About

I am Le Huu Hoang. and I have dedicated the last over 5 years of my career to working in the back-end development field within the dynamic environment of the banking sector. With a focus on building and maintaining high-availability and high-performance services, I have primarily utilized Golang and .NET for my projects. I am excited to share my experiences and contribute to future endeavors.

My experience includes developing responsive websites, implementing RESTful APIs, integrating third-party libraries, and optimizing web applications for performance.

What sets me apart from other developers is my ability to work effectively in a team environment and my commitment to delivering projects on time and within budget. I am a quick learner and I am always willing to take on new challenges to expand my skill set.
