Selected work

Three apps, live on the App Store.

01 — iOS App

Yoa Health & Workout Tracker

Turns Apple Watch, Garmin & Oura data into clear, friendly insights — sleep, recovery, strain & HRV. My biggest app.

  • SwiftUI
  • HealthKit

About this app

Yoa pulls data from Apple Health, Apple Watch, Garmin and Oura into one calm dashboard. It scores your sleep, recovery and daily strain, then turns them into plain-language guidance and a smart journal. The goal was to make health data feel encouraging instead of overwhelming.

02 — iOS App

Yoa: AI Food Calorie Tracker

Snap a photo of a meal and instantly see its nutrition — a gamified AI food scanner that makes logging effortless.

About this app

Point your camera at a meal and Yoa's AI estimates its calories and macros in seconds — no manual searching. Streaks and gentle nudges keep daily logging fun, and everything syncs back to Apple Health. I focused on making logging fast enough that people actually stick with it.

03 — iOS App

Zoe — Breathing Exercises

A playful breathing companion — Box Breathing, 4-7-8 and more, guided by Zoe the sloth. Calm, focus and better sleep.

  • SwiftUI
  • Animation

About this app

Zoe is a playful take on breathing and mindfulness, led by an animated sloth that breathes along with you. It covers Box Breathing, 4-7-8 and custom patterns for focus, calm or sleep, each with smooth haptics and motion. It's built to make a one-minute reset feel inviting rather than clinical.

End to end

I own the whole product.

Same person, the whole loop — from market research to App Store launch to the marketing that follows.

01 — Research

Find the gap

Mining Reddit threads, App Store reviews and competitor listings to validate the problem before a line of code is written.

  • Reddit
  • App Store
  • Surveys
02 — Design

Draw every pixel

Every icon, screen and App Store visual designed end to end so the build always matches the vision.

  • Figma
  • Photoshop
03 — Build

Ship the code

Swift & SwiftUI up front, React / Node / Spring Boot behind it, and Python for the ML pieces that earn their keep.

  • Swift
  • SwiftUI
  • React
  • Node
  • Spring Boot
  • Claude Code
  • Git
04 — Ship

Push to the store

App Store Connect, TestFlight betas, metadata, screenshots and review replies — every field handled.

  • App Store Connect
  • TestFlight
05 — Grow

Bring users in

Short-form video on TikTok & Instagram, paid campaigns on Meta & Reddit. The growth loop after launch is on me too.

  • TikTok
  • Instagram
  • DaVinci Resolve
  • Meta Ads
  • Reddit Ads

Right now I'm growing Yoa Health with short-form videos edited in DaVinci Resolve — follow along on TikTok and Instagram.

About

One person, the whole product.

I'm a senior full-stack developer at Deep Blue d.o.o. — and I treat every app I work on as mine to ship and grow. The same person scopes the idea, designs the UI in Figma & Photoshop, builds it in Swift / SwiftUI on a React, Node or Spring Boot back-end, then runs the organic short-form content and paid ads on Meta & Reddit that bring users in. Most of what I make lands in health and fitness because I live there too — I swim, run and play volleyball most weeks, which keeps the product honest to the people who actually use it.
