Software engineer and consultant, working remotely from Europe.

I am actively looking for opportunities to work remotely.

I have extensive experience with the following technologies: React, Django, JavaScript, Python, Clojure, C#, Devops. I also have an MSc degree from electronics engineering and have extensive scientific computing experience.

I have served as the lead engineer and CTO of a NY-based startup for 5 years and then set up my own consultancy firm.

Contact me at ustun@ustunozgur.com if you need help with an MVP, or with architecting and transforming your codebase, and making your team more effective.

Just to be clear, enterprise companies are using the enterprise option for security/auditing/enforcement reasons, not because OpenAI or Anthropic forbids them from buying a 200$/month plan for each engineer, right? Do they have any clause forbidding using those individual plans in a company?

I sometimes use SimplyNoise to have brown noise for sleeping or filter out distracting sounds in the office.

Also, iOS has background (white noise etc) sounds built-in: https://support.apple.com/en-us/109346 Android has something similar too?

We also installed triple-layered windows for sound insulation, but I believe it degraded the quality of the air, so sometimes have to open the windows for a few minutes before sleep to get fresh air.

Can you please share some insights as to what gives it away.

The article uses too much contrast even if not as obvious as "it's not x, it is y". Also some too punchy or over confident stuff like "that era is over blah blah".

Amusingly, you can feed it to an AI to extract the patterns that gives away that it is AI written.

I had the misfortune of having to use Azure back in 2018 and was appalled at the lack of quality, slowness. I was in GitHub forums, helping other customers suffering from lack of basic functionality, incredible prices with abysmal performance. This article explains a lot honestly.

Google’s Cloud feels like the best engineered one, though lack of proper human support is worrying there compared to AWS.

With the recent supply chain attacks that exfiltrate your .env files, it becomes important to find and shield those .env files

React hooks always struck me as object-oriented programming reinvented through the back door of functions. We started with pure components, decided we needed state after all, and ended up with magic functions that stash and retrieve state from some hidden context — essentially re-deriving this with worse ergonomics and an implicit ordering contract. Some part of it was the functional language paradigms like immutability that were popular elsewhere at the time bolted on to JavaScript.

What I find refreshing about Gea is that it doesn't fight the language. Stores are classes. Computed values are getters. State mutation is just assignment. I've been waiting for a framework that embraces the actual paradigms of the language it's written in, rather than inventing a parallel universe of conventions. Excited to try this one.

That said, I'm genuinely curious where the edges are. Was React's complexity accidental due to its architecture or was it the price of solving genuinely hard problems (concurrent rendering, suspense boundaries, fine-grained error recovery) (which by the way most consumers of the library did not care that much about)?

Does Gea's simplicity hold up as apps get complex, or will we eventually hit patterns where the escape hatch is the complexity React already internalized?

The people in charge of AI keep telling me to hate it

Anthropic’s Dario Amodei deserves a special mention here. Paints the grimmest possible future, so that when/if things go sideways, he can point back and say, "Hey, I warned you. I did my part."

Probably there is a psychological term that explains this phenomenon, I asked ChatGPT and it said it could be considered "anticipatory blame-shifting" or "moral licensing".

Probably referring to the fact that they no longer are independent, do not have a CEO and are a division of a division within Microsoft.

Founding engineer / fractional CTO — I build AI-powered SaaS products from zero to production.

15+ years, mostly at US startups as employee #1 or early hire:

- *Edge Delta* (2023-2025): Senior Engineer at this Seattle observability company. Built an AI chatbot that lets users manipulate a visual pipeline builder through natural language. Owned billing infrastructure.

- *Braid Health* (2020-2023): VP of Engineering & Principal Engineer. Integrated ML model outputs into clinician-facing radiology tools. Full-stack: React frontend, TypeScript backend, Python for ML models, cloud infrastructure.

- *Toolio* (2019-2020): Founding Engineer. Built the technical foundation for this NYC retail merchandise planning SaaS.

- *SellerCrowd* (2011-2017): CTO. Built a Django/React social network for the ad industry from scratch to 20,000+ users.

*Background:* MSc EE from Bilkent, where I did research under Prof. Erdal Arıkan (inventor of polar codes, now foundational to 5G). Conference speaker (DjangoCon Europe, Øredev).

Open to: founding engineer roles, fractional CTO engagements, or contract work on AI integration / SaaS architecture / observability systems.

I hate mosquitoes with a passion. Might be the only species that I would want eradicated from Earth.

From my experience (based in Turkey), mosquitoes seem to be getting more and more resilient. They have become an annoyance even in autumn, and I recall catching one last winter. A few decades ago, they used to only appear in late spring and summer. Anyone have a similar experience elsewhere?

A corollary of this is “Always visit when a baby is born.”

(In the first few months, if not at the hospital)

I have noticed my love and respect for my friends who never visited after our newborn declined significantly, and it has never been the same. Does anyone have a similar experience?

Sanding UI 2 years ago

Did they? My understanding is they replaced gap with padding, didn’t necessarily wrap the input with the label (which they should as you suggest)

The biggest reason this needs to be integrated is that most people simplify won’t know about this tool. Only HackerNews reader in this thread and then some enthusiasts :)

So it would result in magnitudes of more usage if it was integrated, which seems to be the path Bun is taking.

‘You either die a hero or live long enough to see yourself become the villain…’

Great that Mitchell evaded that fate by getting out of the leadership before controversial moves by Hashicorp started occurring. His legacy will be untainted.

Congrats on the wonderful journey.

Wondering how come Disqus allowed this to spin off into another company? Could they not claim that the code add belonged to them? Was it that everything was open source licensed that they could not claim rights, or were they just nice people?
