Leading Swiss energy provider — real-time trading / decision-support cockpit for energy traders.
- Built a complex Angular + TypeScript + RxJS single-page cockpit for real-time trading decision support in a business-critical environment. Continuous market-data streams over WebSockets, operator-facing trader UI, strict performance and reliability requirements — directly comparable to a financial trading platform.
- Enterprise authentication integration (OIDC / OAuth2 patterns), reusable component library with SCSS styling, Reactive Forms, state management via RxJS and NgRx patterns. Automated unit testing with Jasmine and Karma, TDD discipline. Performance tuning of change-detection cycles and RxJS streams under high-frequency data load.

Summary
Senior freelance software engineer with 7+ years of experience across frontend, backend and DevOps, specialising in modern web applications for safety-adjacent and real-time domains — aerospace, energy trading, industrial robotics and banking. Angular has been my primary framework for close to ten years (from early Angular 2 to today's standalone components and signals), used at scale on the ALPIQ real-time energy-trading cockpit (2 years) with WebSocket-driven live updates and strict reliability requirements. I've also shipped Vue.js in production (Destinus hypersonic ground-control station, Axalp eVTOL operator tooling), React (Axalp eVTOL cockpit, 3+ years as primary architect), and Rust and Qt / QML / C++ for safety-critical and desktop modules.
I write Python daily on the backend (FastAPI, Pydantic, SQLAlchemy, pytest, asyncio) and build LLM and agentic systems using the Anthropic and OpenAI SDKs, MCP server design, and evaluation harnesses. Strong experience with enterprise authentication (OIDC / OAuth2 / Azure AD / MSAL) from Swiss banking work, REST and GraphQL APIs, WebSockets and real-time event protocols. At Axalp Technologies, I own the Git-based, containerised CI/CD pipelines — GitHub Actions workflows, Docker images, automated test and release gates, and OWASP Top 10 practices. Working knowledge of Kubernetes and Helm.
Founder of Alpine Wings GmbH (Switzerland, CHE-341.648.826, MWST registered) — the B2B entity through which I invoice Swiss, German and EU clients. French national (EU), Swiss resident, fluent in English and French, German B1. Based in Dübendorf, open to remote, hybrid or on-site engagements across DACH and remote-EMEA. DO-278 trained (CNS/ATM software integrity assurance, 2025), EASA A1/A2/A3 drone pilot.
