Known languages	GitHub Statistics	Languages used in public repositories

Hello - I'm Richard. I'm a Year 12 A-Level student who builds backend systems, programming tools, and infrastructure projects in my spare time.

I work primarily with Go, Lua/Luvit, and C, and I enjoy designing things close to the protocol layer - HTTP internals, routing engines, storage formats, and distributed infrastructure (the last one is my favourite).

Despite still being in school, I have independently built several production systems used by thousands of users, along with language tooling and low-level runtime components.

Backend systems, high-performance infrastructure, datastores, and protocol tooling. Some language design too, if you would like to include the Nue Programming Language.

I enjoy:

• writing character-by-character scanners/parsers
• designing high-performance HTTP stacks,
• implementing RFC-compliant protocols like SMTP, TOTP, and OAuth2,
• building storage engines and KV databases,
• real-world systems optimisation,
• Lua/Luvit internals, coroutines and event loops,
• and rewriting bottlenecks in C when necessary (although that might just be because I have outgrown Lua's purpose to the point where external intervention is required)

Of course, all of the above practically means nothing if I don't tell you about some real-world projects where I actually apply some theory.

• 3M+ stored documents
• 10K+ monthly users
• Low-overhead HTTP server through a heavy extension of coro-http Rubis now uses Rind in Go..
• Full telemetry with latency histograms, RPC counters, TTFB, and tag-based metrics
• MessagePack metadata pipeline with serialisation offloaded to C
• Burst-tested to ~12.5M requests without failure
• Used as the backend trust layer for sUNC's test result verification

• HTML compilation with component expansion
• Head segmentation and deterministic ordering (resource hints, metadata, scripts, styles)
• Sandboxed pre- and post-build Lua hooks for data generation and build-time logic
• Strict filesystem sandboxing for hooks (project / cache / generated / built scopes)
• Live development server with filesystem watching and debounced rebuilds
• Builds that are only a few milliseconds
• Zero runtime dependencies in the browser

Currently being rewritten in Go using Rind

• Full OAuth2 authorisation code flow
• Sessions, grants, and application management
• Strict CSRF protection and protection against replay attacks
• Passwordless login architecture
• TOTP 2FA implemented from RFC 6238 / RFC 4226 using OpenSSL's HMAC
• Custom SMTP client, "Letterbox", with persistent connections, MIME encoding, and connection pooling

There is a lot more in much more detail, however I would like to keep my GitHub README concise. For more information, request my CV by sending an email to hello@richy.lol.
