01 / Selected work

Real systems.
Considered decisions.

The problem, the engineering decisions, and what changed in production.

All projects

02 / How I can help

From application code.
To production.

Software, delivery, and reliability are connected. My experience spans all three.

Software & architecture

Understand the system.

Backend development is the foundation of my work. I build APIs and integrations, understand application behavior, and trace problems across service boundaries.

Multi-tenant backends · APIs · Integration design

DevOps & automation

Make delivery repeatable.

I connect development to production through automated pipelines, versioned infrastructure, and deployments with a clear path to rollback.

CI/CD · GitOps · Infrastructure as code

Reliability & observability

Keep production dependable.

I work on availability, useful telemetry, and incident response. The aim is to understand failures, reduce operational noise, and make recovery easier.

Metrics & logs · Alerting · Incident diagnosis

03 / Background & experience

A software foundation.
A reliability mindset.

I started in software engineering, building services, integrations, and the delivery pipelines behind them. My work grew into SRE and DevOps: understanding how those systems behave, fail, and recover in production.

That foundation stays with me. I approach infrastructure with a developer's understanding of the application, and development with an operator's understanding of what happens after deployment.

What are you
working on?

A system that needs to be more reliable, a delivery process to improve, or a role where software and operations meet. I'd like to hear about it.
