About Me

I’m an iOS-first engineer with an electrical engineering background, which means I love pairing polished SwiftUI interfaces with rock-solid systems thinking. I’ve shipped multiple iOS apps to the App Store, run my own beta programs, and nerd out over everything from App Store screenshots to launch-day analytics.

I specialize at the intersection of iOS development, backend logic, and system design.

My stack:

  • SwiftUI / UIKit
  • Swift Testing
  • Combine / async-await
  • Core Bluetooth / Core Motion
  • Vision Framework
  • Python
  • Java
  • Linux / Bash
  • API Design
  • Kubernetes

Image to PDF: File Scanner

I set out to build a document scanning app that could rival CamScanner. What started as a simple idea quickly evolved into a technically challenging but rewarding project. The result was Image To PDF: File Scanner, a lightweight yet powerful tool for turning handwriting and documents into shareable digital files. In the process, I gained hands-on experience with Vision Framework and various techniques to manipulate images.

ChallengeCreate one of the best document scanning experiences

OutcomeThe app reached over 1,000 downloads across 30+ countries with zero crashes, 3.4 sessions per active device, and 82% of traffic from App Store search.

  • Crop, apply filters, signatures, and watermarks.
  • Leveraged ChatGPT API to translate contents of document/s to 20+ languages.
  • Export results in JPG/PDF or save to Photos.
  • Utilized Google AdMob for monetization with lightweight, non-intrusive banner and interstitial ads.

TimeDive: Guess Year & Place

A multiplayer trivia game inspired by GeoGuessr, where players compete to guess the year and location of historical photos in fast-paced rounds. Designed as a fun, social experience with high replay value.

RoleiOS Engineer (collaborated with a UX designer)

ChallengeCreate an engaging, fast-paced multiplayer game that blends historical discovery with competitive gameplay.

OutcomeLaunched on the App Store with 265 downloads across 5+ countries, 2.7 sessions per active device, and 63% organic discovery via App Store Search.

  • Players can host or join tournaments and compete. A live ranking leaderboard updates at the end of each round.
  • Dynamically loads curated content packs without requiring App Store resubmission, enabling fast iteration and new photo sets.
  • Integrated Core Haptics and subtle color grading to draw attention to revealing image details and enhance immersion.
  • Worked alongside UX designers to build an intuitive and visually appealing interface optimized for mobile trivia gameplay.

BLE Control: iOS ↔ Raspberry Pi

I was curious about how devices like Oura and Whoop use BLE to communicate with iPhones, I set out to learn Core Bluetooth and understand the end-to-end communication process myself.

RoleiOS Engineer

ChallengeUnderstand how BLE devices like Oura and Whoop communicate with iPhones.

OutcomeCreated a working iOS app that reliably toggles GPIO pins on a Raspberry Pi over BLE.

  • Wrote a Node.js script that acted as the BLE peripheral, exposing custom services and characteristics for the iPhone to interact with.
  • Built a SwiftUI app that allowed the user to select a GPIO pin and toggle it on or off.

RoleiOS Engineer

ChallengeCreate an app that track tasks, ideas, and journal entries and visualizes task completion with Swift Charts.

OutcomeApp Store stats: 6.2K impressions, 73 total downloads, 1.42% conversion rate.

  • Created projects to group related tasks and ideas that are within the same context.
  • Journaling with optional daily photos allows users to reflect and capture life moments.
  • Swift Charts power beautiful graphs for task completion, backlog aging, and neglected goal detection.

  • Leverage GitLab and Collaborator for branching strategies, code reviews, and CI pipelines.
  • Participate in daily scrums, retrospectives, and estimation to keep delivery on track.

Other Projects

Curated snapshots of experiments and collaborations I’m proud of.

Senior Design Project

Led a four-person team to design a modular drone for mock disaster response. I owned the Raspberry Pi + Pixhawk stack, writing Python scripts that combined pre-recorded flight plans with object detection and geo-fencing so the drone could safely fly indoor demos. The prototype executed 15-minute autonomous runs and streamed telemetry for our sponsors to review.

Designed and coded this site, then deployed it on my Raspberry Pi cluster using NGINX, Docker, and dynamic DNS.

Posture Pod (Discontinued)

Explored the capabilities of AirPods sensors by building an unpublished iOS app that tracks my posture while coding. Used Core Motion data to monitor head tilt and developed a posture scoring system to help prevent long term back and neck issues. Built it to understand what real time AirPods data could enable for future wellness and productivity tools.
