TradeSage

A trading journal and analytics product with broker imports, plan-gated features, performance analytics and a customizable dashboard, on web and mobile.

Role

Client

The problem

Active traders needed to import trades from their brokers, understand their performance and keep a journal, with free and paid plans and white-label versions for partners.

What I built

  1. 1

    Built the broker CSV import flows with broker detection (Tradovate, Rithmic).

  2. 2

    Implemented plan-based feature gating for free and paid subscriptions.

  3. 3

    Built the analytics charts (profit factor, win rate, net P&L, trade streaks) and the customizable dashboard grid.

  4. 4

    Worked on the journal, white-label announcements, admin statistics, sign-in flows and the React Native app.

Outcomes

  • Second-largest contributor to the codebase by commits
