Idea-Phase Software Development Consultation in what languages and database to use

I am a technology consultant with previous professional experience involving 5 years of working with a telecommunications client that serves more than 50 million customers. I've worked on numerous projects that require heavy understanding of business processes to model and design complex production ready systems. Some experiences that highlights my expertise and relevance to your needs is: 1. Product Owner - Currently working as a product owner for a small startup in Australia aiming to improve recycling and sustainability practices. My responsibilities includes working with the client to understand their business ideas, convert them into user stories, and work with the development team to deliver a great product. 2. Senior Software Engineer - As senior software engineer, this involved technical discussions with both the client and our internal development teams. Part of my work was managing the team and ensuring tasks were delivered on time and to specification. That meant planning the project as part of a software development lifecycle. This also includes the process of choosing which programming language, database, and deployment architectures. As a young independent consultancy, I pride myself on offering personalized service and specialized attention to my clients. With my experience and dedication, I am confident in my ability to contribute effectively to the success of your project. Looking forward to knowing more about the project and working with you!
