$ echo "Hello, world!"

System Software Engineer — AWS ElastiCache.
Rust, C, Node.js. I design and ship fast, reliable data systems and the client tooling around them. Maintainer in the Valkey ecosystem (incl. Valkey GLIDE).

---

What I do

• Valkey GLIDE (maintainer/contributor). Multi‑language client (Rust core; Node/Java/Python/Go bindings) focused on reliability, HA, and performance.
  Repo: https://github.com/valkey-io/valkey-glide
• Ecosystem enablement. Adapters, migration paths, and tooling that make Valkey adoption straightforward and safe at scale.
• Performance engineering. Resource management, IO/memory‑centric software, and pragmatic APIs that map cleanly to underlying hardware/OS.

Now

Hands‑on systems learning by building and benchmarking:

• Storage Engine. Hash/B+ tree indexing, page/buffer manager, WAL, and vectorized execution.
  Repo: https://github.com/avifenesh/storage-engine
• Multithreading Workshop (C/pthreads). Exercises on futex‑backed primitives, cache effects, atomics/memory ordering, perf/TSan workflows.
  Repo: https://github.com/avifenesh/multithreading-workshop
