Nicolas Boyer is a full-stack software engineer with five years of experience modernizing legacy systems and building performant web applications using Java (Spring Boot), Angular, TypeScript, Python and C++. He has worked on large-scale mainframe-to-microservices migrations at AWS and contributed low-level, performance-critical code to widely used open-source projects like simdjson and simdutf, adding SIMD-optimized transcoding, benchmarks and fuzzing utilities. Based in Greater Montreal, he blends practical product-focused development with deep systems expertise—comfortable both validating business logic in modernized apps and optimizing character-encoding/parsing routines that power Node.js, Chromium and other major runtimes. A fast learner and reliable collaborator, he repeatedly takes on challenging integrations and performance work that sits at the intersection of application and systems programming.

simdjson/simdjson

May 2021 - Sep 2021

Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks

Role in this project:

Back-end Developer

Contributions:24 reviews, 18 commits, 24 PRs in 3 months

Contributions summary:Nicolas primarily contributed to the `simdjson/simdjson` repository by adding implementations of JSON parsing using libraries like RapidJSON and nlohmann_json. Their work involved creating and integrating SAX-based parsers for benchmark testing in the `kostya`, `distinct_user_id`, `find_tweet`, `large_random` and `top_tweet` benchmarks. The user also updated the `bench_ondemand.cpp` to include the newly added parsers and also worked on `partial_tweets` benchmark. Furthermore, the user added various improvements, including the inclusion of `JSON Pointer` support and the implementation of `document_stream` functionality within the `ondemand` module.
