Hello! I am a software engineer with a Bachelor's degree in Computer Science, more than 10 years of experience and 10 professional certifications earned after a lot of study and hard work.

Up to anything: Backend, frontend, blockchain, compilers, DevOps, embedded or mobile. Bonus point if there is a little bit of Rust involved.

If you are curious my greatest project is WTX, a fast WebSocket framework and Database client that gave me a lot of insights about performance and code architecture. See https://github.com/c410-f3r/wtx.

Show HN: New TLS 1.3 (RFC-8446) implementation written in Rust

CaioFer — Fri, 10 Jul 2026 14:03:58 +0000

Announcing the new release of the WTX project.

After ~2 years of development, the TLS feature is finally in an usable state where clients can connect to popular sites and servers can negotiate basic handshakes.

On its own the RFC-8446 specification is huge, complex and prone to errors, not to mention other associated features like ECH or DTLS. That is why features like PSK, HRR and 0-RTT are still not supported but they will probably be added in the future.
