🎯 I build the custom web app your company runs on, plus the offline first app your field crew uses. One system, not 5 tools. ✔️ Laravel, Django, Next.js, React Native. 6+ years, and one client's revenue grew 140% past 5M a year. You bought a tool, then a second for what it missed, then a third for the part neither did. Now 6 subscriptions each do 60% of the job and somebody retypes between them every Monday. Or an AI tool built your app, and it demos beautifully and falls over when real users arrive. 𝗧𝗛𝗘 𝗢𝗙𝗙𝗜𝗖𝗘 𝗦𝗬𝗦𝗧𝗘𝗠 𝗔𝗡𝗗 𝗧𝗛𝗘 𝗖𝗥𝗘𝗪'𝗦 𝗔𝗣𝗣 𝗔𝗥𝗘 𝗢𝗡𝗘 𝗕𝗨𝗜𝗟𝗗 The market sells these separately. A CRM vendor for the office, a field app vendor for the trucks, and a bill to make them talk. I build them as one thing on one database. A dispatcher schedules a job and it's already on the tech's phone. The tech closes it out in a crawlspace with no bars, and the photos, signature, parts used, and time on site land in the office the second that phone finds a tower. Nobody retypes anything. 𝗪𝗛𝗔𝗧 𝗜 𝗚𝗘𝗧 𝗛𝗜𝗥𝗘𝗗 𝗙𝗢𝗥 ✔️ Internal Operations Platforms and Custom CRM Your pipeline stages, your fields, your roles. Quoting, dispatch, job history, invoicing, client portals, and your data migrated off whatever you're leaving. ✔️ Offline First Field and Mobile Apps React Native or Flutter. Built so a tech with 0 bars still gets the job done, with the job list, checklists, photos, signatures, and time on site queued on the device and synced the moment signal returns. ✔️ Custom Web Applications in Laravel, Django, and Next.js Schema, backend, frontend, deploy, and the code in your repo when it's done. Multi tenant if you're selling it, single tenant if you're running it, decided before the schema exists. ✔️ Lovable, Replit, and Bolt Apps Finished to Production I take over the code instead of restarting it. Right now that's an AI tattoo design app built in Lovable. The demo works. Then auth, real data writes, and error handling turn out to be missing, and the model keeps rewriting the same file. 𝗪𝗛𝗔𝗧 𝗬𝗢𝗨'𝗥𝗘 𝗔𝗖𝗧𝗨𝗔𝗟𝗟𝗬 𝗛𝗜𝗥𝗜𝗡𝗚 🎯 One person across backend, frontend, mobile, and infrastructure. Nothing falls into the gap between contractors. 💡 A straight read on whether you need custom software at all. Sometimes it's a 2 week fix. ⚡ Claude Code and Cursor run across my stack daily, Laravel migrations to React components to Terraform. A build here costs a fraction of the agency quote. 𝗧𝗛𝗥𝗘𝗘 𝗖𝗢𝗠𝗣𝗔𝗡𝗜𝗘𝗦, 𝗧𝗛𝗥𝗘𝗘 𝗡𝗨𝗠𝗕𝗘𝗥𝗦 🏆 An HVAC Contractor Whose Office and Trucks Never Agreed Quoting in one file, dispatch in another, job history in a third. Built them a custom CRM, a field service tool, and a design tool as one system. → Result: revenue grew 140% and passed 5M USD a year after it went live. 🏆 An Ecommerce Operation Running on Sheets and n8n ShipStation orders moved through a Google Sheet and an n8n chain that failed quietly. One Laravel and React app replaced all of it. → Result: about 12 hours a week of manual order work gone. The business passed 1M USD a year. 🏆 A US Healthcare Company With Nothing on a Phone A weight loss app, then a booking, consultation, and telehealth app. Both React Native. → Result: 120k+ downloads and 2000+ virtual consultations a month. I spent 3 years before this as the IT support technician for a city government in Belo Horizonte. I was who people called when their system broke. The software people hate isn't ugly software.

🏆 7 years as a full stack developer. 50+ React and Node.js products shipped. 1 startup taken to a $25M valuation with $7M raised - Bairro, where I was lead full stack developer and website developer on a React and Node.js platform now used by 50K+ people. That is the track record behind every React and Node.js build I take on. 🚀 30+ SaaS Platform and Web App launches as a Senior Full Stack Developer and Full Stack Engineer. I started as a web developer and website developer before becoming a full stack developer who owns React frontend and Node.js backend equally. My full stack developer react node approach means one Full Stack Web Developer instead of three contractors - 40% faster delivery. 👋 Hi! I am Oleksandr, a Full Stack Developer and website developer with 7 years in React and Node.js. As a react developer I build interfaces in React and react typescript; as a Node.js specialist I run APIs and real-time services. My Full Stack Developer work covers SaaS Web App, Marketplace App, MVP SaaS, and Platform Development. Whether you have a Developer Needed post for a SaaS Product or need a Full Stack SaaS Developer for a Management Platform - I deliver. 📱 20+ industries as a full stack developer. I work as a full stack developer ai specialist and AI Engineer shipping AI Agent features. I deliver full stack developer shopify work, full stack developer laravel builds, python full stack developer projects, and .net full stack developer solutions. As a mobile app developer and React Native specialist I ship Mobile App Development for iOS and Android, including 12+ Real Estate and Property Management platforms. 🌐 100+ website developer projects delivered. My website developer work spans react nextjs and node.js backend developer builds, word press website developer projects, wordpress developer and website design work, shopify website developer stores, hubspot website developer setups, and wix website developer requests. Every website developer project follows SEO best practices with React speed and Node.js power. ⚡ React is in 100% of my full stack developer projects. React powers the SaaS Dashboard, Marketplace App, and Management Platform products I ship. I pair React with Node.js as a full stack node.js react specialist so components talk to APIs cleanly in every full stack developer react workflow. I also use vue, angular, javascript, flutter node.js, and react native for Mobile App Development - but React with Node.js stays my Full Stack Developer core. 🔧 Node.js handles 5M+ monthly requests across my client systems. As a back end developer node.js is my default for REST APIs, GraphQL, and microservices in every Full Stack Developer project. My node.js react pattern carries heavy traffic for SaaS Platform and Web App clients. Node.js runs authentication, payments, real-time messaging, and AI Agent pipelines in every full stack developer engagement. 📲 15+ mobile products as a full stack mobile developer. I build Mobile App Development with React Native, react native mobile, and react native expo. A Full Stack Developer react node architecture spans web and mobile, so one Full Stack Developer owns the whole App Development lifecycle. My react native work covers SaaS Product, Marketplace App, and Real Estate platforms. 🔗 50+ integrations as a Full Stack Developer and web developer. React frontends connect to CMS, e-commerce, and CRM systems. Node.js services plug into Stripe, Twilio, and dozens of APIs. My website developer and Full Stack Developer builds ship SaaS Development results on time. ✅ 0 abandoned projects in 7 years. Every website developer and Full Stack Developer build follows clean architecture: React stays modular, Node.js stays documented, deployments run automatically. React and Node.js are the Full Stack Developer foundation I build on, and I benchmark every Web App and SaaS Platform before handoff. 🔑 Why this full stack developer? A website developer who only knows React ships half a product; a Node.js engineer who never touches the frontend ships the other half. A full stack developer closes that gap. React without Node.js is a demo. Node.js without React is an API nobody sees. A full stack developer ties both together, and a good website developer keeps the result usable. 📌 Hire a full stack developer who writes React like a frontend specialist and Node.js like a backend one - and a website developer who does not disappear at handoff. My React code is documented, my Node.js services are tested, and every full stack developer project I close is a product you can run. That is what 7 years in React and Node.js buys you. 💬 Send me your brief. If it needs React, Node.js, a website developer, or a full stack developer who can own the whole build - let's talk. Every React and Node.js estimate I give is one I stand behind as your full stack developer.

I build automation systems that connect the tools a business already runs into a single workflow. AI agents, voice agents, video generation, CRMs, APIs, databases, MCP servers, and whatever else the stack requires, wired into pipelines that handle daily operations without anyone touching them. The complex builds are where I work best. A customer action in one system triggering enrichment in another, that data scoring a lead, the score routing outreach, the outreach writing back to a dashboard. Error handling at every step so it does not fail silently at 2am. If your automation needs more than two tools and real business logic, that is the job I want. I also build the software around the workflows. Using Claude Code, Codex, and Antigravity I ship internal dashboards, backend systems, research pipelines, and B2B SaaS tools. That includes the AI engineering underneath: RAG, agent orchestration, evaluation, and cost control. Built to stay reliable as the business grows, not just to demo well. 200+ automation systems delivered. 4 years building in production. Clients typically recover 30+ hours of manual work per week.

I build and deploy AI systems that combine RAG pipelines, multimodal agents and cloud automation into one scalable platform. My focus is turning advanced AI workflows into production ready systems with clear architecture, observability and strong DevOps practice. I work across LangChain, FastAPI, Redis and vector databases for retrieval and context management, using Docker, Terraform and GitHub Actions for CI/CD and infrastructure control. I design agents that process text, vision and speech together to automate complex reasoning tasks. Each system I create includes versioning, monitoring and secure deployments across GCP or AWS. If you need an engineer who can build complete RAG and multimodal agent platforms with reliable DevOps and MLOps integration, I can deliver it end to end.

I've rebuilt more automations than I've built from scratch — usually to replace twelve Make modules doing the job one clean workflow could do. That's the pattern I keep running into: businesses patch tools together until the whole thing breaks under real traffic. I build the version that doesn't break. I design AI automation systems on Make, n8n, and GoHighLevel that connect chatbots — ManyChat, Voiceflow, SendPulse — with Claude and GPT-4 to qualify leads, route them into HubSpot or Airtable, and close the loop without anyone manually copying data at 2 AM. Some of what that's looked like recently: a Telegram bot that logs expenses from a plain-language message straight into Google Sheets. An Instagram funnel that turned keyword replies into booked consultations. A signup flow that handled 200+ registrations for an online event with zero manual steps. What I actually deliver: AI agents that handle support and lead qualification around the clock, chatbot funnels that respond before a lead goes cold, and CRM setups where new contacts flow in and follow-ups fire without anyone touching a keyboard. Every AI automation system is built around your specific workflow, not a generic template. Stack: Make, n8n, GoHighLevel, ManyChat, Voiceflow, Claude API, OpenAI API, Airtable, HubSpot, Notion, Google Sheets. If your team is still copy-pasting between tools or typing out the same answers by hand — tell me what's breaking, I'll take a look.
