I built an AMR (Autonomous Mobile Robot) Fleet Simulator running entirely in the browser using C++ and WebAssembly (No backend server!) Hey everyone! Lately, I’ve been experimenting with bringing low-level systems programming to the web browser. I wanted to see if I could build a high-performance digital twin for Autonomous Mobile Robots (AMRs) without needing any backend server or WebSocket overhead. The result is a browser-based multi-agent fleet simulator. Here is what's happening unde

I will try once again A few weeks ago I posted here asking for feedback on a portfolio analysis tool I was building. The idea is simple: before buying or selling anything, I wanted a way to simulate changes to my portfolio and actually understand the impact instead of relying on gut feeling. So I built S-Markets .

You choose a stock or ETF, time of day, and up to three indicators, and it randomly loads a historical trading session from the past six months. The goal is to practice taking trades as if they were happening live. It includes: Basic and advanced TP/SL management AI trade reviews with a performance score after each

I built an AI-augmented system design practice tool that triggers a live production incident when you submit your design - not just a critique Every system design prep resource I used was static — read a diagram, read the tradeoffs, move to the next one. Nothing ever pushed back on what I actually built. So I built ChaosBench . You design a system on a canvas — drag components, wire them up — and when you submit it, an LLM (Gemini) finds the actual weak point in your specific design and
