I'm SO proud of how dark mode looks on my portfolio 🤩 . And even happier with #11ty for making my portfolio possible. #SSG s are the future, I'm sure of it! #WebDesign #WebDevelopment

2 purple waves overlapping each other, the one in the foreground has a light purple to darker purple gradient going downward. Above the waves is a deep dark purple, with tiny grey dots that look like stars cast across.

About me:
Backed by 15 years of experience and a drive for UX, I lead development of backend APIs and craft React frontends. From developing core microservices to refactoring products for sustainable growth, I deliver products customers can depend on.
The fun thing about learning a new language that's in its infancy is using change logs as documentation #Zig #Programming
Does anyone know of any #FOSS or open web adjacent conferences in the #UK this year that are looking for people to give talks? I'd love to do a talk about my #11tyCMS project! #Programming boosts welcome!
Ever wanted to inject your own HTML into the markdown rendering of your 11ty posts? Me too! I wrote a post about it:

I'm tired of what AI is doing to the internet and software. I'm tired of the resource scarcity, and I'm sad about the negative impact of LLMs on the #programming field and the art of development, as well as the effects its having on our #environment .
What if #GreenCoding could not only insulate our projects from the negative effects of AI, but also reduce operational costs and improve UX? My blog post talks about all of this and more, check it out!
Boosts and feedback appreciated!

God I love #TypeScript . Its so beautiful how all your code comes together when using it. Sure it can slow you down to begin with, you have to think so much harder about everything you write. But it pays off: bugs become infrequent and things feel a lot more stable!
It's been a while since I've coded in TS, and I'm glad to be getting back into it again. Didn't realise what I was missing.
I did a Google search earlier on eco friendly coding... And got results from #LLM written posts 🤦♀️ . Sigh. #Programming #Green
Does anyone know of any #FullStack JavaScript roles? Looking to #GetFediHired #jobs #programming . Boosts appreciated <3 .
I'm fluent in JavaScript and TypeScript, with over 8 years experience in React and Node.JS, and a drive for UX and sustainable growth.
My recent achievements include:
- Building and integrating a web to PDF microservice, which is daily by clients to enable their public infrastructure meetings
- Reducing vendor lock-in and improving quest latency by 10% by developing a custom Express RESTful API, and leading the migration from Firebase.
- Building a local first, truly serverless CMS for the static site generator: 11ty (11tyCMS!)
- Reducing deployment downtime by 80% by implementing my GitHub Actions powered CI/CD pipeline and providing training for the dev team
If there's any leads on WfH jobs, I would appreciate them! See my portfolio for more: https://jessieheald.com

This is why #OfflineFirst software is vital
In my capacity as #11ty / #BuildAwesome evangelist, I wrote a post about why I'm obsessed with #SSG s:

@bkuhn Do you think that it _could_ burst in the near term, though? All this compute is absurdly expensive for something that doesn't provide the value it claims.

@eclecticpassions@fosstodon.org Honestly, good choice! Hugo was 2nd place for me, very close to 11ty, but I chose 11ty because I know JavaScript! 😆 Both very solid choices indeed 😊
Replying to
@eclecticpassions@fosstodon.org awesome stuff!! I was so tempted to check out Hugo before I found 11ty. I'm glad you've had such a good experience. The SSG life is so good 😎 .
Does anyone have any good resources or lists of resources for #OfflineFirst development? #Programming
It's been a while since I've used #TanStack Query but it's SO nice. Integrating it into Calcifer 👀 #CalciferDev
Did some more work on Calcifer today... Got the nested document rendering working nicely 😎. Very proud of how this is turning out! #CalciferDev #Programming
Any advice on #FOSS fundraising welcome!
I'm looking to setup some donation pages for my FOSS #11tyCMS project. I've looked at Open Collective and Buy Me a Coffee. Buy Me a Coffee looks like the most sensible right now: 11tyCMS's user base is tiny (for now), and it feels like any donations will likely be one offs.
Are there any platforms I should be aware of? I have also thought of Patreon but I think it might be best to wait until I have a better website for 11tyCMS, and more advertising and outreach. #programming
https://jessieheald.com/blog/the-llm-driven-death-of-stack-overflow/ I wrote a post about the death of #StackOverflow , the impact of #LLM s and #AI on learning to code. I'm starting to worry that the internet is becoming an information desert for juniors. #Programming
Making a little site to make sharing to #Mastodon a little easier.
My portfolio is Javascriptless, and I wanted to keep it that way. So thought it'd be nice to create a web app that could generate share links for Mastodon and remember your instance(s).
All you have to do is link to it with the right search params.
More on #Mastoshare soon!
Got a quick weekend project on the go. This time using #Preact which is quite fun! Keeping my dependencies and bundle sizes to a minimum! #Programming
It's concerning that many companies use AI for their hiring process. I asked a chatbot about my portfolio, and it hallucinated several skills I didn't have and missed several crucial skills I _do_ have.
Imagine the havoc that's reeking on job applications right now? The whole point of these systems is that a human can be taken out of the equation. What's the point if we still end up reviewing it because the AI can't be trusted? #AI #NoAI #Programming #Jobs
For the junior developers out there: would 1 to 1 lessons from a senior developer be helpful for you in today’s climate with AI? I’m curious… #programming boosts welcome 💖
Does anyone know of good UI libraries for #Zig ? I'm interested in building a project soon, and thinking of using Zig to do it! I know of a few, but any _recommendations_ would be welcome! #Programming
I suppose there's nothing stopping me from using a C library for that either...
I LOVE interoperability. There's something so cool about coding something that's flexible enough to work across multiple platforms. So excited to see what I can turn Calcifer into. Right now it supports Firebase, but the code is designed to be platform agnostic, so platforms like Supabase would be super easy to integrate! #CalciferDev
the insatiable urge to develop an #11ty plugin #programming
