Federico Stella - Illuminem

Great guy to work with. He possesses outstanding design, content creation and technical skills, while also having very useful perks, like a strong project management attitude, and providing advice and insights on how to make the product better. I worked with him on a very big project, so the perks I mentioned were particularly useful and important.

Niels Van Beek - Product & Service Designer

Seif is undoubtedly an incredibly driven, knowledgeable and skilled developer, project and product leader. I would trust him with any topic or team. I worked as a UX/UI designer together with Seif on a web product for the energy sector for three months. His honest cross-functional leadership and ability to manage and connect with the client, in addition to managing the entire product development and launch process easily qualifies him to be the best guy for almost every challenge. He might not always say what’s most convenient however ultimately this will help to get the best results. Seif navigates and translates between the worlds of business, tech and user experience - and lives the wise humbleness to seek advice of others in their fields of expertise.

Tinloof is capable of building amazing products. Seif, Omar, and their collaborators were entitled to build from zero a complex website, from the back-end architecture, to the CMS and the front-end. The project lasted 4 months, and Tinloof has demonstrated compelling IT hard-knowledge (JavaScript, CSS, Python, etc.) to construct anything required and the ability to outclass in project management, communication and front-end skills. The project consisted of developing a hub of information, aggregating multiple sources automatically, and displaying selected posts across different sections in the platform. Given the high level of automation, together with the customization via CMS, the job involved a complex architecture and many challenges. Tinloof excelled in critically resolving any problem faced while assuring quality and effective solutions. Accordingly, within the project's scope, almost everything was possible thanks to the breadth and depth of their IT skills. Tinloof surprised in project management skills. Upon contract signature, they promised to be the partner to trust to manage different people involved (from other developers to designers). Not only they did so, but further brought efficiency to the project development by being the "light-house" of the wider IT team. Thus, never lagging-behind, they pushed the project management to the next level. As regards to communication, by using Trello, video calls, and instant messaging, they were transparent in showing their pipeline of work and demonstrated instant availability (a call away at any time!) to respond to every request. Despite the best-practises, we faced once a misalignment on a decision. To avoid this in the future, Tinloof acted proactively by proposing to send memos after the meetings to track decisions and ensure that both parties were aligned. A particular note is for their front-end skills. We echo what their website says: "Front-end experts". The platform performs at cutting-edge levels in performance (1.3 seconds to load the heaviest page), SEO (lighthouse score of 98%), accessibility and responsiveness (mobile is particularly excellent). After product validation, our users were amazed by the UI/UX design, something looking "professional, even better than dominant incumbents in the market". Thus, we maintain that Tinloof's problem solving, reliability, project management, communication and front-end skills set them apart. After 4 months of journey, they proved to be capable of building amazing products.

I worked closely with Seif during these past months crafting a product from Scratch. Seif demonstrated strong expertise in front-end development especially with JS stacks technologies (React, NextJS). He always aims to deliver scalable, performant solutions. I also want to highlight his skills in project management within a team with different roles and backgrounds which he led successfully. He has eased to grasp technical as well as functional subjects in projects.

Omar Benseddik - Tinloof

Seif is an experienced and strong software developer that led the project Illuminem (energy news aggregator) from 0 to 100. We worked closely on each feature and he managed the project with great attention to detail and a very organized workflow using tools like Trello and Notion. Seif is an expert at JavaScript, React and CSS. He also masters the framework NextJS and managed to boost the Lighthouse performance of the project to 100. He built complex features, integrated the project with Sanity CMS and supported both the backend developer and designer. Working with Seif is a pleasure. He is direct, knowledgeable, available and very effective in his approach.
