Prove that migrated, converted or rewritten SQL returns the same result as the original: statements mapped one to one, two-way key diffs, and checkers shown to catch seeded differences.

bagit-completeness-fixity-auditSeparate BagIt structural completeness from checksum validity using bag inventory, manifests, fetch entries and full digest evidence. Use when fast validation passed, a transferred bag needs fixity review or missing payloads must be distinguished from changed bytes. Not for repairing, downloading or
dbt-model-refactor-and-docsSplit a large warehouse or dbt model into staging and intermediate models without changing its output, explain a model's upstream and downstream path from compiled SQL and lineage, and bring model and column descriptions in line with the real selected columns. Use when someone wants to decompose a l
multi-file-lab-workbook-harmonizationMerge many lab or instrument workbooks of similar but not identical layout into one table - inventory every file and sheet (header row, columns, units, date format), group files by layout variant, write a target schema with a per-variant column mapping, convert units and dates by explicit rules, rec
ocr-pdf-text-image-alignment-checkCompare a saved searchable PDF's text positions with its visible scans and approved page anchors. Use when OCR words look plausible but highlights shift, rotate or omit pages, or a sidecar is offered as proof. Not for PDF reading-order audits or redaction.
semi-structured-field-extractionTurn log lines, bench or test data and JSON documents into typed columns and a plot-ready table - inspect real samples and list every field, unit and type variation, map each source field to a column with an explicit cast and a policy for missing, string, array and wrong-type values, verify row coun
sql-migration-equivalence-checkProve that a migrated, dialect-converted, optimized or extended SQL query or table returns the same result as the original - number the statements in source and converted script, write row-count, two-way key anti-join and null-safe per-column diff queries, seed deliberate differences to show the che
Your own Naver blog, Place, Smart Store, shopping, search ad and news comment data read through the datalab.tools browser extension, plus card news, short-form video, tutorial posts and social copy built in its editors, with no invented numbers and no change made without asking.
31 skills
Numbers that mean what they say: ClickHouse SQL that reads the key and deduplicates correctly, Naver trend data read as ratios, metrics defined once, experiments designed before launch, retention read by cohort, and open survey responses grouped with every response id kept.
16 skills
Reading passages that hit a measured grade level, language drills, and teacher-side checks for coverage, answer keys, lesson timing, study calendars and rule-valid puzzles, with the numbers and logs shown.
14 skills
Growth and community work: store listings written for the people searching that store, Discord servers run with structure and consistent moderation, newsletters readers open and finish, a month of social posts a small team can ship, launch emails that lead with what changed, and sites submitted to Google, Naver and IndexNow engines from a pipeline.
13 skills
Early product-planning steps done carefully: spar on an idea, frame the problem behind a request, synthesize feedback without overstating it, rank a backlog while saying where the ranking is fragile, write a Korean PRD with testable acceptance criteria, and put a decision on one page with the recommendation first.
13 skills
Korean content that reads well and stays true: product copy fixed to the Toss writing principles, Naver blog posts planned for search, persona tone measured with markers, and ghostwriting that never invents the author's facts.
