I build production web systems with Next.js, TypeScript, and C#/.NET — and when I'm not doing that, I write operating systems, compilers, and databases in Rust from scratch.
Based in Salvador, Brazil · Available for remote work globally.
What sets me apart:
- Shipped a full x86_64 OS in Rust — bare metal, no Linux underneath, boots on real hardware
- Built a Redis-compatible in-memory database with lock-free concurrency (Rust + Tokio)
- Designed a systems programming language with an LLVM backend
- Deliver production web systems across full-stack (TypeScript, React, .NET)
Primary
Infrastructure & Tools
x86_64 OS written from scratch in Rust — no Linux underneath Preemptive scheduler (context switch inside timer ISR), heap allocator, hardware interrupt handling, damage-tracking compositor, and 3 native apps. Boots on real hardware and QEMU. 99 tests, ~98% logic coverage.

Systems programming language — fast as C++, safe as Rust Compiles to native binaries via LLVM 17. Hybrid ownership model (generational references + linear types) eliminates the borrow checker burden. Targets Linux and Windows.

Redis-compatible in-memory database in Rust Lock-free reads via DashMap sharding, async I/O on Tokio, AOF persistence, Pub/Sub, master-slave replication, and a TUI monitoring dashboard. Full RESP2 protocol support.

Full-stack web systems — TypeScript, React, Next.js, C#/.NET Production apps including financial dashboards, e-commerce, SEO-optimized sites, and REST/GraphQL APIs. Clean architecture, strong typing, performance-focused.
