Hi, I am a full stack developer with over 6 years of experience building web applications from the ground up. I specialize in bridging the gap between complex backend logic and pixel-perfect design. While many developers focus on just one side of the stack, I enjoy ensuring that the code is as clean as the user interface. I’ve worked with frameworks like Next.js, React.js, Vue.js, Laravel, and Django to build fast and scalable applications. On the frontend, I focus on creating polished, responsive UIs using React, Tailwind CSS, Bootstrap, and JavaScript/jQuery Whether it is a custom dashboard or a high-performance web app, I make sure the final product matches your design exactly. I keep my process simple and transparent. I prioritize clear communication, organized code, and hitting deadlines. If you are looking for a developer who can handle the full architecture while maintaining a sharp eye for detail, I would love to help you build your project. I am looking forward to hearing from you. Cya!

Are you looking for a 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿 who actually gets things done? I'm Artem. I've been building web products for years — React, Next.js, Node.js, TypeScript — the full picture, frontend to backend. Not "I touched React once" kind of experience. Real production systems, real users, real scale. I built and scaled Yumzi.app to 10,000+ restaurants. That kind of thing. 𝗛𝗼𝘄 𝗜 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝘄𝗼𝗿𝗸: I don't wait around for someone to explain every detail. I jump into the codebase, understand the architecture, ask the right questions, and start moving. If something in the project doesn't make sense technically — I'll tell you honestly instead of just building it the wrong way. I care about the product, not just the ticket. So if I notice something broken or a better approach while working on your project — I'll bring it up. That's just how I operate. 𝗪𝗵𝗮𝘁 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵: 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: React, Next.js (App Router), TypeScript, Tailwind CSS, Shadcn/ui, Framer Motion, Redux, Zustand 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗮𝗻𝗱 𝗗𝗮𝘁𝗮: Node.js, NestJS, Prisma, PostgreSQL, Supabase, Firebase, REST/GraphQL 𝗔𝗜 𝗮𝗻𝗱 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀: OpenAI API, Claude, Grok, Stripe, DLocal, Twilio, SendGrid 𝗧𝗼𝗼𝗹𝘀: Git, Vercel, Docker, Figma to code I'm open to both — long-term product work where I become a core part of your team, or shorter engagements like MVPs, new features, or performance problems nobody else wants to debug. Send me a message, let's talk about your project.

Your mobile app deserves to actually ship and stay live, not get stuck in a perpetual beta or rebuilt from scratch a year after launch. I'm Asjad Raja, a Senior React Native Developer with 5+ years of experience building cross-platform mobile apps for iOS and Android. I work in both the React Native CLI and Expo workflows, so the toolchain gets picked based on your project's actual constraints native module needs, OTA update requirements, team size instead of a default. What that looks like in practice: native device integration through Expo-Camera and device APIs, location-based features built on Google Maps with custom markers and live data overlays, push and scheduled local notifications, offline-friendly state with AsyncStorage and Context API, and Firebase-backed auth, real-time data, and cloud storage when a lightweight backend is the right call. I've taken apps through the full lifecycle architecture, build, OTA updates, and App Store / Play Store submission including a location-based EV charging app that's live and publicly downloadable on both stores today. That's the level of finish I aim for: not a working build, a shipped product. Because I also work as a full-stack engineer (Next.js, Node.js, Express, MongoDB, PostgreSQL), if your mobile app needs a custom backend, an admin dashboard, or a web companion app, I can build that piece too without bringing in a second contractor and re-explaining your product from scratch. Where I've shipped real apps: health and nutrition tracking, family and productivity tools, location-based services, gamified consumer apps, and AI-assisted recommendation features layered into mobile UX. Clients across the US, EU, and AU keep coming back for strong async communication across time zones, early flags on platform-specific risks App Store review gotchas, native module conflicts before they become a fire drill, clean documentation, and a long-term partnership mindset, not a one-off task executor. If you've got a mobile app that needs to go from idea to App Store, or an existing app that needs rebuilding the right way, send me a quick overview and I'll map out the architecture, the Expo-vs-bare-RN call, and a realistic timeline. No fluff, no overselling.
