Worked on client-side SDK modules for enterprise-level cloud desktop and RTC-related products. The work covered permission management, audio/video processing, soft encoding/decoding, remote desktop interaction, SDK integration, and production issue handling. Key responsibilities included maintaining and developing SDK modules, supporting client-side integration, improving runtime stability, and collaborating with product, backend, QA, and customer-facing teams to resolve real-world production issues.

Cloud Desktop SDK / RTC Client-side Modules

Worked on a cloud printing solution for remote desktop and cloud desktop scenarios. The project involved client-side print task handling, virtual printing workflow, document conversion, pre-print processing, task forwarding, status feedback, and failure handling. During implementation, the initial Microsoft PDF Printer-based approach had limitations around automation, permissions, and deployment. The solution was later adjusted to use Ghostscript for document normalization and pre-print processing, with parameter tuning around page size, DPI, scaling, margins, fonts, color mode, and output format.

Cloud Printing / Remote Printing Client-side 

A macOS live captioning tool focused on real-time language understanding, caption display, and accessibility-related use cases. I independently handled product design, macOS client development, audio/caption workflow, user interface implementation, release preparation, and product iteration. This project reflects my experience in desktop application development, real-time user-facing tools, macOS engineering, and independent product delivery.

Kyrifix Caption

A cross-platform dictionary and language learning app built for macOS, iOS, and iPadOS. I independently designed, developed, released, and maintained the product, including the Apple platform UI, dictionary data handling, search experience, user interaction flow, App Store release, and ongoing iteration. This project demonstrates my experience in independent product development, Apple platform engineering, UI implementation, data-driven app design, and long-term product maintenance.

Kyrifix Dictionary

An iOS and watchOS app designed for lucid dreaming practice, sleep-related reminders, and personal tracking. I independently designed, developed, released, and maintained the app, including iPhone and Apple Watch integration, reminder workflows, user-facing interaction design, App Store release, and ongoing iteration. This project demonstrates my ability to deliver a complete Apple ecosystem product across iOS and watchOS, from product idea and implementation to release and maintenance.

Lucid Dream Practice — iOS & watchOS App

Designed and maintained a WebRTC-related P2P networking module that was later modularized into a reusable C++ library for RTC and cloud desktop scenarios. The work covered connection establishment, candidate handling, NAT traversal-related logic, network path validation, transport reliability, and client-side integration. Focused on improving module reusability, API boundaries, integration stability, and maintainability across different RTC client applications.
