Proofreading of my cover letter

Hello, would someone please have a look at my cover letter:

Dear Hiring Manager,

I would like to express my interest in the Junior Web Developer position as advertised on Kijiji’s website. I am confident that I am the perfect candidate for this position.

Being a web designer and junior developer I have a passion for all things internet and design related. I recently graduated from Red River College with a certificate in Software Development and also audited for PHP courses at NAIT.

As I was reading the task description of the posted job, I became increasingly interested. I would love to gain more experience in the field and am a motivated learner. I quickly adapt to the work methods and routines of my employers and I am a fast and motivated learner.

I have attributes that would make me an asset to your company. A knack for working both independently and as a team player, the ability to meet deadlines, and a character that is approachable, yet hardworking and self-sufficient.

I thank you for your time and consideration, and I hope to speak with you further about my qualifications. Please see my enclosed resume, and also feel free to view my online portfolio at

Yours sincerely,
Marie
