Companies usually bring me in when they need more than just code. They need systems that are stable, scalable, and built with long term product growth in mind. I work with startups and growing businesses to turn complex ideas into production ready SaaS platforms, AI powered applications, automation systems, and data driven products that perform reliably in real world environments. Most of the projects I work on involve APIs, backend architecture, automation workflows, analytics, and AI integrations where clean engineering decisions matter from day one. Clients typically hire me to build MVPs fast without creating future technical debt architect scalable backend systems and APIs integrate complex third party services reliably implement practical AI workflows and automation stabilize existing production systems improve performance, scalability, and maintainability transform fragile platforms into dependable products I focus heavily on building clean and maintainable architecture so products continue to scale smoothly as usage grows. That includes SaaS platforms with admin dashboards and subscription systems AI powered applications using OpenAI, Claude, RAG pipelines, and intelligent workflows API driven platforms with multiple external integrations analytics and data visualization systems processing large datasets fintech, healthcare, and operational platforms where reliability is critical I work across the full stack from frontend experience to backend services, infrastructure, and data pipelines ensuring the entire system behaves predictably and remains maintainable over time. Platforms I Commonly Build SaaS Platforms Startup MVPs, internal business tools, admin portals, workflow systems, and scalable subscription based products. AI Powered Systems Applications integrating LLMs, AI agents, document processing, automation pipelines, semantic search, and retrieval systems. Data and Analytics Platforms Dashboards and reporting systems handling operational data, financial metrics, business intelligence, and real time analytics. API and Automation Infrastructure Systems connecting multiple third party platforms using APIs, webhooks, queues, and automation frameworks. Core Technologies Frontend Next.js React TypeScript TailwindCSS Backend Node.js Python FastAPI REST APIs Infrastructure and Data PostgreSQL Supabase Docker CI CD Pipelines AI and Automation OpenAI API Claude API AI Agents RAG Systems Zapier Make n8n Development Philosophy I focus on building production ready systems instead of temporary fixes. My approach is centered around clean and scalable architecture reliable API first system design predictable production behavior maintainable and extensible codebases reducing technical debt early building systems that teams can confidently scale If you are building a SaaS platform, an AI powered product, a data intensive dashboard, an automation heavy workflow system, or a platform with complex integrations and need someone who understands both technical architecture and product execution, I would be happy to discuss your project.

$400M+ in transactions processed across platforms we built. 100,000+ tickets sold on a 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 40+ 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. 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, AML/KYC pipelines, cross-border payment rails, and crypto-to-fiat flows. Live integrations: BlackRock, DocuSign, Salesforce, Rail API, Kraken, SEPA Instant. Production experience, not theoretical. 🔹 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, and a React Native aviation booking system — real-world apps built for real stakes. 🔹 Web3 & Blockchain EVM smart contract UIs, DeFi protocols, hardware-encrypted crypto wallets, seed-to-sale blockchain tracking, multi-chain no-code contract execution, tokenization platforms. 🔹 AI Integration LLM integrations, OpenAI API, RAG pipelines, multi-agent workflow automation, Fathom AI analytics, ClickHouse data infrastructure. I build AI as a functional product layer, not a feature checkbox. 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. Tech: Python · Django · FastAPI · React · Next.js · Vue.js · TypeScript · JavaScript · Node.js · Swift · Kotlin · React Native · PostgreSQL · MySQL · Redis · ClickHouse · AWS · GCP · Docker · Kubernetes · Solidity · Web3.js Send me a direct message to get 30-minute session to map your architecture, align on tech stack, or define your MVP roadmap before development begins.
