If you’re a CTO, give me 90 seconds.
I was the only engineer of a Berlin B2B SaaS for a year. Before that: a .NET internship, a startup backend that was acquired at MVP stage, and a nationwide business I took online. Here is what you can hand me on day one.
What I can own
- Backend services
- REST APIs on Node.js / NestJS or ASP.NET Core, PostgreSQL schema design, background jobs.
- Product features
- End to end: talk to the user, model the data, build API and UI, ship, measure.
- Integrations
- Stripe, SendGrid, Lexware, analytics, LLM APIs — the unglamorous glue that makes money.
- Databases
- Multi-tenant PostgreSQL, migrations on live data, mapping legacy schemas instead of rewriting them.
- Authentication
- RBAC, JWT / httpOnly cookies, bcrypt, replacing an auth system in production.
- Deployment
- Linux, Docker, Nginx, TLS, PM2 / systemd, GitHub Actions. I have been on call for my own code.
- Technical prototypes
- Getting an idea in front of users in days, then deciding what deserves to be hardened.
What I enjoy
- Ownership of a problem, not a ticket
- Ambiguous problems that need shaping first
- Real products with real users
- Small and medium engineering teams
To save you an interview round
- I am mid-level, not a staff engineer. I have mostly worked alone — I want a team to learn from and review with.
- My deepest production depth is .NET/C# and Next.js full-stack; my TypeScript backend depth is growing fast.
- I integrate ML models into products. I am not an ML researcher.
- English B2 at work every day; German B1 and improving.
