Software Developer | Reverse Engineer | Local-First AI Architect

I build native Nintendo Switch homebrew, zero-dependency save editors, and offline AI systems. My doctrine is simple: byte-verified or it doesn't ship. I maintain a public corrections log, prioritize safety-first engineering, and let the code speak for itself.

• 1,800+ downloads served across all open-source projects.
• #1 Post of All Time on r/SwitchPirates: Atmosphere 1.12.1 announcement (39K+ views, 159 upvotes, 99% upvote ratio, 63+ comments).
• #2 Post of All Time on r/SwitchPirates: FW 23.0.0 Recovery Guide (26.9k views, 82 shares, 46 comments, 91% upvote ratio) - maintained with a public corrections log and maintainer-verified fixes (bth, hexkyz).
• Zero lost saves across 1,000+ installs of ACNH-Save-Editor, thanks to a byte-verified backup + dual-file commit safety pipeline.
• Global Reach: Top viewers from United States (42.4%), Canada (8.6%), Germany (11.5%), Brazil (4.3%), and UK (5.5%).

AI & Tools:

A 100% native Switch save editor for Pokémon Scarlet & Violet. No PC, no save dumping, no bridges. v0.9.5 QoL sprint live.

• RE Highlights: Cracked Gen 9 SCBlock/SCXorShift32 save structure with SHA256 footer verification. Ported PKHeX SpeciesConverter to fix Paldean ID divergence. Built a legality-aware generator with real learnsets and growth-correct EXP curves.

The first 100% native Switch save editor for Animal Crossing: New Horizons. v1.4.0 live (1,536+ downloads). v1.5.0 Room Decorations Injector in dev.

• RE Highlights: Cracked AES-encrypted economy integers split across personal.dat and main.dat. Implemented automatic Murmur3 hash healing. Mapped the pocket item table (8-byte slot records at 0x2A00) powered by a 13,000+ item database.

The first native Switch save editor for Digimon Story: Time Stranger.

• RE Highlights: Achieved direct NAND FS access (no bridge required). Located Yen value at offset 0x7973 (u32 LE). Discovered the fsFsCommit() requirement to prevent silent NAND rollbacks.

Fallout-themed Pokémon ROM hack led by abelardthebard. Contributing creature design, BST/stat balancing, lore-to-mechanics ability mapping, and type-chart optimization. Currently locking in the early-game batch (Dogmeat starter branches, Mutant Hound lines).

• r/SwitchPirates 23.0.0 Recovery Guide: Authored the definitive troubleshooting guide. Maintained with a public corrections log and maintainer-verified fixes (bth, hexkyz).
• OpenNOW-Switch: Conducted deep hardware QA. Isolated a DTLS stream negotiation hang, caught a critical global input regression that CI missed, and held the QA block on the native-Switch implementation to document a lifecycle crash before merge.
• flamoris-ai-agent: Executed full local acceptance checklist. Identified critical friction points (UTF-8 encoding traps, API mismatches) which directly influenced the maintainer's architectural refactor (PR #20).
• GitProfileLens: Implemented keyboard-accessible copy feedback with aria-live announcements and rewrote unit tests to exercise real production handlers.
• Dusklight: Diagnosed a version mismatch between .nro NACP metadata and the in-game menu. Proposed three distinct CMake/release pipeline solutions.

Left: Resume Parser + Brutal Interview Simulator | Right: Job Hunt Kanban Tracker

• 🐉 Uncensored Dungeon Master: Persistent world state, combat tracking, lore RAG, session chronicles.

• 💼 Brutal Interview Simulator: Realistic hiring manager persona with scored feedback.

• 🛠️ PC Diagnostic Agent: Executes local PowerShell tools safely via permission gate.

• 🧠 Fully Offline: Runs on Ollama + ChromaDB. Zero data leaves the machine.

Emergent colony governance with elected mayors, task delegation, and persistent creature relationships

• 🧠 Persistent Individual Minds: Unique memory, personality, and relationship maps per agent.

• 🏛️ Elected Governance: Dynamic mayor elections with leadership scores and task assignment.

A zero-dependency, safety-first CLI that maps your second-degree GitHub network to surface high-signal developers. Pure Python stdlib — no pip, no frameworks.

• Smart Quality Gate: Automatically filters out bots, mass-followers (>800 following), and empty accounts (<3 repos) to find true domain experts.
• Real-World Proof: Used this exact tool to discover and connect with Switch homebrew legends (ClusterM, fincs, WinterMute) and local-AI architects.

"Your Phase 0 feedback helped us catch exactly the kind of portability issues we wanted to eliminate."
— akino-nanto, flamoris-ai-agent maintainer (on PR #20)

"I told my niece I corrupted her island... she dubbed you 'Corrupt Bro'. Restoring the Zelda save sounds complicated so I think I'm going to stop but I'm happy the switch is working again. Again, you're an awesome person for taking the time to help me troubleshoot."
— igomhn3, ACNH-Save-Editor User (after a successful NAND rescue)

"Thanks for the heads up on the dvr patches. I don't have any reason to update my emummc right now but when I do update it and my games crash, I'll know why"
— SwellEquis, r/SwitchPirates (preventative harm reduction working in the wild)

I leverage deep expertise in reverse engineering, systems programming, and local AI architecture to solve complex technical challenges. I prioritize safety, transparency, and byte-verified integrity.

• ✍️ Technical Writing: Translating low-level concepts into actionable guides (e.g., the 26.9k+ view r/SwitchPirates recovery guide).
• 🐛 Security Auditing & QA: Finding edge cases CI misses. Focused on memory safety, crypto implementations, and Horizon OS crash-screen decoding.
• 🛠️ Systems Engineering: Building zero-dependency diagnostic agents for secure, offline workflows.
