Pikachu-5/README.md

Hello

Software & ML Engineer (Student) | Python • Rust • React • Data Engineering

I love building systems that are fast, intelligent, and actually usefulm from high-performance search engines in Rust to ML models that explain their predictions. Passionate about AI/ML, full-stack engineering, system design, automation, and everything F1.

Currently Working On

F1 Podium Predictor

Predicting top-3 F1 race outcomes using Gradient Boosting Regressor + FastF1 Telemetry + Weather Data.
Also experimenting with Gemma 3.0 for natural-language race insights (e.g., “Why did Mercedes dominate 2014–2020?”).

Featured Projects

SwiftSearch — Hybrid Semantic + Keyword Search Engine (Rust + Python)

A lightning-fast local search engine using:

  • Tantivy for full-text indexing
  • ANN-based embedding store for semantic search
  • Sub-millisecond lookup
  • ~1GB vector store indexing ~100GB of files
  • Multi-threaded preprocessing + memory mapping

GTFS Metro Network Visualizer (React, MapboxGL, SQL.js)

Offline transit system that:

  • Loads GTFS schedule + real-time data
  • Renders 500+ route points
  • Shows live positions, next stations, trajectory playback
  • 80% faster data recomputation using optimized caching

Multimodal Pneumonia Severity Estimator (CNN-ViT + Grad-CAM)

Hybrid CNN-ViT model for severity grading (“Mild/Moderate/Severe”).
Includes full preprocessing, proxy labeling, Grad-CAM explanations.
Under review at AIHC 2025.

Password Manager (Python)

Local credential manager with encryption, salting, hashing, and secure storage.

AI Agent with RAG (LangChain)

Custom document Q&A system using vector embeddings, FAISS, and LLMs.

CIFAR-10 Image Classifier (TensorFlow)

CNN for 10-class image recognition with augmentation + visualization.
