Multi-threaded Deep Packet Inspection & Malware Detection Engine

• 438K pkt/s via lock-free pipeline (FNV-1a sharding), zero mutex contention on the hot path
• Byte-level TLS SNI / HTTP Host / DNS parsing via std::string_view, zero heap allocs
• Shannon entropy + Welford variance anomaly in O(1) memory; Random Forest 97% precision
• 1.7× speedup over baseline; classifies 15+ app types from live traffic

Distributed Opportunity Aggregator & ML Recommendation Engine

• Fault-tolerant Playwright ETL across 5 platforms, 5K+ opps/week; composite-key hashing cuts writes ~95%
• Atlas Vector Search (HNSW): O(N) → O(log N), ~10× speedup; sentence-transformers dedup
• Hybrid recommender — TF-IDF + Collaborative Filtering + Vector Search in a FastAPI microservice
• Redis cache: p95 inference 400ms → <80ms (80% reduction)

C-Subset Recursive-Descent Compiler

• Hand-written recursive-descent parser → AST → semantic analysis (type checking, scope resolution)
• 3-address IR (TAC) with basic-block CFG — constant folding, DCE, copy propagation → ~25% fewer instructions
• 100+ pytest cases: pointer arithmetic, nested scopes, register spilling
• Symbol-table-driven linker helper across translation units
