So need someone who can fix this issue. Also kindly need to check overall functionality of the website if it’s working smoothly if any changes needs to be done please that also do it. Also need to add automation for message If someone books the lesson Instructor should get the text message currently only email part was working Currently for subscription email goes to admin only but I want that email goes to particular instructor to whom the lesson was booked and also in subscription there is no place for phone number to be added that also need to be added This same task was posted last week and I had assign one person looking at his reviews but he took almost 3-4 days and at last he is saying sorry I can’t do and canceled the task and refunded the money.

In addition he was saying if I search again please mention that person should be experienced in custom and dynamic part both as this website is made of up mix of both concept.

I’m looking for an experienced full stack developer to help my partner learn and refresh modern, end-to-end full stack web application development. This is not a request for website building or low-code / CMS-based development. I’m not interested in WordPress, Drupal, or similar tools. The focus is on understanding and implementing full-stack applications using mainstream development frameworks and platforms. I already have a strong understanding of core and advanced Java, so this is not a beginner engagement. The emphasis is on how full-stack applications are designed, built, deployed, and operated in real-world environments, with hands-on project work rather than theory. Scope of support includes: > End-to-end full-stack application and system architecture > Frontend development from a development perspective (frameworks, build tools, API integration) > Backend development (services, APIs, data access, security) > Databases and data layer design > Cloud deployment and hosting (AWS, Azure, or GCP) > CI/CD – Continuous Integration and Continuous Deployment / Delivery, including: >> Source control and branching strategies >> Automated build and test pipelines >> Deployment pipelines across environments (dev, test, prod) > Project-based work showing how all layers fit together > Practical guidance based on how production systems are delivered and maintained Engagement model: > One-on-one sessions (online preferred) > Fixed, package-based engagement (not hourly) > Clear learning plan with agreed outcomes Please include in your response: > Specific technologies you will teach, covering frontend, backend, database, cloud, and CI/CD > Proposed structure for a 1-2 month engagement (sessions + project work) > Your experience in full-stack development > Package inclusions and total fee

I am looking for an experienced web and mobile app developer (or small team) to design and build a service-matching marketplace platform with a similar look, feel and user experience to www.hipages.com.au (inspiration only, not a copy). This is a serious commercial project, so I’m seeking someone with proven experience building scalable platforms, not a basic website. The project will include a responsive website and a mobile app (iOS and Android) where customers can post jobs, service providers can create profiles and receive leads, and both sides can manage enquiries, bookings, messaging and reviews. The platform should have a clean, modern Australian-market design, intuitive UX, secure login, dashboards for users and providers, and a basic admin backend. You should be able to recommend the best tech stack, build a scalable backend with APIs for web and app, and ensure the platform is fast, secure and mobile-first. Experience with marketplace platforms, SaaS products or two-sided apps is essential. Ongoing support and the ability to build in stages (MVP first, then scale) is highly preferred. When applying, please include examples of similar platforms you’ve built, your recommended technology approach, estimated timeline, and a rough cost range. Australian-based developers are preferred, but not essential. Budget is flexible and can be milestone-based for the right person.
