I Craft The
Digital Landscape
I am a seasoned software engineer with over a decade of experience in the tech industry.
I have collaborated with numerous enterprises:
from startups to corporations, from Europe to the USA.
My services have reduced costs, increased profits,
and supported the digital transformation of many areas of life.
I worked with:
For first five years of my career, I have worked as a full-stack developer. My backend tech stack was .NET and C#.
I am skilled in designing RESTful APIs and mastered principles of Object-Oriented-Programming. I understand TDD. I worked with SQL and NoSQL databases (MongoDB & Redis).
I have many years of experience working with the React framework. Since early 2021, I have also worked with Next.js, mainly using both with TypeScript.
Across multiple projects, I have utilized technologies such as: Redux, Storybook, Tailwind, Material UI, Chakra UI, Styled Components, TanStack Query, GraphQL and Apollo Client, Jest, and React Testing Library.
I have hands on experience with configuring infrastructure for mid-size projects. I used Docker, Kubernetes and Jenkins to configure automated deployments and CI/CD pipelines.
Fascinated by prospects of LLMs and Stable Diffusion I spend my free time to learn ML and AI to pursue my teenage dreems of making sci-fi worlds become reality.
For the American startup, Justpoint, I developed various small sized and fast paced projects.
The biggest of them was successful migration of custom CMS from jQuery to Next.js which eliminated code debt and allowed maintenance.
On top of that I delivered multiple new features to CRM system. It boosted the performance of the company in terms of new clients processing and allowed it to grow sales. Another of the projects was quick implementation and deployment of e-mail signature generator which positively impacted e-mailing and improved spam rating.
Last but not least I performed rapid and flawless changes of Justpoint.com homepage (see above).
Wikifolio.com is an investment and copy trading platform developed by an Austrian startup. It enables users to follow the transactions of successful traders and also offers investment certificates based on the best portfolios.
I participated in rebranding the search and portfolio details pages, which involved implementing a new design, enhancing the user experience, and updating the technology. I contributed to accelerating the performance and implementation of user tracking features. Alongside the client's team, we engaged in product development scrum meetings and code reviews.
For Austrian fintech startup Credi2, I have worked on development of their BNPM (buy-now-pay-later) platform for renting Apple devices.
I contributed to development of many new features such as cross-sell recommendations, subscription early upgrade, electronic identification of users as well as creation of new separate module of the application.
I worked on technical aspects of the platform including refactoring of legacy code, implementation of analytics and improving translation mechanism. On top of that I participated in product development scrum meetings and was performing code reviews.
I was part of the engineering team of mBank - one of the largest banks in CEE region. I developed an advanced online banking platform that allows clients to securely manage their financial assets, monitor account balances, transaction history, and execute both internal and external transfers.
In particular I worked on PSD2 implementation (European regulation that mandates banks to provide third-party providers access to their customers' account data, given the customers' consent), and - more importantly - main bank transfer form (see above).
I would like to highly recommend Arek based on our work at Justpoint. Arek has very systematic approach to building software. He focuses not only on task at hand but also on overall problem software needs to solve and how those problems can be solved without sacrificing codebase quality.
Arek possesses a remarkable attention to detail and quality. He has consistently demonstrated a keen eye for spotting issues with the code but also with overall user experience. His commitment to testing produced code thoroughly reflects his dedication to delivering high-quality work.
Apart all of that we spent countless hours on discussing engineering topics where Arek shines especially when we talk about architecture or development patterns.
I have had the pleasure to work with Arkadiusz in two projects. And a pleasure it has been. Arkadiusz has proven to be a highly skilled and experienced developer. Arkadiusz is not afraid to ask questions, seek out new knowledge and take ownership. Good communicative, analytical and personal skills are among the central traits which makes Arkadiusz such a good team mate. I would like to give my warmest recommendation to Arkadiusz.
Arkadiusz is a gifted developer with a rare combination of qualities like patience, ability to look at the problem from different perspectives, detail orientation, and research skills. I'm lucky to have worked with Arkadiusz, he is responsible and goal-focused. He definitely will help you to deliver the desired solution on time.
It has been now over a year and a half since Arkadiusz joined the Front end team at Credi2. I'd say his scrutinous attention to detail, pragmatic approach when dealing with complex situations; both technical and concerning internal work flow processes, his will to elevate the code base of the product and his broad tech stack are some of his most valuable qualities.
I can also say he has played an important role in my professional development as he has always been patient and ready to lend a helping hand as Senior Developer whenever I needed guidance, help or simply a nudge in the right direction. I can recommend Arkadiusz as a diligent Senior software engineer.
I have worked with Arkadiusz at Fujitsu. I've seen his growth and transformation from talented, hardworking software developer to seasoned senior software engineer. (...)
Technology stack of it was: React with Redux, Material UI, Node.js, Express.js, and MongoDB. Arkadiusz participated in the project with full proficiency and adapted to new technologies seamlessly despite the lack of experience in most of them.
Arkadiusz is outstanding and fully dedicated professional. He is a very energetic, well organized, creative and productive employee. He has always behaved in the utmost professional manner. It has been a privilege to work with him and I strongly recommend Arkadiusz for any position related to software development.
I have had great opportunity to work in the same team with Arek and see closely his skills and ability to execute. Arek has all the characteristics of an excellent software architect. He is very solution-oriented. In case of problems, he does not stop, instead he seeks for solutions even when the problem lies outside his responsibility area.
Arek can adopt new technologies quickly and directly utilize these in his work. He is a great team player and brings new ideas on the table. Most important, he is very productive and produces easy-to-use, appealing software applications on-time.
