Senka Sostaric

I am a data‑driven professional focused on remote data analyst, administrative, and data entry work, combining strong technical tools with high accuracy and organization. Over the last year, I have built a solid analytics stack with SQL, Excel, and Power BI on top of several years working in a highly regulated manufacturing environment using ERP systems.

From my previous full‑time experience, the most important things I bring are accuracy, reliability, and comfort working with structured data in tools like SAP and Excel. I am used to following defined procedures, documenting work clearly, and making sure data is complete, consistent, and ready to be used in decisions or reports. This translates directly into high‑quality data entry, careful database or spreadsheet maintenance, and dependable administrative support.

My core technical skills are:

• SQL (PostgreSQL, MySQL): joins, CTEs, window functions, aggregations, time‑series logic, and data cleaning to answer practical business questions.
• Excel: Power Query, Power Pivot, basic DAX, pivot tables, dashboards, and advanced formulas for data transformation and reporting.
• Power BI: data modelling, DAX measures (basic), interactive dashboards, KPI tracking, and visual storytelling for non‑technical stakeholders.

For data analyst‑type tasks, I can:

• Clean and transform raw datasets.
• Explore data to identify trends, anomalies, and patterns.
• Build clear tables, charts, and dashboards that answer specific questions and track KPIs over time.
• Document the steps and summarize the main insights in simple language.

For administrative and data entry roles, I offer:

• Fast, precise data entry into spreadsheets, databases, or online systems.
• Careful record‑keeping, version control, and file organization.
• Strong attention to detail on repetitive tasks without losing focus.
• Clear written communication and responsiveness in a remote environment.

I am fluent in English and Spanish and used English extensively in my technical training and prior roles, which helps in working with international teams and English‑language documentation. On Hubstaff Talent, I am looking for clients who need someone who is meticulous with data, comfortable with analytical tools, and able to support both everyday operations and deeper data questions.
