01 / CONTEXT

A system shaped by real-world constraints.

The product coordinates a multi-stage Certificate of Occupancy process across operational roles, payments, approvals and final issuance.

02 / ROLE & OWNERSHIP

Where I contributed.

Full-stack engineering across secure access, workflow interfaces, shared services and operational data tooling.

03 / CONSTRAINTS

What made the work difficult.

Different roles needed controlled access to specific workflow stages and operational records.
Large result sets needed reliable server-side filtering and pagination without fragmenting frontend behavior.

04 / ENGINEERING DECISIONS

What mattered technically.

Explicit workflow stages

Modelled the Certificate of Occupancy process as a multi-stage workflow from application through approval and issuance.

Reusable operational grids

Built shared data-grid behavior around server-side filtering and pagination.

Centralised application boundaries

Used shared services and centralised error handling to keep frontend behavior consistent as the workflow surface expanded.

05 / RELIABILITY & SECURITY

Correctness beyond the happy path.

Access uses OTP and JWT controls together with request signing and encrypted payload exchange.

06 / TECHNOLOGY

Technology should support the system, not become the story.
