A little more about the person behind the code

About Me

I was the only developer — among more than 13 professionals in the company’s internal technology team — nominated for the company’s 2024 Excellence Award. I was one of 11 names recognized for exceptional performance and consistent delivery quality.

2024 Internal Excellence Award

Personally selected by management to address a critical financial issue in a legacy Laravel PHP backend developed by external contractors. Despite being a Junior Frontend Developer at the time, I independently diagnosed and resolved the issue, implemented lasting improvements, and contributed to a monthly revenue increase of over 10%.
