Engineering model

We build the systems a business actually runs on.

FireXCore focuses on the load-bearing software behind real operations — backend platforms and vertical SaaS where money moves, decisions become records, and incorrect state has real consequences.

Backend systems
Vertical SaaS
Data integrity

The same engineer who scopes the system is accountable for how it is designed and shipped. Architecture, constraints and rejected trade-offs are written down so the system remains understandable as it grows.

Senior by default

The engineer who designs the system is the one who ships it, from schema to deploy.

Direct access

You work with the person building the system — not through an account-management layer.

What we build

Two flagship products in production, plus the open-source tools we ship along the way.

Vertical SaaS · Procurement

RMS — Request Management System

An enterprise procurement platform built as a modular monolith. A 13-state request workflow, server-computed authorization, append-only audit history, and idempotent award and purchase-order generation — so a retry or a lost connection never doubles an order.

  • React
  • PostgreSQL
  • Redis

Open Source · Digital Evidence

MailVault — Forensic Email Archiver

A read-only archiver for Gmail and IMAP that preserves raw EML and full MIME structure with SHA-256 integrity hashes. Built for eDiscovery, compliance, and litigation hold — archives are verifiable, never rewritten.

  • Open Source
  • eDiscovery
  • IMAP

Open-source tools

Smaller utilities we built for our own delivery pipeline and released publicly.

How We Build

Engineering standards, not slogans

The defaults on every system we ship — the reason our software behaves the same on a bad day as on a good one.

Backend decides, frontend renders
Authorization and available actions are computed server-side. The UI can never invent a capability the backend did not grant.
Audit-first, append-only
State changes are recorded as immutable events. History is fully reconstructable; nothing is silently overwritten or lost.
Idempotent & replay-safe
Operations are safe to retry. A dropped connection or a double-click never produces a double effect.
Durable outbox, not fire-and-forget
External side effects flow through a persistent outbox, so events are not lost when a process dies mid-flight.
Test-gated, statically analyzed
Delivery is blocked until the test suite and static analysis (PHPStan level 8) pass. Type errors do not reach production.
Documented, reversible decisions
Every architectural decision is written down with its trade-offs. The system stays understandable as it grows, and choices can be revisited — not archaeology.
