Working with a team of Googler on a Google Artificial Intelligence Impact Challenge award winning app that would help doctors and clinicians diagnose antibiotic resistance in low-resource settings. The Antimicrobial Resistance is a major public health concern. By 2050, Antimicrobial Resistance could become the first cause of death all over the world. Access to a good diagnosis of bacterial diseases is usually not available in low-resource settings. This leads to non-appropriate patient treatment and to the selection of resistant strains because of the non-rational use of broad-spectrum antibiotics.
Coached & helped a team of googler on react-native development best practices.
Developed an AI expert-system based on one of the industry leader knowledge bases (i2A).
Trained a machine learning model to recognize antibiotic pellets with Keras and TensorFlow.
Detect antibiogram diameters using image regnition algorithm with OpenCV.

Antimicrobial resistance is a major global health threat and its development is promoted by antibiotic misuse. While disk diffusion antibiotic susceptibility testing (AST, also called antibiogram) is broadly used to test for antibiotic resistance in bacterial infections, it faces strong criticism because of inter-operator variability and the complexity of interpretative reading. Automatic reading systems address these issues, but are not always adapted or available to resource-limited settings.
We present an artificial intelligence (AI)-based, offline smartphone application for antibiogram analysis. The application captures images with the phone's camera, and the user is guided throughout the analysis on the same device by a user-friendly graphical interface.
An embedded expert system validates the coherence of the antibiogram data and provides interpreted results. The fully automatic measurement procedure of our application's reading system achieves an overall agreement of 90% on susceptibility categorization against a hospital-standard automatic system and 98% against manual measurement (gold standard), with reduced inter-operator variability.
The application's performance showed that the automatic reading of antibiotic resistance testing is entirely feasible on a smartphone. Moreover our application is suited for resource-limited settings, and therefore has the potential to significantly increase patients' access to AST worldwide.

“ Amine was involved in a complete mission: setting up a technical stack from scratch, creating and leading a team of high-qualified talents, implementing working methods and delivering the asset. This mission took place in a complex context in terms of business requirements (banking), technical needs and governance (internal and external stakeholders). Amine has in-depth expertise in software and mobile development. He is highly professional and passionate bringing innovation and best software engineering practics. Also, Amine has shown an excellent ability to take into account the business challenges and constraints of the company in order to guide technical choices, and deliver on schedule. An excellent leader, Amine is keen to get his teams to rise to the top in a demanding and benevolent way. He can also report & discuss with top management thanks to a good grasp of the issues at stake and an ability to summarise them. I'd recommend him without hesitation and would be delighted to work with him and Xsquad again. ”
“ Amine a été mon lead dev puis mon CTO sur la mission Oney, il a non seulement un niveau technique exceptionnel mais en plus de ça il sait comment faire monter en compétences tous les membres de l'équipe. En presque 10 ans de carrière ma rencontre avec Amine est celle qui m'a permis de monter le plus en compétence ! Il a fait l'unanimité de toute l'équipe technique et nous a guidé pour construire une application de haute qualité avec les principes de la Clean Architecture. Je le recommande les yeux fermés en tant que CTO, il saura mener à bien votre projet quelque soit sa complexité ! Merci Amine encore une fois pour tout ce que tu as pu m'apporter 😀 ”
“ Amine est plus qu'un CTO ou tech lead. C'est un véritable mentor avec un niveau technique impressionnant. Ma façon de concevoir des programmes a completement mûri et grandi grâce à ses profondes connaissances en Clean Architecture et Techniques de programmation. Toute la partie back-end de Oney a pu être remodelisé et remasterisé de façon à avoir des couvertures de tests optimales, un code qui raisonne dans l'esprit des Product Owner et non tech, et un vrai confort de travail pour toute l'équipe de developpement dans un projet aussi complexe qu'est une banque digitale. C'est une vraie pièce maitresse pour tout projet, et un vrai facteur différenciant avec une grande expérience pour mettre au centre de la production tous les acteurs d'un projet, du développeur junior jusqu'au CEO. De plus, il possède des capacités de managements hors pair qui allie une très grande maitrise technique et capacité à pousser les membres de l'équipe technique au delà de leur champs de connaissances. Encore un grand merci pour tout 😀 ”
“ Dans un contexte à forte pression lié à une deadline très forte et une double casquette (Lead équipe dev mobile + Production technique), Amine a été un renfort de poids et une ressource indispensable pour le bon déroulé du projet. Expert sur la partie technique et très apprécié de l'équipe, il a su mettre en place, avec son équipe de 3 développeurs, une architecture projet solide et pérenne. Pour vos besoins techniques, ou d'encadrement technique, je ne peux que vivement recommander Amine ! ”
“ Amine a un très bon niveau. Il était lead mobile sur notre projet, il nous a permis d'architecturer le projet de façon robuste. Il m'a fait découvrir la clean architecture et d'autres façon de travailler afin d'avoir un produit plus facile à maintenir et développer. Ce fut une plaisir de travailler avec lui, et je n'hésiterais pas à travailler avec lui à l'avenir sur d'autres projets si l'occasion se présente. ”
“ Amine has been fantastic to work with. We collaborated in a small group working with MSF to develop an application to facilitate antibiotic susceptibility testing in low resource settings, and his dedication and expertise helped us make rapid progress to get an MVP out for testing. What's more, Amine is the type of person who curates a kind and fun environment for everyone around him which I really appreciate. ”
“ Amine's expertise in the React-Native ecosystem has been invaluable for our project. When 3 engineers from Google joined the MSF project, Amine was our go-to person as we had to ramp up on React-Native, Redux, TypeScript, etc. His guidance, reviews and attention to detail accelerated our on-boarding process a lot. I also admire his passion for quality, clean code, and best Software Engineering practices, which helped us set up a sustainable project through test automation, continuous integration, and continuous delivery. I would love the opportunity to work with Amine again, and would be happy to recommend him as a Software Engineer to my friends and colleagues. ”
“ Notre projet d'application mobile était en difficulté entre les mains d'une agence à l'étranger. Amine est intervenu en tant que lead technique, il a remis le projet sur les rails, il nous a aidé à faire les bon choix d'architecture et à assuré le suivi du projet sur plus d'un an. Il a mis en place pour nous les outils nous permettant d'atteindre un bien meilleur niveau de qualité. Il a également lui-même développé les parties métier les plus critiques sur Android et iOS avec une bibliothèque commune en Kotlin. Son excellent niveau technique en plus de ses compétences de lead nous ont permis de déployer notre application dans les délais. Il intervient encore pour nous occasionnellement pour supporter l'ingénieur que nous avons depuis recruté sur ce projet. Une très belle réussite au final, je recommande Amine à 100% ! ”
