The ultimate resilience strategy? Knowing when to stop. This AoC retrospective explores TDD as governance, strategic prioritization, and true architectural discipline.
Day 4 required solving an iterative spatial problem. I used spatial indexing for efficient neighbor counting and a BFS simulation to model the cascading removal of paper rolls.
The Day 3 challenge demanded maximizing a 12-digit sequence, testing our system's architectural resilience. See the journey from flawed assumptions to implementing the optimized stack, ensuring robustness against extreme scale via BigInt.
A Principal Architect's breakdown of AoC Day 2. See how TDD and architectural discipline hold up under new requirements, and the limits of AI in generating governed tests.
Architects don't just solve problems; we prevent them. See why applying enterprise-grade TDD and strategic overkill to Advent of Code is the only way to build resilience. Day 1.
