Hire the Best TypeScript Developers
in Israel

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.

I deliver n8n, Make, and Zapier workflows (leads, CRM, email, Telegram/WhatsApp, scheduling) - and I'm a senior developer when the job outgrows buttons-and-zaps. Background: senior developer & automation lead in enterprise high-tech - Java, C#, Python, APIs, SQL, Docker/VPS, CI/CD. I fix what no-code can't: custom logic, deduplication, LLM pipelines, webhooks, and 24/7 reliable deployments. --- What you get in no-code (fast delivery) --- • n8n - webhooks, Gmail, Sheets, Telegram, cron, AI nodes, custom code nodes • Make - lead routing, CRM updates, marketing ops integrations • Zapier - quick MVPs and simple business automations --- Why clients hire me instead of a "Zapier freelancer" --- I'm a senior developer first (Java, C#, Python). In enterprise high-tech I built automation infrastructure from scratch: APIs, databases, CI/CD, Docker/VPS, and production observability - not drag-and-drop tutorials. When Make/Zapier/n8n hit a wall, I don't disappear. I extend the workflow with code: • Custom services, REST APIs, and backend logic • PostgreSQL / deduplication / idempotency (same story never posts twice) • LLM filtering and scoring (Claude/OpenAI) with real error handling • Complex webhooks, auth, retries, and monitoring • VPS + Docker so it runs 24/7 without your laptop Problems simple platforms usually cannot solve cleanly: - Multi-source duplicate detection - Non-trivial business rules and branching - Heavy API orchestration beyond connector limits - AI pipelines with logging and fallbacks - Secure deployment, secrets, and recovery after failures Core stack: n8n · Make · Zapier · Java · C# · Python · TypeScript · PostgreSQL · Telegram · GitHub Actions · Docker · VPS · OpenAI/Claude API Optional scope: Playwright / API / DB test automation if you need a QA framework - say so upfront. Tell me your trigger and outcome. I'll recommend no-code only where it's enough - and code where it isn't.
