Profile: https://flows.cv/phatdang

I’m a software Engineer specializing in backend development and infrastructure, with experience in fast-paced startup environments. I’ve been involved in all stages of product development—from brainstorming and architecture design to troubleshooting production issues and integrating third-party systems.

My primary programming languages are Python and Go, and I have hands-on experience with cloud computing (AWS), databases (MongoDB, Postgres, Redis), and containerization technologies (Docker, Kubernetes).

What excites me most about software development is the ability to use technology to solve real-world problems. I thrive on tackling challenges that not only improve products and delight stakeholders but also push me to continuously learn and adapt in this ever-evolving field.

Outside of work, I enjoy reading, sharing insights on Medium, and experimenting with new technologies. I’m always eager to explore different business domains and system architectures, as I believe technology has the power to drive meaningful impact.

Technical Skills:
	•	Languages: Python, Go
	•	Databases: MongoDB, Postgres, Redis
	•	Cloud: AWS
	•	Version Control: Git (GitLab, GitHub)
	•	Messaging Systems: RabbitMQ, Kafka
