Over the past few weeks, I’ve been focused on building real-world solutions across Business Intelligence, Data Engineering, and Analytics.
Instead of working on basic datasets, I worked on practical use cases involving:
• performance analysis
• operational inefficiencies
• risk monitoring
• data pipeline development
The goal was simple — move beyond dashboards and build systems that actually support decision-making.
This included:
• structuring raw data into reliable datasets
• designing automated workflows using SQL
• developing interactive Power BI dashboards
• enabling real-time insights using DirectQuery
Each project was built with a strong focus on identifying gaps, improving processes, and delivering measurable insights.
All work is available here:

I’m now open to collaborating on data-driven projects in analytics, reporting, and data engineering.

Hello Contra community! 👋
I'm Emmanuel, an aspiring Data Analyst passionate about turning raw data into meaningful insights.
I'm currently building my skills in:
Excel and Power BI for data visualization and reporting.
SQL for data querying and analysis.
Python (Pandas, Matplotlib and Scikit-learn) for data cleaning, analysis and machine learning.
I'm using practical projects to strengthen my skills and explore how data can help businesses make better decisions.
Looking forward to connecting, learning and collaborating with other professionals here!
🚀 Turning Manual E-commerce Order Processing into an Automated Workflow with n8n
Manual order management may seem simple, but copying customer details, checking information, preventing duplicate orders, and sending confirmation emails can quickly become repetitive and error-prone.
I recently built an end-to-end order processing automation using n8n to solve these challenges for a handmade products store.
Here's what I implemented:
🔹 Automated Order Capture: Receive new orders through a webhook.
🔹 Data Validation & Cleaning: Validate required fields, email formats, quantities, and prices before processing.
🔹 Duplicate Prevention: Detect existing Order IDs to prevent duplicate records.
🔹 Google Sheets Integration: Automatically store valid orders and calculate order totals.
🔹 Email Notifications: Send order updates to the store owner and confirmation emails to customers.
🔹 Error Monitoring: Capture failed executions, log error details in a dedicated Google Sheets tab, and send email alerts.
The goal was simple: reduce repetitive administrative work, improve data accuracy, and make order operations more reliable.
This is what I enjoy about building with n8n — turning complex, repetitive business processes into practical automation systems.
