The Hybrid Method

Describe an idea. I build a working first version. Then we decide.

For founders, small businesses and teams who want something real online, fast. No spec, no deck: a working first version within days, and only then do we decide whether to continue.

Things I’ve built

Real projects, real screenshots. Every one of them is open to try.

  • Live demo

    Aurora

    A creative-studio landing: a cursor-reactive wordmark over a flowing silk field in aurora tones.

  • Live demo

    Biome Synth

    A pixel world you play: five worlds, each with its own genre, and every creature is an instrument.

  • Collaboration

    Shiluv clinic: room booking

    A booking system for a clinic that rents out its treatment rooms: renters pick a day and a free slot across five rooms and a shared space, and the staff run bookings, fixed slots and requests from a back office. Live on the clinic’s site.

  • Live demo

    Wandcraft

    A pixel-art roguelite where you program your wand: slot spells and relics into it, then fight through dungeon rooms. Built from scratch in Godot as a mobile game, and playable in the browser.

  • Live demo

    Od Sevev

    A satirical Hebrew idle game about Israel’s endless elections: pick a list leader, collect shekels, pay off coalition partners and go to the polls again and again. Free, no sign-up, satire on everyone. Built in Godot.

    Bloom Garden

    A webcam hand-gesture game: move your hand to coax flowers open, then pinch to pluck them into a bouquet. MediaPipe hand tracking, with a mouse fallback.

  • Live demo

    Dira

    An apartment-search tool: collect every place you have seen, rate and compare them side by side, and work out the all-in cost with purchase tax and mortgage.

    Trip Planner

    Plan a trip end to end: itinerary and stops, stays and transport, budget with a currency converter, a checklist and a destination guide.

  • Live demo

    Clinic site

    A site for a private family doctor: a calm, clean page that explains the services, builds trust, and lets a patient book or leave details without a phone call.

  • Open source

    MDP

    An open-source Markdown compiler for agent-written content: one declarative source renders deterministically into design-locked slides, pages, and flyers. Ships as Claude Code and Codex plugins, with a live in-browser playground.

  • Open source

    Catalogue Orchestrator

    An open-source, local-first video orchestrator: point it at a catalogue of media plus an intent, it indexes everything, retrieves the right moments with RAG, and an AI agent plans an edit that a deterministic ffmpeg compiler renders into a finished cut. The AI only ever emits a validated edit list, never raw ffmpeg, so the output stays reproducible.

Process

The Hybrid Method

Three steps from idea to a version that works.

  1. Day 0 · a few lines

    Describe

    You tell me what you want, in a few plain words. Even a half-baked idea is enough. No technical language.

  2. Within days

    Build

    I build a real first version, fast, that you can open and try. Not a mockup, not a deck, a product that works.

  3. No commitment

    Decide

    Seeing something real makes it far easier to decide where to go next. No commitment.

Who I am

The hard part is knowing what to build.

Bar Moshe

I’m Bar Moshe, an independent developer. I work with people and businesses who want something real online, fast: a website, a store, an internal tool that saves time, a small app, or a first version of an idea.

Today anyone can get an app from an AI tool in minutes, but you’re alone with a prompt, and the hard part was never the code: it’s knowing what’s worth building and what to leave out. I understand the need, research, write the copy, build with AI, and review everything like a developer, and I only take projects I actually want to build. If it’s not a fit, I’ll tell you up front.

Q & A

What people ask before reaching out

  • How does this actually work - when do we talk money?

    First I build a first working version. Only after you’ve seen it and decided to continue do we get into terms and payment.

  • What if I don’t know yet exactly what I want?

    Perfect - that’s most cases. Describe in two sentences the daily problem in front of you, or a product that annoys you, and I’ll build a real first version. Once there’s something to see, it’s much easier to say "yes, but…".

  • And the technical side - do I get what gets built?

    Yes. Everything that gets built is yours, and whenever you want it, I hand over the source and any access you need. You’re not locked in.

  • I’m not technical at all - is that a problem?

    The opposite. Most of my clients don’t code. If you can describe in words what you want to happen, I have enough to work with. The technical side is on me.

  • What happens after there’s a first version?

    We sit down to talk. Look at what works and what’s still missing, agree the scope for what comes next, and move at a pace that works for both of us.

  • Can we sign an NDA?

    Yes, no problem. Send me yours or I’ll send a standard template. I sign before we go deep on the idea.

    My job search is a marketing funnel, and I am the product

    How I run my job search like a marketing funnel: a CRM of plain files, a landing page for every company, and an AI agent that never forgets a follow-up.

  2. How I work

    Domain Driven Vibe Building: a shared language first, screens after

    The client can't write a spec, but they can talk about their work. Before I build a screen with AI, I build a model of the business in their own words.

  3. How I work

    Build first, talk later

    How I work: instead of opening a project with a spec and a round of meetings, I build a working version first, and we decide from the real thing.
