About
Developer with strong production experience — now expanding into applied AI and machine learning.
Reliable systems today. Intelligent apps next.
I design and maintain real-world applications with PHP, Laravel, CodeIgniter, Drupal, MySQL, SQL Server, REST APIs, and AWS. My background is practical: shipping features, fixing systems, and keeping business software reliable.
At Fanshawe College I’m studying Artificial Intelligence and Machine Learning (Co-op). I’m building skills in Python, data analysis, NLP, and ML workflows — so I can connect solid engineering with smarter products.
