I run LC++ Łukasz Czerwiński, a one-person engineering consultancy focused on high-performance C++ systems,
deterministic architectures, and low-latency design. For more than a decade I've been building trading infrastructure,
matching engines, market data pipelines, and mission-critical backend systems where reliability, clarity, and
performance are non-negotiable.
LC++ is my personal craft brand: I design, implement, and refine systems with a strong emphasis on architectural purity,
explicit ownership, cache-friendly data layouts, and zero-overhead abstractions. I help companies diagnose bottlenecks,
redesign core components, and build software that behaves predictably under load.
Whether it's a custom product, a performance audit, or long-term technical consulting, LC++ delivers engineering work
that is precise, transparent, and built to last.
I am a proud member of Mensa Poland.
Design and implementation of custom data structures optimized for locality, cache behavior, and explicit ownership. LC++ delivers deterministic trees, allocators, containers, and memory layouts tailored to real-time workloads and performance-critical systems.
Development and refinement of algorithms where latency, throughput, and predictability matter. LC++ focuses on branchless logic, cache-aware processing, and zero-overhead abstractions. I help clients diagnose bottlenecks, eliminate accidental complexity, and achieve stable performance under load.
Architecture and implementation of matching engines, order-handling pipelines, and market-data components. LC++ provides deterministic event processing, predictable latency behavior, and clean, maintainable designs suitable for trading systems and other real-time environments.
Long-term or on-demand consulting for teams that need clarity, structure, and engineering discipline. LC++ supports modernization of legacy codebases, redesign of critical components, and strategic guidance for systems where correctness and performance are equally important.
