I am an experienced Developer with expertise in Tracking and specialization in Security.

Having explored different roles across an agency, a publisher, and a startup, I have confirmed a strong preference for primarily technical roles. Evolving from entry-level jobs to my last roles has demonstrated a strong ability to learn. Now, after a rich self-taught journey, I prioritize job stability and aim to grow with a company for our mutual success. I am mainly targeting fully remote positions while recognizing the value of occasional in-person meetings to foster better connections; therefore, I am also open to hybrid opportunities.

I'm the right choice for someone who values a curious and lifelong learner.

The Client-Side, Server-Side, and Workspace columns aim to simplify categorization, which may make the distribution of tags somewhat arbitrary and open to debate. While complete exhaustiveness was hardly possible, I might have overlooked key concepts or cluttered the table in my attempt to provide a detailed overview of my journey.

Highlight the most pertinent milestones, as previously, the same trajectory, but in a more descriptive and insightful way.

Following a period of personal growth and increased self-awareness, I aimed to explore my human qualities in a professional context. Through these experiences, I gained insights into my aspirations: writing code makes me happy and fulfilled. Until now, I had mostly taken service-oriented roles, which often felt misaligned with my true focus on technical excellence. I am eager to shift towards Web Development, where my technical strengths can finally shine in a role that truly reflects my skills and interests.

From September to November, at a high-growth startup, my expertise was anticipated to support the scale of an ambitious AI-powered speech-to-text API based on Whisper, Gladia. Although my technical abilities were valued, the role primarily demanded immediate leadership expertise, and the scope of client requests was broad across several entry points. This short experience was a valuable lesson; I realized that my strengths lie more in technical problem-solving than in shining at interpersonal dynamics. I thrive in environments where I can focus on delivering effective solutions and tackling complex challenges behind the scenes.

In July, I undertook a brief freelance mission as a Teacher Assistant at Jedha Bootcamp, where I provided foundational knowledge to beginners, explaining concepts to help them grasp more advanced techniques delivered by the instructors. As I needed to transition into a stable full-time position after nearly 18 months of professional development, I couldn't fully dedicate myself to a role that required significantly more time and personal investment than a part-time internship.

I followed a comprehensive path by Meta on Coursera while engaging in freelance work in a different field, focusing on React Basics and Advanced React. Learning React was particularly rewarding, enabling me to create dynamic user interfaces that significantly enhance user experience.

After reviewing my foundation in Client-side Development, I shifted my focus to Infrastructure Technologies, specifically studying Backend and Cloud Technologies on Coursera with Get Started with Cloud Native, DevOps, Agile, and NoSQL, Developing Back-End Apps with Node.js and Express, and Containers with Docker, Kubernetes & OpenShift by IBM, along with NoSQL by MongoDB. I was driven to engage with Cloud-native Development, an essential approach for building scalable applications today.

Recognizing that Information Security requires extensive expertise across all software, languages, and environments, I considered my interest in Penetration Testing. While I remain stimulated by the field, I prefer contributing to the development of solutions that have a long-term impact and address specific needs rather than engaging in the often abstract and complex nature of Vulnerability Assessments. I decided to capitalize on my existing knowledge and pursue what motivates me the most: writing code and designing efficient logic. I revisited my fundamentals to solidify them through Coursera with the courses AJAX for Web Developers, Modern JavaScript Iterators and Generators, and the Intermediate Web and Front-End Development pathway by IBM.

Theoretical courses, practical exercises, and continuous assessment were essential during and after the initial bootcamp to forge my understanding of the concepts. On TryHackMe, I completed the courses Introduction to Cyber Security, Pre Security, and Web Fundamentals, followed by the Jr Penetration Tester path, of which 90% was completed in 2023 before prioritizing studies in Cloud Technologies and Web Development. Determined to see it through, I achieved it in April 2024 after a thorough review. I also spent a few days on Hack The Box.

From the first weeks of the bootcamp, I was immediately challenged with critical topics that required rapid skill acquisition. Each day in parallel on Coursera, I followed the Specialization in Python for Everybody by University of Michigan, and then completed Introduction to TCP/IP by Yonsei University. I also began the Technical Support Fundamentals path by Google to gain knowledge in hardware concepts, which I have paused for now.

At Jedha Bootcamp, I focused on Kali Linux for Vulnerability Assessments, supported by courses and guidance from instructors who provided a hands-on approach through various labs. The program offered an in-depth exploration of Web and Network Security, equipping students with a solid understanding of Firewalls, VPNs, and Intrusion Detection Systems. It covered Penetration Testing techniques and tools such as Burp Suite, Nmap, Metasploit, and Wireshark, as well as numerous command-line tools accessible from GitHub. Additionally, I acquired knowledge in Incident Response, Threat Analysis, Forensics, and Open Source Intelligence.

Having proactively managed administrative tasks to start my training as soon as possible, I spent the last few weeks on Coursera refining my foundations with Command Line Basics in Linux, discovering Introduction to Bash Shell Scripting, and exploring Practical Vim Editor Commands on Linux (anticipating scenarios where interaction with this editor is the only option).

Hired as a Consultant at Commanders Act, which has evolved into a Customer Data Platform since, I was offered the opportunity to join Support due to my Frontend and Analytics expertise. I provided guidance on implementation choices, needs analysis, debugging, diagnosis, advice, solution proposals, Responsive Web Development, and processed routine tasks in Account Access Management.

Given the diversity of environments and the constant evolution of third-party libraries, editing or adding custom JavaScript in Data Collection is often necessary. Since every Tag Management System, including TagCommander, only covers the most common use cases, adding advanced logic to meet specific needs is essential. I provided clean, efficient, and easy-to-maintain code, which has contributed to the smooth operation of the company by assisting clients and consultants with their configurations.

The intricacies of consent cycles and triggering third-party solutions, along with Google Tag Manager specifics, make any implementation complex. Questions were frequent, and documenting this topic met many expectations to facilitate the adoption of TrustCommander, the Consent Management Platform, in accordance with CNIL and GDPR requirements. The document TrustCommander into Google Tag Manager proved useful for many clients, streamlining the work of internal consultants. I simplified concepts during dedicated sessions when needed, receiving excellent feedback.

To address the recurrence of topics (routines, common issues, or industry changes) and free up time for more advanced resolutions, refine responses, and eliminate errors, I took the initiative to optimize. To maintain a collection of text responses and JavaScript codes aimed at continuous improvement with versioning, I created a private repository on a dedicated GitHub account. Although I had accumulated the files, this personal solution required a collaborative approach to be completed. I handed over all the files to the Product Owner upon my departure.

The data agency fifty-five, founded by former Google Europe executives, aims to help major players leverage their data. As a Tracking Specialist, I quickly expanded my role and was entrusted with projects in Conversion Rate Optimization, requiring Responsive Web Design skills and my expertise in JavaScript. To support my growth, I completed online courses primarily on Google Tag Manager and Google Analytics. I also studied UX to refine my A/B Testing skills and, thinking about the future, AWS to enhance my strengths as a Web Developer by exploring EC2, AMI, ELB, EBS, S3, IAM, Route53, and Lambda.

Some logics are sophisticated, and Tag Management Systems are used by profiles not familiar with JavaScript, such as marketing teams. My former manager suggested exploring a documentation generator to provide detailed information on specific functions. I delivered a Node.js app coupled with a REST API, using JSDoc to generate documentation about the JavaScript enhancing Google Tag Manager. This involved refactoring the existing code before development to enable the use of Annotations, and also writing explanatory descriptions. The project was approved and praised by the CTO.

Consulted for a major modification of the Renault France homepage, the agency's most important client at the time, I confirmed the feasibility of a test involving data spread across different pages. After determining the possibility of cloning elements from product pages in Local Storage and reconstructing them by integrating CTAs (Call to Action) and Tracking (along with creating Google Analytics segments), I structured the required JavaScript into different Google Tag Manager tags within a precise scope to avoid impacting performance. Interactive and engaging, displaying vehicles viewed during the active session (and previous ones) before any other content, the experience showed a significantly higher conversion rate than the control version, leading the client to commission new Conversion Rate Optimization experiences for a substantial amount.

Tag Management Systems facilitate the orchestration of third-party solutions by providing an entry point through a container script, but they only cover the most common cases. I offered simple and reliable solutions, with numerous JavaScript snippets to address various needs.

Following a 3-month Web Development Bootcamp with WebForce3 (covering the basics in HTML, programming with JavaScript, procedural and object-oriented PHP, MySQL, Git, Bootstrap, and more), I delved deeper into each subject for over a year on the online platform OpenClassrooms to fully grasp the concepts (completing numerous certificates, each consisting of lessons, quizzes, exercises, and a final assignment). Pushing through Eloquent JavaScript 3rd edition (2018) while job hunting was key to securing my first role.

As a capstone project, I developed a CV website using Symfony 3, my very first online application. While I don't recall the hosting provider, I remember configuring an Apache HTTP Server. I also implemented a messaging feature with jQuery and SQL, allowing users to chat, along with a timed game where players had to drag and drop bills into a bank while avoiding a controller that would decrease their score. The responsive frontend was created with custom CSS. Although I didn't keep the code from that time, you can visit an archive of sylvaindemaimay.com/sitemap on The Wayback Machine (Texts in French), where I expressed a strong interest in security and the potential of data. My curiosity and commitment to understanding these areas have guided my career development, rooted in documentaries on societal subjects and science fiction films that offer inspiration with a prospective view.
