- Account size and risk percentage inputs
- Position sizing based on stop-loss distance
- Break-even and profit target calculations
- Mobile-first design (traders check on their phones)
- Zero cost, zero friction
What I Learned
1. Distribution > Features
The first version had fancy charts and historical tracking. Usage was low.
I stripped it down to the core calculator and added a one-click share feature. Usage exploded.
Lesson: People don't want more features. They want solutions to their immediate problem.
2. Free ≠ Low Quality
Charging $5/month would've made me $2,500/month (500 users). But it would've kept 90% of users away.
Going free meant:
- More feedback from real users
- Portfolio piece that demonstrates my skills
- Proof of execution for future projects
Lesson: Sometimes the value isn't the revenue—it's the distribution and credibility.
3. Tech Stack Matters (For Learning)
I built RIZZK with:
- Next.js (React framework)
- FastAPI (Python backend)
- Azure (hosting and CI/CD)
This forced me to learn full-stack development, DevOps, and cloud infrastructure—skills I use daily now.
Lesson: Side projects are the best classroom.

What's Next
RIZZK is stable and serving 500+ users. Here's what's coming:
- Multi-asset support (options, futures, crypto)
- Trade journal integration (track actual vs. planned risk)
- Mobile app (PWA first, native later)
But the bigger goal is proving a model:
Build focused, free tools for niche audiences. Own the problem, not the price.
Key Takeaways
- Solve one problem exceptionally well
- Free tools can be high-quality portfolio pieces
- Distribution beats features every time
- Side projects are learning accelerators
