Rust Systems & Agentic AI Engineer. Author of AllSource and AllFrame. Founder of Wolven Tech.
🌐 decebaldobrica.com for the long version. wolventech.io for engagement options.
I build Rust systems for HFT, HPC, prop trading, and 24/7 platforms where microseconds and state integrity matter, and I lead 0→1 AI-augmented product delivery. 15+ years shipping production code across fintech, identity, SaaS, and Web3:
- Shipped 1M+ lines of production Rust across four event-sourced platforms
- Cut infrastructure costs by 75% through serverless-first redesigns at Tellimer
- Cut memory 6–10× and release binary size 8× vs. equivalent TypeScript services
- Boosted developer productivity 3× via tech-stack consolidation, GenAI integration, and trunk-based delivery
- Led cross-functional teams of up to 25 engineers across fintech and Web3
Embedded Rust event store with an AI-ready product suite. WAL + Parquet columnar storage, zero-copy Arrow IPC, seven-day durability stress harness. Four-crate Edition-2024 workspace with an Elixir NIF bridge and 16+ feature flags separating community and enterprise editions.
🧰 AllFrame
The Composable Rust API Framework. Write your handler once, expose it via REST, GraphQL, and gRPC. Built-in HTTP/2 server, compile-time DI, CQRS, and MCP. TDD from day zero.

- 🔍 Technical Due Diligence: for VC partners and acquirers evaluating a Rust-heavy or event-sourced codebase. 48-hour turnaround available.
- 🧱 Fractional Rust Architect: embedded retainer, 1-3 days per week, 3-month minimum.
- 🚀 Platform Sprint: fixed-fee build of one concrete thing end to end (event-sourced service, MCP server, WASM migration, Tauri app).
- 🧭 Advisor: monthly architecture review and async sounding board.
I write about Rust systems design, event sourcing, agentic LLM workflows, and how small teams outbuild big ones. Read at decebaldobrica.com/blog.
