I’ve gone from building roads to building high-converting eCommerce brands. My own store, Versatile Desk, ranked #1 on Google and sold in 60+ countries. After realizing my passion was in design and development, I pivoted full-time into building, scaling, and optimizing Shopify stores. Today, I lead a full-service Shopify agency that works Monday–Saturday, 8AM–6PM EST, offering custom themes, app dev, UX design, and eCom consulting. Let’s hop on a call to plan how we’ll make your Shopify store work smarter—and look better—than ever.

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.

I help founders, SaaS teams, and business owners turn AI ideas into clear product, architecture, and implementation plans. If you are planning an AI chatbot, RAG system, AI agent, AI copilot, OpenAI/Claude/Gemini integration, or AI-enabled SaaS feature, I can help you decide what to build, what to avoid, and how to move toward a production-ready solution. I have 15+ years of experience across software architecture, SaaS development, API integration, cloud systems, and product delivery. I usually work with clients before or during development to bring clarity around the right AI approach, MVP scope, architecture, timeline, risks, and execution plan. I can help with: - AI integration strategy for SaaS products and web applications - RAG architecture for document, knowledge base, and internal search systems - AI chatbot, AI assistant, and AI copilot planning - AI agent and multi-agent workflow design - OpenAI, Claude, Gemini, Cursor, LangChain, and LlamaIndex solution planning - AI-powered document processing, summarization, search, and reporting - SaaS architecture, API integration planning, and cloud readiness review - AI MVP scoping, technical roadmap, and development team guidance Clients usually come to me when they need answers to questions like: 1. Can AI actually solve this product or business problem? 2. Should this be a chatbot, RAG system, AI agent, copilot, or simpler AI feature? 3. How do we connect AI with our SaaS product, database, CRM, internal tools, or APIs? 4. How do we reduce hallucinations and unreliable AI responses? 5. What should be included in the first MVP? 6. What will it take to build this securely, scalably, and cost-effectively? My focus is not “adding AI” just because it sounds good. My focus is helping clients build AI features that solve real product, workflow, and business problems. Relevant areas I can help plan: 1) AI Integration for SaaS Products - AI search, AI assistants, AI copilots, automated summaries, smart recommendations, document analysis, reporting workflows, and backend AI features for SaaS products and internal platforms. 2) RAG Systems and Knowledge Assistants - RAG architecture for products that need to answer from documents, PDFs, websites, customer records, internal knowledge bases, or structured business data. 3) AI Chatbots and AI Agents - Planning chatbot and agent workflows with conversation flow, role-based access, admin controls, escalation logic, backend integration, API actions, and human review where needed. Tools and technologies I work around include OpenAI, ChatGPT, Claude, Gemini, LangChain, LlamaIndex, RAG, vector databases, Pinecone, Weaviate, Chroma, Supabase, Python, FastAPI, Django, Node.js, React, Next.js, REST APIs, SaaS architecture, AWS, Azure, Google Cloud, API integrations, CRM/ERP integrations, n8n, Make, and Zapier-style automation. I bring both technical and business understanding. I can work with founders, product owners, CTOs, business teams, and developers to convert an idea into a clear technical direction. When needed, I can also support execution through Citrusbug/Aitiate’s AI and SaaS engineering team.

C++ / Qt engineer, 20+ years. I build the software that runs machines and instruments: embedded Linux firmware, Qt/QML operator HMIs, and the cross-platform desktop workbench engineers use to configure, calibrate and log. RECENT WORK - HPLC syringe pump - control software for an analytical laboratory instrument. - Firmware, control suite and workbench for the Multistage cable-stripping machine. - ScanScore / Forte / Bandora - 8 years on cross-platform music-notation software in Qt: optical score recognition, MIDI, PDF export. - Debian POS server - multithreaded C++ service, PostgreSQL, ESC/POS thermal printing, deployed onsite. 18,000 hours on Upwork at 100% Job Success, Top Rated Plus. WHAT YOU GET I lead a small Lviv team - firmware, HMI and desktop under one contract - and I stay hands-on in C++/Qt myself. You talk to me, not to an account manager. - Embedded & HMI: STM32, Arduino, embedded Linux, Qt/QML touch panels, industrial operator screens. - Desktop: cross-platform Qt for Linux and Windows; C#/.NET (WPF, WinForms, DevExpress) when the Windows side needs it. - Data: PostgreSQL, MS SQL, multithreaded C++ services, reporting, printing, installers. HOW I RUN PROJECTS - YOU SEE EVERYTHING Offshore teams fail on visibility, not on code. The process is built to remove that risk: - Private Jira server - you get an account and watch the board in real time. - Every code change is linked to its Jira task. Nothing lands untracked. - Code lives on our BitBucket Git server; you get access. - Every reported developer hour carries the developer's own comment explaining it. - Weekly and monthly reports, generated - not improvised. - A working demo build every week. You judge progress by running it, not by reading a status update. Scope is agreed as Work / Time / Budget with defined milestones before anything starts. Background: SoftServe 2002-2008, developer to tech lead; then my own team since 2014. ALSO AVAILABLE: legacy Windows rescue - MFC, Win32, COM/ATL, Visual C++ 6.0, WinForms/.NET. The desktop applications other developers won't touch. I have been maintaining and modernizing them since 2002. Send me the machine, the instrument or the old application - I will tell you honestly whether we are the right fit.
