Ahoy, fellow daywalkers! I’m Redowan Delowar, also go by “rednafi” on most platforms.

I’m currently based in Berlin and working at Wolt as a software engineer. Before this, I was exploring healthtech in the US and fintech in Southeast Asia.

I focus on backend and distributed systems, mostly at the intersection of infrastructure, databases, and observability. I deeply care about API ergonomics and contract stability, especially when teams and services scale independently. I also help teams shape their data architecture, plan for capacity, and keep observability signals flowing at scale. I like working in the open and writing about my learnings.

Recurring themes: Go, Python, distributed systems, schema-driven development, eventual consistency, resilience patterns, high availability, data access strategies, observability, SRE practices, and sci-fi.

Curriculum vitae

For the paper trail inclined, here’s my CV.

Contact

The best way to reach me is via email. I usually check it in the morning and reply within a day. Most of my work lives on GitHub. I used to be more involved in OSS, but these days the day job takes up most of my energy, so that’s slowed down. My Twitter account is gone, and now I mostly rant on Bluesky and Hacker News. Every now and then, I cross-post a few things on LinkedIn too.

Colophon

Hugo powers this blog. It’s rocking the Papermod theme with some handrolled CSS flair. I write in plain Markdown and push the content to GitHub, triggering the GitHub Actions CI, which then deploys the site to GitHub Pages.

More on the stack, deployment, and writing process if you’re curious.

  • The handle “rednafi” is just a portmanteau of my first name, Redowan, and my nickname Nafi, which my parents and a few close friends still use.
  • I like sci-fis, and my all-time favourite book is Stanislaw Lem’s Solaris.
  • When I’m not banging my head on the keyboard, I’m probably out taking a long walk through some foresty area near a lake.
  • I think through writing and not the other way around. Most of the blogs on this site take way longer to write than you’d think.
