--- title: "I am the technical department for Raumluft24 — isla Studio" url: "https://isla-stud.io/projekte/raumluft24-woocommerce-shop-weiterentwicklung/" date: 2026-09-10 --- # I am the technical department for Raumluft24 At the end of 2020, I received a call from the managing director of [Raumluft24 Klimatechnik GmbH](https://raumluft24.de/). „Are you at your computer right now? Then just take a look at our web shop… I don’t think I need to say much more, do I?“ We were quickly in the middle of a detailed consultation. Even then, the first rough concept for the new shop took shape. I brought in the right design partner for the project. After the proposal was accepted, we moved directly into the concept and design phase; the new website went live in February 2021. Since then, I’ve been overseeing its further development and managing the technical aspects during day-to-day operations. Raumluft24 sells a relatively manageable range of air conditioning units. Over the years, a complex shop system has developed behind the scenes. On the client side, there’s a sales team without its own IT department. I take on that role: I handle server operations and shop maintenance, develop custom features, and advise on how to technically implement new requirements. What Goes Into the Shop --------------------------------- Since the relaunch, we’ve expanded the website step by step. We’ve added special landing pages—specifically designed entry pages—and a blog. An interactive air conditioner advisor and additional information on energy efficiency have been integrated into the store. We’ve also implemented an internal, secure store for dealers and spare parts. As a result, the same website now serves very different purposes. Anyone looking for information about an air conditioner uses the public store. Dealers and other commercial customers can receive detailed advice by phone and place their orders. The friendly team is happy to help and accesses the secure store area to do so. The air conditioning advisor must integrate seamlessly into the system, just like the ordering functions. Additional processes are connected via interfaces, such as those related to payment, invoicing, and shipping. When I develop a custom feature, I need to understand these connections. A change can affect areas that aren’t even visible on the page in question. That’s why part of my job is to translate the sales team’s requirements into a technical solution and assess its impact on the existing online store. Server operations and online store development go hand in hand here ------------------------------------------------------- This can be explained well using caching as an example. To prevent the online store from having to rebuild all content from scratch every time it’s accessed, we use multiple caches. The server can store pre-rendered public pages; another cache level holds frequently accessed data. I set up the server myself and configured it entirely to meet the online store’s requirements. I oversee day-to-day operations and coordinate the server infrastructure with the store’s functions. The quality of this setup is particularly evident under high load—such as during major advertising campaigns, computationally intensive tasks, or waves of bot attacks. That’s when it matters that the server and website function as a well-thought-out, coordinated system. Different rules apply to the shopping cart, checkout, and logged-in customers than to a public product page. Here, the store must take into account the specific purchase and the user’s personal session. These areas and individual states are therefore specifically excluded from the page cache. The technical challenge lies in reusing content effectively while also accounting for the processes that vary with each purchase. Even a page that loads quickly says little about how efficiently the entire ordering process runs. Interfaces and additional background requests also play a role. When providing support, I therefore examine how the server, the online store, and these requests work together. Focusing solely on the visible page would overlook a significant portion of the work. [Review existing online stores, interfaces, and operations in the e-commerce system.](https://isla-stud.io/beratung/e-commerce-system-review/) Continuously developing the online store during live operation ---------------------------------------------- A recent example is the new product pages, which have been online since September 2026. I implemented the technical design and integrated it with the existing store functions. Key features are displayed directly in the checkout area, while more detailed information can be expanded. In the product comparison, visitors can view factors such as room size, noise level, and energy efficiency class side by side. I prepare major overhauls and software updates in a separate test environment. There, I test the changes alongside the existing features before they are deployed to the public store. For me, this is part of my responsibility for a system in which orders continue to be processed even as development proceeds. Consulting also involves bringing in the right specialists. About a year and a half ago, I brought in one of my SEA partners and introduced him to the client. He specializes in search engine advertising; since then, the ad campaigns have been continuously optimized through this collaboration. Just as I did with the design partner at the beginning, I brought the right technical expertise into the project. If the Raumluft24 team needs a new feature, they can come to me with their technical request. It’s my job to determine which technical components need to be modified and how they’ll integrate with the existing store. It helps that I’ve been involved with the project since the initial concept phase and also oversee its day-to-day operations.
