Hi, I’m Robiul Hossain — a Software Engineer focused on building scalable, secure, and high-performance backend systems.
I specialize inTypeScript,Node.js,Express.js,Python (FastAPI), and databases likePostgreSQL andMongoDB.

I work across backend development and DevOps, with hands-on experience inDocker,Nginx,GitHub Actions, and system monitoring tools likePrometheus andGrafana. I emphasize clean architecture, efficient database design, automation, and system resilience.

Currently, I am open tofull-time opportunities in backend development and infrastructure engineering.

• Specializing in backend development with TypeScript, Express.js, and FastAPI.
• Designing scalable, high-performance databases using PostgreSQL and advanced SQL.
• Deepening knowledge in system design, distributed systems, and microservice architecture.
• Strengthening problem-solving with regular DSA practice and low-level design work.
• Applying DevOps practices: CI/CD with Docker, GitHub Actions, and Nginx.
• Setting up observability stacks with Prometheus, Grafana, and structured logging.
• Managing large codebases efficiently with Monorepo strategies.
• Boosting productivity through a custom-tailored Neovim workflow.

Over the next 4–5 years, I aim to grow into aPrincipal Software Engineer, specializing in system design, backend infrastructure, DevOps, and platform reliability, while improving leadership and communication skills to drive impactful projects.
