Engagement: Architecture engagement. Architecture and design scope; this is not a claim of a live production deployment.
The capabilities below describe the work delivered. Quantified business results have not been published.
Challenge
Identity, membership, education, and professional services needed shared access rules across mobile and web clients.
Solution
Avlys designed a five-layer stack — client, API gateway, application services, data, infrastructure — so new modules can attach without a rebuild. Cover is the architecture the team uses.

Architecture explained in text
The proposed HJSN architecture groups Android, web, public-site, admin, and third-party clients above an API gateway. Application modules cover identity, membership, education, profiles, professional help, notifications, content, and AI. Proposed data services include Postgres, Redis, vector search, object storage, search indexes, and audit logs. Infrastructure and cross-cutting concerns are design considerations. Identity verification and other external integrations require authorization and provider approval; the diagram is not evidence that these integrations are live.
Delivered.
Android and web client architecture
Identity and membership service design
Education and help-network module design
Verification and payment integration boundaries
Design outcomes.
Mobile, web, and admin share one gateway.
Identity verification is a service, not a one-off screen.
Vector search and object storage sit beside Postgres, not as a second product.
Infrastructure and cross-cutting concerns are defined alongside the application layers.
How it was designed.
01
Mapped mobile, web, admin, and third-party client needs.
02
Separated identity, membership, education, and professional service responsibilities.
03
Defined data stores and external integration boundaries.
04
Documented proposed infrastructure, access controls, and operational concerns.
