Frontend engineer focused on operational web and Android products, plus independent TypeScript tooling.
I build Angular, Ionic, and Capacitor interfaces, and develop libraries and developer tools in my own time.
This GitHub is a personal portfolio: the work below is independent, not client or employer source code.
Language- and framework-agnostic MCP tooling platform, implemented in TypeScript/Bun, with a CLI, plugins, tests, quality gates, and documentation.
TypeScript model tooling with validation integrations, security tests, benchmarks, and MCP support.
Published npm library and CLI for secrets, API keys, and environment-file encryption.
Professional Experience and Core Stack
- Operational applications: Angular interfaces for business workflows with complex, repeated-use interaction and long-lived product rules.
- Web and Android delivery: Ionic applications, Capacitor packaging, and UI work with TypeScript, RxJS, Angular Material, and Sass.
- Delivery practice: Docker-based development environments, Git/GitLab workflows, CI/CD jobs, and focused testing and maintenance work.
Personal work on this GitHub: repositories, packages, Docker images, and experiments built independently in my own time.
Professional work: separate, non-public operational web and Android work centered on Angular/RxJS, Ionic/Capacitor, Sass, Angular Material, Kotlin/Java Capacitor plugins, Docker, and GitLab CI/CD.

Personal TypeScript runtime and tooling
Bun is my regular runtime for scripts, test flows, and workspace tooling; not my primary production server platform.
