Project History
Portal — MPC Crypto Wallet SDK (Android, Maven Central)
https://www.portalhq.io/I served as the lead Android developer on Portal's MPC crypto-wallet SDK, used by Bitso and other crypto apps serving millions of monthly active users and multi-million-dollar transaction volumes. I unblocked a long-standing release problem by publishing the multi-module Android SDK to Maven Central. Previously, the in-house team couldn't, so clients updated via manual binary handoffs every version; now they consume it through standard Gradle dependencies. Further, I contributed to Portal's React Native SDK and built an Android-SDK-powered Flutter example app so consumer developers could integrate with minimal support.
Yahoo Fantasy Sports — Stability & MVP-to-MVVM Refactor (Android)
https://play.google.com/store/apps/details?id=com.yahoo.mobile.client.android.fantasyfootballAs a senior Android engineer on the Yahoo Fantasy Sports app, I owned stability and architecture across the Daily Fantasy and Core Fantasy modules. Further, I rebuilt critical user-facing screens (contests, lineups) in the Daily Fantasy module. Additionally, I led the MVP-to-MVVM refactor, lifting duplicated business logic into a dedicated domain layer. Moreover, I drove crash and ANR rates down release over release using Sentry, Embrace, and QA-filed Jira signal.
SportFX — AI Sports Biomechanics (Flutter, Android & iOS)
https://play.google.com/store/apps/details?id=ai.sportfx.analysisAs the lead Flutter developer for SportFX, an AI-powered sports-biomechanics app built for Android and iOS, I owned its architecture. Further, I led the architectural foundation, a scalable MVVM structure for maintainable, testable code. Additionally, I designed and enforced a Figma-aligned design system with multi-theme support, keeping UI/UX consistent across the app. Moreover, I mentored 4 junior developers through detailed PR reviews and pair programming.
Unified Remote – 10+ Million Installs · Performance (Android & iOS)
https://play.google.com/store/apps/details?id=com.Relmtech.RemoteTaking over the Android and iOS apps of Unified Remote, a WiFi/Bluetooth universal remote for Windows, Mac, and Linux with 10+ million installs, I was tasked with modernizing and speeding them up.
To achieve this goal, I implemented a solution that resulted in 3 times faster live-image rendering by moving bitmap uploads to the GPU on a background thread. This optimization helped bring frame times and memory under Android Vitals limits. Additionally, I successfully upgraded the aging codebase from min API 9 to 14 in under three months, removing dead and duplicated code along the way.

• Led a squad of 4 within a 30+ developer Mobile org; served as feature owner and GitHub code owner for the Android UI layer.
• Ran PR reviews on a two-week Agile cadence under MVVM and clean-architecture guidelines.

SKEDit Android App
SKEDit is a Java and Kotlin-based scheduling app that lets you schedule WhatsApp messages, schedule SMS, send emails later, schedule posts, and set call reminders.
I took over the SKEDit app with an existing, unstable, and underperforming codebase rapidly. I worked closely with the original developer for a smooth and quick transfer of the domain knowledge. I moved all the duplicated code into relevant repositories to ensure the code is centralized and adheres to the MVP architecture. I also improved the main screen load and rendering time by 4x by separating the unnecessary bundling of five tabs and UI load. I then maintained it by tracking and fixing crashes.

SpaceX Launch Tracker
https://github.com/informramiz/Kotlin-Multiplatform-MobileThis is a cross-platform mobile application written for iOS and Android that displays past and upcoming SpaceX rocket launches, their details, and their success status, such as whether the launch was a success or a failure.
It uses SpaceX REST API to fetch launch information. The data and domain layers are written in Kotlin Multiplatform Mobile (KMM), and the UIs are native, written in Compose and SwiftUI.

MDacne Android App
A Java and Kotlin-based Android app scans and analyzes your facial skin and sends you a personalized acne treatment kit.
I refactored the critical components of the MDacne app to stabilize them in under one week, added social features, such as posting recovery progress to the MDacne community, deleting posts, and analyzing skin differences of side-by-side comparisons.
I wrote the selfie upload and sync feature by working with the back-end developer to prepare the APIs, and added Google Sign In/Up as an alternative onboarding option. I also guided junior developers in writing clean code that follows MVVM.
