At Smartflow S.P. z o. o., I’m the sole developer and maintainer of a portfolio of over 20 client Angular applications, including legacy systems. I handle feature delivery, performance optimisation and code stability.

I’ve worked with back-end teams on NestJS APIs and built SSR architectures with Node.js/Express and Nginx. I also rewrote an internal framework from Angular 11 to Angular 20, then maintained and upgraded it through Angular 22.

At Unicard S.A., I co-created an access control system and migrated its production version from Angular 9 to 15. At Smartsoft, I built the company’s mobile application from scratch with Ionic and Capacitor, including interactive mapping.
