MY ENGINEERING STORY
Mobile is my main craft. Understanding the whole system is my advantage.
I specialize in Flutter, but I do not stop at the screen. My work often includes Laravel or PHP services, REST APIs, SQL and Oracle data, payment gateways, and enterprise platforms such as JD Edwards and iDempiere.
That background helps me ask better questions: where the data comes from, who owns each status, what happens when an integration fails, and how the product supports the real process—not just the ideal flow.
