Custom Windows / Native / .NET Security Development
C++ • C# • .NET • Reverse Engineering • Binary Protection • Licensing • Drivers • Hypervisors
Looking for specialised Windows, native or .NET development?
I take on custom projects ranging from smaller reverse engineering jobs through to complete security platforms, native/.NET protection systems, kernel components and virtualisation-based tooling.
Everything is developed around the actual project rather than forcing an existing generic codebase onto your requirements.
Development Services
- C / C++ Development — native applications, DLLs, SDKs, libraries and supporting infrastructure
- C# / .NET Development — applications, libraries, tooling, backend components, assembly processing and runtime systems
- Reverse Engineering — native and .NET binary analysis, undocumented behaviour, protocols, file formats and compatibility work
- Native Binary Protection — obfuscation, transformation, integrity systems, build mutation and anti-tamper mechanisms
- .NET Protection — IL transformation, control-flow protection, constants, strings, anti-tamper, metadata transformations and custom protection pipelines
- Licensing & Authentication — licensing servers, secure client SDKs, session handling, encrypted delivery and administration panels
- Secure Binary Delivery — authenticated module distribution, encrypted streaming, verification and controlled loading
- Windows Internals — processes, memory, PE internals, CLR/.NET internals, services, IPC, system APIs and low-level diagnostics
- Kernel Development — WDM/WDF drivers, communication layers, system instrumentation and specialised driver components
- Intel VT-x / EPT — custom hypervisors, VMX architecture, EPT-based instrumentation and research tooling
- Custom Security Tooling — internal tools, research platforms, diagnostics and specialised systems built around your requirements
Binary Protection & Licensing
For commercial native or .NET software I can build or integrate complete protection infrastructure rather than simply applying an existing packer.
- Per-build or per-customer binary mutation
- Native and .NET protection pipelines
- Encrypted binary delivery
- Integrity verification
- Authentication and licensing
- Secure update infrastructure
- Client SDK integration
- Backend APIs
- Administrative tooling
- Deployment and production setup
This can be delivered as either an integration into your existing infrastructure or as a complete self-hosted solution.
.NET / C# Work
- Assembly rewriting and transformation
- IL analysis and modification
- Obfuscation systems
- Control-flow transformations
- Constant and string protection
- Metadata transformation
- Anti-tamper systems
- Assembly loading and runtime tooling
- Deobfuscation and analysis tooling
- Custom build pipelines
- Native C++ / managed .NET interop
Reverse Engineering
Smaller RE jobs are welcome as well.
- Understanding undocumented native or .NET binary behaviour
- Recovering algorithms or data structures from software you are authorised to analyse
- Protocol and file-format analysis
- Compatibility research
- Crash and dump analysis
- Protected binary research
- .NET IL and metadata analysis
- Producing technical documentation from existing software
Hypervisor / Kernel Projects
I also take specialised low-level projects involving Windows kernel development and Intel virtualisation.
- Intel VMX setup and lifecycle
- EPT management
- VM-exit architecture
- Guest state handling
- Memory introspection
- Kernel telemetry and instrumentation
- Custom driver architecture
- Low-overhead research hypervisors
- Stability-focused production architecture
Code can include references to relevant Intel and Microsoft documentation where useful, particularly for clients who intend to maintain or extend the project themselves.
Example Pricing
Pricing depends entirely on scope. These are examples rather than fixed rates.
- Small reverse engineering / development task: €100–€250
- Custom C++ / C# component or integration: €200–€500
- .NET protection / transformation work: €250–€700+
- Licensing / secure delivery integration: €300–€700
- Native protection work: €300–€800+
- Custom driver development: €400–€1,000+
- Hypervisor development: €500–€1,500+
- Larger complete systems: quoted individually
I am happy to work around a realistic budget where the scope can be adjusted appropriately.
How Projects Work
- You explain what you need and provide any existing architecture or requirements
- I define the scope and quote the project
- Larger custom projects generally use staged payment
- You receive progress updates throughout development
- Source code is provided where included in the agreed scope
- I assist with initial integration and setup after delivery
I prefer understanding the actual use case before quoting so the project can be scoped properly around what you actually need.
