Work

Nine roles since I started in March 2014, newest first.

  1. 2026

    BeReal

    Senior iOS Engineer

    Memories squad

    One of a three-person squad behind Memories, Profile, Widgets and Recaps, in an app with about 40 million monthly users.

    I cut the Memories grid’s scroll hitches by about 30% and halved its startup hang, measured in Instruments. I traced about 20,000 crashes a week to a threading race in the data layer; the fix shipped and the crashes dropped. I built the two Memories widgets with the squad and began moving Recaps into its own modules.

  2. 2025

    Symphony

    Senior iOS Engineer

    I built the iOS app for an on-device photo curation proof of concept in about three months, as the only mobile engineer.

    It finds duplicates across a whole photo library, sorts travel photos into multiple categories and picks the ones worth keeping, all on the phone.

  3. 2025–now

    Infinum

    Senior iOS Engineer, contract

    One of two iOS engineers on a business banking app (NDA), covering payments and cards.

    I built its digital onboarding flow in SwiftUI; opening an account used to need a branch visit.

  4. 2020

    Insight Timer

    iOS Engineer, contract, part-time

    Hired directly to build the Home Screen widgets and the App Clip for a meditation app with over 30 million users, in about two months, just as iOS 14 introduced both.

    The widgets shipped in the iOS 14 launch window and are still in the app.

  5. 2020–23

    WillowTree

    Platform iOS Engineer, contract, part-time

    Live Oak team

    Three and a half years on WillowTree’s Live Oak team, looking after long-running apps for Virginia Lottery, Wyndham Rewards, Lidl, ClubCorp, Donatos and Potbelly.

    The work included two-factor login for Virginia Lottery and digital room keys for Wyndham Rewards.

  6. 2017–25

    Widex

    Senior Engineer, Tech Lead, then iOS Product Architect

    WS Audiology, through InScale

    Seven and a half years on Widex’s hearing-aid apps for iPhone and Apple Watch. I joined as a senior engineer, became iOS tech lead, then iOS product architect, and was technical lead of the iOS team as it grew to 15 engineers in five teams across Denmark, Germany, India and North Macedonia.

    I worked on Widex Moment from the start, a CES 2023 Innovation Awards honoree, and redesigned its iPhone and Apple Watch messaging as a generic layer that was later reused across the apps as a shared package.

    I led Widex Allure, the redesigned app for a new generation of hearing aids, from its start to release, and its move to feature modules, so teams could work in parallel and the next app could reuse them. I set code standards, mentored engineers, and built the hiring process with the chapter lead.

    “…guiding multiple development teams toward a shared vision.”

  7. 2017–now

    The Clic App

    Lead iOS Engineer, freelance, part-time

    A social app for making friends. I built it from the first commit in 2017 for its founder, Andrew McKay, when it was called Friendly.

    I’m still its only iOS developer, nine years on, and I’m moving it to SwiftUI and Swift Concurrency now.

  8. 2015–24

    Povio

    iOS Engineer, contract, part-time

    On and off for over eight years, brought in when a team needed an extra experienced engineer.

    Via Regalo, Hyperice, Bellabeat and Verbz.ai along the way. The last, in 2024, was one problem on a client app, Autobiographer: a swipeable chapter reader that lays long text out into pages, the way Apple Books does.

  9. 2014–17

    3P Development

    Intern, Junior, then Experienced iOS Engineer

    Where it started: intern in March 2014, Experienced iOS Engineer by October 2015. One of three iOS engineers, working directly with clients on calls and estimates from early on.

    I led the iOS work on client apps, including a ResearchKit cancer study for Mount Sinai through Thread, a Bluetooth diabetes dosage logger for Novo Nordisk, and iiStyle, a fashion app.

    I also won Startup Weekend Skopje in 2014, best mobile app and best UI/UX at Codefest 2015, and 3P’s S.T.A.R. Award.

    Patrick AinaCEO, iiStyle

    “His attention to detail immediately struck me.”
