#Laravel

The personnel information system of the City Government of South Tangerang: employees keep their own records and follow their services, administrators work on exactly their part of the organisation, and every rule comes from the regulation that sets it. Led and built by me since 2023.

The Laravel core of a civil-service personnel system: employee records and career histories, self-service proposals with review, salary-step, promotion and retirement decisions, rules taken from regulations, a versioned organisation chart, and access scoped down to a single unit.

Administrators of a city government's personnel system must each touch only their part of it: everything, one agency, or one unit. I made the scope data — a grant is user, role and scope — checked by one rule, requested and approved by different people, and expiring on its own.

An organisation chart that changes by regulation is still master data for relational records. I keep it in SQL as a table that points at itself, with versions per agency and effective dates, read it with one query and recursive CTEs, and leave drawing it to the interface.

The Laravel core of a document-signing platform: it owns users, identities, organisations, client systems, documents and their signed versions, stamps, and certificates, and orchestrates the services that sign, timestamp, render, and store — without ever holding a file.

How I run Laravel as the core of a team-built platform: nodes that hold no state, slow work handed to queued jobs and specialised services, files kept off the server, one internal token for every login, and every request, job, and call observable.

The digital signature platform of the City Government of South Tangerang: signers prove who they are, sign PDFs to PAdES B-LTA with certificates from the platform's own authorities, and anyone can verify the result — version 2, which I designed, built and operate.

This Laravel app answers HTTP and runs long-lived queue workers, yet a container is meant for one program. A process manager, FrankenPHP worker mode and a cache-ordered build put both in one image, instead of building the same code twice.
