Custom web app development

I build custom web apps, SaaS platforms and MVPs for companies and startups. I use Next.js, Spring Boot, Python and Google Cloud on hexagonal architecture, so the product ships fast, handles growth, and new features land in days rather than months.

FAQ

Which technologies do you use for web apps?

Next.js and React on the frontend; Spring Boot or Python (FastAPI) on the backend; PostgreSQL, MySQL or Firestore for data; and Google Cloud for infrastructure, with automated CI/CD.

Can you build my startup’s MVP?

Yes. We define the minimum scope that validates the business and I build it on an architecture that can grow, so it doesn’t need rewriting when users arrive.

Can you take over or improve an existing app?

Yes. I review the current code and infrastructure and propose an incremental improvement plan, without downtime or a big-bang rewrite.

Do you also handle maintenance?

Yes. I can take care of maintenance, monitoring and ongoing development once the app is in production.
