Senior Software DeveloperAvailable for select work
I architect, secure, and scale complex systems.
For over ten years I've built and scaled complex back-end systems, hardened servers, and shipped software across the stack. Today I also design enterprise AI: custom model training, MCP integrations, and production LLM systems.

Engineering across the whole stack, with a bias for the parts that keep systems standing.
For over a decade I've built and run back-end systems: designing APIs, hardening servers, and taking complex architectures from an idea to production scale. I care about the unglamorous parts: the queue that never drops a message, the deploy that doesn't wake anyone at 3am.
My work spans back-end, systems, security, and increasingly applied AI. I move comfortably from a database schema to infrastructure to production LLM systems, which lets me own a system end to end rather than a single slice of it.

What I do
Backend & APIs
Service design, data modeling, and APIs built to stay predictable as they grow.
Systems & Infrastructure
Server administration, containers, and CI/CD: provisioned, hardened, and automated.
AI Solutions
Enterprise-grade custom AI: model training, MCP integrations, and production LLM systems.
Security
Server hardening and applied cyber-security research, from encryption to reverse engineering.
Data
Relational schema design and message queues tuned for throughput and integrity.
Mobile
Android and iOS applications, from prototype to store release.
