Projects

What I build in my own time. Most of it started as something I needed, and a lot of it is for Nepal.

1. 

   The NepDate family

   NepDate

   Bikram Sambat, the Nepali calendar, wherever software needs it. It began as a C# library and grew into one dataset and one spec, so every language and every app gives the same day for the same date.

   • Libraries for 14 languages

     1.0 release candidate

     I wrote the ports for 13 languages from the shared spec and test vectors, and co-maintain the C# original by Raju Prasai. Each one converts, formats and parses dates, with a second package for tithi, holidays and events.

     one date, three of the languages

     // TypeScript
     NepaliDate.of(2081, 4, 15).long();
     # Python
     NepaliDate(2081, 4, 15).long()
     // Kotlin
     NepaliDate.of(2081, 4, 15).toLongString()
     // each one answers: Shrawan 15, 2081

   • Patro on the web

     Live

     The Nepali calendar in a browser: a page for every month from BS 1901 to 2199, with tithi, holidays and events, in Nepali and English, and each year’s public holidays as a calendar file.

   • MitiBar

     v1.1.0 for Windows, macOS and Linux

     The Nepali date on your desktop: on the tray or menu bar of every system, in a bar above the Windows taskbar, with the whole month one click away. Small, fast and offline.

     • Rust

   • NepDate Patro for Android

     Closed beta

     A calendar app with nine home screen widgets, a festival list, search and a date converter. No ads, no account and no network permission.

     • Kotlin
     • Jetpack Compose

     Source

     

   • NepDate Patro for iPhone

     In progress

     The same calendar in SwiftUI, with widgets for the home screen, Lock Screen and StandBy. Most of the code is merged and tested in CI; device testing comes next.

   Sluice

   v0.1.0 released, working toward 1.0

   Send big files straight from one computer to another. The sender prints a one-line ticket, the receiver dials in over QUIC, and nothing is stored in between.

   • A file, a folder, several paths or standard input
   • Every block checked against its BLAKE3 root before it is written
   • A dropped transfer resumes from what it already verified
   • Live mode: read a file while it is still being written
   • Inspect a ticket before fetching a byte
   • Fetch part of a folder by glob, or one byte range of a file
   • Queue several tickets, with priorities and retry
   • Rate caps, ticket expiry, and tickets shared with a set number of receivers
   • Direct first: LAN discovery, hole punching and port mapping
   • A relay only if you run one, and it ships closed
   • TLS 1.3 with a post-quantum key exchange preferred
   • No account, no hosted storage, no telemetry
   • JSON output and stable exit codes for scripts
   • Linux, macOS and Windows, by Homebrew, Scoop or Docker

   Curioflux

   In daily use, open source later

   A self-hosted knowledge base for what you save. Send a link from your phone; it archives the page, links it to what you saved before, and answers you and your coding agents.

   • Capture from Telegram, the web app, a phone share sheet, a browser extension or email
   • Bookmarks pulled in from Mastodon, Bluesky and Discord
   • Each page archived as raw HTML and as Markdown; PDFs as text
   • A list of links is split into entries and each one fetched
   • Topics, entities and typed relations, each with the quote that supports it
   • Full-text search in SQLite, with no embeddings to run
   • Eight read-only MCP tools for Claude Code and Codex
   • Notes written into an Obsidian vault kept in Git
   • Private text stays local; only public pages reach the AI provider
   • Any OpenAI-compatible provider, DeepSeek by default
   • Sign-in by Google allowlist or passkey
   • Nightly backup to R2, with a restore drill

   • DHM warnings, road closures and weather models checked every 30 minutes
   • Official sources always outrank a model

   • A message only when the answer changes, with quiet hours
