wolven-techBook discovery
Rust-only technical advisory
now open for engagements

Rust systems, shipped with intent.

Wolven Tech is a one-person, Rust-only advisory practice, built for HFT, prop trading, HPC, and 24/7 platforms where microseconds and state integrity matter. Event-sourced backends, Tokio/Axum services, WASM modules, AI-agentic Rust. Quiet, cheap, correct.

Four ways we engage.

Pick the shape that matches your constraint. Every engagement starts with a 30-minute discovery call and a written proposal. No surprises, no vapor.

Fixed scope · 1–2 weeks

Technical Due Diligence

For VC partners and acquirers evaluating a Rust-heavy or event-sourced codebase. We assess workspace health, clippy discipline, async boundaries, test coverage, observability, operational maturity, and security hygiene.

Codebase auditArchitecture reviewRisk registerWritten report

48-hour turnaround available for time-sensitive deals.

Retainer · 1–3 days/week

Fractional Rust Architect

Embedded on your platform team as a senior-to-staff architect. Code reviews, architecture decisions, team mentoring, and hands-on work when the hot path needs to ship. Typical terms: 3-month minimum, monthly retainer.

ArchitectureCode reviewsMentoringHands-on

Best fit: seed to Series B teams with < 10 Rust engineers.

Fixed scope · 4–12 weeks

Platform Sprint

Design and build one concrete thing, end to end: an event-sourced service, an MCP server, a WASM migration, or a Tauri application. You get code, documentation, and a runbook. We show up, scope it, and ship it.

Event sourcingMCP / agentsWASMTauri

Fixed fee. Weekly demos. Source license on delivery.

Monthly · async

Advisor

A monthly architecture review and a staff-engineer sounding board. Async-first (written + Loom), with a 60-minute sync whenever you need one. Best for technical founders who want a second opinion they can trust.

How I work

Control the work. Keep the evidence.

Agent-assisted engineering moves quickly. Wolven Tech makes that speed reviewable: explicit scope, dependency-aware execution, configured gates, and evidence your team can inspect after handover.

Shipped tooling is not automatically active. Gates only count when configured for real paths and proven against a planted failure.

An industrial 3D workflow rig combining technical inspection, scoped platform delivery, verification, and retained improvements
diligence / delivery / verification / learning
  1. 01

    Discover

    Inspect code, constraints, operational history, and failure modes before prescribing.

  2. 02

    Specify

    Write acceptance criteria, boundaries, dependencies, and proof required for completion.

  3. 03

    Build

    Claim narrow work, ship visible slices, and keep architecture decisions close to code.

  4. 04

    Verify

    Test behavior and run configured gates against real paths, including hostile fixtures.

  5. 05

    Learn

    Compare bounded experiments, keep strict improvements, and retain failed evidence.

Engagement rhythm

From call to owned system

  1. 01

    Discovery (30 min)

    A short call. I ask the hard questions, you get a written proposal within 48 hours.

  2. 02

    Scope & contract

    Fixed fee, fixed outcome, fixed timeline. Retainers have a defined runway. No open-ended billing.

  3. 03

    Ship weekly

    Weekly demo, Loom recording, or PR. Whatever matches your team's rhythm. Progress is visible.

  4. 04

    Handover

    Code, docs, runbook, architecture notes. Your team owns what we built. We disappear on request.

Operated by

Decebal Dobrica.

Rust engineering leader with 15+ years of fintech, SaaS, and Web3 experience. Previously Technical Lead at Ebury, Software Architect at Tellimer, and fractional CTO across multiple founder-mode startups.

I started Wolven Tech because the teams I most want to help (small, ambitious, technical) keep asking the same questions: can Rust actually replace this TypeScript service? How do we event-source without drowning in ceremony? What does a staff-engineer-quality architecture review look like, in writing?

Wolven Tech is how I answer those questions professionally. One operator. Rust only. No subcontracting.
