A system
that works.
I am Oren Grafi, and Melogix is me: a software engineer who builds products, runs them himself, and builds systems for businesses and organizations to the same standard. The products here are running now with real users, and the case files tell what was built and where each system stands today.
Running now.
Three products I built from scratch and run myself: engine, apps, website, payments, updates and support. They are the reason you can trust what I build for others.

For example: type akuo, then space. It becomes the Hebrew word for hello.
What I built here
- One detection engine, shared by Windows and Mac
- 683 automated tests, and zero false corrections as a condition for every release
- Business licensing and organization-wide rollout, even without a network connection
- Signed self-updates
- A bilingual website, free tools and a control panel
02RedSightREDSIGHT · 2025A security scanner for systems that were built fast. It does not stop at warnings: it proves what is actually exposed and produces a report you can act on.WebLive

What I built here
- A scan engine that proves real exposure, with no external tools
- A security score and a clear report for someone who is not a developer
- Customer area, payments and subscriptions
03BABotBABOT · 2025A chat bot for online stores: it answers customers on the site, on WhatsApp and on Telegram, and hands over to a human when needed.WebLive

What I built here
- A bot that learns the store's own knowledge
- Shopify and WooCommerce connections
- Several stores and live conversations, in Hebrew and English
Status reflects the live version and is updated by hand
What I build for clients.
The same standard I hold my own products to, applied to your system. Whether it is still an idea or has been running for ten years.
- 2.1
Systems for running the business
When Excel and WhatsApp stop holding: one system for customers, tickets, field staff and inventory.
For exampleTechCall: service calls, technicians and reports
- 2.2
Web, mobile and desktop apps
From the first screen to the app stores, including payment, installation and updates.
For exampleKavanati: Windows and Mac from one engine
- 2.3
Content systems and enterprise portals
Websites and portals for large organizations: content, customers, permissions, and meeting security requirements.
For examplePortals in banking, healthcare and telecom
- 2.4
Rescuing existing systems
A system that was built fast and got stuck, a long-running system on old technology that nobody is left to maintain, a vendor who disappeared, code nobody dares to touch. I step in, learn it, stabilize it, and continue from there.
For exampleAn old .NET system with no maintainer, or an app built with a rapid-build tool that reached its limit
- 2.5
Security and launch readiness
Before the system meets real customers: what is exposed, what is not backed up, and what happens the day something goes down.
For exampleRedSight, a Melogix product built for exactly this
- 2.6
Websites that explain a complex product
When the product is good but hard to explain: a site that an enterprise buyer understands and believes.
For exampleBlackbar, a site for an enterprise information-security product
From the field.
Systems, websites and products for businesses, and products of my own. Every case file covers what hurt, what was at risk, what was delivered, and what I worked with. Large organizations too, without details.

How I work.
Three stages, no surprises. At every point it is clear what the next stage is and how much it costs.
- 01
A message
You write to me on WhatsApp, two or three lines. I come back with focused questions or an offer of a short call. No charge.
- 02
Entry stage
A focused review of the system or the idea. At the end: a plan, a timeline and a fixed price. Paid at a flat fee, so you get a real answer and not a slide deck.
Flat fee, agreed before we start. The first call is free.
- 03
Build and run
Work in milestones, paid per stage. A version you can touch early, regular updates, and after launch I keep maintaining it if you want.
AlwaysA fixed price for every stage/The code and the access are yours/Documentation in Hebrew/One person accountable

Who builds it.
I am Oren. I write the code, and I stand behind it.
Since 2015 I have built systems for large organizations as an external developer, in banking, healthcare, logistics and telecom, and alongside that, systems for businesses and startups. In recent years I also build products of my own, because the best way to make sure a system works is to be the one who gets the phone call when it does not.
I work alone, and sometimes alongside people I trust. The responsibility for every project is always mine.
Write to me.
+972-53-783-6708WhatsApp or a call. Two or three lines about what you need are enough. I usually reply the same day. My hours are flexible, and sometimes I am around late at night too.
I answer, or Rotem, who works with me. The responsibility for the project is always mine.
