I’m looking for an experienced web application developer to help me refresh and upskill across modern, end-to-end web application development. I already have a strong understanding of core and advanced Java, so this is not a beginner request. The focus is on current, industry-relevant technologies and hands-on implementation rather than theory. Scope of support includes: > End-to-end web application architecture > Frontend development (modern frameworks, best practices) > Backend development (APIs, services, integrations) > Cloud deployment and hosting (AWS, Azure, or GCP) > CI/CD (Continuous Integration and Continuous Deployment / Delivery) >> Source control workflows >> Automated builds and testing >> Deployment pipelines for frontend and backend >> Environment setup (dev, test, prod) > Real-world project-based work to tie everything together > Practical guidance based on how teams work in production environments Engagement model: > One-on-one sessions (online preferred) > Structured, package-based offering (not hourly) > Clear learning plan with defined inclusions and outcomes Please include in your response: > Technologies and tools you would cover > Proposed structure or roadmap (sessions + project work) > Your experience delivering similar training or mentoring > Package inclusions and total fee Looking for someone hands-on, up to date with modern web stacks, cloud deployment, and CI/CD practices, and able to explain concepts clearly and practically.

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.
