When it comes to tech resumes, clarity is king. Your experience should jump off the page and showcase your skills, not drown in jargon. Focus on quantifiable achievements. Instead of saying "improved system performance," state something like "reduced API latency by 30% using Redis caching." Concrete metrics catch the eye and show real impact.

Also, don’t underestimate the power of tailored content. For every application, customize your resume based on the job description. Highlight relevant experience and skills that match what the company actually needs. ATS algorithms are notorious for filtering out mismatched resumes. If you're using tools like GitHub or contributing to open source, link those projects. Displaying code and collaboration can elevate your application significantly.
