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.

Bar Builds is the software studio of Bar Moshe, an independent full-stack builder in Israel: apps, websites and AI tools for businesses, in English and Hebrew.

What clients say

Translated from Hebrew

We came to Bar through a recommendation, and today we fully understand why he was recommended to us. … Within a few days we already had a first version, and within just two weeks we moved from an outdated system to a new system for managing the treatment rooms, fitted to the way we work.

I recommend Bar wholeheartedly.

Maayan, Shiluv clinic
The build story

It’s amazing how Bar took the idea I had in my head and made it real. As someone who works a lot with content, seeing my site come to life this quickly and this easily was an exciting experience.

Bar is a real professional, and I’ll definitely work with him again!

    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 full-stack builder in Israel. 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.

  • Who is behind Bar Builds?

    Bar Builds is the software studio of Bar Moshe, an independent full-stack builder in Israel. I lead every project myself, from the first conversation to the code, and build with AI tools under my own review. I work in English and Hebrew, with clients in Israel and remotely.

  • What can you build?

    Websites for a business, online stores, internal tools and back offices, web and mobile apps, AI tools and automations, and first versions (MVPs) of new products. Selected work is on this page, including a room booking system that runs at Shiluv clinic today.

  • How long does a first version take?

    Usually days, not weeks. For Shiluv clinic’s room booking system, the first version worked end to end on the first day of building, and the clinic moved off its old system within two weeks. A bigger product takes longer after that, but you see something working early.

  • What decides the cost?

    There is no price list. The cost depends on what the system has to hold (logins, payments, links to other systems, real customer data) and how much content and work it needs. The first version comes before any talk about money, so you can judge the price against something that works.

  • Does the first version cost anything?

    No. I build the first version for free, and you pay only if you want to continue. If you don't, its code stays with you.
