I'm working on Dronygon, a map of cool drone flying locations.

Well I just put it live couple of days ago, now I'm just starting to post my own locations.

Had this idea when I wanted to take my drone out but didn't know where to go. And as a plus I really wanted to learn more about working with maps and geolocation for an upcoming project, so this was a perfect way to learn it and make something useful.

To aid my process to shortlist house for purchase I am creating a web app for this.

The app will use genai to extract the details of houses listed for sale and then update my custom database.

For example I can input a youtube url and it will fetch the transcript and use llm to generate Json response based on predefined schema.

I can review and shortlist the houses based on various custom parameters using the web interface.

The mvp is done in a proprietary tech stack, I just need to port it to open source tech stack with React and FastAPI

Hi there, I'm working on something similar for the UK. Happy to chat if you'd be interested in exchanging ideas.

I'm working on a few closed source projects that are all built on https://github.com/1backend/1backend, my dream microservices platform I've had in mind for 12 years before starting to implement it.

On the frontend I'm rather happy with Angular but backend-wise I was never really happy. So it was time to build it. Been developing it for more than a year now.

Working on ʻŌlelo Honua, a free and open-source internationalization (i18n) tool that uses AI to translate app content. Now building a CLI so it can integrate seamlessly with tools like Shopify and other platforms. The goal is to make localization effortless for developers without relying on expensive translation services.

Would love feedback—especially on CLI features you'd find useful!

I've got two main projects I'm working concurrently on in my free time:

- Repairing an Apple II+. So far I've converted it to run on 230V and picked up the A2DVI to connect to modern displays. Next working on cleaning up the floppy drives and repairing the one that doesn't work.

- Reverse engineering the Tandy Z-PDA. I want to be able to synchronize with modern desktop Linux applications, and also eventually write my own PEN/GEOS applications for the PDA.

I'm working on a Dutch dictionary for immersion learning; https://hetnederlands.com. Structured outputs combined with react router renders a chain of thought on demand. With most "learners dictionaries", you're limited to the basic words. This enables getting a perfectly laid out learners dictionary explanation of any word in the entire language.

A lead generator called snappy leads: https://snappyleads.co.uk/

Input: The website of a company. Any company. Apple.com or Ycombinator.com if you want.

Output: The verified email of every Apple/YC employee we've managed to find. Works for linkedin profiles too — put a linkedin profile in, you get a verified email out.

It's currently cheap as fuck ($10/mo) because it's a hacky piece of software. It doesn't work every time, but it gets improved every 48 hours so it'll be really good soon.

We're also teaching people how to hack sales and advertising, stuff like how to get a 30% response rate with targeted cold email. Basically everyone who's bought a subscription gets a lesson once per week. I've got 10 years of experience teaching skills, so in my opinion it's cool.

Join the discord server here if you want to talk about that: https://discord.gg/2RNwH8ta4A

If you want proof that I can even write an email as good as that: https://imgur.com/a/z9gNgGH

I have a good understanding of how to create likely-correct software: https://www.osequi.com/studies/list/list.html

Now I'm learning AI/LLMs from the perspective of correctness. So far I have two 'maxims' to guide me:

- AI shines where humans struggle (for prompt engineering)

- An LLM is nothing but an API call (for software engineering with AI)

I got frustrated with the current web becoming more and more unusable and made a browser extension to fix that.

It's an addon that allows one to modify any web page behavior. You can write rules for things like redirecting reddit to old reddit or keeping youtube videos playing in the background.

It's like Tampermonkey/Greasemonkey/etc but it works on HTTP request level and can modify scripts/styles/markup before they are ever rendered making it considerably more powerful.

Currently it only works on Firefox (and Firefox Mobile) because it's the only browser that supports the necessary APIs. It's seen its first release already but the UI is a bit lacking :)

Reimagining personalized food, prepared on demand and directly from fresh ingredients, as an always available urban utility. A vertically integrated ready to eat food retail and logistics network with order of magnitude improvements to value proposition, unit economics, scalability and risk profile. Consolidating nearly a decade of R&D for US go to market, our systems are way ahead of the competition by footprint (2m²/20ft²), cost per location (~$25K), degree of automation (complete) and drone integration (integrated multi-drone airport with autonomous handover, recharge, precision recapture). Think last mile delivery aggregator with zero people in prep/packaging/pickup/(post FAA BVLOS normalization ~2Q 2026 in some areas)delivery, meaningful personalization, fresher food, and 24×7 operations. Rough complexity ~10K parts BOM. Internal manufacturing. We aim to grow at ~2× historic QSR rates right out of the gate, then accelerate. Simultaneously, spinning off a few industrial ventures filling gaps in what's available on the market we've had to build for ourselves. Prior unicorn. Currently raising for US GTM, email in profile.
