A good resume can make or break your chances in interviews. It’s the first impression you get to make. Keep it concise but impactful. Aim for one page if you’re junior or mid-level, maybe two if you have extensive experience. Use bullet points. Recruiters often skim resumes, so make it easy for them.

Focusing on quantifiable achievements is key. Instead of just listing skills, show how you applied them—"improved app performance by 30%" is more compelling than "knowledge of performance optimization." Use real numbers if you can. If you solved a critical bug that saved the company significant revenue, say it outright.

Also, tailor your resume for each application. It takes time, but if you can integrate keywords from the job description, your chances of getting past the applicant tracking systems (ATS) improve. Automation can work for you here—tools like Jobscan help match your resume to job postings. But don’t overdo it; make sure it still reads naturally.

Lastly, keep the tech stack up to date. If you're proficient with React, mention it, but also include any versioning details or related libraries you used. Employers want to know you’re not just checking boxes but are genuinely involved in projects. Even side projects can showcase your skills, so don’t hesitate to include those.

After all this, be ready for questions about what’s on your resume. Know the ins and outs of each project you mention. If there’s a gap or a switch in your career path, be prepared to explain that too. Every detail could lead to an interview question, so be on your toes.
