    Hi everyone, I wanted to share Quantus, a finance learning and practice platform I’m building out of my own frustration with traditional resources. As a dual major in engineering and finance who started my career at a hedge fund, I found it challenging to develop hands-on financial modeling skills using existing tools. Platforms like Coursera, Udemy, Corporate Finance Institute (CFI), and Wall Street Prep (WSP) primarily rely on video-based tutorials. While informative, these formats often lack the dynamic, interactive, and repetitive practice necessary to build real expertise. For example,…

    Quanta▲120

    Hello! I’m an engineer who has spent the majority of my career building financial systems and ledgers in fintech. A theme across those years was how painful traditional accounting software was to use, so I set out to build something better with Quanta. The best way to get started was by building software that would enable the best full-service accounting experience, as well as help business owners understand their business. If you have a software business, I’d love for you to check out our free trial. Any feedback appreciated. Thank you!

    Ray▲293

    I've been using this daily for 4 months and figured others might find it useful. This is my first open source project so would love any feedback. Ray connects to your bank via Plaid, stores everything in an encrypted local SQLite database, and lets you ask questions about your finances in natural language. No cloud, no account, your data is stored on your machine. Before anything reaches the LLM, all PII is stripped — your name, companies, transaction details are redacted and replaced with tokens, then rehydrated locally in the response. The AI never sees who you are.
