Deep Technical Archive
This section is for readers who already know they want the hard proof.
It collects the work that sits below the homepage sales layer: embedded cryptography, protocol analysis, deterministic runtime design, constrained-memory engineering, and boundary-level debugging.
What you will find here
- SM9 and pairing-heavy cryptography under extreme memory constraints
- Protocol reverse engineering and firmware boundary analysis
- Deterministic runtime design and hardware-software co-design
- Legacy migration and security hardening for fragile production systems
- Deep system recovery work where observability, precision, and execution discipline matter
Selected Deep Dives
Engineering Cryptographic Systems in 13KB RAM
- Hand-rolling SM9 (IBC) Cryptography for 8KB RAM Environments
- System Sovereignty Under 12KB Constraints
- Technical Whitepaper: Deterministic Computing
This cluster covers pairing optimization, stack discipline, deterministic memory layout, and the realities of cryptographic implementation under severe embedded constraints.
Protocol and Boundary Analysis
- Cross-Language Bridge Engineering
- USB HID Protocol Boundary Fixes
- Legacy 3DES Hardening
- Web3 Scam Exposure
This cluster shows how I work across protocol internals, firmware boundaries, host-device mismatches, and security-sensitive integration points.
Systems Under Operational Pressure
- Frontend Stabilization Under Production Pressure
- Stabilizing and Modernizing a Legacy Industrial SCADA Platform (Qt 4.7 / VS2003)
- Technical Debt Governance: Dismantling the “Microservice Tax”
- Reliability Audit: Toyoko INN Reservation System
- ETL Optimization
This cluster demonstrates the same engineering discipline in backend, reliability, and modernization work.
