Software Engineering Standards

How production software is engineered, not just coded

Beyond frameworks and features: engineering discipline for systems that need to survive real users, real devices, real traffic, and real business constraints.

01 · Architecture Decision Records

Important architectural choices are documented with trade-offs, constraints, and consequences so a product remains understandable as the team grows.

02 · Contract-First APIs

Explicit API contracts, validation, versioning, and predictable error semantics reduce fragile coupling between the app and backend.

03 · Observability

Production telemetry should answer what failed, where, for whom, and why—through structured logs, useful metrics, traces, and actionable diagnostics.

04 · Security Threat Modeling

Authentication, authorization, secrets, abuse cases, data boundaries, and attack surfaces are considered before they become production incidents.

05 · Automated Quality Gates

Formatting, static checks, unit/UI tests, build verification, and release checks belong in the delivery pipeline—not in a last-minute manual checklist.

06 · Performance Budgets

Startup time, memory, network work, battery impact, rendering smoothness, and payload size are treated as engineering constraints with measurable targets.

07 · Failure & Recovery Design

Offline states, retries, timeouts, partial failures, degraded modes, backups, and recovery paths are designed deliberately instead of handled accidentally.

08 · Release Engineering

Versioning, CI/CD, signing, staged releases, rollback thinking, App Store readiness, and reproducible builds turn shipping into a controlled process.

09 · Feature Flags & Safe Rollouts

Risky changes can be isolated, tested progressively, disabled quickly, and released independently from the full application lifecycle.

10 · Accessibility & Inclusive QA

VoiceOver, Dynamic Type, contrast, touch targets, keyboard/pointer flows, localization, and real-device usability are part of quality—not optional polish.
