THE CHALLENGE

Manual analysis of client financial statements.

The process of analyzing financial statements for client prospecting and credit generation was largely manual, time-consuming, and prone to errors. The goal was to automate this using AI to extract key information and populate a database.

We needed a system capable of processing vast amounts of financial data accurately and efficiently, transforming raw information into actionable insights for the sales and credit teams.

THE SOLUTION

AI-powered analysis and data population.

Developed and maintained RESTful APIs using C#/.NET Core to process financial data. Integrated AI models to analyze balance sheets, extract relevant financial figures, and store this structured data in SQL Server. This system significantly reduced manual effort and improved the speed and accuracy of client analysis.

The project required careful handling of large datasets and ensuring data integrity throughout the pipeline.

OUTCOME

+1 TB

Data processed, Q4 2024

Before writing a single line of code, I ensure I understand the problem we're trying to solve and the business impact. This involves discussions with stakeholders and analysis of requirements.

Apply SOLID principles and Clean Code practices to ensure the codebase is robust, adaptable, and easy to manage. This includes careful consideration of architecture and data models.

Focus on delivering functional increments of the software regularly. This allows for early feedback and ensures that the project stays aligned with business goals. Utilize tools like Docker for consistent deployment.

After delivery, I analyze the outcomes, identify lessons learned, and apply them to future work. This includes evaluating the effectiveness of the architecture and code quality.
