01 — TX Back Office

RWA issuance platform — Tech Manager — live at tx.org

TX Back Office is a platform where companies register, verify via KYC, and issue Real World Assets on-chain. As Tech Manager, I led backend architecture, owned smart contract development, and coordinated delivery across a multi-service system from May 2025 through April 2026. The engagement concluded with a formal knowledge transfer document.

Smart Contracts

CosmWasm broker contract: order flows, partial execution, margin trading, mint/burn of USD-backed assets, oracle integration. Broker extension added in final month. Regulations documentation authored.

Backend Services

Order Management, Asset Management, Smart Contract Management, KYC/Account, Wallet Middleware, Organization service, Admin services, User Assets gRPC. All built on Go + gRPC.

Handoff

Engagement closed with broker extension support and a knowledge transfer document in April 2026. Repos left in clean state — deploy scripts, env configs, and documentation updated through the final commit.

The problem space

Issuing Real World Assets on a blockchain involves a tangle of moving parts: KYC verification, smart contract instantiation per organization, order management across multiple asset classes, wallet custody, crowdfunding flows, and margin trading — all needing to compose cleanly and fail gracefully.

What got built

A modular microservice platform: broker contract in CosmWasm handling the full order lifecycle, 7+ gRPC backend services in Go, KYC integration via Persona webhooks, asset distribution and crowdfund flows, wallet middleware with margin trading support, and a complete admin frontend. Handed off with documentation.

02 — Pulsara
