Brian Chen

Hi! I'm Brian, a 3rd year Engineering Undergraduate at the University of Cambridge with a strong focus on systems and mid-level programming (C++ & Rust). I build low-latency, resilient systems and enjoy protocol and systems design. Currently interested in internships and roles in systems or backend engineering.

Skills: Proficient in C++, Rust, Python, and TypeScript. Experience with Haskell and Julia. Knowledgeable in OOP, information theory, data structures, operating systems, and blockchain technology.

• MEng Engineering - Trinity College, University of Cambridge 2023-2027

High First Class Honours in Years 1 & 2.

Modules: Computer Architecture; Algorithms and Data Structures; Information Theory and Coding; Communications; Networking.

• Arm - GPU Software Engineer Intern Jul-Sep 2025

Contributed C++ and Python improvements to GPU driver tracing tooling, adding support for complex dynamic payloads while preserving backwards compatibility. Collaborated with other team members to deliver the feature improvements.



• Roku - Software Engineer Intern Jul-Sep 2024

Collaborated with two full-time engineers during the 12-week internship. Contributed to Python and TypeScript codebases, developed production middleware, and updated frontend based on UI/UX designs. Delivered a scalable solution to automate content generation and verification using large language models, impacting millions of users.

• Project Enviame - Scalable Full-Stack App with Rust + SSR Mar-May 2025

Full-stack app with Rust backend to prioritise message delivery with configurable email and calendar integration. MVP built and deployed in under a day, with QoL and scalability improvements afterwards. Formal writeup completed after project completion.



• Project RustyMoves - Custom UDP Protocol Framework Apr-Jul 2025

Designed a lightweight UDP-first protocol for real-time use cases, implemented in Rust with tokio. Focused on resilience to packet loss and minimal encoding overhead; a C++ client port is also in active development.



• Project Mini-RPC - Lightweight RPC / Serialisation Library in C++ Aug-Sep 2025

Implemented a near-zero-encoding-time protobuf-like serialisation layer using direct memory layouts and simple getter/setter APIs to make IPC/RPC fast and ergonomic for user-defined types.



• Project Openify - Large Language Models & Blockchain Integration Jul 2024

Rapid full-stack build (12 hours) integrating Polkadot and LLMs to handle transaction requests and account queries in natural language. Team placed first after a live demo and technical pitch.



• Project EasyPass - Machine Learning & Cloud Web App Feb 2024

Trained an open-source LLM on university exam questions and deployed a web backend to accept uploads and generate practice questions; integrated model inference into a cloud-backed web service.
