I built a site to demystify options pricing for beginners — here's what I learned

Options trading has a massive learning curve, and most educational resources either dumb it down to uselessness or throw you straight into the deep end with the Black-Scholes formula and wish you luck.

I'm a high school sophomore, and after getting interested in finance, I built StrikeLab an interactive options pricing education site that lets you actually play with the variables behind Black-Scholes (strike price, volatility, time to expiry, etc.) and see in real time how the option's value changes.

A few things I ran into building it:

  • Making math intuitive without hiding it is genuinely hard. Most "beginner" explainers avoid the formula entirely, which means users never build real intuition.

  • Volatility is the variable people understand least even people who trade options regularly. Visualizing it helped a lot.

  • The gap between "I understand the concept" and "I can apply this" is where most learners fall off.

Building a Chrome extension to stop me from sending "BAD" prompts to AI

I've been building a Chrome extension to reduce the number of times I have to "fight" with AI before getting the answer I actually wanted.

After discussing with people on PH, my small tool has evolved:

Feature 1: Spots things you may have forgotten to mention: It checks your input while you are typing and catches the blind spots that you possibly need before you hitting "send".

Feature 2: Prompt Organization

Why don’t prediction markets have leverage yet?

We re building SuperPumped a leverage layer for prediction markets.

Prediction markets are growing fast, but traders still have to lock full spot capital because binary outcomes create gap-risk and make traditional liquidations hard.

Our MVP is focused on:

  • Up to 5x leverage

  • Auto-close before resolution

  • Vault-based liquidity

  • Private per-trade execution wallets

  • Backtesting tools for traders

Has replying to other accounts actually grown your audience — or just eaten your time?

There's a piece of growth advice that won't die: "stop posting into the void, go reply to bigger accounts instead." I was skeptical, so I dug into whether the X algorithm actually rewards replies or whether it's just survivorship bias from people who'd have grown anyway.

The short version: there is a real mechanism. Replies aren't dead-end comments a reply on a post with reach can get surfaced to that post's audience and the wider conversation, so you borrow some of the original's distribution. But it's conditional. Low-effort replies ("so true ") go nowhere. The ones that travel add something concrete a counterpoint, a specific example, a number. And the whole thing only compounds if you show up daily, which is where almost everyone falls off.

Responsible Community Research Agents

All my life, I ve been building enterprise software starting companies, scaling products, and successfully exiting ventures.

This is the first time I m building a SaaS product for SMBs, and I quickly realized go-to-market here is completely different from enterprise sales driven by channel partners and RevOps teams.

built an open source SDK for catching AI agent regressions before you ship

been building agents for a while and kept hitting the same problem. fix a failure, change the prompt or model, same failure comes back quietly. nobody catches it until a user does.

built replayd to solve this. captures failed agent runs as regression tests and replays them before you deploy. if the same failure returns after a prompt, model, or tool change, it catches it.

the grading part was the interesting problem. can't use exact output matching because LLMs are non-deterministic. so instead of checking the text, it checks whether the specific failure came back. wrong tool called gets a hard assertion. policy violation gets an LLM judge.

v0.1.2, early but works end to end. zero runtime dependencies in the core.
