Hey,
I'm James Tsetsekas
Web & Digital Experience Developer at Great Plains Communications (now Rightfiber) and Product Engineer at Conduit. I build customer-facing React experiences and open-source Nostr commerce with Bitcoin and Lightning.
About Me
I'm a Web & Digital Experience Developer at Great Plains Communications (now Rightfiber), where I build React applications for customer-facing digital experiences.
I also work as a Product Engineer at Conduit, an open-source decentralized commerce platform built on Nostr with Bitcoin and Lightning payments. My Conduit work spans React and TypeScript product features, protocol-aware workflows, encrypted messaging, privacy-focused checkout, and payment flows.
My independent work includes Bitcoin market analytics, Lightning wallet tools, digital-securities settlement prototypes, AI-assisted developer tools, and technical writing. I founded the Jersey City Bitcoin Meetup and Socratic Seminar, where I organize practical discussions around Bitcoin, Lightning, privacy, and protocol development. Outside of code, I ski and self-host more than I probably should.

Codex Reset Guard — Windows Tray App
An independent, portable Windows tray app that redeems your selected, existing banked Codex resets at a chosen usage threshold. Automatic resets are off by default. Choose the earliest-expiring allowed credit, set a finite reset allowance, and keep a reserve. Built in C# with persistent request recovery through the official Codex app-server.
nos2x Auto Approver — Nostr QA Signer
Chromium-only nos2x fork built for automated Nostr development and QA. It adds explicit host allowlists for unattended NIP-07 operations while retaining standard approval prompts on every other host, and is designed only for disposable test identities.
Digital Securities Settlement Engine
Atomic Delivery vs. Payment (DvP) settlement engine for tokenized securities on Ethereum, inspired by DTCC's Project Ion.

Solidity 0.8.20, Hardhat, OpenZeppelin v5, ethers.js v6.
Bond Settlement on DAML
Multi-party bond issuance, trade matching, and atomic DvP settlement built on Canton/DAML. Models the full DTCC/NSCC/DTC clearing workflow with CCP novation, custodian banks, trade reporting, and regulatory observation. DAML's signatory/observer model enforces multi-party consent at every state change.
