Senior Web Engineer

Anton Schmidt

I'm a senior frontend engineer with a passion for clean, maintainable and performant code. Eight-plus years turning demanding briefs from Porsche, Eurowings and others into polished, well-tested products, and I love mentoring the people I build them with.

Experience

8+ years as a web engineer, from rapid prototypes to production design systems for demanding brands.

Mentoring & sharing

I promote knowledge transfer and open-source software. Coaching frontend developers is the part of the job I enjoy most.

AI in the workflow

Modern LLM tooling (Claude, Cursor, MCP) used where it genuinely speeds delivery, always behind solid quality gates.

Background

A little context.

I've been into tech for as long as I can remember and turned that into a career on the web. My work sits mostly in design systems, scalable frontend applications and data-heavy tools, the kind of projects where clean architecture and real performance actually matter. Outside work I tinker with hardware and 3D printing, and every now and then I write about it.

Languages

German (native), English (C2), Russian (native).

Education

M.Sc. International Media and Computing, HTW Berlin. Final grade 1.25, with honours.

Let's talk

I'm a senior frontend engineer based in Germany, working remotely, and open to interesting projects, freelance or permanent. I'm most useful on design systems, complex data-heavy UIs and teams that care about quality and want someone to mentor along the way. Email is the quickest way to reach me.
