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

Do

Senior Freelance Backend Developer with 6+ years of experience in high-performance payment systems and microservices architecture. Successfully transformed a startup's MVP into a scalable enterprise solution, handling up to 10k transactions per second. Expert in Python, Django, 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]

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 by the job description.

Real Examples

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

Don't

Python, Java, JavaScript Django, Flask, Express.js AWS, Docker (80%)

Do

Languages: Python, Node.js, Ruby Frameworks: Django, Flask, Koa.js Tools: AWS, Azure, Kubernetes

Quick Tips

  • Group technical skills by category for clarity.
  • List only the most relevant and up-to-date technologies.
  • Include cloud services and containerization tools as part of your skill set.
  • Prioritize demonstrating proficiency through experience rather than assigning subjective ratings.

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

  • Use strong action verbs like 'led', 'implemented', 'optimized', 'improved' to begin each bullet point.
  • Quantify your achievements with numbers or metrics whenever possible (e.g., reduced downtime by 75%, increased API performance by 40%).
  • Highlight significant contributions and measurable outcomes over daily tasks.
  • Emphasize the technologies you are proficient in 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

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
