[DEV] I BUILD WHAT YOU CAN'T BUY: FULL SOURCE CODE & RIGHTS | DEOBFUSCATION TOO!

I build custom tools, platforms, and protection systems for developers who distribute native software and game modifications. I work in C++, Python, and C#. I deliver source code. You own what you pay for.

If you need something that does not exist, or you need something that exists but you want to own it instead of rent it, I build it.

What I Can Build (not limited to, will research for you)

License & Authentication Systems

• HWID-based key activation with session heartbeats
• Cross-license device banning
• Admin panel with license lifecycle management
• Reseller portals with credit quotas
• User self-service dashboards
• Server-side binary delivery (encrypted, memory-only mapping)
• Remote instruction execution (sandboxed compute offload)

Binary Tools & PE Manipulation

• Instruction-level mutation engines (x86/x64, no virtualization)
• Container mutation: section renaming, timestamp shifting, debug stripping
• Per-build watermarking for leak tracing
• Import table scrambling and IAT cleanup
• Server-side PE loaders that build flat images and strip headers
• Custom manual map stubs for usermode and kernel-mode loading

Python Protection & Hardening

• Anti-debug integration for Python processes
• Memory protection against external dumps
• Source encryption at rest with runtime decryption
• String literal encryption with per-string AES
• Import obfuscation and dynamic resolution
• Source cleanup: docstring stripping, comment removal, metadata deletion
• Expiration enforcement with clock tamper detection

General Development

• Fastify/Node.js backend APIs
• Next.js admin panels
• SQLite schema design and migration systems
• C++20 client SDKs with CMake
• Lua sandboxing for remote compute environments
• PE parsing and manipulation (Rust or C++)
• Custom encryption schemes and key derivation
• Audit logging and traceability systems

How I Work

• You describe the tool or system you need
• I quote a fixed price and timeline
• I build it. You get source code and build instructions
• You test it. I fix bugs within the agreed scope
• Payment on delivery or milestone-based (negotiable)

Skills & Technologies

Languages

• C++ (C++17/20, Windows APIs, native memory manipulation, PE structures)
• Python (automation, AST manipulation, encryption wrappers, tooling)
• TypeScript / JavaScript (Fastify APIs, Next.js frontend, Node.js tooling)
• Rust (CLI tools, PE parsing, memory-safe systems)
• Lua (sandboxing, embedded scripting, game integration)
• C# / .NET (tooling, IL manipulation, obfuscators, virtualization)

Code Protection & Obfuscation

• IL-level obfuscation for .NET assemblies (control flow flattening, proxy calls, string encryption)
• Code virtualization: converting .NET IL into custom bytecode executed by an embedded interpreter
• Junk code insertion and opaque predicate generation for .NET and native binaries
• Anti-tamper and anti-dump integration for managed and unmanaged executables
• Packing and unpacking techniques for PE files

Reverse Engineering & Deobfuscation

• Dynamic analysis and tracing of .NET assemblies (dnSpy, x64dbg, WinDbg)
• Tracing-based deobfuscation for Python (pdb, pyinstxtractor, runtime hooking)
• Native tracing and debugging for C++ binaries (x64dbg, IDA Pro, Binary Ninja)
• VM-based tracing: recording execution traces of virtualized code to reconstruct original logic
• Static analysis of obfuscated IL, native code, and bytecode (no static devirtualization — tracing only)
• Unpacking and reconstruction of packed binaries from memory dumps

Windows Internals

• PE32/PE32+ file format parsing, modification, and memory mapping
• Manual map loaders (usermode and kernel-mode concepts)
• Anti-debug techniques and debugger detection
• Memory protection and virtual memory manipulation
• Import Address Table (IAT) walking and resolution
• Thread local storage (TLS) callbacks
• Exception handling and unwind information
• HWID spoofing concepts: disk serial, MAC address, volume ID, registry-based identifiers

Security & Cryptography

• AES-256-GCM encryption and decryption
• HMAC-SHA256 for integrity verification
• Argon2 password hashing
• Per-build key derivation and nonce management
• Code cave watermarking and leak tracing
• Signature validation and binary integrity checks

Web & Backend

• Fastify 4 API design with middleware and route architecture
• SQLite schema design, migrations, and WAL mode optimization
• JWT session management and bearer token validation
• Rate limiting, request logging, and audit trail systems
• Next.js 16 frontend with server-side and client-side rendering

Build & Distribution

• CMake project configuration for C++ SDKs
• Cross-compilation and static linking
• PyInstaller hook integration and custom bootstraps
• CI/CD pipeline integration for automated builds

Free Consultation

If you have a project in mind but are not sure what is technically feasible or what it should cost, DM me with a brief description. I will tell you honestly whether I can build it, how long it would take, and what it would cost. No charge for the first conversation.

Terms

• All custom work is source-delivered unless otherwise agreed
• Payment methods: Any cryptocurrency or crypto gift-card
• No refunds once source is delivered
• No chargebacks. Disputes resolved through direct communication
• Support terms agreed per-project (typically 30 days bug fixes)
