Dibbayajyoti Royfull-stack engineer, Rust systems builder

Three products anchor what I do publicly. Each solves a real problem I hit and could not find a clean answer to — the detailed writeups live on /work, and deeper topic pages cover Rust engineering, WebAssembly, AI engineering, Next.js SEO, and distributed systems.

Klinder-OSS — I kept stitching PostHog, LogRocket, and Customer.io together on every project, so I built one SDK that unifies event tracking, error-based session recording, and email trigger workflows in a single install.

AHTML — AI agents read websites slowly and expensively, so I built a sixteen-package npm scope (@ahtmljs/*) plus a Python SDK that lets any site publish an agent-readable, token-efficient snapshot — and emits MCP, OpenAPI, JSON-LD, llms.txt, RSL, and Markdown from one config.

Diffcore — I needed a JSON diff fast enough for large client–server state sync and found the popular libraries either slow or unmaintained, so I wrote the engine in Rust and ship it to npm as WebAssembly.

whatbroke — When a test or server dies in my terminal I kept losing the context — what changed since it last worked, which file is to blame — so I built a CLI that wraps the command, captures a redacted, git-anchored crash bundle, and hands a ranked suspect to my coding agent over MCP.

Roy UI — Every dashboard I built started by re-wiring TanStack Table or copy-pasting shadcn and bolting on filters, so I built one React component library that ships a batteries-included DataTable, a no-dependency date range picker, and an analog/digital time picker — installed, not copy-pasted, with zero config.

Fresco — Windows has Wallpaper Engine and macOS has Lively, but every Linux option was terminal-only or abandoned, so I built a proper GTK4 desktop app that sets any video, GIF, or image as a hardware-accelerated live wallpaper — install a .deb, pick media, done.
