I am an AI engineer and NLP specialist with hands-on experience building language model pipelines, computer vision systems, and machine learning solutions. I have trained RoBERTa models for Persian sentiment analysis, developed semantic tokenization methods, and worked with large-scale Persian text datasets across multi-node and multi-GPU environments. My background also includes license plate detection, OCR, image generation, and model fine-tuning using Python and modern machine learning frameworks. I enjoy solving challenging engineering problems and turning research ideas into reliable, practical systems. As a collaborative team lead, I share my knowledge with colleagues and bring a positive, committed approach to every project. I am especially interested in generative AI, large language models, computer vision, distributed training, and improving the efficiency of data movement and access for GPUs.

Work Experience

Team Lead & NLP Specialist at ParsTech.Co
January 1, 2023 - Present
Built training and inference pipelines for masked language models used in sentiment analysis. Trained a RoBERTa model across two nodes with multiple GPUs using 1.2 TB of collected Persian text. Implemented a Persian semantic tokenizer that reduced vocabulary size by up to 80% compared with BPE tokenization and improved MLM model accuracy by 20%. Educated four coworkers in NLP skills.
ML Engineer & Python Developer at ParsTech.Co
January 1, 2022 - January 1, 2023
Trained YOLOv5 from scratch on a collected Iranian license plate dataset covering different weather conditions, achieving 98% accuracy. Designed a generator for license plates with varied realistic effects. Generated Persian text images using custom fonts and backgrounds to fine-tune EasyOCR for Iranian identity cards, achieving 99% accuracy.
