Data Lake platform for media analytics newsrooms

DATAAWSBIDevOps

A European media organization relied on Excel and Google Sheets to manage growing analytical datasets, making reporting unreliable and limiting business scalability. We built a centralized Data Lake with automated ETL pipelines and custom BI dashboards, enabling real-time reporting, reliable data, and faster business decision-making.

Main challenges

Business Challenge: Spreadsheet tools could no longer support reporting

The client relied on Excel and Google Sheets as the primary data source. As data volumes increased, reporting became inaccurate, slow, and difficult to trust for business decisions.

  • Inconsistent data reduced confidence in business reporting
  • Manual report preparation delayed analytical decision-making
  • Spreadsheet workflows limited reporting efficiency

Technical Challenge: Legacy spreadsheet workflows prevented automated processing

The existing environment relied on manual spreadsheets without centralized validation, making reliable reporting and automated processing impossible.

  • Spreadsheet data contained inconsistent formats and missing values
  • Multiple sources required automated ETL pipelines
  • Centralized storage was needed for real-time reporting
Legacy spreadsheet sources transformed through automated ETL workflows and centralized validation

Delivery Challenge: Unifying fragmented data without disrupting reporting

The new platform had to replace spreadsheet workflows while keeping information available and maintaining continuous reporting throughout implementation.

  • Business records had to remain fully accessible
  • Multiple source connections required coordinated implementation
  • Reporting continuity had to be maintained throughout deployment
Transition from fragmented business records and source systems to a unified reporting platform

What we did

We built a centralized Data Lake that replaced spreadsheet-based reporting with a scalable platform for analytical workflows. The system replaced Excel and Google Sheets as the primary data foundation and automatically consolidated information from multiple client sources into a single storage. Business records were preserved while data was standardized for consistent analytical processing.

To ensure the solution's reliability, we developed Airflow ETL pipelines with a transformation layer for data cleaning, format standardization, and missing-value handling. Validated data was loaded into the Data Lake and served through custom BI dashboards with real-time updates. Analysts gained direct access to reporting without manual preparation and spreadsheet-based data checks.

Automated ETL pipeline framework

Scalable Airflow pipelines automate data collection, transformation, and loading across connected sources.

  • Collects data from multiple business sources automatically
  • Standardizes formats before loading into the Data Lake
  • Validates records through transformation logic
  • Supports integration of additional data sources

Custom business intelligence dashboards

Custom dashboards provide direct access to operational and analytical business data.

  • Displays near-real-time business reporting
  • Provides direct access to validated datasets
  • Supports reporting without manual preparation
  • Delivers insights across connected business sources

Data quality and validation framework

A transformation layer standardizes business data before analytical processing.

  • Resolves inconsistent formats and missing values
  • Standardizes dates, fields, and business records
  • Preserves business information
  • Improves data consistency before reporting

Client Feedback

"Before this project, we were essentially making the same decision for everyone. Now the platform does a much better job of adapting on its own, and that's something you notice over time rather than overnight. Teams spend less time debating what should be shown to users and more time focusing on growth opportunities. It feels like we've added another layer of intelligence to the business without making the product more complicated"

Why 95% of GenAI Projects Fail — and How the Right Approach Changes Everything

A recent MIT report, The GenAI Divide: State of AI in Business 2025, reveals that nearly 95% of generative AI pilots never achieve meaningful production impact. The issue isn’t with the technology itself — it’s in how companies approach it. At YTC, we’ve analyzed these failure points closely and built our process to overcome them. 1. Misalignment with core workflows and business context One of the biggest reasons AI projects fail is poor alignment with actual business operations. Too often, solutions are designed in isolation — impressive from a technical standpoint, but disconnected from how teams truly work. When an AI system doesn’t fit within existing workflows or address real objectives, it becomes a burden instead of an advantage.

How to create a data lake for machine learning

Building a data lake might sound like a task for large tech corporations or data scientists in lab coats. However, in reality, it’s a practical and strategic move for any business seeking to harness the full potential of machine learning. If you're gathering data and considering how to utilize it for informed decisions, automation, or AI-powered services, you need a data lake. At YTC, we help businesses transform their scattered data into structured, accessible, and scalable systems. In this article, we’ll walk you through what a data lake is, why it's essential for machine learning, and how to build one the right way.

People & processes before models & algorithms: The 70–20–10 rule for effective AI transformation

People & processes before models & algorithms: The 70–20–10 rule for effective AI transformation

Artificial intelligence has become a boardroom fixture: investments are soaring, pilots are proliferating, and the promise of transformation is everywhere. Yet as the BCG research shows, the vast majority of organisations are not realising value. Only about 26 % of companies have developed the capabilities needed to move beyond proof-of-concept and extract measurable value, and just 4 % are at the frontier of AI-driven transformation. What this tells us is that the technology itself is not the barrier. The obstacle lies in people, processes, integration, governance, and culture. Why people and processes matter more than algorithms Among the most striking findings of the report is the so-called “10-20-70” distribution of focus for successful AI transformations: approximately 10 % of effort is directed at algorithms, 20 % at technology and data, and a full 70 % on people and processes. This may seem counterintuitive in an era of hype around models like LLMs and generative AI — yet the empirical evidence speaks clearly. Companies that invest heavily in people, workflows, change management, process redesign, and the human embedding of AI outperform those that focus primarily on hard tech. Even building a team using AI is more efficient now.
