Flagship builds
Small enough to learn from, serious enough to prove the idea. Systems, AI, enterprise tools, and creative experiments — all in active development.
A beginner-friendly hobby OS in Rust.
Boots a no_std x86_64 kernel in QEMU, renders a framebuffer graphics console, logs to serial, runs a tiny era-themed shell, handles CPU exceptions and timer interrupts, has early memory management, an in-memory filesystem, and built-in apps like notes, calc, and sysinfo.
Next.js + Supabase enterprise finance platform.
Role-based workspaces, dense accountant-friendly UX, service-layer architecture, AP/AR/GL/cash/reporting/admin workspaces, saved views, notifications, audit logs, and Supabase-backed runtime datasets.
Premium multi-assistant AI workspace.
Built with Next.js, TypeScript, Tailwind, shadcn/ui, Supabase, and OpenRouter. Assistant families like Nova, Velora, Axiom, Forge, Pulse, and Prism, tier-aware model routing, text/image flows, prompt precheck, assistant recommendations, working notes during streaming, memory, usage tracking, plan requests, and admin dashboards.
Calendar-style productivity app.
A life sorting / calendar-style productivity app synced from v0, built with TypeScript and a Next.js-style app structure.
Webcam-to-ASCII visual experiment.
A TypeScript/Vite webcam-to-ASCII visual experiment that renders the camera feed as live characters in the browser.
Site map
Different parts of the site serve different purposes. Start wherever your curiosity fits.
Polished builds, shipped products, active experiments, and earlier work.
Interactive demos, visual experiments, terminal toys, and OS explainers.
Build logs, debugging notes, architecture sketches, and experiments in progress.
Technical system designs for platforms, AI workspaces, cloud tools, and enterprise software.
Exploratory papers, technical comparisons, and long-form research notes.
What I'm currently building, learning, exploring, and shipping.
What is active, next, later, paused, and shipped.
My developer journey from early learning builds to systems, AI, and enterprise tools.
Study maps across OS development, Rust, AI infrastructure, graphics, enterprise software, and product.
Downloadable notes, PDFs, diagrams, prompt packs, and technical resources.
Latest from the workbench
Why building a small OS is a good way to understand bootloaders, memory, interrupts, and how software starts running.
A field note on why QEMU makes OS dev approachable, why serial logs matter, and why a blank screen can have many causes.
Notes on why writing pixels directly to framebuffer memory makes OS development feel visual for the first time.
Dense UI is not automatically bad. Finance tools need speed, filters, drilldowns, saved views, exports, and auditability.
