Engineering That Delivers in Production

From rescuing unstable legacy systems to building BLE-enabled mobile apps and full backend infrastructure — we take ownership and ship reliable software.

Legacy C++/C# Rescue
and Stabilization

We take over inherited systems that don't build, don't ship, and don't have documentation. Output is stable releases, repeatable builds, and an exit-ready handover.

Typical starting states

The reality before stabilization starts...

Doesn't compile
Doesn't build reliably

Stale dependencies
Irreproducible environments

No docs
Knowledge embedded in code

Memory leaks/errors
Crashes, performance collapse

High deployment cost
Windows lock-in

Deliverables

Concrete outputs that turn unstable codebases into controlled, production-ready systems.

  • Reproducible build environment
  • CI pipeline + smoke tests
  • System map + risk register
  • Stabilization release (crash/memory/perf)
  • Modernization/port plan (staged, rollback-safe)
  • Exit-ready handover (CI/tests/docs/runbooks)

Scoped modernization options

Staged, rollback-safe upgrade strategies aligned with real system constraints.
Focused improvements in stack, runtime, and deployment posture — without destabilizing what already works.

MFC / WxWidgets / older Qt
→ Qt 6 (Widgets or QML)

OpenGL modernization
1→2, 2→4

Legacy .NET web UI
→ Blazor

Windows → Linux porting to reduce licensing cost

Enable containerization where suitable

BLE/BT Mobile
(iOS + Android)

Connectivity that survives real devices: pairing/reconnect, background constraints, offline-first sync, and a device test matrix. We deliver production-grade BLE mobile applications built to handle real device fragmentation.

What you get

  • Native BLE layer + robust connection lifecycle
  • Offline queue + retry patterns
  • Multi-device framework approach
  • Device matrix testing plan and regression checklist
Boundary
  • Firmware update flows: supported if needed, not primary

Mobile Apps with Server Infrastructure

End-to-end delivery: mobile client, APIs, ingestion, admin tooling, monitoring, deployment.

Typical scope

  • API/auth + data model
  • Ingestion and processing pipelines (device-backed systems)
  • Admin portal + dashboards
  • Monitoring/alerting + runbooks
  • Deployment + maintenance plan

Deep Technical Expertise.
Zero Overhead.
