Professional Overview
With 10+ years of transforming complex business challenges into elegant code, I'm not just a developer—I'm your strategic technical partner. I specialize in architecting full-stack solutions that scale, particularly in the FinTech space where precision and security are paramount. My passion lies in bridging the gap between ambitious business goals and technically sound implementation.
What Makes My Approach Unique:
🏗️ The "Preventive Architecture" Mindset
I don't just build features—I design systems that prevent future technical debt. My experience in project restructuring and legacy modernization means I build with tomorrow's challenges in mind, ensuring your solution remains adaptable and maintainable.
🔁 Full-Cycle Ownership Philosophy
From initial whiteboard sketching to post-deployment optimization, I provide end-to-end stewardship of your project. This includes implementing automated testing strategies and developer-friendly documentation that makes future transitions seamless.
💡 The FinTech Specialization Edge
Beyond generic payment integrations, I bring deep domain knowledge in card processing, regulatory compliance considerations, and financial data security patterns. This means fewer implementation surprises and more business-aligned solutions.
Technical Arsenal:
🛠️ Multi-Stack Versatility
• JavaScript/TypeScript Universe: MEAN/MERN, Angular (v1-15), React, Vue, NestJS, Express
• Python Power: Django (high-scale applications), Flask (microservices), Tornado (real-time processing)
• .NET & PHP Ecosystems: Laravel, CodeIgniter, and expanding .NET capabilities
• Database Mastery: From PostgreSQL optimization to MongoDB sharding strategies
⚡ Development Accelerators
• My "Clean Code Toolkit": ESLint/Prettier configurations, custom Git hooks, and documented pattern libraries that ensure consistent, production-ready code
• Performance-First Mentality: Implementing Lighthouse optimizations, database query optimization, and server-side rendering strategies
• Real-Time Expertise: WebSockets, SSE implementations for live financial data, and notification systems
How I Work With You:
📅 Agile, But Adaptive
I don't just follow sprints—I tailor them. Whether it's daily micro-deliverables for urgent projects or weekly milestone-driven development, I adapt to your operational rhythm while maintaining transparent progress tracking.
🗣️ Communication That Closes Gaps
Regular technical translation sessions where I explain complex concepts in business terms, ensuring you're never in the dark about technical decisions that affect your product.
🔧 My Quality Guarantee:
Every line of code comes with:
Strategic commenting that explains the "why" behind complex logic
Performance benchmarks for critical operations
Security audit considerations built into the development process
A comprehensive handoff package including architecture diagrams and maintenance guides
Beyond Code:
I'm your technical thought partner. During our collaboration, you'll benefit from:
Proactive technology recommendations based on your specific growth trajectory
"Tech Debt Audits" for existing systems with clear ROI-focused improvement plans
Knowledge transfer sessions to empower your team for long-term success

$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.

Have you ever launched a blockchain project that looked great on paper but fell apart in production?
I've spent 8 years making sure that doesn't happen for token launches, DeFi protocols, NFT platforms, and everything in between.
𝗛𝗲𝗿𝗲'𝘀 𝘄𝗵𝗮𝘁 𝘁𝗵𝗮𝘁 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝗹𝗼𝗼𝗸𝘀 𝗹𝗶𝗸𝗲 𝗶𝗻 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲:
Delivered an ERC20 token that reached an $18M market cap.
Helped a blockchain startup close $10M in funding with audit-ready smart contracts.
Built a multi-chain NFT marketplace that generated $1M+ in sales.
These aren't team numbers. These are projects I was directly responsible for.
𝗪𝗵𝗮𝘁 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘀𝗮𝘆 𝗮𝗳𝘁𝗲𝗿 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗺𝗲:
"Delivered ahead of schedule and the contract logic was airtight - exactly what we needed before our raise."
"Came back for a second project. That says everything."
"Flagged a vulnerability our previous dev missed. Saved us from a serious exploit."
𝗪𝗵𝗼 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵:
I work with founders, CTOs, and product teams building serious blockchain infrastructure - not weekend side projects. If your project involves real capital, real users, or a real audit, that's where I'm most useful.
𝗗𝗲𝗙𝗶 𝗽𝗿𝗼𝘁𝗼𝗰𝗼𝗹𝘀: DEX platforms, staking systems, yield farming, token launchpads, cross-chain bridges
𝗧𝗼𝗸𝗲𝗻 𝗲𝗰𝗼𝘀𝘆𝘀𝘁𝗲𝗺𝘀: ERC20, BEP20, SPL tokens with custom tokenomics, vesting, and IDO/ICO structures
𝗡𝗙𝗧 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀: marketplaces, GameFi, dynamic NFTs, royalty systems, IPFS hosting
𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆:audit support, vulnerability assessment, gas optimization, test coverage with Hardhat and Foundry
𝗖𝗿𝘆𝗽𝘁𝗼 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻: MEV bots, arbitrage systems, Telegram trading bots, copy trading infrastructure
𝗙𝘂𝗹𝗹-𝘀𝘁𝗮𝗰𝗸 𝗱𝗔𝗽𝗽 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁: from Solidity or Rust contracts to React/Next.js frontend and Node.js/Python backend
𝗧𝗲𝗰𝗵 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 𝗱𝗮𝗶𝗹𝘆:
𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀: Solidity, Rust, Hardhat, Foundry, Truffle, Brownie, Anchor, OpenZeppelin
𝗖𝗵𝗮𝗶𝗻𝘀: Ethereum, Solana, Binance Smart Chain, Polygon, Avalanche, TRON
𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: React.js, Next.js, TypeScript
𝗕𝗮𝗰𝗸𝗲𝗻𝗱: Node.js, Python, PostgreSQL, MongoDB, MySQL
𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀: Web3.js, Ethers.js, MetaMask, WalletConnect, Infura, Alchemy, Chainlink, IPFS
𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 𝗜'𝘃𝗲 𝗯𝘂𝗶𝗹𝘁 𝗳𝗼𝗿:
DeFi & crypto infrastructure - protocols, exchanges, launchpads
NFT & GameFi - marketplaces, staking dApps, metaverse integrations
Blockchain fundraising - ICO/IDO platforms, investor-facing audit-ready contracts
Crypto trading & automation - bots, arbitrage systems, on-chain analytics
Enterprise blockchain - supply chain, real estate tokenization, identity systems
𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸:
I don't disappear after handing over code. Most of my clients come back for the next project and the one after that. I give daily or weekly updates depending on project scope, flag problems before they become blockers, and write contracts that your auditor won't send back with a list of critical findings.
𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻: Slack, Telegram, JIRA, Trello, GitHub - whatever your team already uses.
8 years. 3 major outcomes. 0 exploited contracts.
If that's the kind of developer you've been looking for, click Invite to Job or send me a message. I'll usually reply within a few hours.
