Sami Dahoux

- Founded Qitab, a startup building a next-generation platform for systems engineering that combines requirements management, system modeling, and traceability in a unified solution. - Incorporated formal methodologies from systems design and digital transformation, positioning Qitab as more than a documentation tool — a bridge between engineering best practices and modern software workflows. - Led all aspects of product development, from software architecture and implementation (Rust, web technologies) to roadmap definition, product vision, and early customer validation. - Actively engaged with the engineering community to shape product direction and align with industry needs in aerospace, automotive, and high-tech systems.

- Pursued continuous self-learning through online lectures from MIT, Stanford, and Harvard, covering topics such as cryptography, algorithms & data structures, computer graphics, and image processing. - Explored advanced scientific concepts by combining academic papers with hands-on prototyping in areas like differential geometry and physics simulation. - Designed and implemented an AI face detection pipeline using the Viola–Jones method, from feature extraction to classifier training. - Built a custom physics engine to simulate dynamics and collisions, later integrated into open-source games and visual demos. - Developed a custom made CMS to manage my portfolio content dynamically and generate static website as well as PDF resume - Published several open-source libraries and simulations on GitHub, some distributed via npm with 5,000+ downloads. - Applied agile development and continuous integration practices across personal projects to ensure quality, maintainability, and real-world applicability.

- Joined the company as the 2nd engineer in a 4-person team, contributing to the development of a Product Lifecycle Management SaaS for managing industrial product data (documents, 3D models, production batches). - Designed and implemented new features across the stack (databases, APIs, back-end services, front-end components), from draft specifications to deployment and maintenance. - Acted as a technical reference, providing advice on key features, leading code reviews, and advocating for best practices in software engineering and project management. - Conducted technical onboarding for new customers, serving as the interface with Customer Success. Designed and managed onboarding automation tools, reducing onboarding time by ~25% (1 week saved on a 1-month cycle) and enabling safe deployment of hundreds of Go. - Extended this automation into a back-office product, later integrated into the main application, giving customers a simplified onboarding process. - Trained and mentored new employees and junior developers, mobilizing resources on major projects while ensuring knowledge transfer. - As the startup scaled to 20 employees and raised funds, the role evolved from full-stack engineer to project manager with senior technical responsibilities, contributing to both product growth and strategic technical decisions.

- Contributed to the development of Urbalis Fluence, Alstom’s next-generation Communication-Based Train Control (CBTC) system, deployed on Shenzhen Metro Line 20 (China) in a high-density urban context. - Supported the functional architecture and design specification of the automatic train control system, collaborating closely with system architects. - Defined and refined requirements with traceability to ensure alignment with safety, performance, and operational needs. - Produced preliminary software design documentation and ensured compliance with verification and validation processes. - Analyzed change requests and contributed to troubleshooting activities to address system integration issues. - Presented new system features to the software development team, clarifying expected behaviors of trains and network devices, and facilitating discussion on potential implementation challenges.

- Designed and developed SCABox, an open-source demo bench for evaluating the resilience of cryptographic algorithms against side-channel attacks (SCA), a class of hardware attacks exploiting power consumption traces. The project is available on GitHub. - Collaborated with an academic research team to study SCA fundamentals and extend their proof-of-concept code, which later supported the publication of a research paper. - Acted as principal engineer, leading the design and implementation of the entire solution from scratch: - FPGA test bench on a Zybo device with integrated power sensors. - C driver application to control the bench and execute attacks. - Python client application for remote control, data acquisition, and cryptanalysis (key retrieval). - Demonstrated the recovery of AES encryption keys from the widely used OpenSSL implementation. - Enabled deployment of the bench on remote servers (e.g., Amazon EC2), with client-server communication for attack automation. - Awarded Best Demo at the IEEE HOST Symposium 2022.

- Managed merchant onboarding for a French payment solution similar to Amazon Pay, ensuring seamless deployment and integration into e-commerce platforms. - Coordinated go-live planning, monitored onboarding status, and acted as the main point of contact to address merchant concerns. - Contributed to continuous product improvement through bug tracking, feedback reporting, and collaboration with the development team. - Oversaw merchant account management and provided end-user support, ensuring smooth operations across ~200 transactions per day NPS 10/10. - Took ownership of fraud detection, a critical area of risk management, by designing and implementing an automation script that leveraged internal fraud expertise to classify suspicious payments — saving the team ~1 hour daily. - Gained first-hand exposure to the challenges of startup growth and failure, after the company ceased operations during the internship.

- Contributed to the development of a GO/NO GO validation bench for an iPhone-driven microscope used in automated medical diagnosis of mold contamination. - Collaborated in a team of three engineers to define requirements, budget, and planning directly with the client company. - Designed and developed an iOS mobile application to interface with the microscope via Bluetooth and perform validation tests. - Led the software architecture, ensuring modularity, quality, and maintainability. - Implemented the graphical user interface and developed an OCR-based displacement detection algorithm to assess the precision of the microscope’s motorized stage — a critical factor for medical-grade reliability. - Conducted code reviews and deployments, maintaining robustness across the project lifecycle. - Results showed that the device did not meet medical industry standards, leading the startup to pivot its product strategy.

- Completed a first-year engineering internship within the production line of a banking card manufacturer. - Performed quality control checks on debit and credit cards before shipment to customers, ensuring compliance with security and reliability standards. - Worked as part of the packaging team, gaining exposure to industrial workflows, logistics, and the importance of precision in high-volume manufacturing. - Observed and analyzed production processes, and proposed efficiency improvements inspired by lean manufacturing principles, contributing to workshop productivity. - Developed an early understanding of industrial operations, quality assurance, and process optimization, laying the foundation for further engineering studies.
