Areas of focus

Area Focus
Reverse engineering Binary loading, disassembly, decompilation, and semantic recovery
Decompiler systems IR design, P-Code/NIR/HIR-style pipelines, structuring, and rendering
Security automation Static and dynamic analysis, malware triage, vulnerability research, and forensics
AI-native tooling MCP servers, agent workflows, and source-grounded technical interfaces
Systems engineering Rust workspaces, architecture boundaries, CI, and quality gates
binary → loader → decoder → IR → analysis → structure → readable output → report

Featured systems

Project Role
Fission Primary project — Rust-native decompiler and reverse-engineering workspace
fission-benchmark Reproducible benchmark and evaluation infrastructure for Fission
Reversecore MCP MCP interface for AI-assisted reverse-engineering and security workflows
fossil-mcp Source-grounded implementation search across open-source repositories for AI coding agents

Experimental systems

Project Focus
Eon Typed Rust platform for deterministic calculation and comparison across traditional astrology and divination systems

Stack map

Core:        Rust · Python · Linux · GitHub Actions
Reverse:     loaders · disassemblers · decompilers · IR · P-Code · structuring
Security:    malware triage · SAST · vulnerability research · forensics · reporting
AI tooling:  MCP · agent workflows · source-grounded analysis interfaces

Current direction

I am pushing deeper into decompiler correctness, binary semantics, reproducible evaluation, and AI-assisted reverse-engineering workflows without sacrificing evidence, control, or technical rigor.
