Tech resume guide — impact-focused formatting
Technical resumes have their own conventions. Readers are usually engineers or engineering managers, and they scan for skills, impact, and honest descriptions of the work.
Lead with skills
Put a skills block near the top. This is expected in technical resumes. Group by category: languages, frameworks, infrastructure, databases, tools. Keep the list to eight to fifteen items.
Describe impact, not activity
"Built the checkout service" is an activity. "Built the checkout service that reduced average order time from roughly 90 seconds to under 40 seconds" is an impact. Technical readers want to know what changed as a result of the work.
Be honest about scale
Numbers matter in technical resumes, and inflated numbers are noticed. "Served 3 million daily users" when the actual number was 3,000 will end the conversation. Use real numbers or describe scale in honest terms.
Include projects
Projects matter for early-career candidates and for engineers who have moved into management. Describe what you built, what technologies you used, and what the project produced. Side projects count if they are real.
Length
One page for early and mid-career. Two is fine for senior engineers and engineering managers with substantial scope.
Avoid buzzwords
"Rockstar", "ninja", and "10x engineer" are not signals. They are noise. Describe what you did and let the reader decide.
List certifications honestly
Cloud certifications, security certifications, and vendor certifications belong in a certifications section. Do not list certifications you have not completed. Do not list expired certifications as current.
One more thing: link the repos
If you have public repositories or a portfolio site, include the link. A technical reader is more likely than a general recruiter to click through.
