Backend infrastructure and automation engineering for teams that need things built right the first time — and want them running years from now without maintenance.
Theta42 is an independent infrastructure and backend engineering consultancy. We work with companies that have real problems — complex automation, unreliable systems, scaling challenges, and hard infrastructure questions that need senior-level judgment.
We don't sell complexity. Every engagement starts with understanding what actually needs to be done, and ends with a system that runs the way it should.
Founded on 20+ years of hands-on experience spanning enterprise-scale infrastructure management and modern AI systems, Theta42 brings the kind of depth you only get from someone who's seen it all break before.
"Good infrastructure is boring. It works on day one, and it works on day one thousand."
Simple, maintainable, correct. We favor proven technology over fashionable complexity — and we'll tell you when something doesn't need to be built at all.
We work best as a trusted technical partner — embedded in the problem, not parachuted in with a template. Deep engagements. Honest assessments.
When we build something, it's built to last. No vendor lock-in, no black boxes, no systems only we can maintain.
From greenfield platforms to legacy rescue operations, Theta42 handles the full spectrum of backend infrastructure and engineering work. Every engagement is scoped honestly and delivered without drama.
Server provisioning, configuration management, and infrastructure-as-code for teams managing dozens to hundreds of thousands of systems.
API design, service architecture, database modeling, and system design for applications that need to scale reliably under real-world load.
Docker, LXC, and Proxmox environments built for production. Custom container isolation, GPU passthrough, and multi-tenant workload management.
On-premises AI deployment using Ollama, vLLM, and custom inference stacks. Built for data sovereignty, low latency, and operational simplicity.
Deep Linux expertise spanning kernel configuration, storage systems, networking, and long-running daemon architecture for bare-metal and virtualized environments.
Architecture reviews, technology selection, team mentorship, and second opinions for engineering decisions with long-tail consequences.
Hands-on Linux, infrastructure, and backend engineering instruction for individuals and teams. Learn from someone who has operated systems at every scale — from homelab to enterprise.
Available for infrastructure consulting, backend architecture, and AI systems projects.
