What I'm looking for

I am looking for a role that challenges me and fosters growth in AI and backend development.

I'm a dedicated Software Engineer with over three years of experience specializing in Python and Go. My journey in the tech industry has been marked by a strong focus on developing fintech and SaaS products, where I have successfully built AI-driven solutions that enhance user experience and operational efficiency. I take pride in my ability to tackle complex challenges, such as preventing revenue loss through meticulous log tracing and creating innovative payment systems for low-connectivity regions.

Throughout my career, I have worked with various technologies, including Django, Flask, and FastAPI, to architect robust applications that serve thousands of users. My recent projects, such as the AI Budget Manager and the Positive News App, showcase my commitment to leveraging technology for meaningful impact. I thrive in collaborative environments and am always eager to learn and implement new technologies that can drive success.
