Hire the Best JavaScript Developers
in Israel

70+ products launched and still generating revenue for their owners today. $400M+ in transactions processed across platforms we built. 100,000+ tickets sold on a ticketing product shipped from zero. 20+ countries reached by an EdTech app delivered end-to-end. I'm not listing what's possible — I'm listing what's already running in production. I'm a full stack developer and software architect based in Israel, and the CEO of a 45+ engineer development agency. When you work with me, you get a senior technical partner who understands the code and the product — and a full team behind delivery when scope requires it. 🔹 Full Stack & SaaS Development Scalable multi-tenant architectures, B2B dashboards, internal tools, and AI-integrated SaaS. We've built white-label platforms processing six-figure transaction volumes, marketing analytics systems pulling from Google, Bing, and Facebook Ads APIs into unified dashboards, and internal CRMs built on microservices and ClickHouse. Core stack: React, Next.js, Vue.js, TypeScript, JavaScript, Python, Node.js, Laravel — full stack web developer depth from database schema to UI. 🔹 Fintech & Banking This is where I'm different from most full stack developers on this platform. We've built card issuing systems, treasury management platforms with multi-signature approval workflows, AML/KYC pipelines, cross-border payment systems with multi-currency accounts, and crypto-to-fiat conversion flows. Live integrations: BlackRock, DocuSign, Salesforce, Rail API, Kraken, SEPA Instant. Production experience, not theoretical — as a full stack developer AI-focused fintech builds also power fraud detection and automated compliance reporting. 🔹 Mobile App Development Native iOS (Swift) and Android (Kotlin) for security-critical applications. React Native for cross-platform. My mobile portfolio includes a hardware-encrypted messenger with a built-in crypto wallet, a DeFi app with decentralized exchange functionality, and a React Native aviation booking system integrated with Salesforce — real-world apps built for real stakes, not UI demos. 🔹 Web3 & Blockchain EVM smart contract UIs supporting no-code multi-chain contract execution, DeFi protocols, hardware-encrypted crypto wallets, seed-to-sale blockchain tracking for regulated goods, and tokenization platforms. 🔹 AI Integration LLM integrations, OpenAI API, RAG pipelines, multi-agent workflow automation, AI-powered analytics, and ClickHouse data infrastructure. As an AI developer I build machine learning and LLM features as a functional product layer — fraud detection, adaptive workflows, automated reporting — not a feature checkbox bolted onto an existing product. When you hire me as your full stack developer, you're not getting a solo freelancer bottleneck. You're getting a senior technical lead with backend, frontend, mobile, and DevOps teams — all behind one point of contact, one contract. Whether you need a full stack web developer for your SaaS platform, a python full stack developer for a data-heavy backend, or a mobile app developer for iOS and Android — one team covers it end-to-end.

I help founders and product teams ship high-quality software quickly when the cost of sloppy delivery is too high. I am a senior full stack developer 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.
