VD Valentin Dosimont Gaming, AI, blockchain
Gaming x AI x blockchain

Systems that feel fast, ship cleanly, and stand up in public.

I build infrastructure and developer tooling at the point where gaming, AI, and blockchain start behaving like real products. My work spans Rust services, TypeScript platforms, open source libraries, terminal UX, and the operational details that keep ambitious systems reliable.

marathon

A distributed Claude Code runner that executes tasks inside isolated Firecracker VMs.

View repo
Context
Agentic development only becomes credible at scale when execution is isolated, schedulable, and measurable.
Build
Built an orchestrator, node operator, and VM agent architecture for running coding workloads across sandboxed machines.
Signal
Demonstrates systems depth across AI orchestration, virtualization, metering, and low-level runtime concerns.

claudeswarm

Automated ticket-to-PR orchestration with sandboxed execution and multi-provider issue sync.

View repo
Context
AI-assisted engineering workflows need more than prompts; they need queues, state machines, review boundaries, and observability.
Build
Designed a multi-service platform with API, dashboard, worker, PostgreSQL, pg-boss, and PR automation.
Signal
Shows product thinking around AI operations, developer workflows, and reliable automation loops.

sqlv

A keyboard-first SQLite explorer for the terminal, built with Ratatui.

View repo
Context
Database inspection in the terminal is still clumsy for engineers who want speed, multiple connections, and serious keyboard ergonomics.
Build
Implemented a full-screen TUI with schema browsing, query tabs, autocomplete, inline editing, and Vim-style navigation.
Signal
Highlights Rust product craftsmanship and a strong eye for practical developer experience.

Freelance

Developer

Built client work across stacks while establishing the engineering fundamentals that still shape how I ship today.

  • Freelance
  • Full Stack
Footprint

Tools, habits, and operating style.

The stack is broad, but the throughline is always the same: practical systems, sharp feedback loops, and maintainable code.

Core stack

  • Rust
  • TypeScript
  • Go
  • JavaScript
  • Kubernetes
  • Ansible
  • Terraform
  • Microservices
  • jj-vcs
  • GitHub
  • Vim
  • OpenCode

What companies get

Someone who can move from product shaping to infra details, from open source maintenance to production incident prevention.

Where this fits

Gaming platforms, AI-native products, blockchain infrastructure teams, or any company that needs technical depth without theatrics.
