There is a need to understand and breakdown the requirements. Generally you need to classify requirements in the below categories - Functional - What are the use-cases, functionalities etc - Non-functional - Scale, amount of data, organic growth Based on the above a MVP version can be designed and then checked for feasibility. The design needs to done in a evolutionary manner as and when the system grows. There is no silver bullet for system design and just trade-offs. One needs to consider what is the best trade-off you can live with. Building abstraction based systems can help with shipping features faster. It may start slowly but works well in longer run.

Balancing complexity with the pressure to deliver faster timelines requires careful prioritization, clear communication, and flexibility. - Clarify and Prioritize Requirements. - Scope Reduction and Simplification. - Communication and Manage Expectations. - Leverage Automation and Tools. - Team Collaboration and Expertise.

Here are some strategies: Prioritize Features: Focus on essential features for the initial release, deferring others Leverage Agile: Use Agile practices for iterative development and continuous feedback Negotiate Milestones and keep stakeholders in loop: Break the project into manageable phases with realistic deadlines and update on progress and roadblocks to stakeholders Cross-Functional Teams: Form cross-functional teams to enhance collaboration and streamline the development process Automate Testing: Implement automated testing to quickly identify and fix issues, ensuring quality without slowing down development. Risk Management: Identify and mitigate potential risks early

With limited time, there's less creativity, the goal is to maximize coverage of the Definition of Done without anything extra, without creating bicycles, and using technologies familiar to team members. Team need to sacrifice everything for the sake of a working result and nothing more. Maximum communication within the team with minimal waste on unnecessary meetings with the outside world (let someone else handle that, for example, a BA). Daily meetings every day with the product owner or another responsible person present. That's all if you need to make a product on yesterday.

Such demand should not be rejected aitomatically, some times this is a question of what is the cost, work around, changes in priorities or some external help. This atitude can some times help to face chlanges together. Other wise you can find your self alone.
