01Selected work
Things I’ve built. Most of them in real use.
In the order I’m proudest of them — from an app 186,000 people have downloaded, to the tools I built for my team, a friend and my girlfriend.
RideCheck
iOS · Android · Web — 2025 to now
Know every part.
Trust every ride.
A vehicle-care app that logs every trip on its own and tells riders what needs servicing before it fails. Built at the Apple Developer Academy, scaled at the Apple Developer Institute, with me as Head of Product.

iOS · Photo editorIn progress
RideLens
A photo editor made for cars. It finds the car on its own, lights it apart from the scene, hides the plate, and puts posters and stickers behind it. Part of the RideCheck family.
Web · RideCheck internalUsed daily
Waypoint
Our team’s Notion and Jira in one; I built most of it. Paste a bug, an idea or a rant, and Claude labels it, maps it to the product and turns it into tasks.
Web · Django2024
Reporthink Editor
My internship project at Mediawave, and my thesis: download-only report templates turned into a live editor — edit, reorder pages, export to PDF. Where I found out I like writing code.
Web · JournalA friend uses it too
A place to rant
I built it in a slump, when I needed somewhere to put everything. I shared it with a friend in the same spot, and it helped him too. When you’re ready, any AI turns the entries into a chapter: mood, themes, patterns.
AndroidMade for my girlfriend
YT Playlist Downloader
She had a problem, so I solved it. Share a YouTube playlist and every song lands on her phone, skipping what she already has and tagged so Samsung Music shows it properly.
Web · PDF exportNo paywall
CV Maker
Online CV makers let you design the whole thing, then charge you to download it. So I built my own: one clean template, a design panel and a real PDF at the end.
02Apple Developer Academy
Where I learned to ship.
RideCheck started at the Academy in 2025. These came from the same year: a Mac app on the App Store, a party game on TestFlight, my first UI/UX exercise, and an on-device AI experiment.
macOS app2025
SwiSekai
An “isekai” for learning Swift — a quest map of lessons, quizzes and projects with an AI mentor at your side. Live on the Mac App Store.
iOS game2025
BomBocLat
Pixel-art hot potato. Pass the bomb before a hidden timer runs out — built to get a new cohort talking.
UI/UX · FigmaDesign exercise
Recipe App
My first UI/UX exercise at the Academy: a Figma-only recipe app that starts from what’s already in your kitchen.
iPadOS · MLXShelved
AI Journal
A private journal with a language model that runs entirely on the iPad. I shelved it; the idea lives on in A place to rant.
03The workshop
Things I built because I wanted them to exist.
Smaller tools I made for myself, and most of them are still in daily use. Each one has a short write-up.
MUOOD
macOS · Old phones
Making Use Of Old Device: the phone in your drawer becomes a live companion screen for your Mac. Now playing with synced lyrics, a deck of buttons, Mac controls, vitals, repos and deploys, weather and a clock. Apple’s StandBy, if StandBy did a lot more — over USB or Wi-Fi.
Filter Generator
Desktop · Python
Drag in a pile of photos, dial in a film look — warmth, fade, grain, glow — and it batches them all out. It came from an aha moment: an image is just numbers arranged so our eyes read a picture, and numbers are something I can change with code.
Photo Widget
iOS · WidgetKit
Apple’s photo widget won’t let me pick the one picture I want, and the App Store alternatives come with ads or a paywall. So I built my own: my photos, my crop, on a schedule I choose.
Void
Browser homepage
The new tab page I actually wanted: a clock, search, the links I use, notes, tasks and a focus timer, over a background with particles and depth. No build step, no dependencies, no accounts — my settings, notes and tasks stay in the browser.

Where I’ve been building.

05About
Engineer by training. Product person by habit.
I studied Software Engineering at Universitas Prasetiya Mulya, spent 2025 at the Apple Developer Academy in Bali shipping apps with small multicultural teams, and in 2026 helped take RideCheck through the Apple Developer Institute — from one platform to three.
I care about the details people feel but rarely notice: the battery a background task doesn’t drain, the animation that makes a number believable, the empty state that isn’t an apology.
