HQLS, a specialized financial translation agency with 20 years of expertise, faced existential threats from AI-powered translation services disrupting the industry. Traditional human translation was becoming cost-prohibitive for clients, yet pure AI translations lacked the financial domain expertise and accuracy clients required. The agency needed a proprietary platform that combined AI efficiency with human expertise to remain competitive while scaling operations without proportionally increasing costs.
We designed a hybrid AI-human translation workflow platform that leverages multiple AI translation engines (DeepL, Google Translate, OpenAI) with specialized financial terminology databases. The system pre-translates documents using AI, then routes them through quality assurance workflows where human experts review and refine AI translations. We implemented a smart routing algorithm that assigns translation complexity scores and automatically determines which documents need human review versus AI-only processing. The platform includes a custom financial glossary management system, client portal for document uploads and tracking, and automated quality scoring based on financial accuracy metrics.
Built a full-stack translation management platform with React/TypeScript frontend hosted on Vercel and Node.js backend on Heroku. MongoDB stores client data, project histories, and custom financial terminology dictionaries. Integrated multiple AI translation APIs with fallback logic and quality comparison. Cloudinary handles secure document storage and processing. The platform features: multi-engine AI translation with quality scoring, custom financial glossary editor with 15,000+ specialized terms, intelligent human review routing based on document complexity, client portal with real-time translation status tracking, automated quality assurance scoring system, cost calculator showing hybrid vs. traditional pricing, and admin dashboard for workflow management and translator assignment.
