A production running, multi-platform social media application built from the ground up, enabling creators to share rich multimedia content, including streaming audio and video, images, and status updates.

I architected and developed the complete tech stack: a high-performance Rust back end, a modern web dashboard, and native Kotlin Multiplatform mobile applications with shared business logic across Android (Jetpack Compose) and iOS (SwiftUI).

FEATURES
• Rich Content Ecosystem: Direct upload and streaming of audio and video content via Mux, image management with Cloudflare Images, creator profiles, and ephemeral status updates.
• Advanced Search: Full-text search across creators and media using Typesense.
• Scalable Architecture: PostgreSQL database with SeaORM, Firebase auth, and comprehensive GraphQL API.
• Cross-platform Mobile: Native performance on both platforms with shared Kotlin business logic, state management via StateFlow and MVVM, and platform-specific UI frameworks.
• Admin Dashboard: Full content management interface built with Leptos, enabling creators and administrators to manage media, profiles, and analytics.
• Production Infrastructure: Docker containerization, cloud deployment ready with health monitoring.

I led the development of a production-ready, cross-platform application for a large agricultural enterprise, delivering a functional beta across web, Android, and iOS. A custom TypeScript–Firestore integration library with a GraphQL-like schema was built to manage complex data models efficiently. The UI was implemented directly from design wireframes using Flutter, ensuring consistent design across platforms, while executive-focused features were introduced to emphasize usability, performance, and scalability. I also contributed actively to code reviews, quality assurance, and architectural decisions within a fast-moving, mid-sized remote team.

KEY CONTRIBUTIONS
• Developed a custom Firestore interface using TypeScript with schema-driven data modeling.
• Built reusable Flutter components and libraries for long-term scalability.
• Implemented smooth UI animations and transitions for enhanced user experience.
• Translated stakeholder and end-user feedback into shipped features
• Optimized application performance and ensured production-grade code quality and usability under very large data sets.
• Collaborated closely with designers, stakeholders, and engineers in an early-stage environment.

A cross-platform mobile application developed with Flutter and GraphQL. I followed best practices to deliver a production-ready, modular application, including a video player and a background audio player. I also set up the CI/CD for the application.

Developed the back end for a social media platform, using Hasura.io and Firebase. A key feature was real-time chat using WebSocket. I also developed the cross-platform mobile application in Flutter, including all social features, feeds, post sharing, real-time chat, badges, and a rewards system. The cross-platform mobile application is pixel-perfect, responsive, and adaptive.

Developed an Excel-like sheet for managing sports events, using React, and integrated it with the rest of the application. I collaborated with a team to add new features to a production web application, using React and Redux. We used GraphQL and Apollo client in the complex application setup and Docker for the development environment.
