TESTIMONIALS

Check out the comment section!

Here's a bit of what I've been working on:

Pelvis Explorer 3D

This anatomy app was built in Unity for an experienced chiropractor. The biggest challenge was fine-tuning the camera controls while keeping object movement intuitive and smooth. Balancing real-time interaction with anatomical accuracy made this a rewarding technical and design exercise.

🦴 Cut and rearranged the 3D mesh in Blender

🎮 Camera rotation with smooth transitions and zoom functionality

🔄 Enabled switching between bone movement and rotation modes

↩️ Added reset and undo actions

🧭 Integrated interactive 2D UI arrows

Deadline Tracker

This app was built in Flutter to keep track of all the little (but important) deadlines we tend to forget: passport renewals, insurance expirations, or upcoming contract ends. Deadline Tracker lets you store documents with titles, expiration dates, and optional reminders to keep everything on track.

📁 Built a local database to store all document data

🔧 Implemented core functions for adding, editing, and deleting entries

📋 Developed the main list view and detail screen with a consistent UI layout

Rage Diary

I brought my original idea to life in Compose to turn unfiltered fury into fleeting pixels. It's not about productivity or self-improvement. With 3 cathartic tools - writing, burning, and screaming - it helps users let it all out, then let go.


🧾 Designed a simple text entry screen with automatic content deletion on app close

🔥 Created a flexible photoframe with sprite animation and audio effects

📢 Connected a decibel meter to a live visual feedback system for sound detection

🎛️ Coordinated all screens with a smooth, consistent UI flow

🛠️ Debugged thoroughly to keep the app stable and crash-free across different devices

Tip Calculator

This app was born in Jetpack Compose to solve a real problem I kept running into: some local restaurants add a service charge, but it's not always clear how much extra you’re paying. I created a quick, lightweight calculator to help estimate the full cost of a meal. Turns out, it’s just as useful for any kind of hidden fee!

🎨 Gave the app a visual refresh by changing the default theme

🧮 Wrote custom functions for precise calculations

📲 Implemented swipe gestures for seamless navigation between screens

    I needed a specialized program built exactly to order. My request wasn’t easy, as it involved a very narrow field of medicine. I spent a long time looking for someone who could not only understand the scope of the subject but also had the programming and design skills to actually pull off what I was asking for.

    Justyna handled the anatomical and biomechanical details alone. I barely had to explain anything. She even joked that she learned even more thanks to that. I expected the project to take her at least a month and a half, but she delivered a fully working program in just two weeks, including revisions - because, to be honest, I made the job even harder by asking her to add a more complex model once I saw how well she was doing.

    Her program runs flawlessly and aligns perfectly with the anatomical accuracy I was aiming for. I’m seriously impressed by her professionalism, her positive attitude toward the project, her willingness to really dig into the subject matter she’s working on, and of course, her solid grasp of app development.

    Highly recommended, and I’ll definitely be working with her again in the future.

Can one build an app with AI (Without Coding)? Yes! - But here's why you probably shouldn’t

With tools like ChatGPT, Claude, and Grok 2.0, almost anyone can throw together a basic app in minutes. To-do list with custom features? AI can write that for you.
