I am trying to come up with achievements to put on my resume but I am having trouble actually finding anything that could qualify as such. Don't get me wrong, I am certain I am doing a very good job and my boss has told me so a few times. It just does not feel like there are achievements I can think of that are applicable to my work.
My job is to produce financial reports and tools in Excel / Access. We're talking moderately complex to very complex models here, often with quite a bit of VBA to process data and automate the reporting process. About a quarter of my work is to maintain (i.e. do small to medium changes to the reports / tools and make sure the reports show the right data) and validate reports of my colleagues and the rest is mostly report development with a bit of consulting with our internal clients (helping them understand our datamarts and OLAP cubes and how we could make information XYZ into a report).
I find that it is very hard in these circumstances to find achievements. Essentially, this could be compared to software development at its bare minimum, but we all work on different projects so it's hard for me to compare with others and say I am faster. I do think my work is generally more reliable but I have no data to support it. I know that my code is written much more efficiently than my colleagues, but that may be considered subjective (and also hard to list in a resume).
TLDR: How to write a proper resume when my actual job does not fit well with typical "achievements" ? (increased sales, increased productivity...)
