Show real results
A recruiter loves seeing the direct impact of your work. When you say you increased system efficiency by 30%, it shows that you can deliver measurable results, and that's enticing to potential employers. But remember, always be truthful with your numbers.
Declare your specialization
Giving a clear indication of what languages you specialize in, like Java and C++, can make your resume more searchable. Many companies use Applicant Tracking Systems (ATS) that pick up on specific keywords related to the job description. This can get your resume in front of more human eyes.
