Aim of this project was to create online touchpoints for customers.
We have started with exploring customer needs, company goals and limitations. I prepared a series of workshops for technology understanding. Then created Architectural Drivers for future architecture and System Discovery Canvases (similar to X-Kom). I also helped with Customer Journey Map and roadmap.
During deeper analysis of first item from roadmap - eCare - my role was to prepare non-functional requirements, logical architecture and help with scoping and functional requirements. The result of this work was gathered in Service Blueprint.
Next, as a Team Leader I was responsible for technical setup before regular sprints start.
When agile delivery has started, I was supporting scrum team and at the same time defining eCommerce. Together with Business Architect we have conducted a series of workshops based on Story Storming. As a result we provided high level documentation for eCommerce with recommended software, domains with responsibilities and boundaries, architecture diagrams, high level requirements and business processes.
My role in this project was Solution Architect.

IT audit of X-Kom architecture divided into two parts: AS-IS and TO-BE.
In AS-IS started with existing documentation analysis, we read 100+ documents. Next, we have prepared anonymous questionnaire with more than 70 questions. We have got more than one hundred answers. Then we have series of workshops (20+). And during 30 days we talked about almost every X-Kom system. We also have additional workshops with business, configuration and infrastructure teams. The result of this phase was current architecture in C4 model and a report with rating for each system in 4 areas: elasticity, scalability, reliability. We have also created System Model Canvas (based on Business Model Canvas) for each system and ratings heatmap.
During To-BE we focused on creating a future vision on architecture landscape. Based on workshops with business, it and security we have prepared:
- technical debt report,
- future architecture vision in C4 model,
- recommendations with roadmap.

Work Experience
Just started ;-)
After some time of being an expert, I decided to go back to my root and work as a team member. Other thing that I wanted to change was to move from “big products” to something smaller and open source. That when I have meet and learned microservices and cloud.
80% of my time I have spent on projects for Deutsche Telekom, Fortum, UPC, X-Kom and lately Osadkowski.
Rest of my time I have dedicated for knowledge sharing and learning.
I have been very active on company level. I have become leader of Cloud circle. My biggest achievements were creating course for employees about microservices and cloud. Convincing, organizing budget and helping with cloud certification on AWS and GCP. I initiated architects meetings. Make some presentations about microservices and projects that I was involved in. I have also been one of the person that created Hycom’s Unified Delivery Methodology. That was a guideline with standards about project realization from design to delivery.
I have been involved in few projects with Technical University of Lodz. First one “Implementacje Przemysłowe” was a regular subject from university (Faculty of Technical Physics, Information Technology and Applied Mathematics) in cooperation with Hycom. I have been part of it a couple of times. Together with students we were making small projects like Facebook chatbot or Confluence plugin. Other initiative where together with students council (Faculty of Electrical, Electronic, Computer and Control Engineering) we have prepared an on site programming course. The topic of the course was: “Hy!Class: Tworzenie mikroserwisów z wykorzystaniem Spring Cloud oraz Netflix OSS”.
Together with my colleague had a presentation on “Akademickie Targi Pracy”. We have talked about TDD and the topic of our presentation was: “Developer nie SAPER, myli się nie raz”.
Next there was workshop for “Młodzi w Łodzi” with topic “Hy!Class: Zwinne wytwarzanie oprogramowania”. It was an interactive workshop where I was teaching students about agile and scrum. During the workshop we have played a lot of games like Agile Values Puzzle Game, Marshmallow challenge, Airplanes production.
My last public presentation was on JUG (Java User Group) in Toruń where together with my colleague we were talking about it architect role. Topic of presentation was “Hy!Class: Co robi architekt?”.
Last but not least, I have also been a guardian for a few people. I was responsible for their personal development and career path.
The next change in my career was to move from development to consultant/expert role.
At the first 6 months I was working full time in Germany/Bonn at Deutsche Telekom headquarter. Later I was working partially in Germany/Bonn, partially in Poland/Łódź.
I was working with people from all over the world. Mostly I was involved in creating design guidelines for T-Mobile online stores in Europe based on Oracle ATG. I was also participating in meetings and presentations, researching and documenting application integrations, comparing products and technologies: ATG vs Hybris, Portlets vs. Servlets, etc. In general, I was Oracle ATG and integration expert cooperating with many Deutsche Telekom teams and departments.
During this time I was working with Oracle ATG, Sitebuilder from Spindrift, Oracle Knowledge, CoreMedia, Siebel products.
I was involved in projects:
- eCompany - ATG - Siebel integration POC
- eGarage - digital transformation project
- T-mobile PL (t-mobile.pl) - polish telco store
- T-mobile NatCo’s in Europe - national companies initiatives
AMG.net, Bull, Atos
Trainee - IT Architect
April 2008 - August 2013
I started my real IT developer journey as a trainee in AMG.net. I was one of the best students and during the first phase of training I understand what this coding is all about. The second phase of training was work on a real project, in my case it was Orange portal.
After training, I’ve stayed in AMG.net. Very fast, I was assigned to “Functional Expansions” as projects technical team leader. Team was small from 2 to 5 people. It was rather small, recurring projects with changes too small to put them in big release. Usually, development took less than a couple of days. Together with my colleague, we have manage to make this project as a role model for others. We manage to make it profitable, good documented and well communicated.
During that time I was responsible for almost whole delivery process. From design, develop to delivery preparation. My role was to prepare pricing for the change, document, implement, test, merge it and prepare deployment instructions. I was also responsible for maintaining development environment.
After a few years I’ve decided to move to something bigger.
I’ve stayed in Orange, but moved to big releases. I was involved in eCommerce part. Most of my responsibilities were the same but on a much bigger scale. During that years I was also responsible for code refactoring, performance optimization, source code quality, third-party audits analysis, big commerce architecture modifications. From time to time I’ve also helped in other regions of Orange, e.g: nju mobile eShop.
Apart from Orange, I was also very active on company level. I was participating in offering processes, employee and students trainings. I was also involved in internal projects. I have crated and administrated plugins for Confluence and Crucible from Atlassian stack.
