Hi, I'm Bhavdeep Arora

I'm a systems focused software engineer based in Toronto. I've been programming for over six years, always chasing whatever problem catches my interest.

My interests span low-level systems, security tooling, applied ML, and distributed systems, with a quiet passion for environmental engineering. Distributed systems and machine learning is where most of my curiosity lives.

Outside of programming, I love learning new things, reading books, and exploring outside! Here's what I'm currently up to:

Working On: Thunderhead Playing: Stardew Valley Listening to: NFWMB - Hozier Reading: East of Eden - John Steinbeck Studying: TCP/IP Illustrated - Stevens

Thunderhead

A lightweight reverse proxy that scores the intent of incoming HTTP requests to detect and mitigate bot traffic — without relying on Cloudflare or third-party services.

Next.js

TypeScript

Redis

JavaScript

Nginx

> Passive behavioral scoring engine, no JS challenges or CAPTCHAs
> Scores requests 0-100 across signals: robots.txt violations, path crawling, request rate, suspicious headers, and content patterns
> Graduated responses: allow (< 40), tarpit with configurable delay (≥ 40), or block 403 (≥ 75)
> Structured JSON logging for all proxy decisions
> IP, CIDR, and user-agent allowlist support
> Config-driven: listen address, upstream URL, thresholds, and tarpit delay all configurable

TailwindCSS

PostgreSQL

Prisma

> Built a smooth, physics-based card deck with Framer Motion that triggers instant visual feedack as you drag
> Connected the Hardcover Books API to cycle through a user's selected genres without stalling or repeating data
> Designed a custom REST API proxy that tracks swiped book IDs to ensure users never see the same book twice
> Used Prisma and Neon PostgreSQL to save liked books and manage reading shelves instantaneously
> Integrated Clerk to handle secure email and Google logins, syncing user shelves across devices seamlessly

Lacunae

Accelerated MRI Reconstruction from Undersampled K-Space via U-Net

U-Net that reconstructs full MRI scans from 25% of the frequency data.

Python

pandas

PyTorch

> Center 8% of k-space columns always retained - low frequencies carry the bulk of image energy
> ~7.7M parameter U-Net with four encoder/decoder stages and transposed convolution upsampling
> Benchmarked on NYU fastMRI single-coil knee dataset (Zbontar et al., 2018)

Precursor

Cross-Asset Momentum Spillover from Commodities to Sector Equities via Granger Causality

Tests whether commodity price momentum predicts sector equity moves 1–5 days ahead.

Python

pandas

Jupyter

> Tests momentum spillover at lags k ∈ {1,2,3,4,5} trading days across 3,500+ daily observations
> DAG construction maps in/out-degree centrality to identify leading commodity indicators
> Backtest evaluates annualised Sharpe, max drawdown, and hit rate on an 80/20 train/test split
