PROFILE SUMMARY

Technology professional with 7+ years delivering enterprise solutions across banking, government, defense, and energy sectors. I design and build systems that solve real operational problems—from military asset management to nationwide access control systems.

Currently building Neumann, a 395K-line Rust distributed database with semantic consensus—developed in 37 days by orchestrating multiple AI coding agents under strict quality gates. This demonstrates both systems architecture depth and practical AI-augmented development at scale.

Strong track record in ITSM platforms (ServiceNow, Cherwell, Ivanti, Jira), cloud migrations, and security implementations. Calm communicator who delivers in both small agile teams and large multi-vendor programmes.

HIGHLIGHT PROJECT

NEUMANN
Dec 2025 - Present
github.com/Shadylukin/neumann
Unified Tensor-Native Distributed Database
395K lines Rust
22 crates
33K+ tests
93% coverage
37 days

A production-grade distributed database runtime unifying relational, graph, and vector storage with semantic consensus. Built using AI-augmented development: architecting modular systems, directing 4-5 coding agents in parallel, integrating under strict quality gates (clippy pedantic, 95%+ coverage targets, 108 fuzz targets).

Distributed Consensus (tensor_chain - 65K lines)
  • Tensor-Raft: modified Raft with geometric optimization—blocks with >95% cosine similarity bypass full validation (40-60% latency reduction)
  • 2-Phase Commit coordinator with DFS-based deadlock detection
  • 6-way semantic conflict classification enabling automatic merge of safe concurrent edits
  • Delta-compressed replication achieving 4-6x bandwidth savings using Tensor Train decomposition
  • SWIM-based gossip protocol with LWW-CRDT semantics for cluster membership
Storage & Query Engines
  • HNSW approximate nearest neighbor with 15 distance metrics; sparse vectors, delta encoding, product quantization
  • Tiered hot/cold storage with automatic migration; Voronoi and k-means semantic partitioning
  • Relational engine with SIMD-accelerated filtering, B-tree/hash indexing, MVCC transactions
  • Graph engine: BFS/DFS, shortest path, PageRank, betweenness centrality, A-star
  • Hand-written recursive descent parser supporting SQL, Cypher-like, unified syntax
Security & Performance
  • AES-256-GCM encrypted vault with Argon2id key derivation and graph-based access control
  • Three-layer LLM response cache (exact + semantic + embedding) with tiktoken token counting
  • Performance: 3.2M PUT/sec | 5M GET/sec | 7.5M concurrent writes/sec @ 8 threads
