Things I've built.

A secure, lightweight desktop password manager. Credentials are encrypted with AES-128 (Fernet), and the key is derived from your master password via PBKDF2-SHA256.

Crawls quotes.toscrape.com and exports quotes, authors, and tags to CSV. A clean example of the fetch → parse → extract → save workflow, with rate-limiting and error handling.

A desktop finance app with a dashboard, transaction tracking, recurring subscription management, and savings goals with progress bars — stored locally in SQLite.

A CSV → Parquet → BigQuery pipeline built around a real ~54k-row open dataset, converted to partitioned Parquet and loaded with an explicit schema and idempotent re-runs.

A personal test in developing and using a firewall built in Python, layered on top of iptables/nftables rules for real traffic filtering.
