Messages that settle trades.
At ZagTrader I build the gateway between markets, custodians and banks — routing, validating and archiving SWIFT & FIX messages across the post-trade lifecycle.

ZagTrader
Software EngineerPost-trade and market-data infrastructure for a capital-markets platform.
- Built the Swift Suite — Engine, Bridge & Monitor — an end-to-end SWIFT securities-settlement platform processing ISO 15022 MT540–MT548 and MT564 with a maker-checker approval workflow.
- Engineered the Swift Engine: an async task pipeline (reader → validator → builder → SWIFT validator → sender → archiver) that builds MT messages from SQL Server templates and validates them with Prowide via IKVM (Java↔.NET interop).
- Built the Swift Bridge gateway relaying messages between the engine (TCP / MessagePack) and external operators — Fineksus (SOAP/CoreWCF), Tadawul·Edaa (SoupBinTCP) and SFTP — with secrets in Azure Key Vault.
- Created the Swift Monitor dashboard (React 19 + TypeScript, real-time SignalR) with status monitoring, audit trail, template versioning/diff, and OTP/2FA + rate-limited auth.
- Built ZagKeyGenWeb (hardware-bound licensing: TripleDES, HMAC-SHA256, AES-256/PBKDF2) and FixPortal (ASP.NET Core, EF Core, React, JWT) — a FIX portal with a 150+ tag dictionary, per-market rules and message diffing.
- Added a CMC Markets FX reader (FIX SecurityList + level-1 bid/ask) to the market-data framework and an OKX exchange connector (WebSocket v5, HMAC-signed) for live/demo order routing.
