Designing an AI Resume-Parsing Pipeline with Node.js, PostgreSQL, and OpenAI

Описание и применение

Talynce создала пайплайн для парсинга резюме, использующий Node.js, PostgreSQL, Redis и OpenAI, превращая PDF/DOCX в структурированные профили кандидатов, пригодные для ATS и AI‑отборов.

Задача

Hiring teams drown in PDFs. A useful AI resume parser does more than OCR: it turns messy documents into structured candidate profiles your ATS can rank, search, and interview against.

Результат

Talynce achieved a reliable, idempotent resume parsing pipeline that outputs structured profiles, enabling efficient ATS operations and AI-driven screening.

Рабочий процесс

• Ingest candidate upload or ATS import into object storage; a Redis-backed job queue picks it up.
• Extract text from PDF/DOCX to plain text (and lightly structured blocks).
• LLM extract using OpenAI with a strict JSON schema; retry on schema validation failure.
• Validate & merge with rule checks (dates, email format) and confidence scores; humans can override in UI.
• Index the profile for AI screening, phone interviews, and video interviews downstream.

At Talynce, we built our parsing stack on Node.js, PostgreSQL, Redis, and OpenAI (plus Gemini where it helps). No Python in the hot path — the same language as our Next.js app and API.

A resume is not one blob of text. We normalize into fields recruiters actually filter on: Identity, Work history, Education and certifications, Skills with evidence spans from the source text, Links.

Everything lands in PostgreSQL with JSONB for variable sections and typed columns for the filters that must stay fast.

Pipeline shape: 1. Ingest… 2. Extract text… 3. LLM extract… 4. Validate & merge… 5. Index…

Schema first. Define the JSON schema before prompt tuning. Reject incomplete objects instead of silently storing junk.
