Hey, I'm Max.

I started OnlineOrNot in early 2021: https://onlineornot.com

There's no massive team, no investors looking for growth at any cost, just me, running a self-funded, sustainable business from France.

Open invitation to talk shop: you can always reach me at [email protected]

I also blog about running a SaaS: https://maxrozen.com

I'm a Software Engineer originally from Sydney, Australia with a passion for the Internet.

I've worked at Atlassian and am now at Cloudflare, building the Workers platform.

shops you actually want to work at don't have "mandatory conditions", they have criteria that match an ideal candidate.

if you think you can do the job, track down the hiring manager and convince them.

The job has never been about "writing code". You're there to solve problems for the business.

I'd reach out to people you've worked with before and ask if they need help.

Not _quite_ in this case, since the free plan improves everyone's experience: https://blog.cloudflare.com/cloudflares-commitment-to-free/

I used to keep all of OnlineOrNot's timeseries data entirely in a hot postgres db with the rest of the relational data.

Used to take a few seconds to get a week's uptime data and do some useful analysis.

Since moving to Clickhouse I think I can grab a full year's data in around 200ms (probably less if I try optimising it). Still completely blows my mind everyday.

Something doesn't add up between the pricing and the core pinning for me (or maybe I misunderstood):

Say you're using a m8i.large (2 vCPUs, $0.043/hr on spot pricing). Is the article saying you dedicate a whole physical core to one browser or am I totally misunderstanding here? If so, are you taking a loss on every browser hour?

I worked on a project that used yarn from the early days all the way up to v3, it's slow as hell, but it works. They also have the supply chain protections.

Eventually we snapped and migrated to pnpm. Installs (both in CI and on local dev machines) are significantly faster. Turned out to be about a day's work to migrate with an LLM's help.

the best part is Downdetector is inaccurate as hell - if AWS is genuinely down, folks get curious and search other providers, causing Downdetector to mark them as down too

Charging by the hour was one of the worst things for my career (was just starting out). Never realised at the time that I was subconsciously doing a slower job and not trying to make it faster or really improve until I left.

You can already ship single executables, my product's CLI is a Node single executable application

This is incorrect.

You preface with PUBLIC_ to expose them in client side code.

Still OnlineOrNot (https://onlineornot.com/) - I've been working on adding more and more configurability to the browser checks feature.

More recently, I've made it so you can drop your existing playwright test suites into the code editor, and it'll Just Work.

A whole bunch more work to do around that, but I think letting folks drop code in makes more sense than continuously updating the UI.

A CV that tells me what you did, and what benefit it had to your employer.

I'm only impressed by side projects if they had users and/or MRR - something serious that proves you worked on it long enough to have something to show for your efforts

At the same time I wouldn't skip a candidate for not having a portfolio - a full time job is enough
