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.

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.

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?

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.
