Ask HN: Has anyone successfully pivoted from web dev to AI/ML development? 2 years ago

I've mentored senior software developers transitioning to ML - everyone comes from slightly different background and experience. Feel free to schedule an intro call to discuss your specific situation https://cal.com/studioxolo/intro.

Ask HN: Is there any software you only made for your own use but nobody else? 2 years ago

I created

- SignalsTalk[1] to study quantitative trading signals and algorithms, for my own curiosity.

- YCVerify[2] for verifying YC companies and founders. No one else is using it yet.

- Content Credentials API[3], to find the signatures of AI generated content.

I'm also working on:

- A search engine for online ads.

- A way to track grocery item prices from receipts using LLMs.

Ask HN: Machine learning engineers, what do you do at work? 2 years ago

The same job title could have very different responsibilities. I have been more of a "full-stack" MLE, I work from research and prototyping all the way to production software engineering and ML infra/dev-ops. I have also been mentoring MLEs and ML tech leads/managers - schedule a free 30-min intro call at: https://cal.com/studioxolo/intro.

Ask HN: Small teams and solopreneurs, how are you hosting your apps? 2 years ago

For static web apps like my portfolio and blog[1], I use GitHub+Netlify.

I try to use AWS Lambdas as serverless backend as much as possible, for API products like [2].

If a server is absolutely required like running a Ghost blog/newsletter [3], I use AWS Lightsail mainly because I'm familiar with AWS in general and it offers generous free tier.

Leaving Substack 2 years ago

I just moved my newsletter[1] away from Substack to Ghost over the weekend - the writing experience is better, especially SEO settings. Substack has grown way too complicated (just look at the settings page) and useless (the social features), it still prompts you to post your links to twitter/facebook anyways (implying that's where the traffic comes?). At this point Substack's value prop is non-existent.

Ask HN: One-person companies—how do you manage it all and stay sane? 2 years ago

I think the best thing about running solo is I can control my own timeline and goals. I am working on multiple projects [1][2][3][4]. Every day I write down a short list of what I want to achieve on my note-taking app LogSeq[5], and I try to finish the list. Alternating projects and the nature of work (development/research/marketing) change my rhythm and keep me learning and feeling energized.
