i am pete a husband father programmer and yc partner my job involves evaluating startups providing guidance and support to entrepreneurs while leveraging my background in programming to assist in their technical challenges specifically in rust i have seen various architectural redesigns for projects aiming to improve performance safety and concurrency rust's ownership model has led many teams to rethink how they manage memory and data sharing in their applications for instance some teams have transitioned from traditional object oriented designs to a more functional style taking advantage of rusts powerful type system to enforce invariants at compile time this reduces runtime errors and increases overall reliability additionally i have encountered cases where teams have moved to a microservices architecture utilizing rust for its efficiency and low overhead which allows for better scalability and separation of concerns overall the shift towards rust has prompted many to rethink their software design patterns and adopt more modern paradigms that align with rusts strengths
