HALO Calculator

Fri, 12 Jun 2026 00:00:00 +0000

A lightweight, modular calculator built in pure Rust. It is designed to be portable, separating the mathematical engine from the GUI implementation, making it ready for future porting to the Halo OS kernel environment.

Features

Syntax Highlighting: Automatically detects file types (Rust, TOML, JS, HTML, etc.) and highlights syntax.
Smart Highlighting: Uses syntect for industry-standard parsing.
Zoom Control: Ctrl + and Ctrl - to adjust font size dynamically.
Status Bar: Real-time tracking of Cursor Position (Line/Col) and active Theme.
Theme Switcher: Toggle between Solarized, GitHub, Dracula, and more instantly.

HALO Editor

Why Adding Assembly Didn't Make My Quantum Simulator Faster

Fri, 12 Jun 2026 00:00:00 +0000

Overview

While developing a quantum circuit simulator in C++, I assumed that replacing part of the computation with hand-written assembly would improve performance. Assembly is often regarded as the fastest way to execute code because it provides direct control over the processor and avoids compiler abstractions.

To test this assumption, I implemented portions of the simulator using assembly and compared the results against the existing implementation built with C++ and the Eigen linear algebra library.

Zinex - external tiling layout generator

Fri, 12 Jun 2026 00:00:00 +0000

Written in Zig, Zinex connects directly to River using custom Wayland protocol interfaces, calculating window placements and managing client geometries dynamically in a frame-perfect manner.

Unlike traditional window managers that embed layout logic inside the core compositor, River delegates layout generation to external processes. Zinex acts as one of these processes, implementing layout algorithms and responding to display changes, window creations, and focus updates.

Case 000: Hello World

Thu, 11 Jun 2026 00:00:00 +0000

Welcome to the investigations log.

I will be using this space to document my technical debugging sessions, root-cause analyses, systems experiments, and learnings from real-world software and infrastructure issues.

HALO OS Prototype

Mon, 01 Jun 2026 00:00:00 +0000

Objective: Halo OS is a 64-bit UNIX-like operating system designed for deep educational value. It prioritises architectural clarity over commercial viability.
Language: x86 Assembly and C.
Architecture:
- Kernel: C11 (Higher Half, Monolithic)
- Userland: C++20 (planned)
- Boot: Multiboot2 -> Long Mode
- Memory: 4-level paging, bitmap PMM

5 Qubit Quantum Circuit Simulator

Fri, 15 May 2026 00:00:00 +0000

A high-performance quantum circuit simulator with a Qt-based graphical interface and a C++ backend for quantum gate simulation. This project provides both command-line and GUI tools for designing and simulating quantum circuits.

Language: C++ and Qt QML
Core Concepts: Complex vector spaces, matrix transformations, tensor products.

The project simulates quantum register actions locally on standard CPU hardware using high-efficiency vector calculations to inspect gate operations.

About Me

Mon, 01 Jan 0001 00:00:00 +0000

I am a software engineer with professional experience building, deploying, and maintaining software systems. My work has included frontend and backend development, database management, third-party service integration, cloud deployment, Linux-based environments, and production troubleshooting.

Rather than focusing exclusively on a single layer of the stack, I have worked across the lifecycle of modern applications—from user interfaces and backend services to databases, infrastructure, deployment pipelines, and operational support. This breadth of experience has given me an appreciation for how software systems function as a whole.
