🏆 Senior Full-Stack AI Developer | React • Next.js • Node • React Native | $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. 🔷 Mobile apps across both platforms from one codebase As a react native developer and mobile app developer, I've delivered 30+ apps that feel native and perform well. For projects where Flutter fits better, I work with that too. My react node react native approach keeps mobile and web in sync without doubling the cost. 🔷 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. Stack: React / React.js, Next.js, React Native, Node.js, Python, Django, .NET, Laravel, Supabase, Firebase, PostgreSQL, MongoDB, Shopify, WordPress, MERN, GraphQL, Stripe, AWS, Docker, Flutter

I build AI features that ship inside real products, not demos. Three are live right now: PoweredByHue (AI-curated shoppable UGC), RealReports.ai (AI property intelligence across the US), and MaxHome.ai. Senior engineer, 20 years across AI, data engineering, full-stack, cloud, and security. Most of my work sits where those overlap: an LLM or RAG system that needs clean data behind it and a real app in front of it. AI engineering. LLM and RAG systems wired into apps people actually use. LangChain, LangGraph, OpenAI, and vector databases (Pinecone, Weaviate, Chroma). I handle the full path: retrieval, embeddings, context handling, and the app it lives in, so the feature is reliable instead of a clever one-off. Data engineering. The pipelines that feed those systems. ETL/ELT on AWS, Azure, and GCP with Snowflake, dbt, Airflow, and Power BI. I have migrated legacy SQL Server and SAP BW into a hybrid Snowflake-Azure platform and built cross-cloud pipelines for real-time analytics. Full-stack and DevOps. React, Angular, Vue, and Next.js on the front; Node, FastAPI, .NET, and Spring on the back. Docker, Terraform, CI/CD, and Kubernetes to ship it and keep it running. Background that shows up in the work: First Responder at AWS, Production System Engineer at ByteDance, and Application Security Analyst at RedShield. So the systems I build are reliable and secure by default, not just functional. How I work: I give you ranges, not guesses. I flag risks early. I start with the simplest thing that works and add only what the project needs. If you have an AI build, or a data pipeline that needs to feed one, send me the details and I will tell you exactly how I would approach it. #FullStack #SoftwareEngineer #CloudArchitect # DevOps # BackendDeveloper #FrontendDeveloper #SystemArchitecture #Microservices #CloudComputing #EnterpriseSoftware #ReactJS #VueJS #QuasarFramework #JavaScript #TypeScript #HTML #CSS #SASS #LESS #TailwindCSS #Bootstrap #MaterialUI #NodeJS #PythonFlask #JavaSpring #Go #Golang #Ruby #RESTAPI #GraphQL #MySQL #PostgreSQL #MongoDB #Redis #Kafka #Docker #LXC #VMware #VirtualBox #CI_CD #Kubernetes #Terraform #Ansible #Serverless #Nginx #Apache #Git #Gradle #Maven #Jira #Trello #Webpack #Vite #Babel #ESLint #Prettier #Storybook #Jest #Mocha #Cypress #Playwright #NextJS #NuxtJS #GatsbyJS #ExpressJS #FastAPI #SpringBoot #ApolloGraphQL #Prisma #TypeORM #Sequelize #Postman #Swagger #OpenAPI #SocketIO #WebSockets #RESTfulAPI #ProgressiveWebApps #PWA #SSR #SSG #CSR # WebPerformance #CodeSplitting #LazyLoading #CachingStrategies #ResponsiveDesign #CrossBrowserCompatibility #Accessibility #SEO #HeadlessCMS #Contentful #Strapi #SanityCMS #CloudFunctions #AWSLambda #AzureFunctions #GoogleCloudFunctions #CI_CD_Pipelines #DockerCompose #K8sDeployment #RedisCaching #MessageQueues #ElasticSearch #Algolia #Sentry #NewRelic #Datadog #Monitoring #Logging #ErrorTracking
