I saw Joseph's work at Data Career App, the skills-based reclassification of our job listings, the data quality monitoring dashboard, and the GA reporting that ran from BigQuery into Power BI. He is strong with Excel, SQL and Power BI. The data quality work showed he is willing to spend time on the unglamorous part, checking what is in the fields before anything gets built on top of them. I would recommend him for analyst roles where someone needs to stand behind the data, not just present it.

Joseph and I worked together at Data Career App from October to December 2025. I coordinated the team across the job listing reclassification, the data quality monitoring dashboard and the Google Analytics reporting. He was reliable on delivery and straightforward to run a project with. What I valued was how he came at a brief, on the reclassification in particular, he pushed us to think about what the output meant for the person using the app, not just whether it was accurate. I'd work with him again without hesitation.

Joseph worked under my supervision in the Finance and Accounts Division at Tana Water Works Development Agency one of the leading Government Parastatals on provision of Water and Sanitation Services in Kenya, where he consistently demonstrated a strong sense of responsibility, accuracy, and attention to detail. He was particularly meticulous when it came to reconciliations and had the discipline to follow through on variances until they were fully understood and resolved, rather than simply allowing outstanding items to carry forward.
I found him very dependable, organized, and committed to delivering accurate work within the required timelines. He took instructions well, required minimal supervision, and could be trusted to follow assignments through to completion. He also worked well with colleagues and was always willing to support the team whenever required.
What stood out most was his willingness to take ownership of his work. He was not satisfied with figures merely balancing on the surface; he made an effort to understand the underlying transactions and ensure that the records were properly supported and accounted for.
He is a very valuable asset and addition to any Finance and Accounts team. I would confidently recommend him for a finance or accounting role that requires accuracy, integrity, reliability, and a strong attention to detail.
