WasilaDev signs with Nashwan Center, EGIC's agent in Yemen
Cairo and Sana'a, 27 October 2026. WasilaDev has signed an agreement with Nashwan Center for Building Materials (Nashwan Water Systems, NASH) in Sana'a, EGIC's agent in Yemen, to design and build the centre's website and a mobile app for plumbers and engineers. Work on both has started.
The agreement covers two projects in one scope: a fully Arabic website carrying the centre's catalog, and an Android and iOS app run from a browser-based dashboard. WasilaDev built EGIC's own site, and the referral came from there.
The new site follows the same structure as EGIC's, carrying Nashwan's identity, logo and colour. The reason is practical rather than cosmetic. A Yemeni plumber who reads an EGIC specification on the group's site meets the same logic and the same page order when he opens his local agent's site, so he does not learn two ways of reading the same specification.
What the app does, and what it does not
The first question anyone asks about an app for a building-materials trader is whether it sells. Here it does not. There is no purchase in the app, no order, no online payment, no cart. It is built around something else: the technical measurement, the مقايسة.
The reason lies in the market. In Yemen the person who recommends the product is the plumber or the engineer standing on site, not the shop. So instead of addressing the end customer directly, the centre gave the plumber a tool that makes his own work look better, and sent its catalog along with it.
A measurement that carries the plumber's name
- The plumber or engineer visits the site and opens a new measurement in the app.
- He records the customer's details, the location and his technical notes.
- He picks the pieces the job needs from the centre's catalog, by size and quantity.
- He exports the measurement as a PDF with its own number and date.
- He shares it with the customer from the phone's own share sheet.
The document is not a quotation from the centre. The plumber's name and details sit at the top, the centre's logo and a signature line at the bottom, and between them the table of pieces with sizes and quantities. Each measurement is kept under its own number, so he can revise it and reissue the file, and the dashboard shows which pieces recur most often across the market.
"The plumber in Yemen is the one actually choosing the part, and nobody builds tools for him. We gave him a document that goes out under his own name and makes his work look professional to his customer. In return the centre's name and sizes reach the end customer every single time. That is the real trade in this project."

Proof of work, and points for the plumber
The second flow documents a job once it is finished. The plumber photographs what he installed using the app's own camera, so the date and time are stamped on the image and nothing can be uploaded from the gallery. A reviewer accepts it or returns it with a note, accounts approve it, and the plumber's points are recorded. Points are points only, with no cash value and no redemption.
This tells the centre who actually installs its products in the market. A shop's sales ledger cannot answer that, because it records who bought the part, not who put it in the wall.
The website
The site is fully Arabic and right-to-left, on nashye.com, with a page for every product carrying its image, description, uses, sizes and specifications, browsing by brand, and downloadable PDF catalogs. It runs on a server inside the centre's own AWS account in Frankfurt, with daily backups. The whole setup is registered in the centre's name, not ours.
An agent building what the manufacturer builds
Agents usually make do with what the manufacturer gives them: a printed catalog, product photography, perhaps a page on the manufacturer's site. Nashwan Center built its own channel to the market instead, carrying all twelve of its brands together rather than one.
That is what makes the project relevant beyond Yemen. Any manufacturer selling through agents across several markets faces the same gap: it knows who bought wholesale, and does not know who finally installed the product or who recommended it. The tool that closes that gap gets built at the agent, close to the market, not at head office.
An unreliable network, and an app that works without it
Nashwan Center sells in a market where the internet connection drops. So the plumber browses the catalog, records the measurement, issues the file and shares it with the device offline, and everything syncs to the dashboard when the connection returns. That is an operating condition of the project rather than a later addition.
Where the work stands
The client has signed the requirements document, the interface design was approved on 25 October 2026, and the first development cycle began on 26 October. The app is built in Flutter to cover Android and iOS from one codebase, on a Node.js backend with a MongoDB database.
The centre holds written permission from EGIC to use its brand and content inside the site and the app, a condition written into the agreement.
About both parties
Nashwan Center for Building Materials (Nashwan Water Systems, NASH) in Sana'a trades in building materials, sanitary ware and water systems, distributes twelve brands, and is EGIC's agent in Yemen.
The agreement includes twelve months of technical support after delivery for both, and the app ships to Google Play and the App Store under the centre's own developer accounts.
WasilaDev is a software studio in Cairo that builds websites, systems and apps for companies across Egypt, the Gulf and Yemen, and stays with a project after delivery on a yearly support contract. Its clients include EGIC Group and Tahweel Group.
Companies selling through agents in more than one market all hit the same question: how do you reach the person who recommends your product on the ground, not only the person who buys it. If that is your question, the contact page is where to start.
