How to Write This Resume

Expert guidelines and best practices for each section of your resume.

01

Contact

Contact

First Name Last Name City, State, Zip Code Phone Number | Email Address LinkedIn Profile URL | Portfolio URL (Optional)

General Guidelines

Your contact information is the first section recruiters see. Keep it concise and professional. Ensure your email address is appropriate (e.g., [email protected]). Include your LinkedIn profile for a comprehensive view of your professional journey. A portfolio or personal website is recommended for creative, technical, or design roles.

Avoid This

Do not include your full physical address (street number/name) for privacy reasons. Avoid including personal details like marital status, age, photo, or social security number unless specifically required in your country. Don't use unprofessional email addresses.

Do

John Doe New York, NY (555) 123-4567 | [email protected] linkedin.com/in/johndoe | github.com/johndoe | johndoe.dev

02

Summary

Summary

Professional Title Result-oriented [Role Name] with [Number] years of experience in [Key Skills/Industries]. Proven track record of [Major Achievement]. Skilled in [Key Technologies/Skills]. Committed to delivering [Specific Value] for [Target Industry/Company type].

General Guidelines

A professional summary is your elevator pitch. It should be 3-5 sentences long, summarizing your experience, key skills, and major achievements. Tailor it to the job description by using relevant keywords. Focus on what makes you unique and the value you bring to potential employers.

Avoid This

Avoid generic objectives like 'Looking for a challenging role to grow my skills.' Recruiters want to know what value you bring to them, not what you want from them. Don't use first-person pronouns (I, me, my). Keep it concise and impactful.

Real Examples

Compare a weak objective with a strong professional summary.

Don't

Objective: I am a hard-working individual looking for a JavaScript Developer position where I can learn new things and advance my career.

Do

Senior JavaScript Developer with over 6 years of experience specializing in microservices architecture and real-time web applications. Led the development of scalable payment processing systems, reducing latency by over 50%. Expert in Node.js, React, Docker, and Kubernetes.

Quick Tips

  • Quantify achievements where possible (e.g., 'Increased revenue by 20%')
  • Keep it under 5 lines for readability
  • Use strong action verbs to start sentences
  • Tailor the summary to match the job description

03

Skills

Skills

Technical Skills - Languages: [List] - Frameworks: [List] - Tools: [List] Soft Skills - [Skill 1], [Skill 2], [Skill 3]

General Guidelines

Group your skills logically (e.g., Languages, Frameworks, Tools). Focus on hard skills relevant to the job. List skills in order of proficiency or relevance. Soft skills are better demonstrated through bullet points in your experience section rather than a bare list.

Avoid This

Do not list skills you are not comfortable using in an interview. Avoid using progress bars or percentages to rate your skills (e.g., "Java: 80%"). Do not include outdated technologies unless specifically required.

Real Examples

Practical example showing do's and don'ts for skills

Don't

C++: Beginner, Python: Intermediate

Do

JavaScript (ES6+), Node.js

Don't

Adobe Photoshop 20%, Adobe Illustrator 30%

Do

Visual Studio Code, Git

Quick Tips

  • Prioritize skills that are most relevant to the job you're applying for. If a position requires Node.js and React, highlight those first.
  • Keep your list of hard skills concise but comprehensive. Aim for around 10-15 key technical skills that demonstrate your expertise as a JavaScript Developer.
  • Use active language when listing soft skills. For example, rather than 'communication', use phrases like 'strong communication abilities' or 'effective team collaboration.'
  • When describing tools and technologies, specify how you used them in previous roles. For instance, mention Kubernetes: 'Expertise in Kubernetes for efficient container orchestration and deployment.'

04

Experience

Experience

Job Title | Company Name | Location Month Year – Month Year - Action Verb + Context + Result (Quantified) - Led [Project] resulting in [Outcome]... - Collaborated with [Team] to implement [Feature]...

General Guidelines

This is the core of your resume. Use reverse-chronological order (most recent first). Start each bullet with a strong action verb. Focus on achievements and impact, not just duties. Use numbers to quantify your impact (dollars, percentages, time saved, users affected). Show progression and increasing responsibility.

Avoid This

Avoid passive language like 'Responsible for...' or 'Tasked with...'. Don't list every single daily task; focus on significant contributions and measurable outcomes. Avoid jargon that recruiters outside your field won't understand.

Real Examples

Practical example showing do's and don'ts for experiences

Don't

Wrote code to implement features for users

Do

Developed user-friendly payment processing features, enhancing customer satisfaction by reducing transaction errors from 10% to 2%

Quick Tips

  • Focus on achievements that directly relate to your specialization in microservice architecture and real-time web applications.
  • Quantify your accomplishments with specific metrics such as reduced deployment times or improved system performance metrics.
  • Highlight leadership roles, mentoring activities, and instances where you guided team members to improve project outcomes.
  • Include relevant technical details like the technologies used (e.g., Node.js, React) and how they contributed to project success.

05

Education

Education

Degree Name | University Name | Location Month Year – Month Year - Relevant Coursework: [Course 1], [Course 2] - Honors/Awards: [Award Name] - GPA: X.X (if above 3.5)

General Guidelines

List your highest degree first. If you have significant work experience, keep the education section brief. Include your GPA only if it is above 3.5 or if you are a recent graduate. Highlight relevant coursework, academic projects, honors, or leadership roles.

Avoid This

Do not include high school details if you have a college degree. Avoid listing every single course you took; select only the most relevant ones. Don't include graduation dates from decades ago if age discrimination is a concern in your field.

Real Examples

Practical example showing do's and don'ts for educations

Don't

Bachelor of Science in Computer Science | High School Name | City, State September 2010 – May 2014 - Courses: Calculus I, Introduction to Programming (Java), Human Anatomy & Physiology

Do

Master of Science in Computer Science | San Francisco State University | San Francisco, CA September 2014 – May 2017 - Relevant Coursework: Distributed Systems, Advanced Web Development with JavaScript, Microservices Architecture. GPA: 3.8

Quick Tips

  • Start with the highest degree and work backwards in chronological order.
  • Include only relevant coursework that aligns with your current role or specialization.
  • Highlight any honors, awards, or leadership roles that demonstrate your capabilities beyond just academics.
  • Keep graduation dates recent if you want to emphasize your most up-to-date qualifications.

06

Projects

Projects

Project Name | Technologies Used - Briefly describe what you built and its purpose - Highlight a specific technical challenge you solved - Link to GitHub or live demo if available

General Guidelines

Projects are excellent for demonstrating practical skills, especially if you lack work experience or are changing careers. Include a link to the GitHub repo or live demo if possible. Focus on projects that show problem-solving skills and relevant technologies for the target role.

Avoid This

Don't include trivial tutorials unless you significantly expanded on them. Avoid projects that are outdated, incomplete, or irrelevant to the role you're applying for. Don't just list technologies—explain what you built and why it matters.

Real Examples

Practical example showing do's and don'ts for projects

  • Include a brief summary of the project's purpose and the problem it solves, emphasizing any technical challenges you overcame.
  • Provide links to live demos or GitHub repositories to give hiring managers direct access to see the quality of your work.
