About the Project

Celsia gives you the simplest way to your EU Taxonomy score.

The EU taxonomy is a complex system to classify which parts of the economy can be marketed as sustainable investments. It includes a long list of economic activities, plus detailed environmental criteria that each must meet to earn a green label.

The platform provides the opportunity to measure, manage and improve sustainability activities in 4 steps using EU Taxonomy software.

Challenges & Solutions



Create a re-design for the website.
We worked on building a new UX structure and sitemap to assure the presentation of Celsia services was executed in the most efficient way possible. With the references and style guidelines we’ve gathered, our designer was able to create a new fresh look to represent the brand with captivating UI design, incorporating custom illustrations.
Implement everything via the Webflow platform.
We implemented the new website on Webflow, as requested, incorporating low code and no code solutions into the project. We also worked on custom integrations of several APIs, adding a separate secure storage option for collecting user data, and providing an opportunity for efficient SEO and marketing solutions.
Create a CMS for blog and product pages.
WarmDevs provided the Celsia team with custom CMS solutions. This allows the client to customize their blog and product pages further, once they need to incorporate any updates, negating the necessity to predict potential needs rising in the future. Instead, this solution provides the client with the tools to make their team self-sufficient after the initial product is completed by the development providers. Instead of relying on developers for after-delivery long-term support, the client will be able to make changes themselves as they see fit, ensuring them more freedom and flexibility.
Integrate login and subscription options into the website.
The client needed their customers to be able to login and subscribe to services on their website since their model is a SaaS platform. WarmDevs experts created custom forms for these features and made these operational on the new website.

In every project, we divide workstreams and determine milestones. Then we identify competencies needed to fulfill the tasks, calculate the work time of each expert, and approve everything with the client. After signing the contract, we allocate a separate team for the project. The project manager directs and supervises the process; he is the contact point for the client.

We started our collaboration with a kick-off meeting to gather information on the project. Our team discussed the project scope with the client, figured out what they expected from the product delivery, and defined, what tasks lie before use.

Using the Scrum method, we divided our work process into Sprints. Each Sprint is designed to produce a certain value – a deliverable we’ve presented to the client by the end of each Sprint’s period.

According to the project plan, we assigned a suitable team to work on it: a project manager, a designer, a developer, and a QA tester.

UX/UI design

Before starting to work on the front design, we’ve built a sitemap: created the wireframe, and structured an overall UX logic of the website.

After that step was done, our designer assembled UI style guidelines to work within. This included brand colors, typography styles, iconography, and grid system. The designer detailed suitable spacing, text fields, buttons, and cards as well.

With collected references and the groundwork set and done, the designer created the UI design you can today see on Celsia’s live website.

Web development

Webflow implementation is a complex and involved process, that can be roughly divided into several main parts.

For this project, our developers implemented 12 main pages for the site, such as the Home page, Blog page, FAQ, Contact page, Privacy Policy, Product page, Pricing page, login, and subscriptions form, among others. We also created 2 custom Webflow CMS templates for product and blog pages.

After our developers and QA testers finished their part, the website was ready to go live. We proceeded with the successful deployment of the product.

3rd party API integration

WarmDevs incorporated a login form for users to create their own account. We added a subscription form on the website, which users can use to sign up for and stay updated on the company’s services. Also we’ve added Hubspot cloud software as a CRM platform incredibly useful to marketers for automizing inbound marketing, sales, and overall customer service, and provided Zapier product for the website to allow users integrate web app they use to automate their online operations. Our devs used JavaScript to implement additional interactivity to the website.
