PacketSentinel

Multi-threaded Deep Packet Inspection & Malware Detection Engine

• 438,000 pkt/s via lock-free pipeline (FNV-1a flow-table sharding) — zero mutex contention on hot path
• Byte-level TLS SNI, HTTP Host, DNS parsing via std::string_view — zero heap allocations on hot path
• Shannon entropy + Welford variance anomaly in O(1) memory; Random Forest 97% precision on DDoS/C2 datasets
• 1.7× speedup over single-threaded baseline; classifies 15+ application types from live traffic

Relay

Adaptive RAG-Powered AI Collaborative Developer Ecosystem

• Custom RAG pipeline — 768-dim Gemini embeddings + Atlas Vector Search, sub-50ms semantic retrieval across 10,000+ docs (60× over regex)
• RelaySandbox — real-time collaborative editor (Socket.IO, 13 events), 11 compiled languages, dual-compiler failover, 50+ concurrent rooms
• Redis sliding-window rate limiter (AI: 10 req/min; Compiler: 15 req/min) with dual Gemini model failover
• 40+ REST endpoints, Dockerized CI/CD, MongoDB TTL auto-purge on activity logs

OppLens

Distributed Opportunity Aggregator & ML Recommendation Engine

• Fault-tolerant Playwright ETL scraping 5 platforms — 5,000+ opportunities/week; composite-key hashing cuts redundant writes by ~95%
• Atlas Vector Search (HNSW) replacing O(N) → O(log N), ~10× speedup; sentence-transformers semantic dedup
• Hybrid NLP recommender — TF-IDF + Collaborative Filtering + Vector Search in decoupled FastAPI microservice
• Redis cache cuts p95 ML inference from 400ms → <80ms (80% reduction) on high-frequency queries

AstraC Compiler

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, dead-code elimination, copy propagation → ~25% instruction reduction
• 100+ pytest cases covering pointer arithmetic, nested scopes, register spilling
• Symbol-table-driven linker helper across translation units — mirrors PTXAS front-end responsibilities
