About

I am a skilled Java Developer with strong communication and organizational abilities, analytical thinking, and a collaborative spirit. Currently, I work at iApps Technologies GmbH, where I develop innovative applications for a leading digital publishing company, focusing primarily on cloud migration. My expertise includes Java 8-11, Spring Boot, TypeScript, Node.js, AWS services (Step Functions, Lambda, ECS + Fargate, Batch, EFS, ECR, S3, CloudWatch), GraphQL, Elastic Search, Docker, Terraform, MySQL, and GitLab CI/CD integration. In my previous role at Orange, I developed and maintained business web applications for the telecommunications sector, working remotely and collaborating closely with international teams using technologies like Java 11, Spring Boot, TypeScript, React, Angular, and MongoDB. My earlier experience includes a position as a Junior Java Developer at Rant & Rave (Upland Software / Flairstech), where I developed large-scale software products and gained hands-on DevOps experience with AWS and continuous integration. Additionally, I attended comprehensive Java backend developer training at Connectis and completed a Nanodegree program in Android Basics with Java at Udacity. Prior to transitioning into software development, I worked as a Senior Specialist and Team Manager at ITB (Building Research Institute), preparing technical assessments and developing test programs for innovative construction products. I hold a Master’s degree in civil engineering from Warsaw University of Technology and completed an individual course of studies at Universidad Politécnica de Cartagena during the Erasmus Programme. I am fluent in Polish and English, with basic communication skills in Spanish and German.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
