Fresh Graduate | Backend Engineer 🇻🇳

About me
A brief introduction about me.
Though I'm a fresh graduate (Dec 2025), I've gained valuable experience through internships and professional work. I worked as a Software Engineer at MoMo, Vietnam's largest fintech e-wallet, handling high-traffic systems and owning end-to-end development of the Cosmos Event Reminder Service. I also completed a Full-stack Developer internship at TecAlliance, a German automotive data company.
I'm an active learner who believes in deep research and hands-on implementation. Through independent research, I built Mini DB and Mini Kafka from scratch, focusing on understanding what these systems are internally rather than just how to use them. This approach helped me realize numerous problems and trade-offs in system design, deepening my understanding of distributed systems, databases, and event streaming architecture.
I'm seeking Fresh Graduate, Junior or Associate Backend positions where I can focus on System Design, large-scale systems, and problem-solving. I love challenges and thrive on tackling complex technical problems at scale.
