I build the live systems behind software that has to hold up.

Levii Soderberg — a self-taught software engineer focused on backend and systems: authoritative server logic, custom RPC protocols, state replication, and versioned persistence. Shipped as an AI desktop agent and 12 projects, several running live on real game communities.

Flagship systems

Read each two ways — what it does, and the engineering any systems team will recognize. Three run on live DayZ servers; one runs on my desktop.

JARVIS

A voice-activated AI assistant for Windows — say "Hey Jarvis", and Claude drives your PC through a registry of self-describing tools, then talks back. A plugin architecture where a new capability is one decorated function.

  • Python
  • Claude API
  • faster-whisper
  • openWakeWord
  • ElevenLabs
  • discord.py
What it does
Say "Hey Jarvis" and talk to your computer. A local wake-word engine listens, faster-whisper turns speech into text, Claude decides what to do, and ElevenLabs speaks the reply — out your speakers or into a Discord voice call. It opens apps, controls the system, answers web questions, sets timers, and drives a deep Destiny 2 integration: transfer and equip gear by voice, check the Nightfall, empty your postmaster. Every ability is a self-registering tool, so adding one is just dropping a file in.

Capabilities

What I bring to a team

Grouped so a studio and a generalist team can both find what they need.

Languages

What I write systems in.

  • Enforce Script
  • Python
  • TypeScript / JavaScript
  • SQL

Systems & Networking

The engineering that actually ships in my mods.

  • Authoritative client/server architecture
  • Custom RPC & message-protocol design
  • State replication & reconciliation
  • Serialization & versioned persistence
  • Eventual consistency & retry logic
  • Computational geometry / spatial queries
  • Finite-state machines
  • Performance & entity-lifecycle management

Patterns & Practice

How I keep large codebases sane.

  • Factory & polymorphic design
  • Service-registry / plugin architecture
  • Data-driven / config-first design
  • Open/closed extension & load-order layering
  • Event-driven architecture

Tools

The workbench.

  • Git
  • DayZ Tools / Workbench
  • JSON config pipelines
  • VS Code
  • Next.js / React
Currently deepening

Working through the Backend Engineering track on boot.dev to put formal foundations under the systems work I already ship — currently focused on Python, with HTTP servers, databases, and system design ahead.

Built framework-first, not one mod at a time

Beyond the flagships, a suite of server mods that share one foundation. For a studio like Bohemia this is the specialist signal; for everyone else it's the same discipline — clean architecture, reused across a product line.

The foundation

SyntactixCore

The shared framework the other mods plug into — a service registry with fanned-out lifecycle hooks, unified events, and standardized storage. Every mod below registers as a service and inherits its lifecycle, events, and storage from one place — the difference between a pile of scripts and a platform.

About

Hi, I'm Levii.

I'm a self-taught software engineer focused on backend and systems work. I learn by building real things end to end — most recently JARVIS, a voice-driven AI desktop agent with a plugin tool architecture, and a suite of 10+ server systems for DayZ that run live for real player communities.

Under the surface it's the same discipline wherever it ships: authoritative client/server architectures, custom RPC protocols, state replication, versioned persistence, and making unreliable third-party dependencies behave. I care about the invisible plumbing that keeps a system solid under real load.

I'm now looking for a role — backend, systems, or general software engineering — where I can bring that mindset to a team and keep leveling up alongside people who've done it longer.
