These are self-described interests and working strengths. Practical automation case studies are featured in the Intelligent Automation Lab below.Three business workflows I built with Microsoft Power Automate, connecting email, HR onboarding, Microsoft Teams and Excel. Explore the implementation logic and safeguards below. Exact triggers and connectors are presented as proposed patterns where not yet confirmed.
Input: Incoming important email
Logic: Identify relevant messages, inspect content, extract fields and distinguish spreadsheet updates from items needing human attention
Output: Update Excel tracker and surface exceptions
Input: New-hire data received from HR
Logic: Identify new joiners and map HR-provided fields to onboarding tracker columns
Output: Create or update new-hire Excel records for IT task visibility
Input: Upcoming tasks from Microsoft Teams
Logic: Capture relevant task details and map them to the task tracking format
Output: Add or update task rows in Excel
I use Microsoft Power Automate to connect business information to structured Excel trackers. My workflow design focuses on clear conditions, consistent field mapping, duplicate checks, human review for exceptions, and controlled access to business data.
The three workflows and platform are confirmed by my firsthand account. Trigger types, specific Microsoft 365 connectors, expressions, error handling and approval paths shown above are illustrative implementation patterns—not claims about the exact deployed configuration. No confidential emails, HR records or tenant details are published.Training and certifications listed in my CV. Individual credential verification links can be added later.
