Arslan Mushtaq

Sole architect and founding engineer for 3 React Native applications built from scratch. Owning the full stack from architecture and foundation to CI/CD, release governance, and team delivery.

• Led a distributed Agile team of 7 engineers to architect and ship 3 React Native applications from scratch, ran weekly sprint planning, retrospectives, and cross-functional stakeholder reviews to keep delivery on schedule and product direction aligned with business goals.
• Used GitHub Actions and Fastlane to build zero-touch CI/CD pipelines spanning 4 environments (Dev, QA, Staging, Production), cutting build and publishing times by ~85% (1 hour 40 minutes to 10 min), giving the business faster release cycles and reducing the risk of human error in deployments.
• Engineered a full automated test infrastructure from scratch using Appium, WebDriverIO, and BrowserStack (covering Unit, API, Functional, and E2E layers), eliminating approxiamtely 60% to 75% of manual QA work so the team could ship features confidently without QA becoming the release bottleneck.
• Integrated MixPanel, Customer.io, Intercom, Strapi, and Directus into a unified analytics and CMS stack so the product team could track user behaviour in real time and update in-app content without raising engineering tickets, removing a recurring source of cross-team friction.
• Used bundle payload analysis, memory-efficient React Hooks patterns, and a custom Google Cloud CDN with dynamic image optimisation to measurably reduce app load times, directly improving user retention and engagement metrics for the business.

Sole mobile architect for a greenfield React Native application for a health-tech platform serving 25,000+ active users.

• Was the only mobile engineer responsible for a health-tech app used by over 25,000+ active users, built and maintained the entire React Native codebase independently, making all architecture decisions and owning every release from development through production.
• Used Redux Toolkit, React Hooks, and Context API to build a personalised health questionnaire engine spanning 50+ conditional question branches, so the medical team could deliver uniquely tailored wellness assessments to each user at scale without manual configuration per patient.
• Designed a Server-Driven UI system backed by WordPress CMS so the product and medical teams could update in-app content and assessment flows in real time, eliminating engineering involvement for routine content changes and reducing time-to-update from days to minutes.
• Built an AI-powered health chatbot trained on longevity and wellness data, giving users on-demand access to personalised guidance 24/7, reducing the volume of direct support requests and increasing user engagement with the platform.
• Established automated testing from zero using Jest, React Native Testing Library, and Detox, and optimised the mobile acquisition funnel, contributing to a 12% increase in platform traffic and 8% e-commerce revenue growth.

Deployed to Proximus (Belgium's largest telecom) to engineer and maintain high-scale mobile solutions within a large distributed engineering organisation.

• Built and maintained features for the main mobile app of Belgium's largest telecom provider, supporting millions of active subscribers, and worked as part of a large distributed cross-functional team using full Agile ceremonies.
• Used React Native micro-frontend architecture (Re.pack) with federated modules to build features independently from other squads, so the platform could scale engineering output across multiple teams without cross-team merge conflicts or deployment delays slowing delivery.
• Used Appium and WebDriverIO to grow automated E2E test coverage from 45% to 80%, eliminating an entire class of regression bugs before they could reach the platform's millions of users and reducing the business cost of post-release defect fixes.
• Managed complex asynchronous data flows using Redux Saga and Redux Thunk, and integrated Dynatrace and Instabug for enterprise-grade telemetry, giving the business real-time visibility into app health and crash rates at telecom scale.

Led engineering delivery for high-traffic mobile applications, coordinating across a 12-person cross-functional team.

• Built and shipped features across three production mobile applications as part of a 5-person Agile team. Handled everything from writing code and reviewing PRs to managing pre- and post-release processes across iOS and Android.
• Used React Native, Redux, and Firebase (Authentication, Realtime Database, Cloud Functions) to deliver Atheneum Hub's core features with Unit and Functional Testing in place, producing a stable, well-tested app that the business could release on a predictable schedule.
• Used WebSockets to engineer a real-time multiplayer matchmaking engine for TOTL Football Quiz, enabling live head-to-head gameplay between users. The app was later independently published on both the App Store and Google Play, reaching a live player audience.
• Delivered WorkApp v2.0 enhancements in React Native, improving task management workflows and in-app messaging to increase day-to-day usability for the app's business users across iOS and Android.

Founding mobile engineer, built the company's internal React Native mobile applications from scratch, owning the architecture and full mobile ecosystem.

• Was the first and only mobile engineer at a Canadian startup, built all of the company's internal mobile apps from a blank slate while completing a full-time university degree, working 4 to 6 hours every day to meet both client and academic obligations.
• Used React Native to architect and build inventory and business management applications from zero, establishing the codebase architecture, coding standards, and technical documentation that the entire company relied on for 5 years, long after other engineers joined the team.
• Owned the full iOS and Android product lifecycle independently, from architecture and feature development through testing, release management, and ongoing maintenance, while simultaneously self-financing a university education, demonstrating sustained senior-level output under significant personal pressure.
