# Kirsty L. > Software Engineer II @ York Solutions Location: Sunnyvale, California, United States Profile: https://flows.cv/kirsty I grew up alongside computers. As technology evolved, so did I. I experienced the early days of burning music onto floppy disks and CDs, long before streaming platforms made music instantly accessible. I saw online communities evolve from Yahoo! Answers to Reddit, and social networks shift from Friendster to Twitter. Living through these waves of change gave me a unique perspective: technology is never static, and the people who thrive are the ones who adapt with it. Because I grew up during this constant evolution, adaptability, especially with technology, became second nature to me. As technology continues to innovate and reshape the world, I intend to keep evolving alongside it. ## Work Experience ### Software Engineer II @ York Solutions, LLC Jan 2026 – Present Vytalize Data Engineering Team • Follows Medallion architecture (Bronze, Silver, Gold) data layers to ensure clean and reliable datasets. • Currently, I am • Implementing ELT workflows using dbt to build transformation models. • Developing scalable data pipelines using PySpark and Databricks to ingest, transform, and prepare large datasets for reporting. ### Software Engineer @ York Solutions, LLC Jan 2024 – Jan 2026 AI Summit Team (JAIME Model): • Worked with the tech stack: Python, Typescript, Angular, PostgreSQL, & LLM models such as Grok, Gemini, and GPT-4o • Helped engineer an AI-driven technical interviewer to assess York interview candidates' coding skills and problem-solving abilities. • Designed and optimized prompts for GPT-4o to enhance question generation and response accuracy. • Leveraged Groq Whisper for high-precision transcription, ensuring accurate capture of spoken language even in challenging audio conditions. • Implemented atomized requests for LLMs, ensuring effective communication through single-sentence responses and boolean values.
