I’m a highly motivated, results-oriented Software Developer with 6 years of total professional experience in full-stack development. I’ve built robust backend solutions with .NET Framework and .NET Core, and I create engaging, cross-platform frontends with Flutter. I’m driven by the chance to turn requirements into stable, user-friendly software that performs under real-world load.

In my most recent role at Software Solution Company VTECH (April 2023 – December 2025), I spearheaded the development and maintenance of high-performance mobile and web applications for a leading trading platform and entertainment service, using Flutter for cross-platform compatibility. I worked closely with product managers and UI/UX designers to translate requirements into technical specifications and features. I also optimized performance and ensured stability through rigorous testing and code review.

Before that, at ATECH in the Food & Beverage (F&B) industry (July 2020 – December 2023), I developed and maintained backend services and APIs with .NET Framework and .NET Core. I designed scalable database schemas for high-volume transaction processing and built and deployed Flutter applications for both internal staff and customers to improve operational efficiency and engagement. Across both roles, I managed the full software development lifecycle (SDLC) in an agile environment—from concept through deployment.
