À propos de Aymen

Hello, I am Aymen, I'm an AI engineer with strong expertise in Language Modeling and ASR systems (Automatic speech recognition)
I have been working in the NLP and ASR fields since 2020 and here are my main skills:

-Fine-tuning ASR models ( Conformer and Whisper)
-Training and deploying large-scale deep learning models
-Implementing tokenization strategies
-Developing efficient web scraping solutions
-Prompt engineering for LLMs
-Integrating n-gram language models with ASR systems
-Large-scale data processing for training and inference
-Specializing in multilingual ASR/LMs development for Arabic, French, and English, leveraging my fluency and expertise in the linguistic nuances of these languages.-Optimized handling of millions of audio files for ASR tasks

For well-defined projects that need expert execution, I’m the right person to bring your vision to life.

    ASR Engineer
    mai 2023 - Aujourd'hui (3 ans et 1 mois)

    Build Voice Assistant and integrate Language Model to boost accuracy:
    . Train Conformer architecture to build robust ASR system for French, Arabic, Turkish and Hebrew languages.
    . Training models that handle multi-lingual complexities
    . Build tokenizers for rich morphological languages.
    • Experiment with different n-gram orders to find the optimal balance between accuracy and
    computational cost.
    • Use techniques like interpolation, ngram shrinking, pruning, and model interpolation to improve performance. Improve language model scores and perplexity:
    • Employ data augmentation techniques such as backtranslation and noise injection. Minimize word error rate (WER) and sentence error rate (SER):
    • Utilize beam search decoding, lattice rescoring with language models, and confidence estimation.
    • Experiment with different token lexicon patches to improve the accuracy of word recognition. Optimize text-to-speech systems:
    • Use pretrained models to recover diacritics for languages like Arabic. Create statistical tokenizers:
    • Implement techniques like character-based, word-based, and subword tokenization.
    • Consider using OpenNLP tokenizer for languages like Arabic. Resolve client bug tickets:
    • Conduct thorough investigations to identify root causes.
    • Debug code and implement appropriate fixes.
    Implement research paper solutions:
    • Explore neural machine translation models, self-supervised learning techniques, and transfer learning approaches..

    Tasks:
    • Scraping without being flagged as a bot using rotating proxies approaches
    • Developing scripts and code to automate the data extraction process, and handling data in a way that is accurate by connecting spiders with Django views.
    • Train classificationsNLP model for topic modeling using Pytorch
    • Serve Machine Learning models to production using TorchScript and TorchServe
    • Use the GPT3 model for data collection and augmentation to generate meaningful queries from random
    keywords.
    • Dockerise microservices cloud platform Cloud Run service.
    • custom NLP models on Vertex AI (Batch prediction service)
    • Automate deployment process using terraform .
    • Design and configure database for the backend part using Django Google
