Software engineer based in Lima, Peru 🇵🇪. I build products for web, mobile, and desktop, and tools that help me build the next one.
My work spans enterprise platforms with U.S. and international teams, and my own products under Niway. I work across the whole product: interfaces, backend services, local storage, deployment, and desktop releases.
cs19.dev — my projects, experience, and writing.
A desktop screen recorder that saves recordings as regular files in a folder you choose. Screen, system audio, microphone, and camera capture—with a local-first approach.
💬 Yui
A desktop assistant for live conversations. It transcribes on your Mac, keeps the session’s context, and answers when you ask. You can run answers locally or use your own AI provider key.
⚡ Laqi
A mock API server for building and testing frontends without waiting for a backend. Define responses, switch scenarios from a web panel, and let coding agents control mocks through MCP.
- 🚀 Product development: turning an idea into an app, from the first interface through backend services, authentication, and deployment.
- 🖥️ Desktop software: working with audio, video, local data, on-device AI, packaging, and updates.
- 🧩 Frontend engineering: building shared components, design systems, and interfaces inside larger platforms.
- 🔧 Developer tooling: creating mock servers, reusable project foundations, and workflows for working with coding agents.
✍️ I also write about the engineering behind my projects: the decisions, experiments, and problems I run into while building them.
