Senior Backend Architect / Principal Engineer
I provide maximum engineering ROI by solving complex, mission-critical architectural bottlenecks without taking on administrative people-management roles. Operating at the convergence of cryptographic security, distributed systems, and bare-metal performance.
The Three Pillars of Infrastructure
Pillar 1: Cryptographic Security
- Hand-Rolled Cryptographic Primitives: Implemented ECC, SM2/SM3/SM4/SM9 from scratch under <8KB RAM.
- Threshold Secret Sharing: (5,3) Shamir Threshold schemes and KDF-based key diversification.
- Side-Channel Resistance: Constant-time execution paths for timing attack prevention.
Pillar 2: High-Performance Infrastructure
- Deterministic Computing: VM execution optimization and bytecode-level performance tuning.
- Kernel Surgery: Linux kernel tuning (eBPF, Cgroups) and sub-microsecond IPC (200ns).
- Storage Engineering: Hyper-scale cluster optimization for 10.7 billion records.
Pillar 3: Distributed Systems & Concurrency
- Resilient Control Planes: Architected Go+Neo4j routing engines with 90% bandwidth reduction.
- Rescue Engineering: Stabilized paralyzed platforms and eradicated “distributed monolith” crises.
Technical Lexicon
- Expertise: C/C++, Go, Assembly, Linux Kernel, eBPF, Cryptography (SM-series).
- Infrastructure: Docker, Kubernetes, CI/CD Hardening, Zero-Copy IPC.
- AI Tooling: Autonomous Codebase Auditing (Claude Code / DeepSeek).
Engineering Highlights
- 50x Throughput Boost: Re-engineered synchronous pipelines into async batch-upsert architectures (70s → 1.5s).
- 92% Memory Reduction: Optimized crypto engines for extreme embedded constraints (120KB → 9.3KB).
- Rescue Mission: Restored paralyzed grid operations in zero-documentation environments.
