We stabilize legacy systems, fix production issues, and
build reliable software that just works.
C++ and C# systems brought back under control. Reverse engineering, build recovery, CI/tests, and stabilization for mission-critical software that crashes in production or runs on tribal knowledge.
Reproducible builds even when the current state doesn't compile.
CI + tests scaffold before refactoring.
Memory correctness, performance hotspots, crash fixes.
We specialize in mission-critical systems where precision matters. From Windows and Linux ports to legacy rescue and BLE/mobile backends, we deliver expert solutions without bloated processes.
Small senior team (2–5)
Windows + Linux
Legacy rescue + porting
Hardware-adjacent systems
BLE mobile + backend
We take ownership of complex systems, from stabilizing legacy codebases to building reliable BLE-powered mobile apps and production-ready backend infrastructure, we focus on engineering that works in the real world. Our work is pragmatic, testable, and built for long-term maintainability — not short-term demos.
When your legacy system becomes a liability, we step in to regain control. We reverse-engineer undocumented code, clean up dependencies, restore build pipelines, and eliminate crashes, leaks, and performance bottlenecks.
Reverse engineering when docs are missing
Build recovery + dependency cleanup
CI pipeline + smoke tests + critical-path coverage
Memory errors/leaks, crashes, and performance bottlenecks
Windows → Linux porting when it reduces operational cost
We build robust BLE mobile applications designed to operate reliably under real-world connectivity constraints and device diversity.
Native connectivity layers with reliable reconnect patterns
Offline-first sync and background constraints handled
Multi-device support and a device test matrix
Firmware update flows: supported if needed, not primary
The infrastructure layer that keeps systems secure, observable, and production-ready.
APIs + auth + ingestion + admin portals
Monitoring/alerting + runbooks
Production-grade deployment posture
A defined SOP for inherited systems. Stability first. Modernization in slices.

Phase 4
We can't always show branding. We can show architecture, scale, and what we built.
What matters is the complexity we handled, the constraints we operated under, and the systems now running reliably in production. The proof is in the engineering decisions, stability under load, and long-term maintainability.
Manufacturing Systems
We built C++/Qt (QML) workstation applications controlling device programming, assembly, and QA workflows on the production floor. The system integrates serial and TCP tooling, supports 8+ barcode scanners, and ensures full traceability from PCB intake to lot assignment. Deployed across 3 programming stations (10 slots each) and 2 production lines, it processes ~5,000 devices per day.
Telemetry & IoT Platform
We delivered an IoT backend platform handling ~30,000 LoRa messages daily from 20,000 field collectors across Białystok and Łomża. The system includes ingestion and processing pipelines, along with management and user portals for access control and operational oversight. Built for reliability, scalability, and long-term field deployment.
Confidential Projects
We take on projects where we can make the biggest impact — and step back when it’s not the right fit.
Free triage provides a high-level review of your build, dependencies, repository structure, and risk register, with a clear recommendations for next steps.
