- Strong Python fundamentals
- Have experience on building something with LLMs (through Thesis, internship, side project, or hackathon) and can explain the concept and its objective in a simple way
Bonus points (not required):
- Exposure to vLLM, LoRA/QLoRA fine-tuning, or prompt optimization frameworks like GEPA
- Interest in financial data and regulation
