I would love the opportunity to discuss how my experience in AI language evaluation, prompt engineering, commitment to excellence, and passion for linguistic accuracy could greatly benefit your project moving forward. My freelance work has involved direct collaboration with notable companies like Uber, as well as projects with other major tech industry leaders through contracted partnerships. I am currently freelancing to several AI software companies, where I am assisting them with very specific prompt engineering, both written and spoken for their language models. I do a lot of work on projects that require me to interact one-on-one with various chatbots through speech-to-text exchanges, as well as fine-tuning and creating detailed prompts for AI. I excel in following direct, client-specific guidelines, I possess exceptional attention to detail, and can easily and quickly adapt writing styles to specific methodological needs. With my extensive background in AI development, I am well aware of the critical importance of confidentiality and data security. Navigating through strict NDAs and security protocols has become second nature for me, and I go out of my way to ensure the protection of sensitive information while delivering exceptional results in the future. One of my key achievements with a current client has been engineering AI-generated responses through carefully crafted prompts and feedback, ensuring the most authentic Australian accent production. While I don't hold formal qualifications in linguistics, I have recently demonstrated C2 level English proficiency (scoring 84/100) on the CEFR scale, highlighting my high level of language mastery. My passion for language, paired with my AI experience, creates a unique skill set that I am excited to bring to your team's projects. Living in Perth, Western Australia, I have always worked remotely and thrive in such environments while maintaining strong team coordination and collaborative abilities.
