Johnson Elangbam
Senior / Staff iOS Engineer
18+ years architecting and leading iOS engineering for enterprise clients — Ford, Avaya, AutoZone, Domino's, and Thomson Reuters. Clean Architecture, team leadership, and CI/CD at scale, with hands-on depth in on-device AI integration.
Engineer who architects and leads production-grade iOS systems at scale.
I architect and lead iOS engineering teams building production-grade systems at enterprise scale — Clean Architecture, MVVM, and modular design across VoIP, automotive, retail, and financial domains. I've raised crash-free sessions from 96% to 99%, cut CI/CD release cycles by 30-70%, and mentored 4-5 engineers at a time while staying hands-on in Swift and SwiftUI.
More recently, I've extended that foundation into on-device and cloud AI integration — building hybrid systems like AIAnalyzer, a Swift static analysis tool with AI-assisted fix suggestions. It's a natural extension of the same architectural thinking, not a separate specialty.

iOS Development & Architecture
Building and refactoring iOS apps with Clean Architecture / MVVM, Swift Concurrency, and modern SwiftUI — real track record of turning unstable codebases into reliable ones (96%→99% crash-free, 40-50% fewer production defects).
CI/CD & Release Automation
Cutting build/release cycles from days to minutes (real track record: 30-70% faster releases), automated testing, GitHub Actions pipelines, Homebrew/App Store release automation.
App Stability Engineering
Swift Concurrency migrations (async/await, Actors), thread-safety fixes, crash diagnosis and resolution at production scale.
On-Device & Cloud AI Integration
Building hybrid AI systems that intelligently choose between local inference (Core ML, MLX, Ollama) and cloud APIs (Gemini) — privacy-conscious, cost-conscious AI features for iOS apps.
VoIP & Real-Time Communication
Enterprise voice/video applications, SIP/PJSIP/WebRTC. Background depth from 18 years in the space — available if it's the right fit.

What I've
been building.
AIAnalyzer
A Swift static analysis CLI distributed via Homebrew. Detects architectural smells — God Objects, Large Classes, MVVM violations — with AI-assisted fix suggestions across Cloud, Local, and Hybrid modes.
- Cloud, Local & Hybrid Modes: Evaluates confidence of on-device Qwen2.5 inference, seamlessly escalating to Gemini Cloud when required.
- Deep Static Analysis: Uses SwiftSyntax AST parsing to detect structural rot rather than simple styling lint issues.
- CI/CD Integrated: Outputs SARIF data for native integration into GitHub Code Scanning.
Smart Attendance
iOS app recognizing faces in real time using Apple Vision and a Core ML FaceNet model. Registers faces on-device with zero cloud dependency.
GitHubSeekAndDestroy
macOS security scanner for Apple Silicon. On-demand scanning covering SHA-256 hashing, code signature validation, persistence scanning, YARA integration, and FSEvents monitoring.
GitHubGenesis
A full-stack, fully local AI system to preserve knowledge, voice, and memory. SwiftUI iOS front end backed by FastAPI + local MLX inference (Qwen2.5-14B) — no cloud dependency, no third party.
Meitei Mayek Transliterator
iOS app for OCR extraction and transliteration of the Meitei Mayek script. Includes a custom glyph recognition pipeline — Apple Vision has no native support for this script.
GitHubBLE Robot Controller
iOS app for controlling a robot over Bluetooth Low Energy, demonstrating hardware/IoT integration alongside mobile AI work.
