Describe how a greenfield project you led provided measurable value to your organization, including specific dollar amounts.

One project I'm proud of was a new internal dashboard to help our support team see failed customer imports, and I owned the backend piece for it. Before I started coding, I sat with two support reps to understand what they were doing manually, and the biggest pain was spending about 15 minutes per case digging through logs. I built a simple service that summarized the common failure reasons and linked directly to the right records, and we rolled it out first to a small group. After launch, the team reported they were saving about 8 hours a week across four people; using the hourly cost estimate my manager used for internal planning, that worked out to roughly $25,000 a year. I wasn't the overall project lead, but I led that core component and stayed involved after launch to fix a few issues that came up in the first two weeks.

At my last job in a small e-commerce company, I helped lead a greenfield project to automate weekly inventory reports that our operations team was building by hand in Excel. I was the junior engineer on the project, but I owned the data import and validation piece, and I worked closely with our operations manager to make sure the report matched how they actually used the numbers. Before the tool existed, one analyst spent about 6 hours every week pulling data from three systems and fixing errors manually; after launch, that dropped to about 45 minutes for review. Based on their loaded hourly rate and the fact that we freed up that work every week, my manager estimated the project saved roughly $12,000 a year in labor, plus it reduced stockouts that had been costing us a few thousand dollars a quarter. What I was most proud of was that the project was small enough to ship quickly, but it had an immediate impact on a team that was doing a lot of repetitive work.
