ClockMatter
Systems software where timing meets the physical world.
Writing and engineering work by Alexander Krivolapov — Senior Software Engineer working across database internals, embedded and hard real-time systems, storage, platform portability, hardware/software integration, and low-level systems programming in C.
Database systems
Embedded & real-time
Systems programming in C
01
Areas of work
Long-term systems engineering at the boundary between software, operating systems, storage, and hardware.
Embedded & hard real-time
Bare-metal and RTOS environments, timing-sensitive systems, embedded architectures, storage devices, peripheral interfaces, and hardware-facing layers.
Storage & persistence
Custom data storage, data indexing, raw flash, file systems, device drivers, compression, encryption, and platform-specific I/O.
Systems programming in C
Hands-on production C close to operating systems, hardware, storage, runtime layers, and performance-critical code paths.
Portability & integration
Cross-platform ports, toolchains, embedded hardware/software integration, architecture-specific behavior, debugging, and JTAG.
Complex systems troubleshooting
Root-cause analysis across the DBMS, OS, compiler/toolchain, file system, drivers, hardware, client integration, and production code.
02
Writing
Selected published work. Future technical notes and articles will live here as ClockMatter grows.

Real-Time Database Management on Raw Flash: Eliminating Complex Infrastructure and Simplifying Drivers
Hard real-time database management on raw flash, with attention to deterministic latency, flash management, platform drivers, STM32, FreeRTOS, and portability.
03
Selected technical work
Representative areas rather than a résumé timeline.
eXtremeDB
Core database architecture and implementation
Long-term work on a commercial embedded database engine, including custom memory management, indexing, storage and file-system access, synchronization, transactions, event handling, platform services, APIs, and compatibility-sensitive product evolution.
Platforms
Embedded and RTOS portability
Porting and maintaining systems software across bare metal, Linux/Embedded Linux, RTOS environments, ARM and other architectures, storage devices, peripheral interfaces, compilers, and toolchains.
Diagnostics
System-level root-cause analysis
Reproducing failures, analyzing logs and core dumps, debugging and profiling at system level, and isolating problems that may sit in the DBMS, OS, toolchain, file system, drivers, hardware, or client integration.
Engineering practice
Tooling, technical leadership, and consulting
Developer tooling, code generators, build/release systems, release planning, mentoring, technical interviewing, customer engineering engagements, and hands-on production fixes.
