I am a backend developer with 4 years of experience building e-commerce, financial, data processing, and system optimization solutions. Throughout my studies and career, I have primarily worked with microservices, databases, operating systems, networks, and external services.

I have contributed to backend systems for products you may have already used, such as Avakids, Thợ Điện Máy Xanh, Bách Hoá Xanh, Quà Tặng VIP, and more — as well as internal systems for financial data processing, business analytics, and incentive calculation at MWG and F88. I also participated in the Security Captcha project for NAVER Vietnam.
