Hi, I'm Tanisha. I build backend logic and cloud infrastructure.
AWS Certified Cloud Practitioner. Final-year student in India. I love organising massive tech events, but right now my focus is writing clean Python and understanding how the internet works under the hood.
About
I'm a final-year BCA student at Banasthali Vidyapith with a deep interest in the "hidden" parts of the internet – the servers, databases, and logic that keep it all running.
Over the last year I validated my architecture knowledge by earning my AWS Cloud Practitioner certification, and sharpened my communication skills as Workshop Lead for Mayukh, my university's national-level tech fest.
Right now I'm in a focused engineering sprint – mastering core Data Structures in Python and building out the backend for my team's AI-driven final year project.

Sentinel: AI-Driven NIDS
Final YearA net that watches the network.
A team project building an AI-driven Network Intrusion Detection System. I'm responsible for the core Python backend – logic that analyses network packets in real-time and flags security threats before they escalate.

Flux-Order: Ticketing Engine
Cloud ArchitectureTwo people. One seat. Same millisecond.
I wanted to understand how apps survive flash sales. Built a ticketing backend using Redis Distributed Locking to prevent two users from buying the same ticket at the exact same millisecond. Infrastructure automated with Terraform.

Bill-E: Serverless Risk Engine
Event-DrivenCosts $0 when idle. By design.
An exploration into serverless computing and cost optimisation. An event-driven pipeline (S3 → SQS → Lambda) runs OCR on receipts and flags fraudulent anomalies, firing SNS alerts for anything scoring above 50. Decoupled architecture means it costs $0 when idle.

Beyond the editor
Experience & leadership
Workshop Lead – Core Team
Mayukh Tech Fest · Banasthali Vidyapith
Led end-to-end logistics for technical workshops in the 2026 edition after being promoted from the 2025 sub-core team. Managed speaker relations, resource allocation, and coordinated resources for 500+ attendees. Mentored a sub-core team to execute live events.
Seasonal
AWS Certified Cloud Practitioner
Amazon Web Services · CLF-C02
Validated foundational understanding of cloud concepts, security, and architecture. The stepping stone that bridged the gap between my college syllabus and real-world infrastructure.
Bachelor of Computer Applications
Banasthali Vidyapith
Final-year student, 8.15 CGPA. Built a strong foundation in C, Java, and core computing before pivoting toward Python and cloud-native backend development.

Things I've figured out.
Distributed Systems
Why Redis Distributed Locks Actually Solve the Double-Booking Problem
I built a ticketing engine and learned the hard way that optimistic locking isn't enough when two threads hit the same resource in the same millisecond. Here's what a Redis mutex actually does.
Serverless
The $0 Architecture: How Event-Driven Serverless Actually Achieves Idle-Cost Efficiency
Everyone says serverless is cheap. Not everyone explains why – or when it isn't. Bill-E taught me exactly where the cost boundaries are in an S3 → SQS → Lambda pipeline.
Real-Time Systems
What Building a Packet Sniffer Taught Me About How the Internet Actually Works
Before Sentinel, I thought I understood TCP/IP. Writing Scapy code that parses raw packets in real-time changed that. The gap between theory and what actually moves across the wire is enormous.
What's next
Let's build
something
together.
I'm actively looking for full-time backend or cloud roles starting after I graduate in May 2026. Whether you have an open position, want to talk AWS architecture, or just want to say hi – my inbox is open.
