🏆 Senior Full-Stack AI Developer | React • Next.js • Node • AI | $200K+ Earned · 100% JSS Founders hire me when their MVP needs to ship in weeks - and still hold up past 100K users. I build AI-powered SaaS and mobile apps that real customers pay for. The kind of code your next developer won't have to rewrite. PROBLEMS I SOLVE Most founders come to me with one of these: ❌ No clear technical roadmap — every developer gives a different answer. ❌ An existing product that's slow, breaking, or impossible to maintain. ❌ A codebase from cheap developers — broken architecture, missed deadlines, technical debt blocking every new feature. ❌ Pressure to ship fast — but no trust left after being burned before. Here's why it keeps happening: most freelancers code feature by feature without thinking about what happens at month six. I don't. Every decision I make — stack, architecture, deployment — assumes your product will grow, your team will change, and the next developer will need to read what I wrote. 120+ shipped projects. 20+ countries. Zero rebuilds requested. ──────────────────────────────────────── WHAT YOU GET 🔷 A technical roadmap before a single line of code is written Every custom enterprise system starts with a plan. As a Full Stack Developer React specialist, I map out stack decisions, data models, and integrations first — whether it's a full stack developer React Node API, a full stack developer Supabase React platform, or a full stack developer React Firebase app. Projects without a plan cost 3x more to fix later. 🔷 A production-ready product, not a dressed-up prototype As a Full Stack Developer React Node developer, I build advanced B2B products ready to go live immediately. Rapid delivery without cutting corners — clean code, testing, CI/CD, deployment pipelines — everything needed to stay live under real load. 🔷 Frontend and UI/UX users actually enjoy As a react developer and web developer, I build fast, intuitive interfaces — CRM systems, dashboards, marketplaces with real-time updates, automation platforms, and SaaS products — as a full stack node.js react system where frontend and backend work as one. For API-driven products I work across react nodejs and react redux architectures. 🔷 Backend systems that don't break under pressure Node js with Express, Django and Flask for Python-heavy workloads, Stripe, and cloud infrastructure — built with proper auth, business logic, and integrations. As a python full stack developer I handle data pipelines, automation, and react js applications where performance matters. 🔷 AI features that add real product value As an AI-focused full stack engineer, I build AI-powered, AI-driven, AI-enhanced, and AI-focused features — agentic workflows, AI-assisted and AI-augmented interfaces, multi-agent systems with MCP, chatbot and chat experiences, and LLM integrations via OpenAI or Claude Code. If your SaaS needs to be AI-native, I know how to build that. 🔷 E-Commerce, CMS & broader stacks As a Full Stack Developer React, Shopify specialist, and wordpress developer, I build storefronts and platforms that convert. I've also worked across laravel vue, mern, ruby on rails, react next node supabase react native, and .net full stack developer codebases — adapting to what you have instead of forcing a rewrite. ──────────────────────────────────────── MY APPROACH 1. Discovery first — I act as your architect and partner before writing a single line. 2. Architecture before code — a plan you approve. No black boxes. 3. Rapid, iterative delivery — real progress every week. I'm a fast builder who doesn't cut corners. 4. Honest communication — you hear about problems from me first. 5. Built to hand off — clean, advanced code your team can work with. ──────────────────────────────────────── SDA COMPANY Behind this profile is SDA Company — a focused, senior software development team I founded. We're not hiring — we're selective. Over 5+ years we've helped clients raise funding, hit deadlines and scale to thousands of users. As CEO and lead specialist, I oversee every project directly. You get a founder with skin in the game, backed by a team that executes. ──────────────────────────────────────── 💡 Have a product to build or a platform to fix? Send me a message - no pitch. Just a real conversation.

I build and scale real production systems using Ruby on Rails, Node.js, Laravel, React, Next.js, MERN, PostgreSQL, MySQL, MongoDB, and AWS. Over fifteen years and more than thirty Upwork projects, I’ve delivered SaaS platforms, API architectures, e commerce systems, marketplace engines, cloud migrations, DevOps pipelines, and full stack applications that power real businesses, not prototypes. Rails apps struggling with performance. Node.js APIs breaking under traffic. Laravel backends falling apart during payment flows. React and Next.js front ends slowing down user activation. AWS setups missing DevOps structure. These are the systems I fix, redesign, and scale. I work as a system architect, not a “feature developer”. My experience spans Ruby on Rails, MERN stack, Node.js, Laravel, React, Next.js, AWS architecture, Docker, Kubernetes, CI/CD, and everything required to turn a fragile product into a stable, scalable platform. 🧠 𝐂𝐎𝐑𝐄 𝐄𝐍𝐆𝐈𝐍𝐄𝐄𝐑𝐈𝐍𝐆 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄 (𝐊𝐞𝐲𝐰𝐨𝐫𝐝 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐞𝐝) 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 React, Next.js, Vue, Node.js, Ruby on Rails, Laravel, MERN stack SPA architecture, component systems, REST APIs, GraphQL, micro front ends, modular monoliths, multi tenant SaaS.
