##  メール



**Letter from Jerry Liddell**

Dear Ms. Foster,

I am writing to apply for the position of **AI and Machine Learning Solutions Sales Representative** at DNP Tech, as advertised in the *Burnaby Times* on October 11. I believe my experience and skill set are well suited to the job requirements, and I am confident I can contribute to your sales team.

I have nine years of experience in sales. Five of those were in the IT industry at Faber & Kent Systems, where I was responsible for B2B sales of AI-related products. I then spent four years at Arc Dynamics, a major automotive parts manufacturer, where I focused on solutions combining digital control systems and AI products.

I have consistently met sales targets and have developed strong skills both as an individual contributor and as an area sales manager. I am confident in both solo and collaborative work.

Another reason I believe I would be a valuable asset to DNP Tech is that I have strong confidence in the quality and reliability of your AI solutions. If you are looking for someone who can clearly communicate your product’s technical value and help clients solve problems through AI, I believe I am the right person for the job.

I have enclosed my résumé for your consideration. I would appreciate the opportunity for an interview. I am best reached by e-mail during the day (jiddell@haremail.com) or by phone in the evening (555-2491).

Sincerely,  
Jerry Liddell
