About
Raphael Ben-Hamo
Founder of Yeshivsher · Senior Software Engineer
I'm a software engineer with 10+ years of development experience. I built Yeshivsher around one idea: a senior engineer who takes end-to-end ownership — without the overhead of a big company.
Here you talk directly to the person who writes the code. I personally lead every project, from the first call to launch, and the team scales to the size of the job. No salespeople, no account managers.
I work mostly with React and Next.js, Node and Python, and cloud infrastructure on AWS and GCP — and I build AI systems and AI agents that make it to production, not just to a demo.
What's different here.
Talk directly to whoever is accountable
No salespeople, no account managers. Whoever takes the first call is accountable for what gets built.
Something that works, not a demo
Tests, automation, monitoring and security from day one. Code your next developer can pick up.
AI speed, senior judgment
We build with the most advanced AI tooling, with engineering review on every line.
Full transparency
Transparent pricing up front, regular progress updates, and full access to your code from day one.
What I do
End-to-end development for businesses
Have an idea or a business need? We scope, build and launch — a platform, an admin system, a website or an app. You get a working product, not a task list.
AI and Agentic AI implementation
Not sure where AI actually helps? We dig in, find the places eating your hours, and build something that works — no buzzwords.
A senior engineer for your team
For teams that need reinforcement: a senior engineer who gets into the existing code, ships new capability, and advises on architecture, AI and infrastructure — no months of ramp-up.
Building a managed development team
Need more than one pair of hands? We recruit and lead developers who work under our accountability — you get a managed team with a consistent standard.
Custom business management systems
Customers in one spreadsheet, orders in another, inventory on WhatsApp? We build one management system that fits exactly how your business works — not the other way around.
MVP development for startups
Have an idea and a limited budget? We build the smallest version you can put in front of real users — on code you can keep building on, not throw away.
Who I've worked with
KorPro

Boutique Tech Studios
A software development studio in central Tel Aviv — web and mobile, machine learning, UI/UX and product design, plus optimisation of existing systems.
What clients say
Yeshivsher supports us with broad technology consulting — architecture, cloud infrastructure, and workflows across our development teams. They also ran hands-on training for the team on advanced AI development, and it showed up in our day-to-day work within the first few weeks. They speak the developers' language just as fluently as management's.
We brought Yeshivsher in to help us on some of our Full-Stack and Agentic AI development projects. The fit was excellent from day one. They're independent, sharp, and ship production-ready code — if you need a senior engineer who just steps in and gets things done, I highly recommend Yeshivsher.
When I started working on the Financial Map project, I had a very clear idea of what I wanted to build, but far less knowledge of how you turn an idea into a real technology product. Raphael helped me make exactly that connection: understanding the needs, building a structured plan, thinking through the technology and the different stages of development. He also guided me through a great many decisions and questions along the way. Beyond his professional knowledge, I really valued his availability, his patience, and his genuine willingness to help and get into the details of the project. With all my heart, I recommend Raphael!
Refael brings broad knowledge of programming languages, development tools, and AI technologies, along with the practical ability to choose the right approach for each project. He learns quickly, understands requirements with minimal explanation, and works independently to deliver complete solutions. One of his greatest strengths is his ownership of the work. Once a task is agreed upon, you can confidently leave it in his hands, knowing he will handle the details, resolve challenges, and follow through to completion without constant supervision. This allows us to focus on other priorities with confidence that the work is being handled. I would confidently recommend Refael to any organization looking for a capable, resourceful, and dependable software development service provider.
Our own products, too
Alongside client work we built two products of our own end to end: an iPhone app and a Chrome extension for eye breaks, live on the App Store and the Chrome Web Store.
