chaos ? structure() : maintain();
I build systems that are meant to last. Not because they are complex, but because they are coherent. My work sits at the intersection of architecture, clarity, and quiet execution — where the solution is indistinguishable from the problem it solves.
About
Systems, by nature, want to drift. My role is to define the boundaries before they're needed — to build structure that holds without requiring maintenance through force. I think in primitives before I think in features.
My approach is methodical. I map dependencies before writing a line. I prefer fewer moving parts over clever abstractions. Optimization is not a pass at the end — it is a design constraint from the beginning.
I am not interested in impressive code. I am interested in code that does exactly what it is supposed to, no more.

Projects
Lattice
A distributed task scheduler with deterministic execution order. Designed for systems that cannot afford ambiguity.
Contour
A personal infrastructure layer for managing configuration across multiple machines. Zero cloud dependency.
Pale
A minimal API gateway with rate-limiting, request tracing, and structured logging. Built to be transparent.
Chronicle
An append-only event log with replay and snapshot support. For when the history of a system matters as much as its state.
Experience
Senior Backend Engineer
Vordex Systems
Designed and maintained the core data pipeline infrastructure. Reduced latency by 40% through architectural rework. Introduced deterministic testing protocols across three teams.
Infrastructure Engineer
Nullpoint Labs
Built and operated a multi-region deployment pipeline. Ownership over incident response, observability tooling, and internal developer platform.
Software Developer
Greymatter GmbH
Full-stack development on internal tools for a logistics platform. Migrated a legacy monolith to modular services without downtime.
Contact
I prefer direct communication. No forms, no scheduling links. If what you are building sounds interesting, reach out.
