Software, databases, and digital electronics engineered for your success.
We design and deploy scalable travel reservation engines (ERS / EMS), accelerate high-concurrency SQL databases, build custom enterprise web applications, and engineer miniature DCC electronics and decoders for model railways.
We have been engineering software and electronics long before it became a trend.
Now that you found us, your search is over. MATRIX SOFT Karol Marcińczak represents over 20 years of direct engineering experience at the intersection of high-concurrency backend software, relational databases, and precision digital hardware.
Unlike corporate agencies or anonymous software houses, with MATRIX SOFT you collaborate directly with the principal architect and engineer. No account managers, no broken handoffs — just authentic technical clarity, precision, and personal commitment to your goals.

Whether you need a high-throughput travel booking engine, query optimization for a massive database, or a miniature DCC train decoder — we deliver solutions of the highest caliber.
Travel Reservation Systems (ERS / EMS)
Turnkey booking engines for tour operators, travel agencies, and dynamic online portals.
- ERS & EMS Architecture — full booking workflow from search and margin calculation to automated ticketing.
- Bidirectional API / XML connectivity with GDS hubs, airlines, and global hotel aggregators.
- Dynamic packaging (flight + hotel) with real-time inventory and pricing calculations.
- Yield management algorithms and high-speed caching protecting servers during seasonal spikes.
Database Architecture & SQL Optimization
Design, tuning, and ongoing maintenance of mission-critical relational database architectures.
- SQL Query Optimization — bottleneck profiling, indexing strategies, and table partitioning.
- OLTP transactional schemas for heavy concurrency and analytical OLAP data marts.
- ETL streaming pipelines and zero-downtime migrations for massive datasets.
- High availability (HA), automated replication, failover strategy, and disaster recovery.
Custom Software & IT Services
Bespoke web applications, e-commerce integrations, and comprehensive business workflow automation.
- Custom B2B / B2C web applications tailored to your specific commercial workflows.
- System integrations — e-commerce platforms (PrestaShop), ERP systems, CRM, and logistics APIs.
- Code audits and modernization of legacy software to PHP 8.2 / 8.4 standards.
- Infrastructure management: Linux/FreeBSD, Nginx, Apache, and Redis/Memcached caching.
Model Railway Electronics Design
Custom circuit design, compact PCB layout, and real-time firmware for DCC digital model railways.
- NMRA DCC Digital Control — custom locomotive motor controllers, function, and sound decoders.
- Compact multi-layer PCB design precisely fitted for H0, TT, and N scale locomotives.
- Real-time embedded firmware (C/C++) for STM32, ESP32, and AVR microcontrollers.
- Layout automation — RailCom, LocoNet, S88 feedback buses, reverse loop modules, and signal controllers.
