Expert tip

Doesn’t my portfolio stand on its own?

Yes, your portfolio is an important component of your application package, but it doesn’t tell the whole story. For example: What is your approach to solving thorny development problems? How do you work with a team?

An excellent cover letter for a full stack developer makes a case for your employment by answering these questions as well as highlighting the reasons you want the job and the reasons you will make a great addition to the IT department. 

It is here that you can explain your achievements or describe a platform you built and support using the tools your prospective employer also uses.

This full stack developer cover letter example will give you a blueprint for writing your own cover letter:

Cover letter header

The first aspect of your full stack developer cover letter a recruiter is likely to notice is the header. This graphic element lends a professional, visual image to your application. But more than that, it highlights what could be the most important information you have to offer: how to reach you to schedule an interview.

Include the follow in your header:

  • Full name (and your pronouns, if you are so inclined)
  • Current title or the title of the position you seek
  • Address (whether to include your street address is up to you, but your city or town is expected)
  • Best phone number with which to reach you
  • Best email with which to reach you
  • Social media and/or portfolio URLs (with Resume.io, you can link directly to your portfolio from our cover letter builder).

An email cover letter is a bit different since it will lack visual impact, but your contact information is just as important.

Cover letter greeting

We cannot stress enough the importance of starting off your full stack developer cover letter in the correct manner. How you address your reader reveals your professional demeanour and your attention to detail. A proper greeting also makes your reader take notice since you are addressing them directly.

Start with “Dear” and use the correct title and surname of your reader if at all possible. Make sure you get their honorific and the spelling of their name right. If you are unsure of their preferred title, you may substitute their full name.

As alternatives, if you absolutely cannot find the correct person to address or you are greeting a committee, you may use “Dear IT Department”, “Dear Hiring Manager” or another variation on that theme. No not resort to “Dear Sir or Madam”, or worse, “To Whom It May Concern”.

Cover letter introduction

The goal of the first paragraph of your full stack developer cover letter is to introduce your career and intrigue your reader so that they choose to read on. One way to achieve this is to bring up a project you spearheaded that relates directly to the company’s situation.

You may also choose to answer one of these questions: Who are you as a professional? What do you take most pride in? Why do you want to work here and what will you bring to the IT department? Whatever you choose, make sure you lead into the bulk of your letter, which we discuss next.

Cover letter middle part (body)

Within the middle paragraphs of cover letters, you can express your ideas for your target employer and  offer career details. Choose one or two highlights and describe your role and what you achieved. Remember employers are interested in skills and attributes in the job posting.

Try not to duplicate information or phrasing from your CV since a recruiter is probably looking at both one after the other. You may choose to include a few bulleted highlights that don’t require a lot of explanation to break up the blocks of text.

Basic mistakes in a full stack developer application letter (and how to avoid them)

The best written full stack developer cover letter can end up for naught if a small error slips by. Here are some problems to edit for and ways to avoid them.

  • Long-winded stories: If explaining an IT project takes more than a couple of sentences, save it for your interview. Recruiters are looking for quick bites of information.
  • Tonal shifts: Some IT departments are very casual and others much more formal. If you’re not sure of the company’s culture, err on the side of formality. In any case, make sure you write in your own professional voice and avoid wavering from formal to casual.
  • Punctuation and grammar errors: There’s no excuse for these when you have writing tools at hand and friends or colleagues who can help with a second read.

Key takeaways

  1. With your wide-ranging talents, you need an excellent cover letter to put all the pieces together.
  2. Use your full stack developer cover letter to speak directly to your reader, explaining why you want the job and what you can do for the IT department.
  3. A compelling introduction will entice your reader to get to the meat of your letter.
  4. Careful editing and proofreading will help prove to recruiters that you are detail-oriented.
