I thrive on solving real problems under pressure—especially when the data is complex and mistakes are costly. I build and maintain backend systems that logistics and operations teams rely on every day.

In my current role, I design and maintain complex PL/SQL stored procedures for logistics and financial reporting, and I rewrite critical SQL queries to reduce report response times from minutes to seconds. I also build and integrate REST APIs that automate invoice generation and package tracking, eliminating manual workflows.

I focus on stability in production: I implemented a timer-based Windows Service to replace a manual sleep loop approach, stabilizing overnight label processing. I’m comfortable diagnosing and resolving production incidents with direct impact on operational chains.

Beyond backend, I combine automation and applied AI to understand root causes and propose solutions. I’ve developed full web modernizations under my own brand, and I also built an ML metamodel for fake news detection (57,231 articles) achieving 94% accuracy and AUC-ROC of 0.98.
