Hi, I'm Mamun Rahaman

A Biotechnology undergraduate at UIET Chandigarh (3rd Year) with hands-on experience in full-stack development, cloud infrastructure, DevOps, data engineering, and business analytics. I build production-grade systems to understand how real software works — from architecture and data pipelines to deployment and observability.


About Me

  • I learn by building real, end-to-end systems — not just completing courses
  • My work spans full-stack engineering, cloud infrastructure, DevOps automation, data engineering, and business intelligence
  • Hands-on with AWS (ECR, ECS, EC2, S3, CloudWatch), Docker, Kubernetes, GitHub Actions, and CI/CD pipelines
  • Experienced with ETL pipelines, data warehousing, SQL analytics, Power BI, and business KPI frameworks
  • I think about production from day one — clean architecture, observability, maintainability, and deployment readiness

Current Focus

  • Building DevOpsEase — a full PaaS with automated deployment, Kubernetes orchestration, release management, and an AI copilot
  • Completing RetailVista — an end-to-end retail BI platform with Python ETL, PostgreSQL data warehouse, SQL analytics, and Power BI dashboards
  • Deepening expertise in data engineering — ETL/ELT pipelines, Apache Spark, AWS Glue, and data warehouse design
  • Strengthening knowledge of cloud architecture, distributed systems, and system design
  • Preparing for roles in full-stack engineering, cloud/DevOps, and data engineering

What I've Built and Learned

  • Designed and delivered end-to-end platforms — from ETL pipelines and data warehouses to REST APIs and production dashboards
  • Built backend services with Node.js, Express.js, and FastAPI — authentication, structured logging, and error handling
  • Implemented Python ETL pipelines with Pandas and PostgreSQL for real analytical workloads
  • Applied Star Schema data warehouse design and advanced SQL analytics for business intelligence
  • Containerized and deployed applications using Docker and Kubernetes with CI/CD on GitHub Actions
  • Worked with AWS (ECR, ECS, EC2, S3, CloudWatch) and understood how production environments differ from local setups
  • Used NGINX as a reverse proxy and load balancer in containerized deployments
  • Developed a production-first mindset — thinking about maintainability, observability, and deployment readiness from day one

Goals

  • Build a career at the intersection of software engineering, cloud infrastructure, and data
  • Design and ship production-grade systems that solve real business problems at scale
  • Grow expertise in data engineering, cloud-native architecture, and platform engineering
  • Contribute to open-source projects and developer communities

Let's Connect

  • Open to collaborations, internships, and learning opportunities
  • Happy to discuss software engineering, cloud, DevOps, data engineering, business intelligence, or system design

This portfolio is actively maintained — new projects and case studies are added regularly.
