Full-Stack AI SaaS Developer building production B2B platforms where AI agents, Stripe billing, and multi-tenant architecture work together at scale. Top-Rated · $30K+ delivered · 5+ years building systems, founders scale without rebuilds — including a healthcare SaaS at 1,000+ patients with zero payment incidents. WHAT I BUILD End-to-end SaaS platforms — backend, frontend, AI agents, payments, infrastructure. Not a generalist who "also knows AI" or "also touches Stripe." A full-stack SaaS engineer whose AI and billing layers are the parts most teams underbuild. → Multi-tenant SaaS architecture with proper data isolation, RBAC, and tenant-aware billing → Subscription platforms with Stripe Billing — plans, proration, dunning, usage-based metering → Marketplace platforms with Stripe Connect — Standard, Express, and Custom accounts, deferred onboarding, split payouts → Production webhook infrastructure — idempotency, retries, dead-letter queues, signature verification → Authentication, authorization, customer portals, and admin dashboards → API design (REST + tRPC) with rate limiting, auth, and proper error handling AI IN PRODUCTION SAAS AI features are now expected in B2B SaaS. I build them as core capabilities, not bolt-ons: → Custom multi-LLM agents that complete multi-step workflows (onboarding, form processing, support automation) → OpenAI and Claude API integrations with cost controls, retry logic, observability, and fallback handling → Multi-model routing — the right LLM for each task (cheap models for classification, premium for reasoning) → Document-aware chat and RAG pipelines (pgvector), plus workflow assistants → Usage tracking and metered billing for AI features — the Stripe Billing + AI metering integration most teams ship broken I understand the business side of AI features — token costs, latency, fallbacks, prompt observability, and how to bill for AI usage correctly. PAYMENTS DEPTH The Stripe billing layer is where most AI SaaS products break quietly — subscriptions that don't update, metered events that go unreported, and webhook handlers that fail to process dispute events. I've shipped production payment systems across 7 gateways — Stripe (including Connect), PayPal, iXoPay, Dimoco, ACI Processing, emerchantpay, and PayBank2Bank. Real depth across subscription billing, usage-based metering, marketplace payouts, and webhook reliability. RECENT WORK → catalyst-payment-app (B2B SaaS) — Custom multi-LLM agent for payments onboarding automation. Multiple models are routed for adaptive multi-step form completion. Stripe Connect with deferred KYC and multi-gateway fallback. → Inoqare (HealthTech SaaS) — Architected from zero. Multi-tenant healthcare platform serving 1,000+ patients with subscription billing and zero payment incidents in production. → Multi-step payment flow optimization (Marketplace) — Custom checkout retention flow that lifted payment conversion by 35%. → Gateway integration optimization — Diagnosed integration issues silently dropping conversions. +20% lift, pure infrastructure work. → Real-time SaaS platforms — Twilio-based chat, voice, and custom invoicing with integrated billing. INDUSTRIES AI SaaS · B2B SaaS · HealthTech · FinTech · Marketplaces · Subscription platforms · Workflow automation STACK Backend: Node.js · NestJS · Express · TypeScript · PostgreSQL · MongoDB Frontend: Next.js · React · Tailwind · shadcn/ui AI: OpenAI API · Claude API · Multi-model agents · RAG / pgvector · LLM workflow integration · Prompt engineering Payments: Stripe (Connect, Billing, Tax) · PayPal · regional gateways Infrastructure: AWS · Vercel · Docker Real-time: Twilio · WebSockets HOW I WORK → Fixed price, fixed scope, fixed timeline — no surprise hourly bills → Daily async updates (Slack, Loom, written) — async-first, calls only when essential → Clean code with tests, docs, and deployment instructions → NDA from day one Whom I WORK WITH BEST → AI SaaS founders building agent-based or LLM-powered products → B2B SaaS adding AI features that need to be metered and billed → Marketplace founders needing Stripe Connect done right → Existing SaaS with AI integration, billing, or webhook pain → Agencies needing a white-label AI + SaaS + payments specialist If your project involves building an AI SaaS, integrating AI agents, shipping Stripe billing, or fixing payment infrastructure — send me a brief. I'll respond within 24 hours with a decision on whether it's a fit.

🏆 I led full stack developer work at Bairro, a startup that reached $25M valuation with $7M raised - serving 50K+ users on a React and Node.js platform I architected as lead full stack developer. That full stack developer experience shaped my approach as a website developer who delivers production-ready results. Over 7+ years as a full stack developer I have shipped 50+ projects across SaaS Platform, Web App, Mobile App, and AI-Powered products using React and Node.js. 🚀 As a Senior Full Stack Developer and Full Stack Engineer I cover the full product lifecycle. I started as a web developer and website developer before becoming a full stack developer who handles React frontend and Node.js backend equally well. My full stack developer react node experience means clients work with one Full Stack Web Developer instead of separate teams. Every full stack developer engagement I take begins with React and Node.js architecture planning and ends with a production-ready SaaS Platform or Web App. 👋 Hi! I am Oleksandr, a Full Stack Developer and website developer specializing in scalable SaaS Development and App Development. As a react developer with strong Node.js skills, I build apps where React handles complex UI logic and Node.js manages APIs and real-time services. My Full Stack Developer approach covers SaaS Web App, Marketplace App, MVP SaaS, and Platform Development projects. Whether you need a Developer Needed for a SaaS Product or a Full Stack SaaS Developer for a Management Platform — I deliver. 📱 My full stack developer background spans diverse ecosystems. I work as a full stack developer ai specialist and AI Engineer implementing machine learning and AI Agent features. I deliver full stack developer shopify specialist work, full stack developer laravel builds, python full stack developer projects, and .net full stack developer enterprise solutions. I use wordpress for CMS-driven website developer projects. As a mobile app developer and React Native specialist I build Mobile App Development products for iOS and Android. I also cover Real Estate and Property Management platforms as a full stack developer. 🌐 As a website developer I build everything from landing pages to enterprise platforms. My website developer work includes react next.js node.js backend developer solutions, word press website developer projects, wordpress developer and website design builds, and shopify website developer integrations. I handle wix website developer requests and follow SEO best practices on every website developer project. Every website developer solution uses React for speed and Node.js for backend power. ⚡ React is my primary framework as a Full Stack Developer and Full Stack Web Developer. React powers SaaS Dashboard, Marketplace App, and Management Platform products I build. I pair React with Node.js creating unified JavaScript stacks as a full stack node.js react specialist. React components communicate with Node.js APIs seamlessly in my full stack developer react workflow. Beyond React I use Vue, Angular, and react native for Mobile App Development — but React with Node.js stays my Full Stack Developer core. 🔧 Node.js is my primary backend as a back end developer and node.js backend developer. I build REST APIs, GraphQL, and microservices using Node.js in every Full Stack Developer project. My node.js react pattern handles heavy traffic for SaaS Platform and Web App clients. Node.js powers authentication, payments, real-time messaging, and AI Agent data pipelines in every full stack developer engagement. 📲 As a full stack mobile developer I deliver Mobile App Development using React Native and react native mobile builds. A Full Stack Developer react node architecture spans web and mobile — one Full Stack Developer handles the full App Development lifecycle. My react native work covers SaaS Product, Marketplace App, and Real Estate mobile platforms. 🔗 As a Full Stack Developer and web developer I integrate services across every website developer project. React frontends connect to CMS, e-commerce, and CRM solutions. Node.js services plug into Stripe, Twilio, and dozens of APIs. My website developer and Full Stack Developer solutions deliver production-ready SaaS Development results on time and on budget. ✅ Every website developer and Full Stack Developer project follows clean architecture. React stays modular, Node.js stays documented, deployments run automatically. React and Node.js together are the Full Stack Developer foundation I build on. I validate every Web App and SaaS Platform against real benchmarks. React. Node.js. Full Stack Developer. website developer. React. Node.js. full stack developer. React. Node.js. React.

⭐ Senior Full Stack Developer | 50+ Products Shipped ✉️ 𝗠𝗘𝗦𝗦𝗔𝗚𝗘 𝗠𝗘 I typically respond within 12 to 24 hours, and urgent projects can be prioritized. I lead a senior engineering team that builds, scales, and rescues complex web and mobile products. Whether you need a single Senior Full-Stack Engineer or a dedicated team that plugs in and ships from day one – we move fast and deliver production-grade results. Over 50+ completed projects, we've helped startups and scale-ups go from prototype to release, and stepped in as the core engineering team when products needed to grow. We work primarily with Node.js and Nest.js on the backend and React / Next.js on the frontend – the same stack that powers most modern, high-load SaaS platforms. 🎯 WHAT YOU GET WHEN YOU HIRE US – 100% completion rate – every project delivered, backed by a 100% Job Success Score across 6000+ hours on Upwork – Fast start & team scaling – we onboard in days, not weeks, and scale the team up or down as your roadmap demands – AI-accelerated delivery – we integrate AI tools into our development process to improve code quality and ship faster – Full cycle – from prototyping and UX to architecture, development, and release 🏆 RESULTS "I highly recommend Pavlo - he will be my goto next time for any work like this. He understood exactly what I needed and was really fast to act. One of the best freelancers Ive used on Upwork!" – Lauren B., Client "Pavlo and his team were highly responsive, professional, and extremely efficient in diagnosing issues and identifying the root causes of several problems in the codebase. Their debugging process was structured and precise, and their recommendations during the code review were very valuable in improving the overall stability, performance, and maintainability of our system." – Client, Product Manager, SaaS Platform SELECTED PROJECTS – CaJu AI – an enterprise AI platform with real-time AI workflows, scalable Node.js backend services, and React-based interfaces for compliance-focused customer support automation. – CookieFirst – a large SaaS platform where we became the core engineering team, scaling the product, expanding functionality, and improving performance. – Ragusa Express – a booking platform with online reservations, payments, backend modernization, and React frontend improvements. TECHNICAL STACK Backend: Node.js, Nest.js, Express.js, Laravel, Symfony (TypeScript, PHP, Python) Frontend: React, Next.js, Vue.js, Tailwind CSS, SCSS/Sass Mobile: React Native, Java, Kotlin, Swift Cloud & Tools: AWS, Docker, NGINX, Supabase, PostgreSQL, MongoDB, DevOps, Figma If you're looking for a reliable Senior Full Stack partner who works in Node.js, Nest.js, and React and can take ownership from idea to launch – send me a message and tell me about your project. ENGAGEMENT MODELS You can bring on a single Full Stack Developer for focused feature work, a dedicated Backend Developer to own your Node.js services, or a full pod combining Full Stack Developer and Backend Developer roles with a React specialist on top. Most clients start with one Full Stack Developer or one Backend Developer and scale up once trust is established – we've grown from a single Node.js Backend Developer to an eight-person team on more than one long-term engagement. WHY NODE.JS AND REACT We standardized on Node.js and React because they let a single Full Stack Developer move across the stack without context-switching, and they give a Backend Developer and a React engineer a shared language when APIs and UI need to evolve together. A Node.js Backend Developer on our team typically ships REST or GraphQL services that a React frontend consumes within the same sprint, which is the main reason clients hire a Full Stack Developer from us instead of stitching together separate backend and frontend contractors. A FEW THINGS CLIENTS ASK BEFORE HIRING Can I hire just one Backend Developer? Yes – many engagements start with a single Backend Developer handling Node.js architecture while we hold a Full Stack Developer in reserve for later. Do you offer a trial period? Yes, a short paid trial with one Full Stack Developer or Backend Developer is the easiest way to check fit before scaling the team. Can you work backend-only? Yes – some clients only need a Node.js Backend Developer, others need a full Full Stack Developer team covering React end to end. Whether you need a Full Stack Developer or a Backend Developer, message me with your stack and timeline and I'll match you with the right Full Stack Developer from the team within 24–48 hours. Best regards, Pavlo Jedi at Red Carlos Solutions

Your last developer ghosted you. The one before that delivered spaghetti code you're still paying someone to fix. And now you're scrolling through 200 profiles that all say the same thing: "I am a passionate full stack developer with 6+ years of experience." Stop. Read this instead. Here's what I've done recently: → Built an AI-powered wellness platform — zero to 500+ users in 3 weeks. Sentiment analysis, recommendation engine, intelligent chatbot. My client called the quality "exceptional" and me "a true partner." → Shipped a multi-tenant AI marketplace with LangChain automation for a US-based startup. The CTO called me "a highly skilled AI Senior Engineer." → Built a healthcare staffing platform with nurse registration, compliance tracking, client dashboards, and Stripe payments. The founder said he "had no clue how complicated it would be" — I handled everything. What I build: → AI-powered SaaS from architecture to production → LLM systems — chatbots with memory, RAG pipelines, AI agents that actually work → Stripe-integrated platforms — subscriptions, Connect, marketplace payment splits → Multi-tenant apps with RBAC, admin panels, and clean APIs → MVPs that don't look or feel like MVPs I am NOT the right developer for you if: ⛔ You're shopping for the cheapest rate on the platform ⛔ You want 15 revisions because you don't have a clear vision ⛔ You think "MVP" means broken and ugly ⛔ You've already burned through 3 developers and blame all of them I AM the right developer if: ✅ You're a founder or product owner with a real vision. ✅ You want one person who owns your entire product — frontend, backend, AI, infra, deployment ✅ You're tired of explaining the same thing to developers who still don't get it ✅ You want to launch in weeks, not months — without accumulating technical debt that kills you later Here's how this works: you message me with what you're building, your timeline, and your budget. I'll review it. If I can deliver something great, I'll respond within 4 hours with a clear plan. If I can't, I'll tell you why and point you in the right direction. I don't pitch. I don't beg. I build.
