Where Data Flows with Clarity

Welcome to Data Tides, where we uncover the stories, insights, and opportunities hidden beneath the data.

Vision statement graphic for Data Tides on a light beige background with an abstract circular wave pattern in soft gold and peach tones. The left side features the heading “VISION” and the statement: “At Data Tides, I reimagine how data can be structured, visualised, and communicated to create clarity, inclusivity, and impact.” On the right, three dark purple panels highlight key themes: Clarity that Drives Action (simplifying complex data into intuitive visuals), Insights Without Barriers (building Power BI solutions aligned with WCAG accessibility standards), and Success Through Storytelling (transforming information into narratives that guide meaningful, inclusive outcomes). Decorative dotted accents appear in the lower-left corner.

Hello,

I’m Juliana

The creator behind Data Tides, a space where storytelling meets strategy and dashboards do far more than display numbers. For over 15 years, I’ve been driven by a passion for uncovering the stories hidden within data and transforming complexity into clarity. Specialising in analytics engineering and data design, I focus on shaping well‑structured models, intuitive data flows, and visual experiences that help people understand information quickly and confidently. Through Power BI, I build insights that are not only visually compelling but also genuinely accessible, following WCAG‑aligned practices to remove barriers and ensure informed decision‑making is inclusive for everyone.

Supporting a Cause Close to My Heart

As a passionate STEM Ambassador and Trustee of Technology Books for Children,I am proud to support a charity dedicated to inspiring the next generation through technology and reading.

Founded by Beverly Clarke MBE, the charity is on a mission to make technology more accessible, engaging, and relatable for children from all backgrounds. By providing technology-themed book packs to schools, organising author and Book Ambassador visits, and creating resources for educators, the charity helps young people discover the exciting opportunities that technology can offer.

Access to technology education should not depend on a child’s circumstances. Technology Books for Children works to close the digital divide and encourage curiosity, confidence, and a love of learning in STEM subjects from an early age.

Having seen the impact of the charity’s work first-hand, I am passionate about supporting its mission and helping more children access the resources and inspiration they deserve. If this is a cause that resonates with you, I encourage you to learn more about the charity, share its work, or consider supporting its initiatives.
