What I do

Backend engineering

APIs and background jobs that are secure, idempotent and observable.

In plain words

The backend is the part of a website or app that you never see. It looks after accounts, orders, payments and messages, and keeps them safe. I build it so it stays secure, keeps working when many people use it at once, and can grow with your business.

What this involves

I build REST APIs and the machinery behind them: authentication, role-based access, job queues, streaming responses and third-party integrations. The API I lead today has more than fifty endpoints and isolates each company's data.

  • NestJS
  • Node.js
  • PostgreSQL
  • Prisma
  • JWT and RBAC
  • SSE streaming

    An MVP is the smallest version of your idea that real people can use. It shows you whether the idea works before you build all of it.

Questions people ask

›Do I need to understand the technology?

No. I explain things in plain language and will stop and explain again if something is not clear.

›Can we work together if I am in another country?

Yes. I work with clients anywhere, remotely, by message, email and video call, and I am comfortable working across time zones.

›What happens in the free consultation?

You tell me what you want to achieve, you ask your questions, and I tell you honestly what I think and what the next step could be. There is no obligation.

›Can you work on something that already exists?

Yes. I can fix, speed up or take over a website or app that someone else built. We would start by looking at what you have.

Tell me what you want to build or fix
