Services
Data analysis and visualization
This service consists of transforming raw data into clear and valuable information to support strategic decision-making. As a data analyst, I use advanced visualization tools such as Power BI, Tableau and Looker Studio to develop interactive graphs, tables and dashboards. The aim is to simplify data interpretation, allowing even professionals without technical expertise to understand trends and insights intuitively. For example, I can create a dashboard that shows sales performance using bar and line graphs, making it easier for managers to analyze and make decisions.
Data cleaning and preparation
In most cases, the data collected by a company is not ready for immediate analysis, as it may contain errors, duplicates or be in incompatible formats. To solve this challenge, I offer a service based on the ETL (Extract, Transform, Load) process, in which data is extracted from various sources, undergoes transformations (such as removing inconsistencies, dealing with null values and converting data types) and is loaded into a format suitable for analysis. I use tools such as SQL, Python (with libraries such as pandas, numpy and seaborn) or specialized ETL software such as Airflow. This process is fundamental to ensuring that the data is consistent, reliable and ready to generate accurate and actionable insights.
Consultoria em métricas e KPI's
Many companies struggle to define which metrics are essential for monitoring the success of their business. I offer support in identifying and configuring KPIs (Key Performance Indicators) that are aligned with the organization's strategic objectives. For example, in the case of an online store, indicators such as conversion rate, cost per customer acquisition (CAC) and average time spent on the site are fundamental to evaluating performance. In addition, I help to build processes for the continuous monitoring of these indicators, allowing adjustments to be made as the needs of the business evolve, ensuring that the metrics remain relevant and impactful.
Análise preditiva
This service consists of applying advanced statistical and machine learning techniques to predict future results based on historical data. For example, I can develop a predictive model to estimate the future sales of a product, taking into account factors such as seasonality, consumer behavior and marketing actions. To do this, I use tools such as Python (with libraries such as scikit-learn and statsmodels), R language or even Excel models. These forecasts allow companies to make informed and strategic decisions, such as adjusting stocks, optimizing marketing campaigns or planning investments with greater precision and confidence.
Integration with your ecosystem
The main objective of these services is to help companies make faster and more informed decisions, increasing their operational efficiency and adaptability in a dynamic market. Faced with the growing demand for strategic data, my work in transforming data into insights contributes not only to optimizing processes, but also to identifying new business opportunities. By analyzing trends, patterns and behaviors, it is possible to provide support for companies to explore growth areas, innovate in their strategies and remain competitive in their sector.
