The SentinelStream -Autonomous Mesh

 

This playbook is now your complete 360-degree architectural reference for the 2026 digital economy.


The SentinelStream Manifesto

SentinelStream is an end-to-end manifesto for the "Autonomous Bank." It moves beyond legacy monolithic architectures into a Distributed Data Mesh where data is not just stored, but reasoned with in real-time. The system is designed to handle 100,000+ Transactions Per Second (TPS) with sub-100ms latency, utilizing Agentic RAG for fraud triage, Citus-sharded PostgreSQL for horizontal scale, and GitOps for self-healing infrastructure. It bridges the gap between high-speed transactional logic and deep analytical intelligence.

"Depth-Guard" – 3D Spatial Occupancy monitor Challenge -2

  Project Title: "Depth-Guard" – 3D Spatial Occupancy Monitor 1. The Problem In a smart warehouse, a robot needs to know if a loading zone is clear or occupied. A 2D camera alone can’t tell the difference between a "flat picture of a box" on the floor and an "actual 3D box." The Goal: Build a Python-based system that uses Computer Vision and Depth Perception (AI 3D) to identify objects and determine their 3D volume (Size) and Distance from the camera. 2. Intern Tasks Object Detection: Use a pre-trained model (like YOLOv8) to draw 2D boxes around objects. Depth Mapping: Use a depth estimation model (like MiDaS or a simulated Stereo-depth feed) to calculate how far each object is. Occupancy Logic: If an object is closer than 1 meter and larger than a specific volume, mark the zone as "BLOCKED." Alert System: Print a warning if the 3D space is too crowded. 3. Sample Datasets (Simulation) Since interns may not have 3D cameras (LiDAR/RGB-D), pr...

Simple Virtual Waiting Room -Challenge 1

   Simple Virtual Waiting Room (VWR) 1. The Problem Our website can only handle 10 users per minute . If more than 10 people try to access it at once, the server will crash. We need a system that: Counts incoming users. Redirects "overflow" users to a waiting page. Admits them back to the main site one by one as space becomes available. 2. Intern Tasks Create a Gateway: A simple script that checks: if (active_users < 10) { allow } else { send to queue } . Build the Queue: Use a simple list (FIFO) to store user IDs. The Wait Page: A basic HTML page that says: "You are number X in line. Estimated wait: Y minutes." Admission Logic: Every 30 seconds, pull the next user from the queue and "admit" them. 3. Sample Datasets (Simulation) Provide these two datasets to the interns. They should write a script to "read" these files and simulate how their system reacts. Dataset A: The Traffic Surge (Input) This file simulates users arriving at the ...
