I'm Matthew Macchia, a former CTO and architect. I help founders, engineering teams, and technical leaders dig out of tech debt, stabilize fragile systems, and build platforms ready for scale. Let's put your codebase back on solid ground.
Let me handle the nerd herding!
The Problem
Deployments are fragile, new features take forever, and your team is stuck firefighting instead of building.
You don't need to start from scratch - you need structure, clarity, and experience to get your system back under control.
Start Here
Whether you need a quick diagnosis or ongoing leadership, I meet you where you are.
Start with a 20-minute call to identify your biggest challenge and see if we're a good fit.
Get immediate clarity with a 2-hour diagnostic session to identify critical risks and create an action plan.
A comprehensive 2-week engagement to produce a detailed roadmap for complex systems.
Ongoing embedded leadership with strategic guidance, mentoring, and roadmap planning (~5 hours/week).
Why Work With Me
When speed turns into fragility, I help teams diagnose, refactor, and rebuild with clarity and purpose.
I design architectures and processes that evolve with your business, reducing fragility while maintaining speed.
Get hands-on guidance from someone who has built and led engineering teams, not just advised them.
Cloud, event-driven systems, and microservices - the right tools, only when they fit your goals.

Selecting the right source of truth is crucial, especially in event sourcing. The decision between a State-Transition database and a Traditional Database, like PostgreSQL, is fundamental. This post explores the strengths and weaknesses of both, emphasizing PostgreSQL's role in the relational database domain.
Event Sourcing isn't a one-size-fits-all solution; it's a versatile approach that adapts to the unique demands of various industries. Explore some of the top usecases that drive businesses to first adopt event sourcing. And understand if it's right for your business.
In the world of software innovation, Event Sourcing stands out as a transformative force, turning data into an unchangeable narrative that shapes the core of your business. It's not just a technical choice; it's a strategic business decision for resilience, adaptability, and an unwavering audit trail. Event Sourcing isn't merely about managing data; it's about propelling your business into the future with a dynamic, trustworthy asset.
As an architectural pattern, event sourcing is a paradigm shift in how you think about data. In the event sourcing methodology, everything is an event that is to be persisted. Leading to the concept of immutability, Event Sourcing challenges the traditional CRUD model, turning events into first class citizens.
If your system is showing cracks and your team is losing momentum, let's talk. A short conversation can reveal what's really holding you back.
