Tech Lead

Design Patterns

Pourquoi : You can tell when a pattern is over-engineering and push back in design review, because you know what it costs the next reader.

System Design

Pourquoi : You can design a service whose boundaries survive the next two quarters of requirements, not only the current ticket.

Code Review

Pourquoi : You can set review norms for the team, such as size limits and turnaround, so reviews spread knowledge and stop being a bottleneck.

Testing Strategy

Pourquoi : You can rebalance a test suite that has grown slow and brittle, deciding which tests to delete, push down a layer or keep.

Identifying Tech Debt

Pourquoi : You can separate deliberate shortcuts from accidental mess and bit-rot in a codebase audit, so each kind gets a different response.

Quantifying Impact

Pourquoi : You can show that a flaky module costs the team hours of rework each sprint, giving the debt a number a product manager can weigh.

Pair Programming

Pourquoi : You can pair with a newcomer on a hard bug so they learn the debugging approach, not just receive the fix.

Tech Talks

Pourquoi : You can turn a lesson from a recent migration into a short internal talk that changes how the whole team approaches the next one.
