01 — Problem

The professional body for psychological counselling and guidance ran member records in a legacy membership system, its website in a separate Laravel app, and training, dues, documents and its store as disconnected processes. No one could see a member's dues history, documents and training record in one place.

02 — System

We built a modular association platform that unifies the public site, member area and admin panel on a single Node/Next stack. From membership application to board decision, dues collection to certificates submitted to e-Devlet, store order to shipping label and e-Archive invoice, every process runs on the same data model. Legacy records were migrated without fabricating a single value and without losing a single file.

Membership application

Every step from application to member ID card is governed by a state machine.

03 — Architecture

Site and admin apps, separated by distinct session audiences, talk to one API. Data is split into separate schemas by business area; email, SMS and scheduled jobs are drained from a queue by a dedicated background process.

04 — Capabilities

  1. 01

    Membership lifecycle

    Full, honorary, corporate and emeritus applications; required-document workflow, board review, member-number allocation, and state machines for suspension, resignation and honorary-to-full transitions.

  2. 02

    Dues and collection

    Period-based debt standing, pay-everything-open in a single link, card payments with instalments, manual collection by bank transfer receipt, bulk operations and dues reports.

  3. 03

    Learning management

    Program → cohort → session structure, member pricing tiers, exams and surveys, automatic attendance from video-conference reports, recordings, refunds and training reports.

  4. 04

    Certificates and verification

    Template editor, HTML→PDF rendering, QR codes and barcodes, numbering, revocation, a public verification page, and certificates submitted to e-Devlet automatically.

  5. 05

    Store, shipping and e-Archive

    Catalogue with variants, campaign and coupon rules, stock movements, returns; barcodes and tracking through the shipping integration, and UBL e-Archive invoices through an integrator — enabled in production.

  6. 06

    Governance

    Units, terms, mandates, board and committee assignments, meetings, ethics-board operations, an org-chart PDF and an accreditation case workflow.

  7. 07

    Career pool

    A career space where members join with a private CV and employers post opportunities; CV sharing sits behind a legal-approval flag.

  8. 08

    Support and notifications

    Ticket queue with auto-assign and auto-close, reply templates, satisfaction scoring; transactional email and SMS, editable templates and bulk sends.

05 — Impact

  • 01

    Membership, dues, training, store and governance now share one data model.

  • 02

    Records, dues history and documents moved off the legacy membership system without inventing a single value.

  • 03

    Shipping and e-Archive integrations are live; order, label and invoice run in one flow.

  • 04

    The PDOK and EPDAB sub-sites share the same CMS pattern and run on their own databases.
