I typically get involved when:
  • systems fail under real-world conditions
  • internal teams cannot resolve critical issues
  • legacy systems become a bottleneck
  • undocumented or poorly designed systems must be fixed
  • integration between hardware and software breaks down
  • stability and reliability become business-critical
What I do:
  • Take over complex and problematic systems and bring them to stable operation
  • Modernize legacy industrial and embedded software
  • Debug and resolve hard-to-reproduce issues
  • Integrate hardware, low-level software and external systems
  • Improve performance, reliability and maintainability
  • Provide long-term technical ownership if required
Key expertise:
  • Reverse engineering of software, protocols and undocumented systems
  • Deep debugging of complex, unstable environments
  • Embedded systems (bare metal and Linux)
  • Hardware–software interaction and low-level integration
  • Industrial systems and automation
  • Computer vision in production environments
Selected Projects
Examples of complex industrial and embedded systems I have worked on, focusing on stability, performance and real-world constraints.
Pharmaceutical Serialization System (Data Matrix Codes)
Problem:
High-speed production required reliable and accurate scanning of serialized codes across heterogeneous hardware.
Action:
  • developed machine vision software for ARM Linux and Windows
  • integrated industrial cameras from 4 different vendors
  • ported solution across multiple hardware platforms
  • optimized processing pipeline for high-throughput environment
Result:
  • Achieved stable performance up to 400 codes per second in real production conditions.
Critical Recovery of Large-Scale Display System (International Event)
Problem:
Failure of a large-scale display before a high-visibility international event.
Action:
  • designed and implemented custom hardware interface
  • restored controller firmware
  • fixed system under strict time constraints
Result:
  • Restored system operation and prevented major reputational and operational failure.
Industrial Marking System (Embedded Linux)
Problem:
Existing system required stability improvements and functional expansion under production constraints with switch to new hardware.
Action:
  • took over existing ARM Linux codebase
  • implemented new functionality
  • performed refactoring and issue resolution
  • supported deployment and production operation
Result:
  • Improved system stability and enabled reliable long-term operation in production environment.
Robotic Congress & Automated Broadcasting System
Problem:
Manual control of multiple cameras and AV equipment required large operational effort and limited scalability.
Action:
  • developed control software for congress and broadcast system
  • implemented algorithms for coordinated control of robotic cameras
Result:
Enabled high-quality live broadcasting with a single operator.
Embedded safety system
Problem:
Required reliable control system for safety-critical environment.
Action:
  • designed system architecture
  • implemented bare-metal C++ software
  • designed and implemented sensor system
  • integrated with hardware components
Result:
  • Delivered stable and predictable system behavior under critical conditions.
Machine Vision System (Reverse Engineering)
Problem:
Third-party vision system required adaptation without full documentation.
Action:
  • reverse engineered software components
  • restored and adapted functionality
  • integrated into target system
Result:
  • Enabled continued operation and integration of the vision system.
How I work

Initial assessment

Quick understanding of the problem, constraints and risks.
Deep analysis
System-level investigation: code, architecture, hardware.
Solution strategy
Clear approach focused on risk reduction and stability.
Execution
Focused implementation with minimal disruption to operations.
Follow-up
Support and further improvements if needed.
Engagement model
  • Independent expert engagement
    Direct collaboration without unnecessary overhead.
  • Project-based work
    Clear scope and responsibility for results.
  • Critical problem solving
    Fast involvement in urgent or complex situations.
  • Long-term technical support
    Ongoing system ownership and development.
Support for international vendors operating in Russia
  • local engineering presence for deployed systems
  • troubleshooting when remote support is not sufficient
  • acting as a technical bridge between local teams and HQ
  • system recovery in case of missing or limited vendor support
  • adaptation to local technical and operational constraints
If you have a complex system that requires deep technical expertise — let’s discuss your case.
