Experience
2024 — now
Evinced
iOS Engineer, AI Championvia Sigma Software
I catch keyboard and missing-label bugs on iOS before a release, and I fixed Flutter accessibility in the engine so a cross-platform release could ship. I set up the workflow so a QA test case becomes a merged pull request in about 15 minutes, down from two to four days.
2023 — 2024
Bambuser
iOS Engineer, Scrum Mastervia Team In UA
L’Oréal and Hugo Boss run live shopping through Bambuser. I shipped the iOS features on Studio and the player SDK. During a show, the viewer sees the product, adds it to the cart, chats, and sends a reaction. About 40% of the role was Scrum Master for the iOS team.
2020 — 2023
TouchCast
iOS / macOS Developervia bMuse
Asking every guest to install Director was not going to work. They already had Zoom, so the host starts the session inside the macOS app and the guest appears on the virtual stage. I led that Zoom SDK integration, and the roadmap with Zoom’s SDK team.
2019 — 2020
Powercode
iOS Developer
I worked on the iOS apps for five products. My Pocket Therapist is a UK marketplace: a patient finds a therapist and joins an encrypted video session. Lessons is a tutoring marketplace for Danish students. Fantasty runs restaurant tables, orders, and the kitchen. Foodex24 is an online supermarket with a driver app. Level UP Ukraine was the conference app for 2019. I also started running technical interviews.
2016 — 2018
Mobius Software
iOS Developer
I built the iOS side of an IoT stack: MQTT, MQTT-SN, CoAP, and AMQP, and I ported the core library to Android (Java) and Qt. The products were a Bluetooth gateway with live dashboards, and an open-source MQTT client for IoTBroker.Cloud. That client connected to Amazon IoT, Azure IoT Hub, Google IoT Core, and DeviceWise.

ComeBack Mobility
Startup consultant · FDA-cleared BLE rehab device
Patients recovering from surgery were putting too much or too little weight on the leg. I built the iOS Bluetooth layer that pairs the phone to the crutch tips and draws the weight chart in real time. The company and Brueilly et al. 2024 report 73.6% compliance, against 21.1% in the control group.
2018 — 2019
Emotion Labs
Startup consultant · EMWatch BLE smartwatch
EMWatch was the first Ukrainian smartwatch to measure heart rate, blood pressure, steps, and sleep over Bluetooth. I built the iPhone app and the sync for about 20 signals, including the wellness recommendations, and I led the second version.
