Undergraduate Computer Science student at Universitas Sebelas Maret (UNS), focusing on systems programming, binary analysis, process memory forensics, and 3D asset engineering.

Active learner, driven by curiosity about how software works beneath the surface: from decompiling proprietary game archives and tracking runtime heap memory structures, to building standalone glTF 3D pipelines and interactive open-data tools. Always open to code reviews, constructive feedback, and collaborative projects.

Stack: Python 3.10+ • NumPy • UnityPy • CTypes • SQLiteMC • glTF 2.0

An offline reverse engineering suite and modular glTF 2.0 3D asset extraction pipeline targeting game client archives:

• AES-256 SQLite Database Decryption: Uses raw Windows C-runtime bindings (sqlite3mc_x64.dll) to decrypt PBKDF2 HMAC-SHA1 secured database manifests.
• Vectorized Rolling XOR Engine: Decrypts encrypted Unity bundles with an 88-byte keystream cycle, accelerated 73.8x using NumPy vectorization.
• Standalone glTF 2.0 Binary Compiler: Custom-built .glb compiler that serializes binary buffer views, accessors, materials, and skeletal hierarchies without third-party 3D engines.
• Anatomical Assembly & Alpha Blending: Automatically calculates skeletal attachment matrices ($Y = 0.4963\text{ m}$ neck, $Y = 0.3053\text{ m}$ tail) and assigns transparent alpha blending (alphaMode: BLEND) to facial expression submeshes.

Stack: Python 3.10+ • Win32 API (ReadProcessMemory / WriteProcessMemory) • Zstandard • CustomTkinter

A live Windows process memory editor and save-game database parser for Football Manager 26:

• Direct Process Memory Manipulation: Resolves multi-level dynamic pointer chains to read and patch live player attribute structures (ACTUAL_PLAYER@db) at runtime.
• Save Stream Decompression: Zstandard stream decompression engine indexing 46,500+ players and 988,000+ name dictionary entries in under 0.15 seconds.
• Attribute Scale Translation: Automatically converts front-end display ratings (1-20) to internal binary values (5-100 at offset +0x15F).
• Tactical Telemetry GUI: Modern desktop interface with one-click attribute preset boosting and live memory validation.

Stack: Vanilla JavaScript • Open Data Architecture • GitHub Pages

An interactive admissions analytics platform and risk calibration simulator covering 50 premier Indonesian universities (35 PTN & 15 PTS):

• National Selectivity Leaderboard: Real-time quota allocations, historical applicant volumes, and 3-year competitiveness trajectories.
• Choice Risk Simulator: Dual-track heuristic algorithm evaluating admission risk across SNBP and SNBT examination tracks.
• Zero Heavy Dependencies: Lightweight client-side engine with instantaneous search and bilingual localization (ID / EN).
