Vladislav Ermachenkov

Lead developer for a new generation of ACS and Keyless Tags Architected and developed a scalable SDK/HAL for ACS devices based on ESP32-S3/C3 using C and FreeRTOS Took full ownership of the firmware codebase, collaborating directly with the CTO to define system architecture Implemented critical security features: Secure Boot and Flash Encryption Developed firmware for BLE key tags based on niche microcontrollers Created a Python-based GUI manufacturing tool

Developed FW for battery-powered cargo trackers (ESP32-C3, BLE 5.0), optimizing for ultra-low power consumption Designed a cross-platform architecture (UML) to support multiple hardware targets Introduced and configured a modern CI/CD pipeline using Docker and GitHub Actions, enabling automated cloud builds Implemented automated unit testing (Unity/CMock) and integration testing Mentored the team on transitioning to Jira workflows, code reviews, and proper documentation in Confluence

Rewrote the legacy build system to a cross-platform CMake + GCC solution for photo flash systems (EFR32BG13/22). Designed a firmware update architecture involving dual-microcontroller synchronization and integrated bootloaders. Developed Python-based automated test utilities for equipment validation.

Developed FW for Wi-Fi/BLE connected appliances using Qualcomm and NXP MCUs Successfully refactored the legacy make-based build system into a modular, cross-platform CMake solution, reducing build times and simplifying dependency management Designed and implemented HAL/OSAL to port libraries (LwIP, mbedTLS) across different hardware platforms Acted as a mentor for new hires: conducted technical interviews, onboarding, code reviews Collaborated with Qualcomm field engineers to resolve complex HW/SDK issues

Developed firmware for industrial IoT gateways and cosmetic devices (STM32, PIC, ESP8266). Implemented protocol stacks for M-Bus, eBus, and OpenTherm. Created drivers for various peripherals: GSM modems (SIM800), sensors, and displays. Designed schematics and PCBs (P-CAD) and performed hardware debugging using oscilloscopes and logic analyzers.

Developed firmware for industrial climate control systems (thermostats) using Microchip Microcontrollers. Implemented communication protocols: RS-485 and 1-Wire. Participated in hardware debugging and schematic design (P-CAD). Promotion: Promoted from Assembler role due to demonstration of engineering skills.

Assembly of industrial cabinets and sealed camera housings. Soldering, wiring, and functional testing of electronic devices. Relevance: Gained deep understanding of hardware reliability and physical constraints.
