About me

I’m a Swiss-vetted Angular-focused frontend engineer and technical lead with 10 years in software development and with multiple satisfied clients across Switzerland, US, France or Germany. Bring me in if you need to upskill your Angular team, a hands-on technical lead, or an external interviewer.

I am a senior Angular consultant and frontend technical lead with 10 years of software delivery experience, including 8 years focused on Angular and the last 5 through my own freelance company.

I usually work on projects that need strong frontend ownership, not just extra implementation capacity. That can mean building a new Angular application properly from the start, modernizing an existing codebase, leading a difficult upgrade, improving architecture, or helping a team deliver more reliably.

I stay hands-on in the code, but I also take responsibility for the decisions around it. My work regularly includes frontend architecture, technical estimation, code reviews, refactoring, onboarding, mentoring, interviewing, and coordination across product, design, QA, backend, and delivery.

My main technical focus is Angular and modern frontend engineering. I work with Angular 2 and up to the latest version, TypeScript, JavaScript or browser APIs, and I have strong experience with Nx monorepos, micro-frontends, server-side rendering, internationalization, accessibility, SEO, or Workers.

I have worked on large and evolving frontend codebases where maintainability, upgradeability, and delivery speed matter as much as feature work.

On the UI side, I work with SCSS and libraries such as Tailwind CSS, DaisyUI, Angular Material, PrimeNG, Kendo UI or AG Grid. For state management and application structure, I have used NgRx, NGXS. I have also worked with Capacitor for mobile delivery and with browser and real-time technologies such as WebSockets, Server-Sent Events, Web Workers, and Service Workers.

I also cover the areas that usually make the difference in production: authentication, SEO, Core Web Vitals, Lighthouse-driven improvement work. I have worked with both cookie-based and JWT-based authorization, and I am used to building applications that need to be fast, stable, and practical to maintain.

My background also includes .NET, SQL Server, Azure, and API-heavy systems. I do not position myself as a backend contractor, but that experience helps me make better frontend decisions, work well with backend teams, and understand delivery beyond the UI layer.

My recent work has included leading the frontend build of a multi-tenant publishing CMS and two client applications from scratch, integrating a fintech application into a Module Federation micro-frontend setup, working on IoT-related delivery with high message volume, and delivering features in real-time environments. I have also supported teams through mentoring, training, interviews, and technical direction when they needed a stronger Angular lead.
