Hire the Best TypeScript Developers
in Israel

Hi, I’m Danny — a full-stack developer with 10+ years of experience, specializing in Node.js, TypeScript, and scalable web systems. That is what I have been doing so far and, recent a couple of years, I now focus on building AI-powered applications by combining solid backend architecture with modern tools like OpenAI, LangChain.js, and vector databases (Qdrant, Supabase). I don’t just build chatbots — I build AI agents that use tools, remember context, and automate real business workflows. With AI-assisted development tools like Copilot and Cursor.dev, I move 3–5× faster while still writing clean, modular code that’s easy to test and extend. Are you looking for a NodeJS expert? Yes! - 10+ years of exp in NodeJS/Typescript - REST-style and GraphQL APIs for mobile/web apps - Scripts to automate business flows I am committed to Drawing use-case diagrams closely connected with actual clients. Pulling robust db schema, architecturing the whole system. Composing tests cases for each use-case. Write clean, modular, and maintainable code. Maintaining and extending system module by module. Strong communication skills and ability to work in a fast-paced team environment. Capable of designing complex systems from ground up. You can rely on me with AI argmented system Backend - Express/NestJS Frontend - VueJs and React, React Native, ElectronJS DB - MongoDB, PostgreSQL, MySQL Deployment - AWS/Heroku/Azure/GCP I would be happy to add value to your team, product and company for great success.

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, c#, go, rust, 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.

I help founders and product teams ship high-quality software quickly when the cost of sloppy delivery is too high. I am a fractional CTO and hands-on software architect with 20 years of experience across SaaS, web, mobile, DevOps, databases, AI, and product engineering. I can lead a team, pair with your existing developers, or work entirely independently from elicitation through production delivery. I am strong at elicitation and continuous communication. I can take an unclear product goal, extract the real requirements, keep the feedback loop tight, and turn ambiguity into small testable decisions. My default way of working is XP: TDD, BDD, small releases, CI/CD, automated checks, and clear acceptance criteria. I use AI agents heavily inside that engineering loop. With agents, I can multiply my implementation speed many times while still keeping the work grounded in tests, specs, review gates, and evidence that the behavior is correct. Thousands of tests are no longer an enterprise luxury. With the right architecture and agent workflow, they are one of the fastest ways to keep delivery speed high. I work by the scientific method: identify the riskiest assumption, make it testable, run the smallest useful experiment, and let evidence drive the next step. The goal is production-ready software: maintainable code, real tests, deployment discipline, data safety, and behavior that can survive real users. A proof-of-concept is useful only when it proves the path toward that standard. Recent relevant work: - Software architect for an online fitness platform, with feature delivery and technical leadership for backend and web developers. - Public PostgreSQL tooling for schema diffing and migration parity. - XP-style CI/CD for a TypeScript MCP/reporting service, including tests, coverage, hardening checks, contract review, prompt/tool evaluation, deployment, and live verification. - Actor-based high-load architecture and media delivery/storage architecture work. - AI prompt evaluation and test harness work for healthcare SaaS. Good fit for: - fractional CTO / architecture review - TypeScript, Node.js, React, PostgreSQL - AI-assisted development with real tests and guardrails - legacy modernization, delivery stabilization, CI/CD, and testing strategy If you want fast software delivery with engineering discipline behind it, I can help.

I build automations, system integrations, internal business tools, chatbots, and web applications that remove manual work, connect your systems, and help your business run faster and with fewer errors. If your team is copying data between systems, answering the same messages over and over, generating reports by hand, updating spreadsheets, or repeating the same process every day, that workflow can usually be automated end to end. What I can help with: • Chatbots and conversational tools for support, lead capture, and internal workflows • WhatsApp Cloud API integrations: automated messaging, notifications, and two-way bots • API integrations between CRMs, Gmail, Google Sheets, work management platforms, and third-party systems • Business workflow automation for reports, dashboards, data entry, and internal operations • Internal tools and custom dashboards tailored to how your team actually works • Web application development (front end and back end) with clean, maintainable code • Web scraping from complex, dynamic, or login-based websites, with sessions, retries, and pagination • Data cleaning, matching, deduplication, validation, and structured exports My approach is simple: Manual process to structured data to automation logic to reliable system to deployment and handover. I do not just write scripts. I build systems that solve real business problems and keep running after delivery. Tech stack: Python, Node.js, JavaScript, TypeScript, FastAPI, Flask, Vue, Playwright, Selenium, WhatsApp Cloud API, Make and Integromat, REST APIs, Google Apps Script, AWS, GCP, Terraform, Docker, MongoDB, PostgreSQL, Redis.
