Linnea F.

I joined Upwork at the dawn of ChatGPT, offering translation services while exploring AI’s potential. Over the past 4 years as a freelancer across multiple platforms, my work has evolved from translation and content writing to AI evaluation, data curation, and technical AI development. This journey led to a full-time AI Engineer role, where for over a year I designed, built, and deployed AI solutions from scratch, earning $80K/year in the process. I work across the full AI project lifecycle: - Evaluation & Quality Assurance: Assessing AI outputs for accuracy, relevance, clarity, and instruction-following - Problem Discovery: Analyzing business challenges and designing the AI approach - Data Work: Gathering, cleaning, and compiling custom datasets - Model Development: Training and fine-tuning models, including LLMs, for specific needs - Deployment:** Running solutions locally or in the cloud for real-world use Projects I’ve contributed to or led include: - Research agents that collect and structure domain-specific data - Expert agents that write authoritative content and answer in-depth questions - Custom anonymization models to protect user privacy - Python automation pipelines to streamline prompt engineering and evaluation Now back on Upwork, I apply the same mix of prompt engineering expertise, analytical thinking, and technical problem-solving to new projects, whether evaluating AI systems, improving model quality, or building solutions independently or as part of a team.
