Eerie Sisu is a Senior Software Engineer with nine years of full‑stack experience building and scaling web and mobile products, known for production‑grade TypeScript and React as well as performant native UIs. They have shipped real‑time media features and GraphQL/REST APIs for high‑impact apps—from a group voice call platform with HLS streaming to logistics systems that run offline and peer‑to‑peer sync. Comfortable owning end‑to‑end delivery, Eerie configures cloud deployment pipelines, DNS, and CI/CD while managing client expectations as an independent contractor. They combine pragmatic refactors and stress testing to improve performance, accessibility, and testability in legacy codebases. Based in Zatwarnica, they bring a hands‑on mindset honed at startups and consumer companies and a quirky open‑source persona (self‑described “Pathetic Cleanroom contributor”) that hints at curiosity beyond formal roles.
