𝗖𝗼𝘀𝘁𝗖𝘂𝘁𝘁𝗲𝗿 is a serverless, Python-based tool that helps users manage AWS resources and avoid surprise cloud costs. By monitoring budgets and automatically cleaning up resources when thresholds are exceeded, CostCutter keeps your AWS environment tidy and cost‑efficient. 🎯 𝗪𝗵𝗼 𝗶𝘁’𝘀 𝗳𝗼𝗿: ● Students experimenting with AWS for learning or coursework ● Freelancers or hobbyists wanting predictable cloud expenses ● Homelabbers and proof-of-concept developers on a budget ● Anyone using AWS Free Tier concerned about accidental cost overruns 🚀 𝗞𝗲𝘆 𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝘀: ● Automated Cost Monitoring - Integrates with AWS Budgets to track spending. ● Alerting - Sends notifications via SNS when thresholds are crossed. ● Serverless Cleanup - Uses AWS Lambda (Python + boto3) to delete resources automatically. ● Modular & Extensible - Each AWS service has its own module; adding new resource types requires minimal code changes. ● Safe & Deterministic - Proper deletion order prevents dependency violations; dry-run mode allows testing before actual execution. ● Observable & Transparent - Centralized event reporting with multiple output options (console, JSON, files). ● Scalable - Multi-region support with parallel execution where safe; designed for future multi-account use. 🛠 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 & 𝗗𝗲𝘀𝗶𝗴𝗻 𝗣𝗿𝗶𝗻𝗰𝗶𝗽𝗹𝗲𝘀: ● Atomic - Each resource type handles its own deletion logic. ● Modular - Resources grouped under service packages for clean separation. ● Scalable - Parallel, safe execution across regions. ● Observable - Centralized Pub/Sub for structured events. ● Extensible - Adding new resource types requires minimal effort. ● Deterministic & Safe - Ordering guarantees no dependency conflicts. CostCutter empowers users to experiment, learn, and build on AWS confidently, without the fear of unexpected bills.

Using the data from Normalized Difference Vegetation Index (NDVI) Climate Data Record (CDR), we determined the vegetation recovery rate after a forest fire. We studied the Bolivian region before and after a forest fire on 16th August 2010 with a total area of 360,000 sq. km. We used Panoply to extract Comma Separated Values and Python3 to filter the data and plot the graph to find the results.

I conducted an in-depth study on the structure and electrical characteristics of Cadmium Chalcogenides. Our research revealed that these materials are the most stable among the studied polymers, showing promising structural, electronic, and optical properties. They are optically active across the IR, visible, and UV spectrum, making them suitable for applications in sensors and photodiodes. Our findings suggest that Cadmium Chalcogenides are a versatile and promising semiconductor material capable of operating across a wide range of the electromagnetic spectrum.
