About Tomasz

I am an integration expert with a huge experience of over 15 years of hands-on work in integration and the job description fits what I like the most – using integration to drive the business.
I am open minded, and I learn quickly, so I easily enter new environments and I understand the dependencies between systems to see the big picture of how they work together to fulfill their role.
I take to integration like a duck to water. I have done many projects, so integration does not have any secrets to me. I use various protocols (REST, Web Service, API, Database access) and security standards (OAuth, JWT, Web Service Security). I write JavaScript code and java components to connect to various systems. If I had problems, there was nothing I could not fix. I dealt with integration problems as well as fixing java source code to achieve my goals.
I created CMRs, Project Management and Sales Support systems, connected to ERPs to fit into Customer’s processes. I have an experience with AWS stack including building EC2 CloudFormation with python and ansible using encryption and secrets to build reliable and safe integration solution for a big e-learning company. I have architected eCommerce omnichannel sales platform for such big brands as G-Star, Adidas, Tom Tailor, Golden Goose, Bestseller, connecting various eCommerce clouds with payment providers and mobile apps.
I like the teamwork also as two heads are better than one. Talking to people with an open mind creates synergy to break all walls and go further. And I love to encourage other people to do their best for projects. I'm used to working with business and technical people to get the requirements and build the solution. I worked from both sides as a customer and as a provider, so I know what is crucial to build a successful solution.
What I enjoy the most in my work is helping businesses to drive their functionalities by providing all technical aspects designed and implemented in the right way.
