Former engineer at Goldman Sachs, Amazon, and OKX. I spent 10+ years building financial systems, cloud infrastructure, and large-scale backend platforms.
Today I build small, honest software tools for investors and share the process in public.
🔭 Currently building — PutFinder
A rules-based cash-secured-put screening engine. Each day it scans the full option chain across a curated universe of liquid US stocks, ranks CSP setups on a premium-vs-risk basis from documented indicators (IV30, volatility risk premium, Black–Scholes delta, downside buffer, an earnings gate), and stores a timestamped snapshot for forward-testing.
- 🔍 A transparent research screener — not a signals service, and not investment advice
- 📊 Every factor is documented; the score is a descriptive relative ranking, not a return predictor

- 🏗️ Built in public — progress on X: @jeff410101
🛡️ Also building — ThetaShield
A portfolio risk & capital-efficiency monitor for options sellers. Sync or paste your open positions and it surfaces risk states (Healthy → Monitor → Risk Building → Action Required), delta exposure, theta decay, and APY across every connected account.
- 🧭 Descriptive risk monitoring — read-only, not a trading platform or financial advice
- 📐 Every signal is deterministic and documented: how the risk is measured
