I build production-ready apps and websites across iOS, Flutter, and the web — backed by an engineering background that goes from Apple's Human Interface Guidelines down to real-time backend integrations like Dio, Supabase, Firebase and WebSockets.
My foundation comes from Apple's Developer Academy, where I trained under Apple's Challenge-Based Learning methodology — less about following tutorials, more about shipping high-performance, real-world solutions end to end. From there, I went on to work professionally as a Flutter developer on a live enterprise app, and to build web products with React and Next.js.
Featured Projects 🚀
1. Nova (Flutter — Android & iOS)
Contributed to Nova, a production enterprise app used daily by frontline workers at Paragon. Delivered features across five modules, including an achievement system revamp, profile refactor, pagination/lazy loading, and a networking migration to Dio for better error handling and maintainability.
2. BW Party Games (Web — Next.js & React)
Built a real-time multiplayer party game platform that runs directly in a mobile browser, no app install required. Implemented live voting, encrypted role distribution, and a Spotify-powered buzzer game using Supabase Realtime Channels and GSAP animations.
3. Wara' (iOS)
Built an iOS app using Apple's Vision framework to scan Korean packaged food labels and classify ingredients for Muslim consumers, combining real-time OCR with an offline SwiftData database of 2,000+ ingredients.
4. Vocality (iOS & watchOS)
Developed a speech-clarity training app using on-device speech recognition, LLM-based transcript analysis, and Apple Watch haptics to help users catch filler words and unclear articulation in real time.
5. NetExpl (iOS)
A networking and real-time demo app showcasing WebSockets, Multipeer Connectivity, and live message streaming — built entirely on native frameworks with no third-party networking libraries.
6. Velto (iOS & watchOS)
A beginner-friendly 5K training app using the walk-run method, integrating HealthKit, timers, haptics, and watch-phone communication.
7. Jord (MacOS)
Built a macOS app that helps desk-based freelancers fit exercise into unpredictable schedules. Using idle-detection heuristics, it identifies "pocket time" between tasks — waiting on feedback, revisions, or the next idea — and suggests short bursts of light exercise, backed by gamified progress bars and streaks to keep it consistent.
Specialized Skills 🛠️
- iOS & Apple Ecosystem: Swift, SwiftUI, UIKit, MVVM, Vision (OCR), HealthKit, Core Haptics, WidgetKit
- Flutter & Cross-Platform Mobile: Dart, Flutter, Dio, production app delivery in enterprise environments
- Web Development: React, Next.js, Tailwind CSS, Supabase, real-time WebSocket integrations, GSAP animation
- Product & Design: Figma-based prototyping, Apple HIG-compliant UI, accessibility (VoiceOver, Dynamic Type)
Why Work With Me? ✅
I don't just write code in one language and stop there — I move comfortably between native iOS, Flutter, and modern web stacks, and bring the same standard of polish to all three.
- Cross-Platform Range: Real production experience in native iOS, Flutter, and React/Next.js — not just one platform
- Full-Lifecycle Ownership: Comfortable with scoping, technical documentation, development, iteration, and delivery
- Production Experience: Shipped features into a live enterprise app used by real frontline workers, not just personal projects
- Clear & Transparent Communication: Milestone-based delivery, regular updates, and no surprises
If you're looking for someone who can take ownership of your mobile or web product end-to-end, I'd be happy to discuss your project.
