Lead architecture across teams.

Goal: stop being measured only by features shipped personally. Staff-level Android work improves how many teams build, test, migrate, observe, and release mobile software.

What to learn

• Architecture strategy: target state, transition state, migration sequencing, and compatibility policy.
• Shared platform design: design systems, networking, analytics, experimentation, authentication, and release tooling.
• Observability: crashes, ANRs, latency, startup, funnels, logs, traces, and actionable dashboards.
• Technical decision records: context, options, decision, consequences, rollback plan, ownership.
• Cross-team influence: RFCs, alignment meetings, technical debt negotiation, and phased adoption.
• Risk management: migration blast radius, dependency health, policy changes, platform deprecations.

Build this project

Write and implement a migration case study: XML to Compose, monolith to modules, RxJava to coroutines, or legacy networking to a typed client. Include code, metrics, and the social rollout plan.

Staff-level artifact set:
- Architecture decision record
- Migration sequence
- Compatibility policy
- Testing strategy
- Rollback plan
- Adoption dashboard
- Post-migration review

Exit gate

• You can reduce risk for multiple teams, not just deliver one feature.
• You can design migrations that keep product delivery moving.
• You can define platform contracts other engineers can use correctly.
• You can identify weak metrics and replace them with actionable evidence.
• You can explain engineering investment in product and business terms.
