Work History
Senior Data Analyst
Robert Walters
01.2022 - Current
- Joined Robert Walters directly after completing my university studies, initially as a Data Analyst within the Market Intelligence team. My role focused on producing high-quality market intelligence reports and developing, maintaining, and enhancing Power BI dashboards to support data-driven decision-making for both internal stakeholders and clients.
- As the Market Intelligence function expanded and evolved into the broader Talent Advisory offering, I played an active role in supporting the commercialisation of insights, contributing to increased revenue opportunities through the delivery of tailored advisory reports. In recognition of consistent performance, technical capability, and strong client engagement, I was promoted to Senior Data Analyst in 2025.
- In this senior role, I specialise in the creation of salary benchmarking studies, talent heatmaps, competitor intelligence reports, and in-depth market research, enabling clients to make informed decisions around fair compensation, workforce strategy, and geographic expansion. My work has supported organisations in optimising remuneration structures, identifying key talent pools, and selecting optimal locations for new offices or market entry.
- I am highly engaged in continuous learning and development, with growing exposure to data engineering and analytics technologies, including SQL, Python, Azure, Snowflake, ETL tools, and advanced data collection and validation methodologies. I combine strong analytical capability with a consultative approach, ensuring insights are translated into practical, client-ready solutions.
- In 2025, I was recognised for outstanding performance, consistent delivery of high-impact reports, and strong client retention, and was awarded the Robert Walters Top Achievers Weekend, being selected as one of 100 professionals from a global workforce of over 3,300. Backed with testimonials from managers and clients.
- Motivated, detail-driven, and commercially minded, I remain focused on continued professional growth and progression, with a strong ambition to further develop my expertise and advance within the organisation.
