    🎯 I am an experienced Lead Software Developer (Django, Python, Flask, React.js and Vue.js developer, PHP Laravel Developer and DevOps engineer) with 14 years of experience in these fields. I have a long range of successful projects. I am also leading a web development team, Join.To.IT from Kyiv, Ukraine as co-founder and CTO. We have multiple React Native, Laravel (PHP), React.js, Vue.js, Node.js (Javascript), Go (Golang), React Native, Django, Flask (Python) developers. We are proven professionals in these areas. 🎯 🦾 Our team has already worked in such industries as: ✔️ Finance ✔️ Social media ✔️ Sport ✔️ ChatGPT integration ✔️ Legal ✔️ Sales ✔️ Automotive ✔️ Healthcare ✔️ Education ✔️ Manufacturing 🎯 Stack of technologies: ➕ PHP 7(Laravel); ➕ Go (Golang); ➕ PWA (Progressive Web Application); ➕ React Native; ➕ React.js (Saga, Thunk, Next.js, SPA); ➕ Node.js; ➕ Vue.js; ➕ VueX; ➕ Vue Router; ➕ Nuxt.js; ➕ Express.js; ➕ Django (Python); ➕ Flask (Python); ➕ SQL; ➕ PostgreSQL; ➕ MySQL; ➕ MongoDB; ➕ HTML/CSS; ➕ Bootstrap; ➕ Material-UI; ➕ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google maps and other maps, Facebook, Twitter, Instagram, Hellosign etc.); ➕ API development (PHP - Laravel, Node.js, Firebase, Python (Django, Flask, Celery). ➕ Ant Design; ➕ Adonis.js; This stack lets you make website development with frontend design alongside with backend programming. 📈 These services we provide with a discount: ✔️ wire-framing and business analysis; ✔️ dedicated Project Manager; ✔️ QA of front-end; ✔️ QA of API Postman or Swagger collections; ✔️ 3 months of support; ✔️ 6 months of warranty and debugging. In our work of website development and mobile applications development we go fully Agile. We are using a mix of SCRUM and Kanban methodologies. We also invite you to our systems of project management. We are using Trello for project management, but will be good to work with as suggested by Asana or Jira. We also will be happy to work on your custom solution. Bug tracking we do through Redmine. In all ways we try to make our Laravel and React Native development as transparent as possible. We also are great experts in building systems for business like CRM or ERP. We have great expertise in using Laravel for backend and Vue.js for frontend or React.js as a second option. For React.js, Vue.js projects we do an API. This technology helps to make them work faster. For mobile applications development we use React Native framework, as the most popular and fast growing solution for hybrid applications, which makes them native or even better to some researchers. For mobile app backend we use Laravel, Firebase, Node.js, Python. In some projects it will be better to use Python on the backend with the Django, Flask frameworks. In some cases we also use Node.js, Express.js as a progressive technology for backend. All our development we do through a secure approach. For bigger projects we place projects on different instances and servers. It secures all the source code, because it will be necessary to break security of more than one server. When we develop we also use a staging server. So for example projects in Laravel we will deploy on your-live-server, but during development we will push our code to your-staging-server, which will secure from spoiling a working code, in case it was deployed with issues. We are also working with Envoyer, Vagrant, CloudFlare, Docker, PullRequests on Git etc. Our team will do all this work in the most possible terms with high quality. Our QA department does different types of testing and checks projects for issues and bugs. We are a very responsive team: - our guys work hard and are office based - we do daily report in written or call format - Q/A engineer on board - our team consists of many office based developers - we always create a detailed divided by milestones project plan and follow it - all people are English speakers Want to know how much will be the development of your project? Send a free quote request now! Would be happy to help you! Contact me any time within the Upwork chat! Kind Regards, Artem

    I'm Volo, and I lead a product-first, no-code team specializing in Bubble.io development. If you're looking to find Product-Market Fit using Bubble.io, you should work with us. Why choose us: 1. We begin implementing specific features based solely on data (Hotjar recordings, user feedback, market insights), not because we think it might be cool. Before any Bubble.io development, my UX lead and I conduct comprehensive research to identify the product strategy for your no-code project. 2. In comparison to other development agencies, we excel in delivering exceptional designs using Bubble.io. Many clients have approached us for a UX review of their existing Bubble.io apps, which has often resulted in long-term relationships. 3. Compared to other product teams, we iterate faster because we use no-code tools like Bubble.io, rather than traditional coding, which is often complex and slow. 4. We maintain a sustainable development process on Bubble.io that is not only speedy but also bug-free. Developers do not handle application testing; we have a dedicated QA engineer for this purpose. 5. You will receive a dedicated Product Manager who will assist you in identifying the product strategy, conducting user interviews, analyzing the market, planning a roadmap, and defining the Bubble.io development scope. The Product Manager will also keep you updated on progress by preparing weekly reports with detailed Loom videos. 6. We do not have junior or intern-level team members; only Middle and Senior professionals well-versed in Bubble.io. Our tech stack: Bubble.io, Figma, JS/HTML/CSS If you've completed your MVP on Bubble.io and are struggling to address a drop in user engagement in a particular flow, or perhaps you have an app idea but don't know where to start, please reach out to me, and we will assist you in building a successful product using our no-code expertise!
