How to Write This Resume

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 Junior Backend Developer position where I can learn new things and advance my career.

Do

Senior Junior Backend Developer with 6+ years of experience in microservices architecture and cloud-native technologies. Reduced API response times by 40% during peak traffic periods and decreased operational costs by 25% through serverless functions on AWS Lambda. Expert in Java, Spring Boot, Docker, Kubernetes, and AWS services.

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

Node.js, Java, Python Django/Flask (Intermediate), Spring Boot, Docker, Kubernetes, AWS Lambda, PostgreSQL

Do
  • Languages: Node.js, Java, Python - Frameworks: Flask, Spring Boot - Tools: Docker, Kubernetes - Database Systems: PostgreSQL

Quick Tips

  • List programming languages and frameworks separately for clarity. Focus on your proficiency level with each tool or technology.
  • Emphasize cloud-native technologies such as AWS Lambda, Google Cloud Functions, and Kubernetes to highlight your expertise in modern backend development practices.
  • Include relevant certifications (e.g., AWS Certified Developer) under skills to showcase your knowledge and commitment to staying updated with industry standards.
  • Avoid listing soft skills separately; instead, integrate them into your professional experience section by providing examples of how you have used these skills effectively.

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

Maintained legacy system codebase, fixed bugs when reported by users.

Do

Refactored legacy system to reduce technical debt by 20%, improving maintainability.

Quick Tips

  • Start each bullet point with a strong action verb like 'Designed', 'Implemented', or 'Optimized'.
  • Quantify your achievements whenever possible, using numbers and percentages.
  • Use industry-specific terms but avoid excessive jargon that might confuse recruiters outside the field.
  • Showcase increasing responsibility by detailing roles where you took on more complex projects over time.

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 Arts | University Name | Location January 2015 – May 2019 - Coursework: Introduction to Programming, World History I & II - Honors: Dean's List Fall 2017

Quick Tips

  • Start with your most recent or highest degree first.
  • Include a brief list of relevant coursework that aligns with your current job role.
  • Mention any honors, awards, or scholarships if they enhance your credibility for the position.
  • Exclude GPA unless it is above 3.5 or you are recently graduated.

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
