FULL-STACK DEVELOPER

EduardKrivanek

I design and build fast, dependable web applications end to end — Angular on the front, NestJS and Firebase behind — and I write about what I learn along the way.

01 · STACK

Full stack, end to end

One engineer across the whole system — from the first component to the last deploy.

01 — FRONTEND

Frontend

Angular · RxJS · TypeScript

I build Angular applications — client- and server-side rendered — that stay fast and maintainable as they grow. I work closely with product owners and keep quality high with unit tests.

  • Performance — lazy routing, tree shaking, defer blocks, change-detection tuning.
  • Architecture — clean boundaries in Nx monorepos with NgRx or Apollo Client.
  • Responsive — Angular Material and Tailwind, from desktop to mobile.
02 — BACKEND

Backend

NestJS · Firebase · MongoDB

I design REST and GraphQL APIs with NestJS and lean on Firebase for realtime data. I deploy to Google Cloud Platform, serve through Cloudflare, and monitor with Sentry, Kibana and Grafana.

  • APIs — REST and GraphQL with NestJS or Firebase.
  • Data — MongoDB and Firebase, with Prisma as the ORM.
  • Quality — Jest and Postman for tests, ESLint and Prettier for clean code.

04 · ABOUT

About me

I'm Eduard Krivanek, a Full Stack Developer focused on Angular, RxJS, Firebase and NestJS — building web applications that are as dependable as they are pleasant to use.

Over the last few years I've built financial dashboards that generate trading statistics, a YAML-driven UI generator, a ticket tracker for a bank, and a range of SaaS applications.

I love sharing what I learn — through blogging, conference talks and mentoring other developers. Away from the keyboard, I'm usually cycling or playing chess.

  • 5+ years of Angular

    From version 8 to today, keeping pace with every release.

  • Fast & efficient

    Performance-minded code and clean, maintainable practices.

  • Writer & speaker

    Sharing insights through blog posts and tech talks.

Senior Angular Interview Questions

Most of us spend our day-to-day work calling APIs, caching data, and displaying it to users. We do this for years, and it leads us to believe we've mastered frontend development, especially a framework like Angular.
