The Workplace Basics

A multi-module Django platform combining a public sector blog, tiered subscription service, digital product marketplace, and newsletter system — covering public administration, policy, and electronic support systems.

  • Paystack integration — recurring subscription billing, one-time orders, and HMAC-SHA512 webhook verification for charge, invoice, and subscription events
  • Tiered access model — free and premium content gates with subscription plan management and JWT-backed session tokens
  • AWS S3 media storage — versioned file uploads with presigned URLs, lifecycle policies capped at 3 versions, and Pillow-based thumbnail generation
  • Async infrastructure — Celery + Redis for email dispatch and payment verification; Celery Beat scheduling; Papertrail log aggregation with per-module log streams and health-check endpoints covering cache and storage layers

Django · Municipal Planning System

e-PGLUM

Electronic Planning and Land-Use Management — a Django platform handling land development and building plan applications across multiple jurisdictional levels. Deployed live for CoGHSTA, Mpumalanga.

  • Configurable workflow engine — stage transitions stored as database models with Django signal automation, keeping flow logic decoupled from application code
  • Layered permission model — custom middleware enforces group-backed access checks on every request; jurisdiction-scoped data isolation applied at the query level
  • Async document pipeline — Celery queues S3 uploads off-request on a polling interval; presigned URL retrieval on access
  • Celery Beat automation — nightly tasks aggregate application statistics and publish counts; account inactivity and maintenance windows enforced at the infrastructure level

Django · Provincial Citizen Services

Livi — Civic Services Platform

Livilemphakatsi is a multi-tenant provincial citizen services platform built for the Office of the Premier, Mpumalanga. Ten departments each operate on a branded subdomain with isolated sessions, routing citizen cases from web and mobile channels through a SLA-enforced workflow to resolution. Moving to production.

  • Subdomain multi-tenancy — 10 government departments, each with branded portal, isolated auth, and per-department CSS theming via CSS variable overrides
  • Unified case ingestion — web and mobile submissions normalised into a single processing queue; composite key generation binds each case to department, municipality, and year at creation
  • SLA engine — Celery Beat drives SQS polling and timed compliance checks; due dates calculated per service profile with automatic escalation on breach
  • Amazon MQ RabbitMQ — 12 domain-partitioned queues fan outbound case events and service-domain data to external consumers; AWS Rekognition gates inbound media before storage

Static Web · Community Program

Community Web Modernization

An annual pro-bono programme by DevBridge replacing outdated, insecure websites for South African community organisations — schools, nonprofits, agricultural co-operatives, and housing bodies — with fast, maintainable static sites and full source ownership transferred to each institution.

  • Static architecture — eliminates server runtime, database vulnerabilities, and ongoing security patching
  • Cloudflare edge delivery — global CDN with automatic HTTPS, DDoS protection, and zero-downtime deploys
  • Git-based deployment — push-to-live workflow on GitHub Pages, Netlify, or Cloudflare Pages
  • Full institutional handover — complete source ownership, content update guides, and no vendor lock-in
