Projects

Things I’ve been building.

A short, curated list. Each one solves a problem I actually had, or one I found interesting enough to take apart.

    ipne.me

    A fast IP and network lookup that answers browsers with a clean page and curl with plain text.

    Problem
    Checking your public IP, headers, or a domain's DNS usually means a page full of ads, or remembering which tool prints what.
    Approach
    A serverless service on Cloudflare's edge that reads the request, enriches it, and negotiates the response format, so the same URL works in a browser, in a terminal, and inside a script.

    The name is Turkish for “what’s my IP?”, and that’s the first thing it answers: curl ipne.me prints your address and nothing else. From there it goes deeper: request headers, user agent, location and network (ASN, ISP, Cloudflare colo), and lookups for any IP using RDAP, Team Cymru, and reverse DNS. 4.ipne.me and 6.ipne.me answer over IPv4 or IPv6 only, which is handy when you need to know which one you’re actually using.

    DNS records come over DoH (DNS over HTTPS), one record type at a time if you like. Any endpoint returns JSON when asked, with /json, ?format=json, or an Accept header.

    cfb.sh

    A developer toolbox on the edge — the small utilities I reach for every day, one hostname away.

    Problem
    The little tasks (a UUID, a hash, a DNS answer, sharing a snippet) shouldn't need a different website or a pile of local tools each time.
    Approach
    One Cloudflare Worker with a set of small endpoints that speak JSON, plain text, or HTML, plus a tiny POSIX shell CLI that needs nothing but curl.

    cfb.sh covers IP, DNS, and CIDR lookups, UUIDs, hashes, base64, timestamps, and request headers, plus a paste service and a URL shortener. Publishing is limited to an allowlist, so it stays a personal tool rather than becoming a public dumping ground.

    Responses follow the Accept header, and ?nocolor keeps plain-text output safe for scripts. The cfb command-line client is a single shell script with bash completion:

    curl -fsSL https://cfb.sh/install | sh

    VLMarket

    A multi-tenant marketplace where game and platform companies let their users trade virtual items safely, for real money.

    Problem
    Trading virtual items for money is easy to get subtly wrong, and every mistake is someone's balance or someone's item.
    Approach
    A ledger-minded backend where providers define and mint items, users trade through orders backed by a wallet, and every movement is auditable — no duplicated items, no lost or double-spent balance.

    VLMarket is a SaaS platform with three faces: an operator console, an admin panel for each provider, and a mobile-first marketplace for players. The interesting part is correctness. Money and items move together or not at all, and the system has to be able to prove it after the fact. It’s in active development; more when it ships.
