01 · About

Systems thinking, production mindset.

I care about what happens under the hood — concurrency models, memory layout, cache behavior, backpressure — and turn that into backends that stay fast under load.

◈ Objective

Aspiring Backend & Systems Engineer with a deep focus on distributed systems, high concurrency, and low-latency network protocols. Passionate about leveraging systems programming (Rust, C/C++) to architect high-throughput data pipelines, network infrastructure, and resilient production backend services.

Distributed systemsLow-latencyHigh-throughput

✦ How I use AI in my workflow

  • Reverse engineering & R&D: parsing RFCs, hardware datasheets and low-level code with LLM assistance.
  • Automated QA & testing: synthesizing test suites, concurrency regression tests and property-based edge cases.

02 · Core skills

A backend engineer with a systems core.

From bare-metal C to async Rust to TypeScript APIs — one mental model: bytes, concurrency, failure modes.

03 · Experience

Where I've shipped.

Backend Developer Intern

VNet Joint Stock Company
  • Architected QUIC-Chat (vchat): E2EE messaging multiplexing control, chat, presence datagrams and file transfer over a single QUIC/UDP connection.
  • Stream-priority QoS + Threema-inspired blob streaming, >150 MB/s with zero head-of-line blocking.
  • Actor-based Tokio lifecycles, zero-copy Bytes slicing, backpressure, Double-Ratchet/X25519.

Independent builder & researcher

bamboo-core · SplitDebt · Dynomite STM32
  • Published a Rust crate to crates.io, built a group-expense backend with debt-simplification, and an STM32 game engine at 60 FPS.
  • Workflow: RFC/datasheet R&D with LLMs → systems design → property-based + concurrency regression tests.
04 · Projects & research

Things built to be fast.

Four systems I designed end-to-end — protocol, engine, embedded and API. Each one has a number I'm proud of.
