Data analysis can be particularly challenging when approached as an individual, especially in smaller projects where the quantity of data available is more limited, as is the structure. Typically, a data analyst works with data that has already been gathered, cleaned, and put into shape. In more complex projects, containing millions of pieces of data, it is the responsibility of a data engineer to take care of the management and design of a database system. This role division can handicap the data analyst from independently managing big projects, which often involve complex relational databases. In the case of smaller companies or projects where the volume and complexity of the data are much lower, a freelance data analyst can be of great value by focusing on the areas in which they excel.

This research will be guided by the following question: How can a data analyst position himself/herself as an attractive option for smaller businesses or projects, while acknowledging that larger projects do need data engineering expertise?

To answer this, we will go over: Key strengths include cleaning the data, descriptive and diagnostic analytics, business reporting, and actionable insights that will go directly to decision-making in smaller and medium-sized businesses. The importance of leveraging available tools and platforms when one doesn’t have to over-engineer the databases. In such a case, a data analyst would use Google Sheets, Looker Studio, Airtable, or low-code/ no-code ETL platforms like Zapier to efficiently manage and analyze the data without overextending the database architecture. How cloud-based services like Google BigQuery, AWS Glue, and Snowflake enable the data analyst to query and analyze the data without needing such advanced infrastructure as is typically maintained by a Data Engineer.

The aim of this study is to reflect on the fact that data analysts can fill the gap that already exists for smaller businesses in giving very valuable insights and analysis, keeping within the confines of their skillset. Data analysts are able to surmount these limitations by employing tools that make data manipulation and visualizations much easier, thus providing scalable and impactful services without always requiring formal engineering support. This study gives, therefore, an overview of the practical tools and software a data analyst must have to be successful while handling small projects and bringing oneself into a strategic position in this competitive market as a freelance expert.

A data analyst is responsible for extracting actionable insights from data, often using statistical methods, visualization tools, and business intelligence software to help companies make data-driven decisions. Their core responsibilities include the following:

• Data Cleaning: Ensuring the data is accurate, complete, and usable for analysis.
• Exploratory Data Analysis (EDA): Identifying trends, patterns, and key metrics.
• Descriptive and Diagnostic Analytics: Understanding what happened and why it happened through statistical analysis and visualization.
• Reporting and Visualization: Communicating findings to stakeholders via dashboards, reports, or presentations using tools like Tableau, Power BI, or Excel.
• Data Interpretation: Transforming raw data into meaningful insights that align with business goals.

In turn, it is the responsibility of the data engineer to architect and set up the pipelines, manage the flow of large datasets, and create the infrastructure to store, transform, and move the data. Data engineers normally work with relational databases, big data architectures, and ETL processes in order to guarantee that data becomes available and structured in an analyzable way.

This is important to note when trying to understand what a freelance data analyst can deliver value from without having to manage complicated infrastructure setups, which would normally require a data engineer.

Smaller projects allow the impacts of a data analyst to be greater without requiring a full setup infrastructure for large-scale data operations. Smaller businesses may not deal with massive datasets, allowing a freelance data analyst to:

• Deliver Insights without extensive engineering: Smaller data usually doesn’t need such an extensive database management that larger-scale data projects require. This frees the analyst to focus on analysis rather than building complex data pipelines.
• Adaptability and flexibility: The services that an analyst may extend to a particular business may be adapted based on things such as customer segmentation, sales analysis, or operational efficiency metrics. Smaller organizations have a more direct access to the decision-makers which helps to a faster mobilization of resources based on data findings.
• Use of accesible tools: A large number of BI and analytics tools today, such as Google Sheets, Airtable, and Looker Studio, can handle quite efficiently moderate volumes of data with no deep technical competencies in database management or cloud computing needed by your analysts. We will explore these on the “tools and platforms for freelance data analysis chapter”.

Smaller and medium-sized businesses may not have either the budget or the need to invest in a full-time data engineering team. Large corporations usually require highly complex systems to manage the large volume of data, while Small and Medium-Sized Business (SMBs) typically operate on smaller datasets that can be managed with more accessible tools. By hiring a freelance data analyst, such companies are provided with:

• Cost efficiency: Instead of hiring full-time data engineers and analysts, a company can contract a freelancer for specific data projects. This keeps the company’s overall cost of managing data low while benefiting from meaningful insights into data.
• Customized solutions: The freelance data analyst works more closely with the company in developing insights pertinent to the particular challenges and goals of that business. This makes the service more personal and agile compared to a larger firm’s broad, generalized approach.
• Rapid delivery: Freelance data analysts, can focus exclusively on the business’s immediate needs without the layers of bureaucracy that might slow down data initiatives in larger firms. This can lead to quicker results and actionable insights.

Large companies might be interested in big data processing and large-scale predictive modeling, whereas for a small business, it usually is about operational insights and decision-making based on manageable datasets. The following are some of the general needs that a freelance data analyst can help with:

• Customer Analysis: Many small businesses want to better understand their customers to improve marketing strategies, customer retention, and engagement. A data analyst will be able to segment the customers, analyze purchasing patterns, and give recommendations based on the same.
• Sales and Revenue Trends: Skilled freelance data analysts can show trends in sales data, track business metrics, and point out points where businesses could optimize their processes or adjust better pricing strategies.
• Budgetings and financial forecasting: The freelance data analyst can help smaller businesses project cash flow, optimize the budgeting process, and predict future financial performance based on historical trends, even in the absence of high-level financial infrastructure.
• Operational Efficiency: Data analysts can assist in inventory management, cost analysis, and performance benchmarking to ensure businesses are operating efficiently. This might involve analyzing processes to identify inefficiencies or developing dashboards for real-time monitoring.
• Marketing Campaign Analysis: Small businesses often run marketing campaigns with limited budgets. Data analysts can assess campaign performance using metrics like conversion rates, cost per lead, and return on investment (ROI), helping businesses make more informed marketing decisions.

In this section, we will explore various tools and platforms that are essential for freelance data analysts, organized by categories based on their functionality and use case.
