I've long thought that my resume sounded a little bland and generic, but I could never quite put my finger on it. Here's an example of a blurb that I had before:
Integrated our application with two retailers, one by building an order transaction processor, and another by updating our internal voucher system
It's fine, and it's all true. However, it didn't explain my contributions too well, nor did it really justify why this was even worth mentioning on my resume.
Here's what I updated that to:
Integrated the application with a large online retailer; this project aged well and grew to become a large part of the business
It still doesn't quite detail all the parts that my teammate and I worked on — we generalized incoming CSV files as the "inbox" and our CSV responses as the "outbox", we parsed the CSV files and generalized rows as "messages" and "message bundles", and we added a bunch of resilience in case certain orders were invalid. I think it's a bit better though. Since I'm in engineering, I didn't have too much to do with the business side of things going well, but we did affect the stability and long-term maintainability.
