I build low-latency C++ trading systems and work across the full systematic-trading stack — signal research, backtesting, execution, and real-time monitoring — with a statistician's eye for data.
I'm a quant developer and statistician (M.Stat, Indian Statistical Institute) with production HFT experience building low-latency C++ trading systems. I'm comfortable across the full systematic-trading stack — from microstructure signal research and tick-level backtesting to execution and real-time monitoring.
Outside of trading, I like building things from scratch: browser games, VS Code extensions, offline file-transfer protocols, and native handheld console apps. I'm also into competitive programming, reverse engineering, and the occasional wargame.
I'm constantly learning and enjoy the craft of turning hard, low-level problems into clean, working systems.

A one-way optical file-transfer protocol: stream arbitrary binary data from a Retina display to a phone camera — no networking, Bluetooth, or reverse channel. Built on a rateless LT fountain code, layered Reed–Solomon FEC, and a calibrated physical layer. Pure C++23 encoder, byte-identical recovery.
Open .zst compressed files directly in VS Code, no terminal needed. A streaming page-by-page viewer with flat memory usage on multi-GB files, Rainbow-CSV / JSON highlighting, full-file search, go-to-line/page, and an in-place edit-and-recompress mode.
A collection of native games and apps for the R36 Ultra handheld console (ArkOS 4.4), built from scratch in C++ with SDL2 — Snake, Pong, Wordle, Sudoku, mazes, sliding puzzles, water sort, plus utilities like a calculator, terminal, video player, and gamepad mapper.
A Chrome extension paired with a Flask backend that auto-solves an online maze game. The backend tracks game state and drives carefully engineered API calls to the game server to reconstruct and complete the maze automatically.
An algorithmic-trading toolkit for the IMC Prosperity competition: an event-driven Python backtester, a faster Rust port, and an interactive dashboard for PnL and position analysis on the strategies.
A git-like local data-storage utility for managing large numbers of log files in compressed form, with easy retrieval — built to keep tick-level and experiment logs organised and space-efficient.
A wireless small-file-transfer wrapper that shares files and generates short, memorable links for them that stay live for a few hours — friction-free sharing without accounts or apps.
Research on multivariate generalisations of the Wald–Wolfowitz and Smirnov two-sample tests via minimum spanning trees and shortest Hamiltonian paths, with parallelised computation and an interactive Plotly/Dash dashboard.
Notes from the reverse-engineering rabbit hole — writeups from the OverTheWire wargames and other low-level puzzles I've been chipping away at.
Walking through Utumno level by level — mapping the stack and environment layout with a homemade child probe, then hand-writing a NOP-sled + shellcode payload and smuggling it in through execve's environment to overwrite a saved return address.
The Maze levels turn on library search order and symbol resolution. I override puts with my own version that quietly reads the next level's password file — a clean, self-contained look at how the dynamic linker can be turned against a setuid binary.
A short crackme writeup — following an xref from the success string in IDA to the compare routine, then untangling the XXXXX-XXXX-XXX format check and the three per-segment XOR keys to recover a valid key by hand.
