Experience

Embedded Software Engineer

2022 — 2026

Inovatyvi Medicina — medical robotics (endovascular surgery)

  • —Architected and developed from scratch the firmware for a remote indeflator device for angioplasty and stent placement, written to MISRA C++:2023 and documented in accordance with IEC 62304 — the device received its CE mark and is used in hospitals today.
  • —Developed firmware for an endovascular surgical robot (real-time, safety-critical motion control).
  • —Led a small team of junior engineers: owned CI/CD pipelines, Git workflow, code review culture, and coding standards across the firmware codebase.
  • —Built C++/Qt desktop applications supporting the devices.
  • —Designed the network architecture for the robot. Architected and enabled remote robot operations over a custom VPN network.

Embedded Software Engineer / iOS Developer

2019 — 2022

Voltas IT — OBDeleven automotive diagnostics (consumer IoT)

  • —One of the first engineers on the OBDeleven iOS app, building the app used by drivers worldwide for vehicle diagnostics, coding, and customization.
  • —Developed firmware for the OBDeleven OBD-II dongle — a BLE gateway between the mobile app and the car's control units.
  • —Worked across the full product chain: firmware, BLE communication, and the iOS app consuming it.

Software Developer

2017 — 2019

Singleton Labs — smart parcel box (consumer IoT)

  • —Started in Android development, transitioned to iOS (Swift), then to firmware: developed Nordic nRF firmware in C for a BLE-controlled lock for a smart post box.
