My journey in the world of software development has been marked by continuous growth and a passion for solving complex challenges. I've evolved from a Lecturer in web development to a Tech Lead Software Engineer, gaining expertise in various areas along the way. A significant milestone in my career was my role as a Senior Backend Developer / DevOps at Webedia GmbH. There, I not only mastered Ruby on Rails but also improved and configured recommendation systems, elevating user experiences to new heights. In another role as a DevOps / Platform Engineer at anynines, I excelled in automated PaaS management and introduced microservices architecture using Ruby and Golang. My knack for system automation and PaaS application support contributed significantly to the organization's efficiency. Throughout my journey, I've embraced cloud infrastructure, DevOps practices, and leadership roles. My unique skills lie in bridging the gap between development, infrastructure, and system automation, enabling me to tackle challenges that others may find daunting. I'm not just a developer; I'm an innovator who thrives on continuous learning and finding creative solutions in the ever-evolving landscape of technology. With 15+ years of industry experience, I have a proven track record in leading large teams, designing innovative systems, and making significant contributions to the industry. I am well-equipped to set and direct departments and contribute substantially to any challenging projects.

I've been programming since I was a young teen, earned two bachelors degrees from MIT (Computer Science, Electrical Engineering), and I bring an A+ game when it comes to crafting software. My training and broad experience enables me to steer architectural and software design choices. I take pride in mentoring junior- and mid-level developers. I present solid, but flexible, opinions when collaborating with other engineers, and I cultivate those opinions through continuing education and broad experience. Some highlights: • Recruited and led the development team that turned around the National 4-H web application, from a struggling and seldom-used administration tool to a full-featured app used in 25 states at the state, county, club, and member level. • Created a custom product-description language and accompanying web application that allowed a client to create new workflow-based products. The client increased their product offerings by 10x and their volume-per-staff by nearly 10x. • Developed two new web applications for a Colorado municipality to offer fiber internet to their residents. The web applications were used by thousands of customers to sign up, schedule installation, and pay for service, and by the installers in the field to activate new commercial and residential installations. The web applications had to integrate multiple third-party systems and custom databases in a set of robust, fault-tolerant, and transactional processes. • Engineered and developed the noise analysis tool used to validate the integer processing unit (IPU) of Intel's Pentium 4 processor. • Filled a wide spectrum of roles on many large projects, from single engineer, building and launching greenfield web applications, to project team leader managing multi-engineer projects. • Mentored junior- and mid-level developers, helping them earn promotions. Mentored teams by steering team culture through regular show-and-tell sessions and a technical book club.

🚨 Info Alerte !!! 🚨 Vous ne le saviez peut-être pas, mais 👀 C'est bon, maintenant j'ai votre attention. Bienvenue sur le profil d'un développeur web qui n’aspire pas simplement à faire du code, mais avant tout à vivre une aventure humaine, professionnelle et pleine de défis. Ce que vous devez savoir à mon sujet : 💼 Mon expérience dans le secteur bancaire m'a doté d'un sens aigu de la rigueur et de l'organisation🗄️. J'y ai appris à être méticuleux et à gérer efficacement mon temps. Dans le domaine des télécommunications, j'ai développé des compétences relationnelles et en communication 🗣️. Cela m'a permis de travailler avec des équipes diverses et de trouver des solutions rapides et efficaces. J'ai été confronté à des situations variées où gagner en autonomie, faire preuve de clarté et avoir la capacité à trouver des solutions rapidement était essentiel, et j’aime ça. Alors pourquoi le développement web ? 🤷🏽‍♂️ Les raisons sont les suivantes : La première, j'ai toujours aimé tout ce qui était en rapport avec l'informatique. La deuxième, c'est la capacité de pouvoir transformer une idée en partant de 0, en quelque chose de réel et impactant. Chaque ligne de code représentant la solution à une problématique. C'est pour cela que je me suis lancé dans le développement web, afin de participer à la construction de projets innovants. 🚀 C'est avec hâte que je souhaite relever des défis stimulants à venir, prêt à sortir de ma zone de confort pour que nous puissions atteindre un objectif commun, le tout dans la bonne humeur 😁.
