02 / SELECTED WORK
GMAHSA — Student Membership Platform
A live Django/PostgreSQL platform for the Government Medical Allied Health Science Students Welfare Association (GMAHSA), centralizing student registration, membership management, payments, events, documents and role-based administration. I integrated Razorpay, OTP verification and transactional email across the core workflows.

Billing & Business Operations Software
A full-stack billing and business operations platform currently in development for small businesses. The V1 is structured around customer and product/service management, invoicing, payments, outstanding balances, inventory, expenses and reporting, using a modular backend and relational PostgreSQL data model.
IN DEVELOPMENT
Airline Revenue Management
A predictive analytics project for airline demand and ticket-pricing analysis using 98,619 records and 24 features. I handled preprocessing, feature preparation and model evaluation across Random Forest, XGBoost and LSTM; XGBoost produced the strongest result with R² ≈ 0.9725 and RMSE ≈ 55.15.

Background
Software development backed by strong data foundations.
I build web applications and backend systems with Python, Django, TypeScript, Next.js and PostgreSQL. My recent work includes a live Django association platform, an in-development billing and business operations system, production websites and applied data projects.
I hold an MSc in Data Science from the University of East London and a B.Tech in Information Technology from University College of Engineering, Trichy. The combination gives me practical software-development experience alongside Python, SQL, data processing and machine-learning knowledge.
Python & Backend Development
Django, APIs, databases, authentication and production-oriented application logic.
Full-Stack Development
Next.js, TypeScript, Django, APIs, responsive interfaces and deployment.
Data Science Foundation
Analytics, machine learning and data-informed problem solving.
04 / JOURNEY
Journey
Learning, building, then shipping.
The path is not a corporate ladder. It is a sequence of stronger problems, better tools and more responsibility.
B.Tech IT

MSc Data Science
Analytics, modelling, machine learning and data-driven thinking.
Production Work
Client-facing applications, production websites and the live GMAHSA platform.
Software Engineering Focus
Maintaining a live Django platform while developing a full-stack billing and business operations system.
