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.

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

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.
Objective: I am a hard-working individual looking for a Python Developer position where I can learn new things and advance my career.
Senior Python Developer with 6+ years of experience in scalable backend systems. Reduced deployment time by 50% through automated testing pipelines. Expert in Django, Flask, and Kubernetes orchestration. Passionate about mentoring junior developers and ensuring code quality.
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
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%') as they are subjective and often misinterpreted. Don't include outdated technologies unless specifically required.
Real Examples
Python, Java, C++; Django, Flask; Git, Docker, Jenkins
- Languages: Python, JavaScript - Frameworks: Django, Flask - Tools: Git, Docker, Jenkins
Quick Tips
- List your programming languages under 'Languages', frameworks and libraries under 'Frameworks', and tools used for development and deployment under 'Tools'.
- Prioritize listing skills that you have actively used within the last year to ensure relevance.
- If applicable, include a separate section for soft skills but focus on demonstrating them through achievements in your experience section.
- Ensure your skill list is consistent with the job description's requirements.
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

Implemented robust testing frameworks, increasing test coverage from 60% to 95%, reducing production bugs by 35%.

Led a team of developers in managing complex project timelines and deliverables, ensuring successful completion ofmajor projectsin deadlines.
Quick Tips
- Use strong action verbs to start each bullet point (e.g., 'Developed', 'Designed', 'Optimized').
- Quantify your achievements with numbers wherever possible. Numbers speak louder than words in demonstrating impact.
- Describe challenges you faced and how you overcame them, highlighting problem-solving skills.
- Tailor your experience section for the job you are applying for by including relevant technologies and frameworks mentioned in the job description.
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

Projects

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.
