Large-Scale Project
Thai Subtitle Translation & QC Platform
A B2B SaaS platform that manages the end-to-end workflow for Thai subtitle translation of video content. From video series/episode management to automatic translator assignment, AI quality checks, and invoice generation—all in one system.
Auto-Assignment Engine for Translators & Reviewers
A system that automatically selects the optimal translator and sends offers triggered by episode publication.
- Scoring algorithm: Track record (60%) + availability (40%) + series affinity bonus (up to +20 pts) for 3-axis candidate ranking
- 2-stage offer system: Stage 1 sends individual offer to top scorer → Stage 2 sends batch offer to remaining candidates (first-come-first-served) on decline/expiry
- Auto cascade: Translator acceptance → triggers reviewer auto-assignment (prevents same-person dual roles)
- Cron-based offer expiry management: Detects expired offers every 15 min and auto-re-offers to next candidates
- Notification integration: In-app + email (Postmark) + Slack for real-time 3-channel notifications
AI Quality Check (QC) System
Automated subtitle quality inspection powered by LLMs.
- Thai character counting: Accurate count excluding tonal marks & vowel diacritics (max 39 chars per line)
- Multi-stage QC: Preflight (post-upload) and Postflight (pre-delivery) two-stage checks
- Auto-fix suggestions: Safe automatic corrections for punctuation, whitespace, and terminology
- Glossary integration: Automatic consistency check with series-specific glossaries
- Auto status transition: Automatically moves to 'passed' when zero errors detected
Subtitle Editing & Management
Multi-format subtitle editing system with collaboration features.
- Bidirectional VTT / SRT format conversion & parsing
- Per-cue (dialogue) editing & history management
