Work

What we have done

Representative experience behind COXSWAIN: an enterprise workplace-management SaaS platform (YAROOMS), our own products and contract work. Advisory engagements run under NDA and do not appear here.

Migration · Enterprise SaaS

From a mixed PHP and Node.js stack to Symfony 7, with behavioral parity

3 monthsfrom a mixed PHP and Node.js stack to Symfony 7

In short: A product used daily by large companies was moved to a modern foundation, piece by piece, without users noticing and without the team pausing delivery.
Stack: PHP 8, Symfony 7, Node.js, MySQL, Redis, SAML; Read the case study

Integrations · Microsoft 365

Outlook calendar sync at enterprise scale, without loops or notification storms

2-wayOutlook sync at enterprise scale, without loops or storms

In short: Outlook calendars and the platform stayed correctly in sync for thousands of users, without duplicate notifications and without manual fixes.
Stack: Microsoft Graph, Azure AD, Teams, PHP, Symfony Messenger; Read the case study

Cloud · Kubernetes

Clusters and databases moved between AWS, Azure and Google Cloud, in production

5 minof downtime moving live production from AWS to Azure

In short: Live production, database and Kubernetes cluster together, was moved from AWS to Azure in two weeks with about five minutes of downtime. Backups are verified automatically and the business no longer depends on a single vendor.
Stack: Kubernetes (EKS, AKS, GKE), GitHub Actions, MySQL, Cloudflare; Read the case study

AI in production

A ticket-to-pull-request pipeline, AI-assisted, with enforced quality gates

90%less human code review: people check business and product logic

In short: An AI reviewer reads every change before a person does, backed by tests and static checks. That cut human code review by about 90%: people review business and product logic, the AI proposes and people decide what goes into the product.
Stack: Claude Code, PHPStan, PHPUnit, React, GitHub Actions; Read the case study

Security

Hardening a multi-tenant platform: isolation, uploads, SSO, API keys

SSO + 2FAhardened across the platform

In short: When large customers asked how secure the platform is, the answer was backed by code, not by promises: isolation between customers, hardened sign-in, access keys with a lifecycle.
Stack: Symfony Security, SAML, OAuth, MySQL; Read the case study

Products and contract work

Things built from scratch

Our own products, from idea to production, plus contract work on products owned by others. They keep us honest: we know what it means to operate what you built.

A single-binary read-only MySQL browser for safe production access over an SSH bastion: SQL allowlist, encrypted credentials, two dependencies by design.
