I build Android apps that solve real problems
I am Rafael, a self-taught Android developer with more than 5 years building applications. I care about what people use every single day: tracking expenses, car paperwork, scanning a code without friction.
My apps on Google Play
Each one started from something I needed myself. All of them are published and actively maintained.
InfoAuto Auto & Vehicles
Vehicle inspection, driving restrictions and traffic fines: everything you need to know about your car, in a single app.
Mi Dinero – Personal Finance Finance
Your finances on your phone: track income and expenses, keep an eye on installment purchases and never miss a payment again.
QRfyum – QR code scanner Tools
Scan, save and share QR and barcodes in seconds, using your camera or an image from your gallery.
MiniMind Games · Puzzle
Eight short minigames to train logic, memory, math, attention and reflexes. Ad-free and fully offline.
Passbox – Password manager Tools
Keep the passwords for all your accounts in one place and find them the moment you need them.
Passionate about technology, self-taught by conviction
I have been building for Android for more than 5 years. I learned on my own, by building and shipping: every app in this portfolio came from a problem in front of me that nobody had solved the way I wanted.
I like software that gets to the point: opens fast, does not ask for permissions it does not need, and does what it promises. If one of my apps is useful to you, a review on Google Play goes a long way toward keeping them improving.
I work with Android · Kotlin · Java · Jetpack Compose · Material Design · SQLite / Room · Firebase · Google Play Console

Simple before complete
I would rather ship an app that does three things well than one that does thirty halfway.
-
Your data is yours
I request the minimum permissions and spell out in every policy what is stored and where.
-
Built for real phones
I optimize for mid-range devices, which is what most of us actually carry.
Let's talk
If you hit a problem with one of my apps, have an idea to improve them, or just want to say hi, drop me a line. I reply to every email.
