Solo Entrepreneur Edition – A modular, production‑grade pnpm monorepo powering my business operations, content management, CRM, and automations.
Built with Keystone.js 6, Prisma, Next.js 14, Playwright, pg‑boss, and a shared TypeScript codebase.
Designed for:
- Single source of truth for all business data
- Scalable microservice pattern within a monorepo
- Shared code & types across apps
- Queue‑aware ingestion to decouple heavy scraping from API requests
Purpose:
To unify all business‑critical systems in a single, maintainable codebase — enabling rapid feature growth, consistent data models, and seamless integration between backend services, automation workers, and the public landing page.
A modular, scalable product information management system for e‑commerce platforms.
Built with Node.js/TypeScript, Keystone.js, GraphQL, PostgreSQL, and Redis.
Deployed on Azure Cloud with CI/CD pipelines, RBAC, and API‑Security.
A fully integrated, off‑cloud, privacy‑aware smart‑home ecosystem.
Runs on a local Docker‑Swarm cluster with Traefik, GlusterFS, and multiple IoT services.
Supports IR, BLE, ZigBee, WiFi, and wired integrations.
Managed with Ansible for orchestration, ensuring high availability and maximum data privacy.
Queue‑based commit message generator leveraging Azure OpenAI and LangChain.js.
Optimized for developer workflows and semantic commit standards.
Event‑driven text‑to‑speech pipeline with multi‑channel input support.
Integrates with IoT devices and conversational AI interfaces.
