Decode 64-bit Snowflake-style IDs for Discord, Twitter, Mastodon, Sonyflake, Instagram, or a custom bit profile. Extract timestamp, worker/process/machine, sequence fields, align platform epochs, and infer a Discord shard when a shard count is supplied.

Surgically repair malformed CSV rows one at a time: unescaped (stray) quotes, mixed delimiters (tab/semicolon/comma in the same file), BOM-prefixed headers, CRLF/CR line endings and trailing empty lines. The surgeon parses tolerantly, shows a row-level red/green diff of every change it made (before → after, with the repair reason tagged), lists the rows it accepted unchanged, and emits the cleaned CSV. Optional AI repair can review suspicious rows after the deterministic pass. It complements the CSV Validator (which only reports problems) by actually fixing the damaged rows.

Format and beautify minified or messy CSS code into readable, well-indented stylesheets

Map messy CSV headers onto a clean target schema. Paste a CSV whose first row holds inconsistent column names (Customer ID, user_id, customerId, CUST_ID…) plus your target schema (one column per line) and an optional "alias=target" dictionary. Each source header is resolved through four layered passes — exact, dictionary, normalized (strips case/accents/separators/camelCase), then fuzzy edit-distance — and shown in a mapping table with method and confidence, plus target coverage and an optional normalized CSV export.

Dissect the HTTP/3 over QUIC handshake byte-by-byte. Visualise the 1-RTT fresh handshake, session-ticket resumption, and 0-RTT early-data scenarios, with sequence diagrams, per-packet field layouts, the Retry packet, and a side-by-side comparison against TCP + TLS 1.3. Built for interview prep, protocol learning, and performance engineering.
