Internal Staff Intranet

Internal tool · Next.js & PostgreSQL

An internal intranet I built on my own initiative at work: employee directory, organizational structure, ISO documentation, learning resources, and printer/cartridge stock. Armenian-language Next.js app backed by PostgreSQL, running on the office LAN.

  • Built the employee directory, executives page, ISO document section, and internal learning pages.
  • Added printer and cartridge inventory with replacement history and PIN-protected admin editing.
  • Deployed on the office LAN with Docker and Dokploy; maintain deploy, rollback, and health-check scripts.

A multi-tenant SaaS CRM engine featuring automated subscription billing and two-way omnichannel messaging across Telegram, Instagram, and Messenger.

  • Engineered two-way sync for Telegram, Instagram, Messenger, and Viber with webhook pipelines and live chat.
  • Architected backend services with NestJS, Prisma ORM, and PostgreSQL with tenant data isolation.
  • Implemented session handling, caching, and rate limiting with Redis and automated billing webhooks.
