EC Markets

• React Native · Java

  Trading Flows That Behave

  Fixes across the order ticket and positions: a submitting state while orders place, Max sized on the broker's unrounded margin rate, margin positions valued at their closing price, live Net P&L on the close sheet, and Position Closing Only status mirrored to TraderEvolution.

• Java · Novu

  One Messaging Platform

  I wired the Novu workflows for onboarding, funding, payment review, document expiry and CRM email, and gave trade notifications their size, price, direction and P&L. Fixing a workflow ID typo restored order-fill notifications that had been silently dropping.

• AWS · Terraform

  Auth Emails That Reach the Inbox

  Verification, password-reset and 2FA emails were plain text and landing in junk. They now go out on branded templates through a Cognito CustomMessage Lambda, with Cognito's managed login branded too, all defined in Terraform.

  App Tracking and Analytics

  I built most of the app's tracking stack: AppsFlyer, Meta, Firebase Analytics and Crashlytics, Google Ads and Apple Search Ads, behind an App Tracking Transparency prompt and iOS privacy config. On the server, one dispatcher sends conversions to Meta CAPI, AppsFlyer and GA4 with a shared event ID, so each purchase is counted once.

  Security Built Into Account Changes

  Email change follows an OWASP-compliant flow with confirmation on both addresses. A "this wasn't me" link cancels it and raises a CRM case, and a session revocation filter rejects any access token issued before the change.

  Compliance and Stability After Launch

  In-app W-8BEN renewal replaced the email reminder and files the form with WealthKernel. Legal documents and Key Information Documents are ordered and shown per product. After launch I fixed production crashes found in Sentry, from push-token registration to live chat.

The five layers I work across, from first visit to a delivered notification.

• Customers now hear about every fill, deposit and expiring document, on email, push and in-app, instead of some order fills never arriving.
• Sign-in codes and verification emails land in the inbox with EC Markets branding, rather than as plain text in junk.
• Marketing can see which channels bring in funded investors across AppsFlyer, Meta, Google Ads and Apple Search Ads, without double-counted conversions.
• A changed email address can no longer be used to keep a hijacked session alive, and suspicious changes reach the support team as CRM cases.
• The team trusts me with production: I'm the first escalation point for notifications and customer-support tooling.
