SUMMARY
Software engineer with 5 years of commercial experience building high-performance mobile applications in Kotlin, now
moving into embedded systems. Commercial work has consistently involved the hardware layer — BLE beacon discovery
(AltBeacon), NFC tag reading, geofencing, sensor and camera pipelines — alongside concurrency, offline-first data handling
and memory/performance optimization on resource-constrained devices. Currently building firmware in C/C++ on ESP32 and
Arduino: sensor integration over I2C/SPI/UART, WiFi connectivity, and circuit prototyping including schematic design,
breadboarding and soldering. MSc in Informatics and MSc in System Analysis.

EXPERIENCE

Embedded Development Student — Beetroot Academy + hands-on personal projects
July 2026 — Present | Team size: 15
• Developing firmware in C/C++ for ESP32 and Arduino microcontrollers, building a WiFi-connected IoT sensor node that
collects environmental data and publishes it to a remote endpoint
• Integrating peripheral sensors and modules over I2C, SPI and UART; working with ADC readings, PWM control, GPIO
configuration
• Designing and assembling hardware prototypes end to end: breadboarding, soldering, power management and
debugging via multimeter and serial logging
Tech: C, C++, ESP32, Arduino, I2C, SPI, UART, ADC, PWM, PlatformIO, Git

Android Engineer — Inventrip (Travel & Tourism Guide) — Customer: Europe
August 2023 — Present | Team size: 3
• Built a travel application with 100k+ downloads, integrating hardware capabilities directly: Bluetooth beacon
(AltBeacon/BLE) discovery, NFC tag reading and custom foreground geofencing
• Designed an offline-first architecture with Mapbox SDK geographic data (GeoJSON) and Room local storage, so the device
operates reliably without connectivity
• Implemented camera and on-device processing pipelines (CameraX, ML Kit) and background task scheduling with
WorkManager
• Architected the platform using Clean Architecture and the repository pattern with a hybrid Jetpack Compose / XML UI
• Handled requirements analysis, feature development, unit and integration testing, code review, API documentation, build
configuration and Play Store deployment
Tech: Kotlin, Jetpack Compose, Coroutines, Flow, Dagger Hilt, Mapbox SDK, Room, DataStore, ExoPlayer, WorkManager, CameraX,
ML Kit, AltBeacon (BLE), NFC, Retrofit, Firebase, Timber

Android Engineer — Crypto Wallet — Customer: Europe
December 2023 — June 2024 (6 months) | Solo developer
• Developed a cryptocurrency management application with secure wallet functionality using industry-standard encryption
to protect user funds
• Integrated real-time market data via REST API and implemented reactive data flows with Coroutines and Flow to improve
responsiveness

• Migrated legacy components to Dagger Hilt, reducing boilerplate, and built a portfolio tracking interface in Jetpack
Compose
• Owned the full cycle solo: requirements, development, testing, build configuration and deployment scripts
Tech: Kotlin, REST API, Retrofit, Dagger Hilt, Coroutines, Flow, MVP, JUnit4, Espresso, Gradle, Git, Jetpack Compose

Android Engineer — Expedia / Vrbo (Vacation Rental Marketplace) — Customer: USA / Europe / Asia
August 2021 — October 2023 (2 years, 2 months) | Team size: 4–6
• Developed and maintained features for a vacation rental platform serving 500K+ active users across three continents
• Optimized application performance, reducing load times and memory usage on constrained devices
• Implemented advanced filtering and comparison tooling, and designed a tripboard feature for tracking rental options
• Collaborated with cross-functional teams to integrate designs with backend systems; participated in code review and API
documentation
Tech: Kotlin, Apollo GraphQL, Retrofit, Coroutines, Dagger, MVP, JUnit4, Espresso, Gradle, Git, Jetpack Compose
