πŸ‘‹ Hello!

I'm Hossain

A curious mind with an engineer's mindset β€” I build systems that work, scale, and respect user privacy.
Currently working on clean backend architectures, tuning systems on linux vps, and mentoring the next generation of devs.


πŸ“‚ Curious?

You can explore a full list of my projects with context and behind-the-scenes notes here:

πŸ‘‰ projects.md β€” my personal dev journal of what I’ve built, why I built it, and what I learned.


🧠 A Bit About Me

  • πŸ’» Software Engineer: with a fluid style, I move easily between stacks, tools, and mindsets.
  • πŸ”¨ I write code β€” cross-stack, mostly backend, mostly clean, sometimes weird.
  • πŸ› οΈ I believe in deep focus, and solving real problems.
  • πŸ”§ I care deeply about clean code, minimalism, and systems that don’t leak (data or memory).
  • πŸ§ͺ I learn by doing: break β†’ build β†’ repeat.
  • 🧭 Fast learner, problem solver, and experiment freak β€” I believe learning never stops.
  • 🌍 I care a lot about privacy, open systems, and tech that respects people.
  • 🌍 Live in Germany πŸ‡©πŸ‡ͺ β€” working in Telecom infrastructure.
  • β˜• Coffee helps. So does walking.

πŸ”¨ Tech Stack

  • Languages: JS/TS, Kotlin, C/C++, Python, Bash, SQL
  • Frameworks: NestJS, Express, FastAPI, Flask, Angular, React
  • DevOps: CI/CD, Kubernetes, Docker & Podman, NGINX
  • Database: PostgreSQL, Redis, SQLite
  • Other: Wasm, Git, REST, SSH, Linux

πŸŽ“ Currently Learning

  • πŸ¦€ Rust β€” diving into systems programming and memory safety
  • 🧬 Linux internals β€” mastering iproute2, nftables, and netlink sockets, ...
  • πŸ” Observability β€” working with metrics, logs, tracing, and Prometheus
  • πŸ” Networking: Privacy-focused β€” anonymous routing and metadata reduction
  • πŸ§‘β€πŸ« Teachingβ€” building a backend path from zero for self-learners

πŸ§“ Some big words

"Technology should empower, not extract."

"Code is poetry when it’s honest."

"Learn constantly. Help generously."
