Web Design & UX/UI
Case Study #1: CoolAir Systems
Problem Statement
The client, CoolAir Systems, was a company in the HVAC industry and needed a new website to showcase their products and services. The main challenge was to create a website that would appeal to a specific target audience, which included clients from the construction and shipbuilding industries. CoolAir Systems had a well-established brand, but the challenge was to develop a creative line that would help the company reach new, larger clients in the aforementioned industries.
Research
To address the problem, we conducted persona research and A/B testing to better understand the target audience and their needs. Through these research methods, we were able to gather information about the target audience’s preferences and behaviors, which helped inform the design process. Additionally, we reviewed existing materials, such as the company’s existing logo, to determine the design direction that would align with the client’s goals.

Design Process
The design process was informed by the research and was guided by two main goals: to create a unique and cohesive brand identity, and to clearly communicate the company’s content and services. We worked closely with the client to develop a design solution that met their needs and reflected the findings from the research phase.
Design Solution
We designed a new website for CoolAir Systems that was visually appealing and easy to navigate. To make the content easy to understand and accessible, we compressed the content and divided it into sections, each focusing on a specific area of the company’s services. We also designed a set of symbols that represented each area of the company’s operations, using gradient and multiplied lines to convey key themes such as flow, movement, and the company’s HVAC focus.

Evaluation
The design solution was evaluated through user testing and feedback from the client. The results indicated that the website was well-received and met the target audience’s needs. The website was well-organized, easy to navigate, and visually appealing, making it a success in achieving the goals set out in the design process.
Reflections
The biggest challenge of this project was the lack of quality images and limited text available. To overcome this challenge, We had to be creative and make the best use of the available resources. The end result was a well-designed website that effectively communicated the company’s offerings and services. This project taught us the importance of being flexible and resourceful in the design process.


Conclusion
In conclusion, the new website for CoolAir Systems was a success, effectively showcasing the company’s products and services to its target audience. The research and design process was informed by the target audience’s needs, resulting in a well-received and effective solution. This project demonstrated our ability to conduct persona research, perform A/B testing, and design a website that meets the needs of a specific target audience. The website was well-organized, visually appealing, and easy to navigate, making it a success in achieving the goals set out in the design process.

Case Study #2: Science Tree
Problem Statement
The problem that the Science Tree platform aimed to solve was to provide students with a comprehensive, yet user-friendly platform that would help them learn science in a more efficient and engaging way. The client, a full-time tutoring teacher, wanted to create a platform that would allow him to reach a larger number of students and provide them with a more personalized experience.
Research
To understand the needs of students, we conducted user research using a combination of methods, including:
- Surveys: we created an online survey to gather information about students’ needs, preferences and pain points when it comes to learning science.
- User Interviews: we conducted in-person interviews with a group of students to gather deeper insights into their needs and preferences.
- Competitor Analysis: we analyzed existing tutoring platforms to understand the strengths and weaknesses of the competition and identify opportunities for differentiation.

Design Process
Based on the insights gathered from the research, we followed the following design process:
- Ideation: we developed a range of design concepts that addressed the key needs and pain points of students.
- Prototyping: we created high-fidelity wireframes and interactive prototypes of the most promising design concepts.
- User Testing: we tested the prototypes with a group of students to gather feedback on the usability, functionality and overall experience.
- Iteration: Based on the feedback from user testing, we made iterative improvements to the design.
Design Solution
The final design solution was a website that looked like a dashboard, making it easy for students to navigate and use. The platform was divided into specific departments, each with its own set of resources and materials. The platform also included a tutoring booking system, allowing students to schedule online tutoring sessions with the teacher. Additionally, there was a commenting system that allowed students to communicate with the teacher and each other, providing a more interactive and engaging learning experience.

Evaluation
To evaluate the success of the Science Tree platform, we collected data on a number of metrics, including:
- User satisfaction: we surveyed students to gauge their overall satisfaction with the platform.
- Engagement: we tracked the number of students who used the platform and the amount of time they spent on it.
- Conversion rate: we tracked the number of students who signed up for tutoring sessions through the platform.
The results were very positive, with high levels of user satisfaction, engagement, and conversion.

Case Study #3: GDE
Problem Statement
Gdańskie Dni Elektryki (GDE) is a project for the Association of Polish Electricians (SEP), a community of technical electrical and energy professionals. The event was a big challenge in terms of rebranding due to its long-standing tradition. The client was fairly conservative and the GDE audience was divided into four groups: Sponsors, Companies as exhibitors, Participants as employees of companies and electrical enthusiasts, and Students looking for work. Such a diverse audience required the need to conduct UX analysis and research to create a universal website that would attract both large companies as sponsors, a large number of companies as exhibitors, and hundreds of participants and visitors. Part of the event registration was paid (for exhibitors), and part was free (for participants), so it was important to guide the user through the website appropriately (User Flow). The whole was based on a consistent visual identity, creating a sort of Design System for future years of organizing Gdańskie Dni Elektryki.
Research
In order to understand the needs and expectations of the GDE audience, various research techniques were used. This included creating personas, conducting A/B tests, and conducting interviews with representatives from each target audience group. The research helped to identify the main challenges and opportunities for the website design.

Design Process
Based on the research findings, a design process was established to create a website that would meet the needs of the diverse GDE audience. The process involved creating wireframes, prototypes, and user flows to ensure a seamless user experience. The design also incorporated the established visual identity to maintain a consistent brand image.
Design Solution
The final design solution for the GDE website was a user-friendly and visually appealing platform that effectively communicated the purpose of the event and encouraged participation. The website was divided into several sections, each clearly explaining a different part of the event, such as the Scientific Conference, Company Fair, Industry Meeting, and Technical Seminar. The user flow was designed to guide the user smoothly through the registration process, whether it was a paid or free registration. The website also incorporated features such as a schedule of events and a list of exhibitors to enhance the user experience.

Evaluation
The effectiveness of the GDE website was evaluated by conducting user testing and collecting feedback from representatives of the target audience. The results showed that the website was well received and effectively met the needs of the diverse GDE audience. The user flow was smooth and easy to navigate, and the information was clear and concise.
Reflections
The design of the GDE website was a successful example of how research and a user-centered design approach can lead to a successful outcome. The process of creating personas, conducting A/B tests, and conducting interviews helped to ensure that the final design solution met the needs of the target audience. The incorporation of a consistent visual identity also contributed to the overall success of the project.

Conclusion
In conclusion, the redesign of the Gdańskie Dni Elektryki website was a challenging project given the diverse target audience and the need to maintain the event’s long-standing tradition. However, by conducting thorough user research, creating personas, and utilizing a consistent visual identity, we were able to develop a user-friendly website that effectively addresses the needs of all its users. The new website received positive feedback from both sponsors, exhibitors, attendees, and students seeking job opportunities, and was instrumental in attracting a larger number of participants to the event. The success of this project serves as a testament to the importance of UX/UI design in creating effective digital solutions. The design system developed for this project will also serve as a foundation for future editions of the Gdańskie Dni Elektryki.
