HireSense Resume Parser LoRA is a fine-tuned adapter model built on top of Qwen3-4B-Instruct using QLoRA and supervised fine-tuning (SFT). The model is designed to extract structured JSON information from resumes for downstream recruitment and candidate-job matching workflows.

The model converts raw resume text into a consistent structured schema containing:

Personal information
Skills
Education
Work experience
Projects
Certifications

This model is intended to be used as a component in AI-powered hiring pipelines and resume analysis systems.

Developed by: Rohit BK
Model type: Causal Language Model (LoRA Adapter)
Language(s): English
License: Apache-2.0
Finetuned from model: unsloth/qwen3-4b-instruct-2507-unsloth-bnb-4bit

Model Sources

Base Model: Qwen3-4B-Instruct
Frameworks: Transformers, PEFT, TRL, Unsloth

Uses

Direct Use

This model is intended for:

Resume parsing
Structured information extraction
Candidate profile generation
Resume-to-JSON conversion
Recruitment automation systems

Example output schema:

json

{
  "name": "John Doe",
  "email": "john@example.com",
  "phone": "9876543210",
  "skills": ["Python", "React", "SQL"],
  "education": [
    {
      "degree": "B.Tech",
      "institution": "XYZ University",
      "year": "2025"
    }
  ]
}

Downstream Use

The model can be integrated into:

Applicant Tracking Systems (ATS)
Resume ranking systems
Semantic candidate matching pipelines
Recruitment copilots
Hiring analytics dashboards

Out-of-Scope Use

This model is NOT intended for:

Final hiring decisions
Automated candidate rejection without human review
Personality assessment
Predicting candidate success
Sensitive demographic inference

Human oversight is strongly recommended.

Bias, Risks, and Limitations

The model may:

Produce incorrect or incomplete JSON
Miss information in poorly formatted resumes
Exhibit biases inherited from training data
Struggle with multilingual resumes
Perform inconsistently on highly creative resume layouts

The model should not be used as the sole decision-maker in hiring processes.

Recommendations

Users should:

Validate generated outputs before use
Use human review for hiring decisions
Combine the model with rule-based validation systems
Avoid relying solely on generated scores or rankings

How to Get Started with the Model

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

base_model_id = "Qwen/Qwen3-4B-Instruct"
adapter_id = "YOUR_USERNAME/HireSense-ResumeParser-LoRA"

tokenizer = AutoTokenizer.from_pretrained(base_model_id)

base_model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    device_map="auto"
)

model = PeftModel.from_pretrained(base_model, adapter_id)

prompt = """
Extract structured JSON information from the following resume.

Resume:
John Doe
Python Developer
Skills: Python, React, SQL
"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=256
)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training Details

Training Data

The model was trained on structured resume-to-JSON instruction pairs containing:

Resume text
Extraction prompts
Structured JSON outputs

Training data included synthetic and manually curated resume samples.

Training Procedure

The model was fine-tuned using:

QLoRA
Supervised Fine-Tuning (SFT)
4-bit quantization
PEFT adapters

Training Hyperparameters

Training regime: bf16 mixed precision
Fine-tuning method: QLoRA
Quantization: 4-bit NF4
Optimizer: AdamW
Frameworks: Transformers + TRL + Unsloth

Evaluation

Metrics

The model was evaluated qualitatively on:

JSON validity
Field extraction accuracy
Structural consistency
Hallucination frequency

Results

The model demonstrated:

Consistent JSON generation
Good extraction performance on structured resumes
Improved formatting consistency compared to the base model

Performance may degrade on:

Image-based resumes
Multi-column layouts
Highly unstructured resumes

Environmental Impact

Hardware Type: NVIDIA GPU
Training Framework: Unsloth
Quantization: 4-bit QLoRA

Technical Specifications

Model Architecture and Objective

This model uses:

Qwen3-4B-Instruct as the base model
LoRA adapters for parameter-efficient fine-tuning
Causal language modeling objective
