Explain what the company does (in several words).
Try to add why the company is impressive. Example: "the largest logistics company in Eastern Europe with clients in 78 countries."
If it's a resume file, not an professional networking profile, consider adding a link to the company website.
If it's a large company consider mentioning which team you worked on.
If it's an outsourcing company consider mentioning which project you worked on.
For completed projects it is probably best to use the past tense with the focus on accomplishments (e.g. “developed") instead of a focus on responsibilities (e.g. “developing” or “develop”).
For projects in-progress you should usually use present tense (e.g. "developing"). Mention what you have accomplished so far.
Consider having a verb instead of just a noun, e.g. “developed a frontend for a patient management system” versus just “frontend for a patient management system”, this helps clarify what your role on the project was.
When you choose a programming language, database type, or made other big architectural decisions mentioned the word “designed”.
If you both designed and developed a system, mention “designed and developed”.
Try to make sure as many of your accomplishments are measurable.
If what you built has a lot of users mention the number of users, otherwise the reader will likely assume it has very few users.
Note that common metrics in tech companies include the number of active users. These usually are 30-day active users (monthly active users), 7-day active users (weekly active users), or 1-day active users (daily active users).
If you can provide the number of active users instead of registered users because lots of people register, but don’t use the product.
If most users are inactive then you can mention just users, but a good recruiter will assume most of them are probably inactive.
If you used distributed computing and other cloud technologies (e.g. AWS) mention the technologies. I also recommend using the word “distributed”.
If you worked full-time while studying mention the word Full-Time in your role name (e.g. Software Engineer, Full-Time) otherwise the reader will likely assume you spent most of the time studying and worked part-time.
