The Problem
Recruitment teams are often overwhelmed by hundreds of resumes for a single job opening. Manual screening is not only time-consuming (averaging 23+ hours per hire) but also prone to unconscious human bias and inconsistent evaluation. Key candidate data is locked in unstructured formats (PDF/DOCX), making objective comparisons against specific job requirements extremely difficult and error-prone.
Our Solution
RecruitAI is an AI-driven platform that automates the initial recruitment funnel. It allows recruiters to upload batches of resumes and compare them instantly against a Job Description (JD). The solution uses advanced LLMs to:
- Extract structured data (names, contact info, skills, education) from diverse document types.
- Quantify Candidate Fit using a weighted scoring algorithm for skills, experience, and education.
- Generate High-Level Summaries, strengths, and gap analysis for every candidate, moving beyond simple keyword matching to contextual understanding.
Solution Architecture
The system follows a modern, serverless-ready architecture:
- Client Interface: A high-performance Next.js frontend with a premium, responsive UI for seamless document uploads and result visualization.
- AI Orchestration Layer: A robust API backend that manages the flow of data between file parsers and the Gemini AI engine.
- Processing Pipeline: Specialized utilities (mammoth and unpdf) extract raw text, which is then analyzed by Generative AI via JSON-schema-enforced prompts.
- Data Persistence: A MongoDB database stores every “Screening Run,” preserving history and allowing for later retrieval of candidate rankings.
- Security Layer: Secure authentication using JWT and HttpOnly cookies to protect sensitive candidate information.
Deliverables
- Interactive Screening Dashboard: A “Start to Finish” workstation for uploading JDs and resumes.
- Automated Ranking Engine: A real-time scoring system that sorts candidates by “Strong Fit,” “Consider,” or “No Fit.”
- Insightful Candidate Cards: Deep-dive summaries including matched skills, experience highlights, and critical gaps.
- Historical Analytics: A centralized repository of past screening sessions for collaborative hiring.
Tech Stack
| Layer | Technology |

Business Impact
- Drastic Efficiency Gains: Reduces initial screening time by up to 80%, allowing HR teams to focus on interviewing rather than parsing.
- Improved Quality of Hire: Semantic AI matching identifies “hidden gems” that traditional keyword filters might miss.
- Standardized Evaluation: Ensures every candidate is judged against the exact same criteria, significantly reducing subjective bias.
- Scalability: Enables small recruitment teams to handle enterprise-level applicant volumes without increasing headcount.
