Work History

Apprentice AI Engineer

AI Singapore
02.2025 - Current
  • Completed a 2-month deep skilling phase focused on machine learning fundamentals, covering topics such as neural networks, natural language processing (NLP), transformer architectures, and Large Language Models.
  • Collaborating with a team of apprentices to design and implement a Retrieval-Augmented Generation (RAG) solution for AI-assisted generation of engineering documentation.
  • Contributing to the development of a Minimum Viable Model (MVM) tailored for easy deployment in offline, air-gapped environments.
  • Containerizing the solution using Docker to ensure consistent, portable, and reproducible deployments across isolated systems.
  • Implemented a CI/CD pipeline (e.g., GitLab CI) to automate linting, testing, and builds; documented the system using Sphinx to support onboarding and ongoing development.
  • Developed a model and prompt evaluation pipeline to streamline experimentation and reduce manual testing time across the team.
  • Co-developed a modular and configurable AI pipeline using Haystack, supporting rapid iteration and flexible component integration.
  • Participated in weekly technical sharing sessions to exchange learnings, present tooling updates, and help level up team capabilities.
  • Ensured reproducibility and maintainability through structured code, internal documentation, and version-controlled configurations.
  • Engaged in code reviews, debugging, and performance tuning to maintain quality and reliability across the codebase.
