Harmful Algal Bloom RL Simulation (AlgeaMind)
2026A reinforcement-learning simulation of algal bloom remediation, pitting three agents — heuristic, RL and Claude API — against a grid modelling 5+ per-cell environmental variables, with intervention costs benchmarked against real-world remediation records. A React/TypeScript frontend visualises agent behaviour and environmental state in real time over a Python FastAPI backend.

Reliable Data Transfer Protocol over UDP
2026A reliable data-transfer protocol written from scratch in Java over raw UDP, covering packet serialization, alternating-bit sequencing and timeout-driven retransmission. Stress-tested under four adversarial network conditions — 100ms and 1100ms delays, 50% client and server packet loss — using Linux network namespaces and tc netem fault injection, with every test scenario transferring successfully.

Concordia Thesis Scraping and Clustering
2025A five-stage information-retrieval pipeline — crawler, PDF extractor, tokenizer, TF-IDF, K-Means — run over Concordia's Spectrum thesis repository, with retry logic and robots.txt compliance for production-grade crawling. A 5,000-feature TF-IDF vocabulary clustered at k = 2, 10 and 20 surfaces groupings from broad disciplines down to niche subfields like robotics and patent law.

Reuters SPIMI Indexer and Search Engine
2025Three search-indexing architectures — naïve, SPIMI and compressed — built and benchmarked over 21,578 Reuters documents, reaching sub-millisecond query latency with configurable tokenization. The comparison demonstrates SPIMI's scalability advantage over naïve in-memory indexing at scale, with lossy compression shrinking the index while preserving query performance.

BookNotes Web Application
2025A full-stack reading tracker with authentication, CRUD and Open Library API integration, using an LRU cache to cut redundant external API calls. Hardened with ISBN-10/13 checksum validation and parameterized SQL to eliminate injection risk, plus debounced lookups and dynamic SVG cover previews.
