I design and build iOS apps, and I have shipped one to the App Store on my own.

Luminate is an AI journaling app that turns written entries into prayers. 34 Swift
source files, SwiftUI and SwiftData, built solo with no team and no prior developer
job. I handled the architecture, the AI integration, App Store Connect setup,
TestFlight, subscriptions and the release. You can open it here:

Before I started building I spent four years in B2B sales — solar systems at
Novasource Power, IT infrastructure across the Singapore market, and most recently
$20,000-$30,000 a month in new revenue at a 20%+ close rate. That means I can talk
to clients, work from a spec, and explain technical decisions without hand-holding.

I hold a BS in Mechanical Engineering from De La Salle University.

I work fast with AI tooling and I am looking for part-time or contract work,
around 20 hours a week.

I’m a Senior iOS Developer with 8+ years of professional experience building and maintaining production iOS applications across telecommunications, digital payments, enterprise software, and mobile gaming.

My primary expertise is in Swift, Objective-C, UIKit, and SwiftUI. I have experience working on both modern applications and large legacy codebases, including migrating Objective-C components to Swift and maintaining long-running production applications.

Throughout my career, I’ve worked on customer-facing applications used for account management, billing, payments, usage monitoring, and other critical services. I have also developed iOS games, Apple Watch applications, and widgets.

Beyond development, I have experience with technical design, code reviews, mentoring developers, coordinating tasks, resolving technical blockers, and working directly with Product Managers, Product Owners, UI/UX designers, backend developers, and other stakeholders.

Some of my technical experience includes:
• Swift & Objective-C
• SwiftUI & UIKit
• MVVM, MVC, MVP, VIPER, MVVM-C
• REST APIs, JSON, URLSession
• Realm & Core Data
• Swift Concurrency, async/await, Tasks, Actors & GCD
• Auto Layout, SnapKit & Masonry
• XCTest & Xcode Instruments
• Git, Jenkins, Swift Package Manager & CocoaPods
• Firebase & analytics
• App Store Connect & TestFlight
• In-App Purchases, subscriptions & advertising SDKs

I’m comfortable taking ownership of features from requirements and technical design through implementation, testing, code review, and release. I value clean, maintainable code, clear communication, and delivering work on schedule.

I’m currently looking for remote opportunities where I can contribute as a Senior iOS Developer and work with a strong engineering team on meaningful products.
