Profile

Experience

1. Flipper Corporation iOS Developer

   2024.06 — present

   Building and running the iOS base app and in-house SDK for Nachocode, a no-code / low-code app builder.

   • The base app for the app-builder service — WebView permission handling, native bridge to our SDK (haptics / in-app messaging / analytics)
   • Custom splash supporting flexible formats (gif · image · mp4) + error popups and localized permission prompts
   • Push data control; build-time -DFlag to compile only the needed features (mirrors Android's Flavor approach)
   • Unified social login (Google · Apple · Facebook · Naver) + QR / barcode scanner & generator
   • Nachocode Developer — the developer companion app for the app-builder service

2. Side projects / refresh side work

   2023.12 — 2024.05

   A short refresh period — and when I started building and running my own side projects in earnest. The groundwork from this time grew into today's jiny.shop.

3. 3i iOS Developer

   2022.08 — 2023.11

   Hardware / 360° camera integration SDKs and a line of production apps. Communicated with in-house devices over CoreBluetooth.

   • Pivo SDK — Bluetooth handshake + remote-controller implementation; split Basic / Pro SDK build targets for B2B sales
   • Pivo Plus — refactored numerous Storyboards to code-based UI; maintained image tracking
   • Pivo Play — full UI overhaul + reworked Alamofire-based server communication
   • Beamo — added InstantUpload for a Samsung C&T contract; implemented Ricoh Theta video comms + 360° photo capture comms

4. Pincrux iOS Developer

   2020.06 — 2022.08

   B2C apps + a B2B offerwall SDK. Worked on both shipped apps and the SDK under one roof.

   • CLUV (discontinued) — social login (Google / Apple), high-volume image compressor, custom FCM push, localization + launch / operations
   • Pay& (discontinued) — UI / server communication implementation
   • Offerwall — B2B project / per-client custom frameworks. Objective-C → Swift migration

5. SCI Information Service Mobile Developer

   2019.04 — 2020.05

   Identity verification / security domain. Worked iOS and Android in parallel, with implementation close to policy.

   • Siren24 — AutoLayout migration, tamper detection / secure keypad / code obfuscation, GCM → FCM maintenance, screen masking in background
   • i-Pin — tamper detection / secure keypad / obfuscation / FIDO adoption
   • iOS SmartView — certificate rotation + enterprise distribution

6. iOS developer study group self-study

   2019.01 — 2019.03

   During a short gap after my first job, I met up with working iOS developers and learned hands-on, project by project. A small learning round bridging two roles.

7. SecureGuard Technology Mobile Developer

   2018.04 — 2018.12

   The starting point of my authentication / security work. At my first job I built a new app on both platforms myself.

   • BOTP — new FIDO + TOTP app built from scratch (iOS · Android)
   • Implemented Python-based server socket communication on both platforms
   • Custom routing that opens a specific screen from a GCM push + launch

Side Projects

The services / apps I run myself live on dedicated pages — each with its architecture, release notes, and what I learned.
