From competent to masterly
The chip strip is a ladder of skill. Competent means good enough, which can be faint praise. Skilled is solid and trusted. Proficient sounds measured and is common in job ads. Accomplished adds a track record of success. Masterly is the top, rare and best saved for real brilliance.
An honest rung reads better than an inflated one. Calling an intern masterly makes readers doubt the rest of the reference.
Resume and LinkedIn wording
Self-praise needs proof. Instead of calling yourself an expert, name the level and the result.
Before: "Expert in data analysis." After: "Proficient in SQL and Python; built the weekly sales dashboard used by four teams." Proficient is modest, and the detail does the bragging.

Friendly words for the person who knows
In conversation, people reach for warmer terms. A whiz is quick and clever, often with numbers or computers. An old hand has years of practice. A buff is an enthusiast, such as a history buff, who may not be a professional. Dab hand is British and friendly. Guru suggests a person others look to for guidance; outside spiritual contexts it is playful.
Mix-ups to avoid
Experienced means many years, not necessarily great skill. Qualified means certified or trained enough for a job; a qualified nurse may still be new. Genius is raw talent, not studied knowledge. Fan or buff shows love for a topic, not authority on it. Pick expert or specialist when knowledge is the point.
The opposite of an expert
Novice and beginner are neutral and kind. Amateur first meant someone who works for love rather than pay, and today it may hint at poor work. Layperson is someone outside a profession, common in medicine and law: written for a layperson. As adjectives, inexperienced and unskilled are the plain opposites.
