Overview
Three commercial iOS games live on the App Store, each built using agentic AI engineering practices and monetised via Google AdMob. This is not a hobby portfolio - it is a systematic, deliberate programme of commercial product development that proves a repeatable methodology for taking ideas from concept to revenue-generating App Store products in days rather than months.
Each game deliberately tests a different mobile platform capability. The result is a growing library of reusable components, documented learnings, and production-tested patterns that compound with every release.

What Makes This Commercial
Every game in this portfolio is a monetised product, not a demo or prototype.
Revenue model
Google AdMob integration with rewarded video ads and interstitials. Players choose when to engage with ads - no forced interruptions, no paywalls. The monetisation respects the zen design philosophy across the portfolio while generating real advertising revenue.
Production quality
These are fully featured App Store products with haptic feedback, procedurally generated audio, particle animations, privacy policies, App Tracking Transparency compliance, and multi-device screenshot sets. Each game went through Apple's full review process and meets App Store commercial standards.
Ongoing operation
Live games receive updates, and the portfolio continues to grow. This is an active commercial product line, not a one-off experiment.
Agentic Engineering in Action
The real story here is not the games themselves - it is the engineering methodology behind them. "Vibe coding" gets the headlines, but agentic engineering is the real skill to demonstrate. This portfolio proves a factory model for building commercial software products.
The Methodology
Specs before code
Product specification, design documentation, theming system - all written before touching Xcode. Decomposing the problem into clear, buildable features is where the value lies.
Persistent learnings
Every gotcha is documented. New projects start with accumulated knowledge from previous builds, eliminating repeated mistakes and accelerating delivery.
Reusable components
The AdManager, design system, sound engine, and haptics framework all carry forward from one game to the next. Each release extends a shared component library.
Decomposition over prompting
Problems are broken into features: "design the theming system", then "architect the tile state machine", then "implement the reveal algorithm". This mirrors how enterprise architects decompose complex systems - same discipline, different domain.
Idea to execution speed
Traditional development takes weeks from concept to working prototype. Agentic development takes days from concept to App Store submission.
The Pattern That Scales
Each project builds upon the foundations of the last. The specs get tighter. The components get reused. The learnings accumulate.
This is not "AI writes code for me" - it is a collaboration pattern that scales. The same practices apply whether building a mobile game, a multi-agent data pipeline, or an enterprise architecture deliverable.
The Games
Shade Shift
Pipeline validation: zero to App Store in 3 days
The first game in the series - a deliberate pipeline validation project. The question: how fast can you go from zero to a commercially published App Store product with AI-assisted development? The answer: three days and approximately 950 lines of code.
Shade Shift is a colour perception game where players spot the tile that is a slightly different shade. The grid grows as scores increase and colours become more subtle. No timers, no lives, no stress. The game mechanic was chosen for technical simplicity - grid logic, no physics, no AI, no pathfinding - because the point was proving the end-to-end commercial pipeline, not the game itself.
What it proved
This is a native iOS app with haptic feedback on every tap, procedurally generated sound effects, particle animations, AdMob integration for rewarded video ads, and a published privacy policy. The full commercial pipeline works.
Technical details
MVVM architecture with SwiftUI and @Observable. HSB colour shifting for difficulty progression. Programmatically generated audio. Rewarded video ads via AdMob.
Minesweeper Zen
The satisfaction of Minesweeper without the stress
Classic Minesweeper is a punishment game - one wrong click equals death. Minesweeper Zen flips it: you are discovering treasure. No explosions, no fail state, no anxiety. Same logical deduction, completely different emotional experience.
The design philosophy is ASMR satisfying, not exciting. Soft sounds, gentle haptics, warm colours. The cascade reveal - where tiles dissolve in a ripple pattern like dominoes falling - is the signature moment. Mesmerising, not jarring.
Agentic engineering showcase
This game's writeup explicitly documents the agentic methodology - specs before code, persistent learnings, reusable components, decomposition over prompting. Every puzzle is 100% solvable, validated by a BFS solver before presentation. Daily puzzles are seeded by date so all players get the same board.
Technical highlights
BFS solver validates 100% solvability. Cascade animation with wave-based timing at 0.05s stagger between tiles. Procedural marimba/xylophone tones generated programmatically. Rewarded ads for hints, interstitials after 5 levels.
Signal Zen
A zen memory game where sound IS the puzzle
The most technically ambitious and visually impressive game in the portfolio. Most memory games treat sound as decoration. Signal Zen makes sound the entire puzzle. Players memorise musical sequences synthesised in real-time via AVAudioEngine - no audio files, just programmatic synthesis. Each hexagon has its own tone, and the sequences you memorise are genuinely musical.
The space theme draws from Close Encounters of the Third Kind - that iconic moment where communication happens through music, not words. A glowing hexagon centrepiece floats in space with particle effects drifting across a starfield. The opening animation rivals games with ten times the budget.
What makes it unique
The audio mechanic is genuinely rare on mobile. Most musical games are rhythm games trying to be Guitar Hero. Signal Zen is not competing with those at all. It sits in its own pocket of "musical puzzle" that barely has any competition.
Development timeline
Four days from concept to App Store submission, plus four days for App Store review. Eight days total from zero to live.
Technical highlights
AVAudioEngine for programmatic sound synthesis with zero audio files. CoreHaptics integration for tactile feedback. Particle effects and glow animations. Three difficulty modes for flow state, challenge, or relaxation.
Fledgling (In Development)
Bouncy baby bird landing
The fourth game in the portfolio, currently in active development. A cozy casual game where a fluffy baby bird learns to land. Players tilt their phone to guide the fledgling from nest to forest floor - no fail state, just bounce. Features the CHONK growth system (bigger bird equals higher bounce height but faster fall speed), procedural levels, and 100% procedural graphics with zero image files in the bundle.
Platform capability being tested
Gyroscope and accelerometer input via CoreMotion, physics simulation, and fully procedural graphic generation.
Technical highlights
CoreMotion accelerometer maps phone tilt to bird velocity. Xorshift64 algorithm creates infinite replayable content with date-seeded daily challenges. 6-layer parallax scrolling. Baby schema design principles (head 1.2x larger than body, large eyes placed low) to trigger "cute" response.

| Fledgling | Gyroscope, physics, procedural graphics |
The methodology behind this portfolio - agentic AI engineering with specs-first decomposition, reusable components, and persistent learnings - is the same approach applied to enterprise architecture, data modernisation strategies, and multi-agent AI pipelines. The domain changes. The discipline does not.
