Alvi Chowdhury
@alvichowdhury
AI Data Trainer focused on NLP prompt engineering, model evaluation, and generative quality improvement.
What I'm looking for
I’m an AI Data Trainer with an advertising background, and I blend creativity with analytical rigor to help NLP and generative systems produce contextually relevant, human-like outputs. At Invisible Technologies Inc., I trained and optimized advanced Natural Language Processing (NLP) models in a Virtual Machine, while also developing prompts and evaluating model behavior to find failure points and improve task alignment.
I also bring a strong “maker + mentor” mindset: I onboarded and mentored new team members in data annotation, NLP training, and AI evaluation, and I collaborated with creative teams to optimize prompts and response accuracy. From subject-specific and research-intensive adversarial prompting to rigorous visual analysis across full video sequences, I consistently target quality issues others may miss, while strengthening the teams and processes around the work.
