AI-Based Resume Parsing for a Job Portal with Skills Matching
Overview
An international HR firm approached us to revolutionize their traditional job portal using Artificial Intelligence. Their primary goal was to automate resume parsing, improve candidate-job matching, and ultimately boost recruiter productivity while reducing time-to-hire.
We delivered an AI-driven resume parser and skill matcher, built on ASP.NET Core, capable of understanding natural language resumes, extracting structured information, and matching candidates to jobs using machine learning-based algorithms.

Key Features Implemented
|
Feature |
Description |
|---|---|
|
AI Resume Parsing |
Extracts structured data like name, email, phone, education, experience, skills from PDFs, DOCX, and images using OCR. |
|
Skill Matching Algorithm |
Uses NLP and vector similarity (BERT embeddings) to match candidates to job descriptions based on skill relevance. |
|
Candidate Scoring System |
Calculates a match percentage (0-100%) and ranks candidates for each job post. |
|
Real-Time Dashboards |
Displays insights like top skills, source channels, average matching score per post. |
|
Feedback Loop Training |
The AI improves accuracy over time using recruiter feedback on match quality. |
|
GDPR & Compliance Ready |
Data anonymization, audit logs, and access control for global compliance. |

✅ Color-coded match scores were added to improve decision-making UX.
Deployment & Integration
- Modular Microservice-based AI layer hosted on Azure
- Integrated into client’s existing ASP.NET Core-based platform
- REST APIs enable future plug-ins with ATS (Applicant Tracking Systems)
- Secured with JWT Auth and Azure Key Vault for secrets management
Results & Business Impact
Tangible Outcomes:
- 87.5% reduction in manual screening time
- 53% increase in monthly hires
- Improved candidate experience with faster responses
- Scalable infrastructure for global hiring
Intangible Benefits:
- Improved recruiter morale
- Reduced hiring bias
- Enhanced employer brand perception
Lessons Learned
- AI parsing must be context-aware (e.g., “Java” as skill vs island).
- Human-in-the-loop feedback improved model precision by 18% over 3 months.
- Recruiter UX is just as critical as algorithm performance.

- Launch candidate self-assessment tool for skill benchmarking
Final Thoughts
This project transformed a legacy HR platform into a smart hiring ecosystem, demonstrating how AI can dramatically enhance hiring productivity, reduce costs, and improve talent outcomes.
✅ “AI-powered hiring isn’t just the future — it’s the new standard.”
