What we do?
Design and ship kernel-mode components with production discipline.
We build kernel drivers and OS-level integrations for reliability, performance, and security hardening when user-mode solutions are not enough. Compatibility, diagnostics, and safe upgrades are treated as core requirements.
Kernel work fails when teams chase power without operational safety. We focus on controlled execution and measurable outcomes.
- Unstable deployments caused by fragile kernel integrations
- Crashes and blue screens without a dump-first workflow
- Version drift across OS releases and driver signing constraints
- Invisible regressions without telemetry and baselines
- Performance bottlenecks at I/O and scheduling boundaries
- Security gaps from weak policy enforcement and unsafe defaults
- Support pain with poor docs and no reproducible debug plan
- Upgrade risk without rollback and compatibility strategy
Kernel engineering is about power and control.
What You Get
- Design docs and integration guidance with clear boundaries
- Signed, package-ready deliverables with rollout and rollback strategy
- Debug plan for dumps, ETW, postmortems, and triage workflows
- Compatibility strategy across OS versions and update cycles
- Performance baselines with before and after metrics
- Support-ready documentation and knowledge transfer
Stack and Use Cases
Windows Kernel
- KMDF, WDM, minifilters, device virtualization
- ETW instrumentation and low-overhead tracing
- Crash dump workflows and triage pipelines
- Signing, packaging, installer and update-safe design
Linux Kernel
- Kernel modules and platform integrations
- Performance profiling and regression baselines
- Observability and controlled eBPF usage when appropriate
- Compatibility strategies across kernel versions
Typical Use Cases
- Driver development for hardware, protocols, and custom devices
- File system and I/O control: policy enforcement and safe redirection
- Reliability hardening: crash reduction and fault isolation
- Latency work: p99 and p99.9 improvements with clear metrics
Security Hardening
- Integrity monitoring and attack surface reduction
- Safe defaults and policy enforcement
- Threat modeling when the deployment requires it
- Telemetry for detection and forensic readiness
