About the Writing

This is an engineering notebook maintained by Lucky Verma (handle: luckylinux), a B.Tech Computational & Data Science student at NITK Surathkal.

The focus here is entirely on technical writing: architectural notes, debugging post-mortems, distributed systems trade-offs, and practical how-tos drawn from building and maintaining real systems.

What I Write About

Topics covered in these notes center on reliable backend infrastructure and practical computer science:

  • Backend Architectures: High-throughput FastAPI asynchronous services, Django domain modeling, and PostgreSQL indexing strategies.
  • Container & Edge Ingress: Docker Compose setups, Cloudflare Tunnel (outbound-only zero-port architectures), and hardened Nginx reverse proxy routing.
  • Distributed Queues & Streaming: Redis task queues, Server-Sent Events (SSE), and WebSocket orchestration.
  • Object Storage: Cloudflare R2 dual-bucket isolation, temporary S3v4 pre-signed expiring download URLs, and zero-egress delivery pipelines.
  • Self-Hosted Infrastructure: Running homelab services including Nextcloud, n8n automation, Plausible analytics, and remote code-server environments.
  • Security & CTF Infrastructure: Hosting CTFd environments, container isolation, and edge Zero Trust policies.
  • AI Systems & RAG: LangGraph workflow orchestrations and retrieval-augmented generation pipelines.
  • Algorithms & Geometry: Applied graph algorithms, spatial indexing, and search-space pruning in real-world routing.
