Engineering Lab · personal R&D

My security gate was green on every pull request. It had never scanned a single line.

I found that by testing my own CI pipeline the way you would test a feature. It surfaced ten defects — four of them checks that were installed, reporting a status, and had never once done their job.

The lab is where I write all of it down: the architecture, every decision and what it cost, and the failures I found in my own work. Below is what lives there.

🏗

iOS Architecture

Modular iOS project generated with XcodeGen — separate framework targets for core logic, UI components, and networking. Clean Architecture throughout.

⚙️

CI/CD Automation

One command deploys to both platforms. PR quality gate, build, tag, publish — fully automated on self-hosted runners with a 3-tier Makefile system.

🛡

Quality Gates

Every PR must earn its merge — security scan, lint, unit tests, coverage threshold, and breaking-change detection run before human review starts.

📦

Shared Logic & SDK Distribution

Kotlin Multiplatform shared business logic layer, published as an XCFramework via SPM for iOS and Maven for Android — versioned and released with one command.
