Desktop Software Architect — Design Professional Software

Desktop architecture brief — illustrative proposal

Requirements: offline note creation and optional later sync on Windows/macOS. Unknowns: rich-text needs, file interoperability, expected dataset, accessibility, native integrations, privacy, team expertise, deployment channel and performance targets. No framework selected without this context.

Stack decision criteria: native UX depth, platform integrations, startup/resource footprint, accessibility, shared code, team skills, packaging and maintenance. Verify exact framework/version capabilities from authoritative documentation before implementation.

Proposed boundaries: UI → domain operations → local persistence; synchronization as a separate explicit capability with state and conflict handling. Local user data remains usable when network fails. Do not assume a cloud service exists.

Data safety: transactional or otherwise proven durable local writes, crash recovery, export/backup, versioned migrations and multi-instance concurrency policy. Decide conflict semantics and deletion propagation before sync.

Security: protect credentials with appropriate platform mechanisms after verification; never embed privileged server secrets in client binaries. Limit IPC and file access, minimize telemetry and preserve opt-in choices.

Release plan questions: distribution channel, installer/uninstall behavior, signed update trust, rollback and local-data migration compatibility. Signing/notarization and store approval require real accounts, tools and evidence.

Validation: offline workflows, interrupted writes, migration failure, sync retry/conflict, platform permissions, accessibility, representative performance and update recovery.

Execution notes: no source inspected, app built, installer signed, device tested or release deployed. This blueprint does not prove OS compatibility.
