I take a project from the first screen to a running product - frontend, backend, database, payments and deployment. One developer, one bill, no gaps between the pieces. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I BUILD ▸ Web applications (MERN stack, Next.js, Vue.js) ▸ Mobile apps for iOS and Android (React Native, Expo) ▸ SaaS platforms and MVPs for startups ▸ Admin dashboards and CRM systems ▸ REST APIs and GraphQL APIs ▸ Real-time apps - chat, live tracking, notifications (WebSockets) ▸ Login systems and role-based access (JWT, OAuth) ▸ Stripe and PayPal payment integration ▸ Fixing and finishing projects another developer left broken ━━━━━━━━━━━━━━━━━━━━━━━━━━━ MY STACK Frontend: React.js, Next.js, Vue.js, JavaScript, TypeScript, Redux, Tailwind CSS Backend: Node.js, Express.js, NestJS, REST API, GraphQL Mobile: React Native, Expo Database: MongoDB, PostgreSQL, MySQL, Firebase Cloud: AWS, Docker, Vercel, Git, CI/CD ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT THAT LOOKS LIKE IN PRACTICE ▸ Dashboards that stay fast after the data grows, because the queries were planned before the UI was ▸ Payment flows that handle failed cards, refunds and edge cases - not just the happy path ▸ Mobile apps that clear App Store and Play Store review, not left sitting in rejection loops ▸ APIs documented properly, so your next developer is not reverse-engineering my work ▸ Old codebases cleaned up and moved forward instead of thrown away ━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK ▸ I ask questions before I write code. Wrong assumptions cost you more than wrong syntax. ▸ You see progress while I build, not one big reveal at the end. ▸ Clean, structured code any developer can pick up later. ▸ If a feature will cost more than it is worth, I tell you before we start - not after the invoice. ▸ I stay available after launch for fixes and small changes. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET FROM ME ▸ A clear scope and timeline before any money moves ▸ Working code you can test throughout the project, not just at the end ▸ Full source code, database and deployment access - all of it is yours ▸ Written handover notes so you are never locked to me ▸ 30 days of free bug fixes after delivery ━━━━━━━━━━━━━━━━━━━━━━━━━━━ ABOUT ME 7+ years as a full stack developer, including years inside multinational companies where the code had to hold up under real users and real deadlines. I have also built and launched my own product from zero, so I already know where these projects usually break. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ Send me a message with what you are building. I will tell you straight if I am the right fit, what it will take, and what I would do differently. If I am not the right person for it, I will say so. 𝗙𝗿𝗲𝗲 𝟯𝟬 𝗺𝗶𝗻𝘂𝘁𝗲 𝗰𝗮𝗹𝗹.
