Architecture

  • Three-layer setup: Astro public site, React/TypeScript admin panel, and NestJS services with a shared API contract.
  • Domain boundaries kept honest — the public site never speaks to the internal table shapes directly; everything goes through the API.
  • Shared component library used by both the public site and the admin panel, so design and behavior stay consistent.

Data & infrastructure

  • PostgreSQL + Drizzle ORM as the system of record, with clean migrations and typed schema shared with the API layer.
  • Keycloak for authentication and identity, including role mapping across the admin panel and API.
  • Redis for cache, queues, and realtime channels — used to keep long-running operations off the request path.
  • MinIO for object storage (clinical files, attachments) and Mailgun for transactional email.

Delivery

  • Docker Compose for local and staging environments; production deploys through GitHub Actions on each merge to main.
  • Backups, scheduled jobs, and observability baked into the same Docker Compose stack so environments stay reproducible.

Platform

  • Next.js application with ISR (Incremental Static Regeneration) for snappy public pages, paired with webhook-driven content sync to keep editorial sources in sync.
  • Editorial workflows stay close to the source of truth: status transitions, draft / publish states, and scheduled updates.

Visualization

  • React Flow for user networks and hierarchical data visualization, with custom node and edge types tailored to the domain.
  • Performance work on large graphs: virtualization, lazy loading of branches, and node prioritization for the initial render.

Workflow & orders

  • Internal workflow system with explicit status transitions, work orders, and clean handoff between stages with audit history.
  • Ordering module with cart, checkout, and admin-side payment-receipt validation, including reconciliation with backend payment records.

Stack

  • React, Next.js and Node.js, with MongoDB or PostgreSQL depending on the workload — the same mental model across clients keeps iteration fast.
  • Serverless-first backends when traffic is spiky, traditional Node servers when the project needs background jobs or long-lived connections.

Integration work

  • Communication automation and third-party API integrations: email, WhatsApp bridges, payment gateways, and lightweight internal tools.
  • Designed for low-maintenance handoff: clean env vars, seed scripts, and short README files so the client can keep things running without me.

How I work

  • End-to-end ownership: from requirements gathering and scoping through deployment and ongoing support.
  • Clear handoffs: documented data flows, exported credentials, and a recorded walkthrough when a project moves in-house.
