Summary
🤩
RockstarHenry Oswald is a seasoned software engineer and founder with 15 years of experience building and scaling web platforms, currently based in London. He founded ShareLaTeX—one of the first real-time collaborative LaTeX editors—which grew to millions of users and was acquired and merged with Overleaf, where he later led major infrastructure, scaling and incident response efforts. Henry is a full‑stack practitioner fluent in Node.js, TypeScript, Elixir/Phoenix, Docker, Kubernetes, Terraform and cloud platforms (GCP/AWS), with deep operational experience running large websocket fleets, Redis/Mongo clusters and CI/CD pipelines. More recently he combines hands‑on founding roles and personal open‑source projects—like an SSRF mitigation proxy, a CRDT backend (FireSync) and an AI recipe app—with parenting, keeping his technical curiosity sharp. Colleagues describe him as the kind of engineer who moves fluidly between product, ops and security, able to both ship features and harden systems at scale.
