Example cover letter

Written for a fictional job to show the approach. Adapt it to the real posting.

Analyzing large datasets for actionable insights is crucial for your upcoming product launch. Without effective data analysis, you risk missing out on valuable insights that could enhance your product's success. In a previous project, I implemented a PySpark solution that cut data processing time by 40%, enabling my client to make quicker, data-driven decisions. To kick off our collaboration, I suggest we conduct a thorough review of your existing dataset to pinpoint key metrics that will guide our analysis. This initial step will ensure we focus on the most impactful areas. Would you be available for a quick chat to discuss your specific data challenges?
