My Role

Founder & Principal Engineer (Wolven Tech)

⚠️ The Problem

A founder-mode team had a TypeScript services tier that couldn't hold the line under real load.

Cold starts stretched past half a second, memory per service sat at 30–50 MB per pod, and every new microservice meant another ~50 MB container shipped through the pipeline.

Infra spend scaled linearly with ambition.

The team had the domain expertise but no shared foundation — every service invented its own clean architecture, its own monorepo discipline, its own hot-reload story.

How do you cross the gap from promising prototype to production Rust without spending the next year rebuilding the same primitives four times?

💥 The Impact

Runtime: 30–50 MB per service, ~500 ms startup, ~50 MB release binaries.

Delivery: Every new service re-litigated the same architecture debates — layering, async runtime, logging, CI.

Cost: Cloud bills scaled with pod count, not with users.

Strategic: The team couldn't commit to Rust until it had a foundation — a template that encoded the right answers so engineers could focus on the domain, not the scaffolding.

Fix

Framework

Wolven Tech rust-v1 template: a production-ready monorepo with Rust API (Axum + Clean Architecture), Next.js 15 / React 19 marketing + app surfaces, 8 shared packages, and a Meta orchestrator (Tokio + Clap + Tmux) that runs the whole stack from one command.

⚡ Actions Taken

  • Replaced the TypeScript services tier with a Rust + Axum platform on a 4-layer clean architecture

  • Built the Meta orchestrator (Tokio async, Clap CLI, Tmux process management) — 2.7 MB binary, <50 ms startup, 3000+ log lines/sec

  • Shipped 1M+ lines of production Rust across event-sourced domains, WASM frontends, and desktop AI tooling

  • Wired Bacon hot-reload, Criterion benchmarks, clippy/workspace-lint discipline, and Edition 2024 across every crate

  • Unified Rust + JS orchestration (Cargo workspaces + Turborepo + Bun) under one meta command — language-agnostic process orchestration, real-time log streaming

  • Published monorepo-meta on crates.io and open-sourced the wolven-tech/rust-v1 template

🎯 Outcomes

  • Memory: 2–5 MB per service (down from 30–50 MB) — 6–10× reduction

  • Startup: <100 ms (down from ~500 ms) — 5× faster

  • Release binary: 6.3 MB (down from ~50 MB) — 8× smaller

  • 12 weeks from template pick-up to production deploy

  • Infrastructure cost trajectory cut up to 75% on Rust-replaced workloads

  • Reusable foundation: the next service is a meta new away, not a quarter of scaffolding

Future

💡 Key Lesson

Rust adoption succeeds when the foundation is shared. Teams don't fail at Rust because of the borrow checker — they fail because every service rebuilds architecture, tooling, and orchestration from scratch. A clean-architecture template with an orchestrator on top collapses that tax.

📋 Prescriptions

  • Start with a template, not a greenfield. Encode clean architecture, workspace lints, and Criterion benches once — reuse across every service

  • Invest in a polyglot orchestrator. Rust + JS monorepos need one command to rule them all — Meta, Nx, or Turborepo-with-Cargo

  • Benchmark before migrating. Memory, startup, and binary size are the three numbers that justify Rust to a CFO — measure them upfront

  • Adopt Edition 2024 + workspace lints from day one. Retrofitting is painful; baseline discipline is free
