Hi, I'm Ashmita Mazumdar ๐Ÿ‘‹

Computer Science Undergraduate ยท Full-Stack & Backend Developer
B.Tech CSE @ SVKM's NMIMS (MPSTME), Shirpur ยท Class of 2028

Portfolio LinkedIn Email


I build complete, tested, deployed systems: event-driven backends, databases that do real work, and clean frontends on top. My recent work includes a Kafka-based fraud-monitoring platform, a fraud engine written inside Oracle with PL/SQL, a compiler I wrote by hand from lexer to C++ code generation, and a webcam-controlled game built with classical computer vision.

  • ๐Ÿ”ญ Focus: backend engineering, event-driven architecture, databases, and full-stack web apps
  • โœ… How I work: every project is deployed live and backed by automated tests and CI (450+ tests across projects)
  • ๐ŸŽฏ Looking for: Software Engineering internship opportunities

๐Ÿš€ Featured Projects

๐Ÿ’ณ FinPulse โ€” Real-Time Fraud Monitoring Platform ยท Live Demo

FastAPI Apache Kafka PostgreSQL WebSockets React TypeScript Docker Airflow

  • Event-driven pipeline: API โ†’ PostgreSQL โ†’ Kafka โ†’ risk engine โ†’ WebSocket, pushing APPROVE / REVIEW / BLOCK decisions to the dashboard in real time
  • Risk engine scores amount, new-device, transaction-velocity and behavioural-anomaly signals, with explainable reasons
  • 6 containerized services behind an Nginx reverse proxy; CI with Pytest, Jest and Cypress end-to-end tests

๐Ÿฆ SmartBank โ€” Database-Driven Fraud Detection ยท Live Demo

Oracle 21c PL/SQL ORDS React 19 Playwright

  • Fraud detection runs inside the database: a compound trigger scores every transaction, raises alerts and assigns them to the least-loaded analyst
  • Normalized 12-table schema with constraints, reporting views and indexes checked with EXPLAIN PLAN
  • Authenticated REST API with role-based access, a two-role React dashboard, and 150+ automated checks

โš™๏ธ CodeBridge โ€” Pseudocode-to-C++ Compiler ยท Live Demo

Python FastAPI React TypeScript C++17

  • Every phase hand-written, no parser generators: lexer, recursive-descent parser, typed AST, semantic analysis, three-address code, optimizer, C++ code generator
  • Optimizer verified by a 300-program randomized differential test; 233 tests in total, including g++ build-and-run checks
  • Interactive workbench that shows tokens, AST, symbol table, original vs. optimized TAC, and the generated C++ live

๐ŸŽฎ Pixel Quest โ€” Webcam-Controlled Arcade Game ยท Play in Browser

Python OpenCV NumPy Pygame

  • Steer a spaceship by moving a coloured object in front of your webcam, tracked in ~1.2 ms per frame at 60 FPS
  • Classical computer vision only: HSV segmentation, morphology, contour centroids and motion smoothing
  • 65 tests using synthetic frames and fake cameras, so no webcam is needed to run them
More projects
  • Developer Portfolio: interactive portfolio with a command palette, GitHub activity and scroll-driven animations. React Vite Tailwind CSS GSAP Framer Motion
