Hire the Best Desktop Applications Developers
in Israel

I help startups, SaaS companies, and growing businesses build production-ready web applications, backend systems, automation workflows, API integrations, and AI-powered product features. I’m a Full Stack Developer with a strong backend-first mindset. I build scalable SaaS platforms, custom web applications, dashboards, admin panels, internal tools, APIs, databases, and automation systems designed for real business use not just demos. I can help you with: • Full-stack web application development • SaaS platform development • Backend architecture and API design • React and Next JS frontend development • Node JS, NestJS, TypeScript, Python, and FastAPI development • PostgreSQL and MongoDB database systems • Admin dashboards and internal tools • Third-party API integrations • Webhooks and data synchronization • Make workflow automation • n8n workflow automation • Base44 app building and integrations • AI assistants and AI-powered workflows • Business process automation • Debugging, refactoring, scaling, and modernization I work with both custom-code systems and automation platforms. That means I can build a complete SaaS application from scratch, improve an existing product, connect multiple tools through APIs, or create automated workflows using Make, n8n, Base44, webhooks, and backend services. On the AI side, I build practical AI features inside real products and workflows. This includes AI assistants, chat-based tools, internal copilots, knowledge-based systems, AI automations, and agent-style workflows connected to actual business processes. My focus is simple: build software that is useful, stable, maintainable, and aligned with your business goals. My core technologies include: Node JS, NestJS, TypeScript, React, Next JS, Python, FastAPI, PostgreSQL, MongoDB, Docker, AWS, REST APIs, Make, n8n, Base44, webhooks, automation systems, and AI / LLM integrations. Clients usually work with me when they need someone who can understand the full picture — backend logic, frontend features, databases, integrations, automation, AI functionality, and long-term maintainability. What you can expect when working with me: • Clean, maintainable, production-ready code • Strong backend and full-stack engineering • Practical API and automation experience • Make, n8n, and Base44 workflow support • AI implementation focused on real use cases • Clear communication and structured execution • Problem-solving with both technical and business context • Reliable delivery with attention to stability and usability I can help you build a new platform, improve an existing system, add automation, integrate APIs, connect AI features, or solve technical problems inside your current product. Send me a message and I’ll be happy to discuss your project, your current technical situation, and the best next step.
