Every name, employer and institution in this sample is invented. In the builder it is laid out on one A4 page; replace each line with your own facts.
Why it is written this way
- Every point pairs an action with an effect, in figures: requests per day, milliseconds, cases a month.
- "Own" and "designed" show responsibility beyond writing code to order.
- The skill list is short and grouped, with levels where they differ.
- Mentoring and on-call appear, because senior roles ask for them.
- Company names are less important than what was built; the points carry the weight.
What to change for yourself
- Use your own metrics. If you do not have exact figures, give honest ranges and explain how they were measured if asked.
- Do not disclose anything covered by your employer's confidentiality rules; describe the system in general terms.
- Lead with the technologies the target job asks for, if you truly know them.
- With more than one notable project per job, keep the best three or four points.
What to avoid
- A wall of technology names.
- Words such as "passionate" and "ninja".
- Describing the product instead of your part in it.
Questions people ask
Should I list every technology I have touched?
No. List what you could discuss in depth. A focused list is more convincing.
Do I need a summary with four years of experience?
A three line summary helps the reader place you quickly. Keep it factual.
