👋 Hi, I’m a 🚀 🚀 🚀 🥇Top Rated Plus Full-Stack Developer 🚀 🚀 🚀 with over 17 years of hands-on experience building powerful, user-friendly web and mobile applications — from idea to launch and beyond. I’ve successfully completed 🔥 20+ long-term projects 🔥🔥🔥 on Upwork, partnering with clients from around the world to deliver solutions that are not only technically sound but aligned with real business goals. Whether you’re a startup looking for an MVP, or an established company needing to scale and refactor a legacy system — I’m here to help make it happen, smoothly and efficiently. 🚀 What I Specialize In 💻 Web Development From elegant interfaces to rock-solid server logic — I cover the full web stack. 🎨 Frontend: React, Next.js, Redux, Hooks, TypeScript, Tailwind, Bootstrap 🧠 Backend: PHP, Node, ASP.NET MVC (C#), Java Spring Boot, REST APIs 🗄️ Databases: MySQL, PostgreSQL, MSSQL, NoSQL 🧱 Clean architecture, reusable components, and scalable codebases 📱 Mobile Development Creating smooth, responsive apps that work beautifully on every device. ⚛️ Cross-platform: React Native (iOS & Android) 🍎 Native iOS: Swift, Objective-C 🤖 Native Android: Java, Kotlin 🛠️ Focused on great UX, offline features, and performance 🧩 Zoho Development Tailoring business solutions that work the way you do. ⚙️ Zoho CRM: Custom workflows, functions, automations 🛠️ Zoho Creator: Internal tools and app development 🧰 Tools & Technologies I Work With I’m comfortable across the entire stack — from frontend animations to backend architecture — and I love learning new tools when the job calls for it. Here's what I work with regularly: 🎨 Frontend & UI ⚛️ React, Next.js, React Native, Redux, Hooks, Context API 🧠 TypeScript, JavaScript (ES6+), JSX 💅 Tailwind CSS, MUI, Styled Components, Bootstrap, Sass 🧱 HTML5, CSS3, Responsive Design, Cross-browser compatibility 🌍 Internationalization (i18n), Accessibility (a11y), Lazy loading, Code splitting 🔧 Backend & Server-Side 💻 PHP (Laravel, Symfony), ASP.NET MVC (C#), Java (Spring Boot), Node.js 🛠️ RESTful APIs, GraphQL, WebSockets, OAuth2, JWT 📦 Microservices, Monolithic apps, Serverless functions 🧱 Clean Architecture, SOLID principles, Domain-Driven Design 🗄️ Databases & Storage 🐬 MySQL, PostgreSQL, MSSQL 🧪 MongoDB, Firebase, Redis, Realm 🧾 ORM tools: Entity Framework, Hibernate, NHibernate 🔍 Query optimization, indexing, schema design 🛠️ DevOps & Tools 🐳 Docker, Docker Compose, Git, GitHub/GitLab, CI/CD pipelines ☁️ AWS (EC2, S3, Lambda), Firebase, DigitalOcean 📊 Monitoring & Logs: LogRocket, Sentry, New Relic 🧪 Unit Testing, Integration Testing, Jest, Mocha, JUnit, NUnit 🧩 Zoho & Business Automation ⚙️ Zoho CRM: custom modules, deluge scripting, automation 🛠️ Zoho Creator: internal business apps, dashboards, logic flows 📊 Zoho Reports, Workflows, Integrations with external systems 📱 Mobile Development 📱 React Native (iOS/Android hybrid apps) 🍏 Native iOS: Swift, Objective-C 🤖 Native Android: Java 🎯 App Store & Google Play deployment, OTA updates, deep linking 🧠 Other Tools I Use Often 🗺️ Google Maps API, Chart.js, D3.js, Moment.js 🧩 Smarty, Handlebars, Sencha/ExtJS 🔄 JSON, XML, CSV, third-party API integration 🧪 Postman, Swagger, Figma (dev handoff), Trello, Jira, Slack 🌐 Cross-platform testing tools & responsive UI debugging Here’s what it’s like working with me: 🧩 I figure things out. Fast. From legacy spaghetti code to shiny new stacks — I dive in, untangle, optimize, and deliver. 📢 I communicate like a human. You’ll never get vague tech talk from me. I keep you in the loop, explain the "why" behind choices, and always deliver with clarity. 🛠️ Full-stack is my comfort zone. Whether I’m building snappy UIs or crafting efficient backends, I move comfortably across the stack — and make it all work together like a dream. 💡 I care about what we’re building. Your goals are my goals. I’ll offer ideas, challenge assumptions, and help make smarter decisions (not just code what’s asked). 🤹 I’m independent but team-friendly. I play well with others, but I’m also happy to take full ownership when needed and just get things done. 🔄 Always learning, never stuck. New tools, new frameworks, weird edge cases — bring it on. Long story short: I love building things that are useful, clean, scalable, and even a little fun. If you're looking for a dev who’s reliable, thoughtful, and maybe even a little witty — let’s connect! 📅 𝗕𝗼𝗼𝗸 𝗮 𝗽𝗮𝗶𝗱 𝗰𝗼𝗻𝘀𝘂𝗹𝘁𝗮𝘁𝗶𝗼𝗻 if you need specific advice or want to talk through a tech decision. 📩 Or just send me a message for a no-cost, no-pressure chat about your project — always happy to explore ideas!
