Danone, Paris | AI SOFTWARE DEVELOPER – Work Study OCT 2022 – SEP 2023
Artificial Intelligence
- Developed and pitched 4 conversational Artificial Intelligence (AI) ideas/demos to business teams and innovation coaches in France, Poland and Netherlands.
- AI Product Management - discovery, client interview, strategy, budget, and delivery.
- Saved cost and time using parameter pruning and quantization techniques like PEFT and QLora to fine-tune Llama 2 and Flan-T5 – reduced model training and time cost.
- Instruct fine-tuned Llama 2 to generate question and answer dataset from unstructured free-text data for NLP projects (PEFT and QLora).
- Implemented in-context and zero-shot learning techniques to enable pre-trained models to generalize and perform tasks outside of its training data.
- Developed custom Python code to connect a conversational AI application with Azure OpenAI, AWS Kendra, Sagemaker Endpoints, HuggingFace Transformers, Slack and Langchain, enabling seamless communication between different services.
Data Engineering
- Developed a pipeline for digital asset data using AWS cloud services (Lambda, ECR, Fargate, S3) and Docker – reducing data processing time from 2 weeks to a few hours.
- Used Python multithreading to parallelize resource-intensive operations, enabling the application to handle concurrent ETL tasks more effectively.
- Wrote unit tests and conducted thorough code reviews to maintain code quality.
- Implemented a CI/CD pipeline GitHub Actions, Docker, and ECR (managed Kubernetes) with SSO access.
