What I’m working on now

A short note on what I’m doing this month. I update this page when something changes, and I always give the date.

What I’m working on in October 2026

  • Caches: from Redis to Valkey, from Valkey to Dragonfly

    I move clients’ caches from Redis to Valkey, and lately from Valkey to Dragonfly. The latest migration: the cache of a SaaS application, from ElastiCache for Valkey to Dragonfly on a plain EC2 instance with 64 GB of RAM.

  • Maintaining SaaS platforms on AWS

    I maintain two SaaS platforms on AWS, one since 2023 and the other since 2026: environments in Terraform, ECS, PostgreSQL databases, monitoring and alerts.

  • Infrastructure for a gaming community

    Since 2020 I have looked after the game server, the database and the forum of a large gaming community, on a dedicated server at OVH. I make sure the evening peak does not slow the game down.

  • This site

    I build codelevel.pl with Astro, on Cloudflare Workers, with Terraform and GitHub Actions. Since the launch in September it has gained a calculator, a sample audit report, and an analysis of Cost Explorer CSV files that runs entirely in your browser. In October: prices in euro on the English site, and a new blog post every week.

What I’m testing and comparing

  • Dragonfly in place of Valkey

    Before every cache migration I test the application with Dragonfly on staging. A vendor’s benchmark cannot tell you how a particular application, its Lua scripts and its queues will behave.

  • Hetzner and OVH after the price rises

    Since 15 June 2026 new servers at Hetzner cost more, and since 1 October OVH renews Advance, Scale and High Grade servers at higher prices. I compare them with OVH’s RISE dedicated servers, which the rise did not touch. The results go into the calculator.

What I’m reading and following

  • Last Week in AWS (Corey Quinn)

    Every week I skim AWS news with commentary that tells me straight away what will change on a client’s bill and what is just a new name for an old service.

  • Ruohang Feng’s blog (Vonng, creator of Pigsty)

    I read it selectively because he writes about leaving the cloud as someone who runs PostgreSQL and storage on his own hardware, which is exactly what I watch for when moving clients to Hetzner and OVH.

The idea for a page like this comes from Derek Sivers: nownownow.com. Want to talk about something on this list? Email me.
