About me

Backend and systems developer with 5 years of programming experience. I help clients solve concrete technical problems: bug fixing, debugging, backend tasks, automation, API/integration work, Docker/Linux setup, CI/CD cleanup, and technical refactoring.

My main languages are Rust and Python. I can also adapt quickly to new stacks and work effectively in existing codebases when the task is clearly scoped.

My background includes building complex systems from scratch, including architecture, runtime logic, client-server communication, tooling, documentation, CI, and release workflows. I also have hands-on experience with ML/AI-related development, including reinforcement learning, NEAT, computer vision, and automation.

I work best on practical technical tasks that need real investigation and reliable delivery: finding root causes, fixing bugs, improving workflows, cleaning up code, and making systems easier to maintain.

CV / Résumé

Dec 2025 - Now

Founder / Lead Developer

Freven

Building a modular Rust platform from scratch: public SDK, Wasm plugins, client-server/runtime logic, tooling, docs, CI/release workflows, and deep debugging of architecture, content, and rendering issues.

Portfolio

Freven SDK

Public Rust SDK and contract layer for mods, experiences, and integrations. I worked on API/contracts, Wasm authoring surfaces, shared types, and maintainable boundaries between the public SDK and internal runtime.

Freven Reference Experience

Reference experience for Freven that demonstrates the public architecture in practice. I worked on world/content structure, gameplay-facing systems, integration paths, and keeping the experience aligned with the platform model.

Freven DevKit

Developer toolkit for a modular Rust platform: launcher, client/server setup, templates, documentation, and issue tracking. I worked on tooling, developer workflows, docs, and reproducible local environments.

Freven Engine

Rust-based engine/platform built from scratch with focus on architecture, runtime systems, client-server logic, debugging, tooling, documentation, and clean modular boundaries for long-term maintainability.
