Company

Small by choice. Serious by nature.

Wiesmann Software Engineering is a one-person studio — deliberately. Here's why that's good for your project.

The story

After years of building web and mobile products in teams of all sizes, I founded Wiesmann Software Engineering to work the way I believe great software gets made: one accountable expert, close to the client, from first idea to final deploy.

Based in Switzerland, I work with founders, small businesses and teams who need a senior engineer who also understands branding, SEO and the business side of shipping software.

How I work

Ownership

Your project is never passed down the line. I plan it, build it and stand behind it.

Clarity

Plain language, honest estimates, no jargon walls. You always know where things stand.

Quality

Fast, accessible, maintainable software. Boring technology where possible, innovation where it counts.

Partnership

I succeed when your product succeeds — so I'll challenge ideas that won't work and champion the ones that will.

One person — the honest math

The price advantage

No account managers, no office overhead, no agency margin stacked on top. You pay for senior work actually done — not for keeping a big team busy. That makes professional quality noticeably more affordable.

The honest trade-off

I'm usually deep in one or two client projects, so — emergencies aside — I'm not reachable all day, every day. In return, you'll always know exactly when I'm available and what I'm working on for you right now.

Have an idea? Let's make it real.
