Cut+Dry

Year
Built AI agents for the WSO2 Super App and Con App — intelligent automation and assistant features powered by GPT-4o, LangChain, and a Python FastAPI backend with pgvector.
Full-stack mobile app contributions using React Native — new features, AI integrations, frontend & backend improvements.
Converted the WSO2 Con native iOS/Android app into a React micro app — feature development and bug fixes.
Feature development and bug fixes for the WSO2 Con 2025 mobile app.
Added a feature to directly add the WSO2 TOTP secret — streamlined MFA onboarding using Asgardeo Native Authentication.
PR #382: Fixed ID token validation failure for tokens with multiple audiences — changed jose.jwtVerify() audience param from string to array. PR #416: Added granular config options to disable automatic SDK API calls (SCIM2, organizations, branding) for improved performance and developer control.
Introduced Ballerina methods for the WSO2 pgVector connector — extended vector DB capabilities.
Certified across the WSO2 ecosystem — API Manager, Identity Server, Ballerina, Choreo, Asgardeo and more.
Expo
Open Source Contributor
2025 – Present
Open SourceAdded numeric x-axis support to the Expo UI Chart component — enabling time-series and continuous-axis charts. Updated ChartDataPoint in TypeScript to accept string | number, added transformDataPoint() for Swift interop, and extended all chart mark types (bar, area, line, point, rectangle) in SwiftUI to handle both categorical and numeric axes.
Fixed an Android crash when passing CSS-style rgb()/rgba() strings to props decoded as android.graphics.Color — extended ColorTypeConverter in expo-modules-core to parse these formats, and added Robolectric unit tests to lock the behavior including whitespace variants.
Fixed a documentation inconsistency in expo-secure-store — the docs incorrectly stated that data is deleted on app uninstall, but iOS Keychain data persists after uninstallation by Apple's design. Clarified the real behavior to prevent developer confusion around sensitive data persistence.
Fixed missing documentation for expo-file-system's bundleDirectory — the docs mentioned bundled asset access but provided no working examples. Added clear examples for reading bundled resources (e.g. using arrayBuffer()) to resolve real developer confusion.
