Show HN: Kacet – a freelancer marketplace with crypto-native payments
Hi HN,
I’m a co-founder building kacet, a new freelancing platform that connects freelancers and employers, with crypto as the core payment rail.
The problem I’m trying to solve is pretty familiar: existing platforms take high fees, are slow to pay out, and don’t work well for international teams. kacet is an experiment in building a simpler, more neutral marketplace where payments are borderless by default.
Some highlights:
• Crypto-native payments – fast, borderless payouts without banks, delays, or surprise freezes • Peer-to-peer contracts – clients and freelancers work directly, the platform doesn’t own the relationship Built for teams – multi-user organisations for agencies and startups out of the box • Low, transparent fees – simple pricing with no boosts, ads, or hidden take rates • No dark patterns – a calm UI focused on agreeing work and getting paid, not maximising engagement
Payments are handled by Solana smart contracts, with a React frontend (TanStack Start). We’re keeping the feature set small to validate the core workflow: post work → agree terms → get paid.
This is still early and very much a work in progress. I’d really appreciate feedback from people who have hired freelancers, worked as one, or built marketplaces before.
Site: https://kacet.com
Happy to answer any questions or go into more detail on the payment model, trust mechanics, or why I think this approach might (or might not) work.

Show HN: I quit coding years ago. AI brought me back
Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years.
Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically meditation for long-term investors.
The problem? Every compound interest calculator online is terrible. Ugly interfaces, ads covering half the screen, can't customize compounding frequency properly, no year-by-year breakdowns. I've tried so many. They all suck.
When vibe coding started blowing up, something clicked. Maybe I could actually build the calculators I wanted? I don't have to be a "real developer" anymore — I just need to describe what I want clearly.
So I tried it.
Two weeks and ~$100(Opus 4.5 thinking model) in API costs later: I somehow have 60+ calculators. Started with compound interest, naturally. Then thought "well, while I'm here..." and added mortgage, loan amortization, savings goals, retirement projections. Then it spiraled — BMI calculator, timezone converter, regex tester. Oops.
The AI (I'm using Claude via Windsurf) handled the grunt work beautifully. I'd describe exactly what I wanted — "compound interest calculator with monthly/quarterly/yearly options, year-by-year breakdown table, recurring contribution support" — and it delivered. With validation, nice components, even tests.
What I realized: my years away from coding weren't wasted. I still understood architecture, I still knew what good UX looked like, I still had domain expertise (financial math). I just couldn't type it all out efficiently. AI filled that gap perfectly.
Vibe coding didn't make me a 10x engineer. But it gave me permission to build again. Ideas I've had for years suddenly feel achievable. That's honestly the bigger win for me.
Stack: Next.js, React, TailwindCSS, shadcn/ui, four languages (EN/DE/FR/JA). The AI picked most of this when I said "modern and clean."
Site's live at https://calquio.com . The compound interest calculator is still my favorite page — finally exactly what I wanted.
Curious if others have similar stories. Anyone else come back to building after stepping away?

Show HN: Beats, a web-based drum machine
Hello all!
I've been an avid fan of Pocket Operators by Teenage Engineering since I found out about them. I even own an EP-133 K.O. II today, which I love.
A couple of months ago, Reddit user andiam03 shared a Google Sheet with some drum patterns [1]. I thought it was a very cool way to share and understand beats.
During the weekend I coded a basic version of this app I am sharing today. I iterated over it in my free time, and yesterday I felt like I had a pretty good version to share with y'all.
It's not meant to be a sequencer but rather a way to experiment with beats and basic sounds, save them, and use them in your songs. It also has a sharing feature with a link.
It was built using Tone.js [2], Stimulus [3] and deployed in Render [4] as a static website. I used an LLM to read the Tone.js documentation and generate sounds, since I have no knowledge about sound production, and modified from there.
Anyway, hope you like it! I had a blast building it.
