About Puspo
Computer Science Student, Backend Engineer, and Problem Solver.
Who is Puspo?
I am MD. Ashikur Rahman (known professionally as Puspo), a passionate Software Developer and Backend Engineer based in Dhaka, Bangladesh. Currently completing my degree in Computer Science & Engineering at United International University, I have dedicated myself to mastering the art of building robust, scalable digital systems.
My journey began with a curiosity for how things work under the hood. This led me to specialize in Backend Engineering, where I architect logic, manage databases, and ensure secure data flow for complex applications.
Professional Background
As a software developer, I focus on creating high-performance systems using Spring Boot (Java), Go (Golang), and modern cloud technologies. I build solutions that are not just functional but also maintainable and efficient.
I have experience integrating complex services, from payment gateways (Stripe, SSLCommerz) to real-time communication protocols (WebSocket). My work emphasizes Clean Architecture, Domain-Driven Design (DDD), and DevOps practices.
What I Do
- Backend Development: Architecting RESTful APIs and Microservices with Spring Boot and Go.
- Database Management: Designing optimized schemas for PostgreSQL and MySQL.
- DevOps & Cloud: Deploying applications using Docker, Kubernetes, and AWS.
- System Design: focusing on scalability, security, and performance optimization.
