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. Tech: Python · Django · FastAPI · React · Next.js · Vue.js · TypeScript · JavaScript · Node.js · Swift · Kotlin · React Native · Flutter · PostgreSQL · MySQL · Redis · ClickHouse · AWS · GCP · Docker · Kubernetes · Solidity · Web3.js Send me a direct message to get a free 30-minute session to map your architecture, align on tech stack, or define your MVP roadmap before development begins.

For 15+ years, I’ve built web and mobile apps that run reliably in production — not just demos. Clients come to me when systems need to stay stable under load and behave predictably. I focus on architecture and delivery that actually work in real conditions. I’ve delivered 100+ projects, including high-load systems with millions of users. My experience covers VPN & cybersecurity solutions, banking software, AI tools, real-time tracking systems, and scalable mobile/web platforms with complex functionality — along with other non-trivial systems. Tech: • Swift (UIKit / SwiftUI), Kotlin (Jetpack, Coroutines) • React (Next.js), Vue • Node.js (NestJS / Express), PHP (Laravel / Yii2) • WebSockets, TCP/UDP • REST / GraphQL APIs • Stripe / PayPal • Firebase, Amplitude, AppsFlyer, RevenueCat • OpenAI, Gemini, Claude, vector DBs • JWT, OAuth2, encryption, secure storage I handle architecture and key decisions myself. If needed, I involve additional developers — always transparently. Process is straightforward: define scope → plan → build → test → release → support. No overengineering, no surprises. If you need help with a new project or improving an existing one — send a short description, and I’ll quickly outline the best way to approach it.
