PROFILE
Test Engineer with 4+ years of experience in hardware testing, firmware validation, and test automation. Validated motion and security
sensors across 30+ physical devices: environmental stress tests, RF link-quality testing, siren SPL measurements, firmware regression, and
compliance testing (EN 50131, PD 6662, IP66). Embedded background: designed a device PCB and wrote ESP32/STM8 firmware (C/C++).
Built a UAV test suite in Python and pytest: 60 automated tests of ArduPilot flight-controller behavior over MAVLink (failsafe, geofence,
missions, telemetry) in SITL, with CI and Allure reporting. Seeking a UAV Systems Test Engineer role in embedded and hardware testing.

PROJECTS
UAV SITL Test Suite (Python, pytest, pymavlink, ArduPilot SITL, Allure, GitHub Actions)
60 automated tests for flight-controller behavior (failsafe, geofence, missions, telemetry) with CI and Allure reports.

HIL Test Stand (ESP32-S3, C++, pytest, pyserial)
Firmware and host test framework for powering, measuring and controlling a DUT over a text protocol (in progress).

Power & Test Interface Board (KiCad, ESP32-S3, INA219)
PCB design for a USB-powered DUT test interface: switched power, current measurement, UART and reset/boot control (design stage).

EXPERIENCE
TheCoder | Dentelo (France) Remote
General QA Engineer | Test Lead Jul 2025 – Present
• Built a modular API/ UI/mobile automation framework from scratch (Java, RestAssured, Selenide, Appium) covering 83% of critical
scenarios; regression time reduced from 5 days to ~20 hours;
• Integrated tests into GitHub Actions CI with Allure reporting; added JMeter load tests and API security checks (JWT, OAuth2);
• Implemented a custom test script that uses SSH to verify the results of parsing and web scraping;
• Coordinated a Junior QA and established testing processes and documentation.

YouControl Remote
Middle General QA Engineer Feb 2025 – Mar 2026
• Completely rewrote and updated ~97% (~1,700) of REST API automated tests (Java, RestAssured, CodeX) and refactored ~62% (806+ out
of 1,300) of web application tests, ensuring robust regression coverage of the Core Team's key business flows;
• Optimized CI/CD pipelines by configuring test parallelization and refining retry mechanisms, reducing overall regression execution time
by 35% (from 10 to 6.5 hours);
• Implemented programmatic validation of data integrity and system states directly at the database level utilizing MongoDB pipelines

Ajax Systems Kyiv, On-Site
Manual QA Engineer Jan 2024 – Feb 2025
• Tested 15+ new hardware revisions of motion and security sensors (QA R&R Team), validating firmware behavior across device iterations;
• Validated radio protocol stability and the system core (QA Core & RS Team); found and documented ~20 critical defects before release;
• Ran functional and regression testing on video modules and PIR motion sensors across 30+ physical devices;
• Ran lab validation of sensors and firmware: environmental stress tests in a climatic chamber (temperature cycling, low/high temperature
operation) and siren sound pressure (SPL) measurements against loudness requirements;
• Tested radio link quality in RF lab conditions (signal strength, packet loss, range and stability between devices and the hub) under varying
distances and interference;
• Performed compliance and hardware validation per PD6662, EN 50131, EN 50131-2-2, IP66;

• Developed automated BDD tests for sensor stability, cutting regression time from ~17 days to 10–14 days.

Noosphere Kyiv
Software Engineer (Embedded & Mobile) / QA Engineer Apr 2022 – Sep 2024
• Designed the device PCB (schematic and layout) and supported hardware bring-up of the prototype;
• Built an Android app (Java, Kotlin) for remote device control; implemented BLE communication and later migrated the connection to Wi-
Fi, keeping the transport layer abstracted from business logic (~72% unit-test coverage of core logic);
• Developed ESP32 firmware (C/C++) with a custom Test Mode, cutting defect diagnostic time from ~24 hours to 1-3 hours;
• Set up the MVP testing lifecycle from scratch (test plans, test cases): zero critical defects in production during the first 3 months
