Competitive-programming stats with head-to-head leaderboards. JWT auth with Google OAuth, bcrypt hashing and token-based password reset over a normalised Postgres schema; a rate-limited Codeforces client with Postgres-backed caching aggregates acceptance rate, problems solved and rating history. Auth routes get stricter per-IP limits than the rest of the API.

Watches this machine's listening TCP/UDP sockets and flags anything that drifts from an approved baseline — a new port, a baselined port whose owning process or user changed, or a service that quietly stopped listening. Reads /proc/net/{tcp,udp} directly and resolves socket inodes to PIDs through /proc/[pid]/fd, so it has no runtime dependencies at all.

Redacts personal data out of .docx files by unzipping the OOXML, parsing word/document.xml, replacing values with deterministic fakes and repacking the archive. Hybrid detection — regex, a gazetteer and an address detector — chosen over NER and argued for in the README, with an eval command that scores its own precision, recall and F1 against ground truth.

The same Codeforces aggregation as the dashboard, without the browser. Looks up and compares profiles — rating, rank, problems solved, acceptance rate and a rating-wise problem histogram — straight in the terminal.

A screenshot and screen-recording chooser for Hyprland and other wlroots compositors — the GNOME capture flow on Wayland, without GNOME. The screen is live the moment it opens, so you can drag a region before deciding anything; the toolbar stays clickable over the live screen, recordings keep an elapsed timer, and it remembers your last choice so the common case is press-key, press-Enter.

A configurable parser that turns workflow event payloads into normalised Postgres rows from a spreadsheet-defined mapping — adding a service is a row in a sheet, not a code change. Repository abstractions over pgx, JSONB for the parts that stay unstructured, Tern migrations, Docker Compose for the whole thing. The pattern behind my work at NIC.

Copies a master resume inside Google Drive, appends the company name to the filename, sets link-view sharing and prints the link — one command per application instead of six clicks. OAuth desktop flow, token cached locally, credentials never committed.
