Like a lot of retail traders, I started with spreadsheets.
At first, they felt fine: simple rows, some formulas, a conditional format or two. Then options happened.
Multi-leg trades. Rolling positions. Partial closes. Assignments. My “simple spreadsheet” has transformed into something fragile, slow, and prone to errors.
One broken formula, and my P&L was lying to me.
That frustration motivated me to build Optioneer—not as a startup idea, but as a tool I needed for myself.
This post isn't about a launch. It's what I learned while building a small SaaS as a solo developer. In this field, bad data leads to bad decisions.
