About

🚀 Backend Developer specialized in Golang – I help startups / scale-ups develop high-performance and scalable backends to support their growth Hello, I’m Guillaume, a backend developer with over 15 years of experience. My expertise is focused on Golang, the perfect language for creating high-performance, scalable, and reliable systems. 💻 What I do best: - Backend Development: Creating robust architectures with Golang, gRPC, integrating and developing APIs (RESTful), and designing high-performance databases with PostgreSQL and MongoDB. - Microservices: Building scalable and resilient systems for startups and scale-ups. - Productivity & Performance: My strength is delivering quickly and efficiently. I optimize processes to help you achieve your technical goals faster. - DevOps Practices: Automation with CI/CD (GitHub Actions, GitLab), containerization with Docker, orchestrated deployments with Kubernetes. 💼 What I’m looking for: - Golang backend remote projects: Ideally, projects where I can have a direct impact on product performance and reliability. - Collaborating with startups/scale-ups: Companies looking to build or evolve their backend stack, and who value autonomous and productive profiles. 🤝 What I can offer additionally: If I can’t help you directly, I can connect you with my network of experienced developers. 💡 Entrepreneurial side: I founded SignalWhisperBot, an innovative SaaS service that transcribes voice messages on Signal to improve productivity. Available in freemium, it’s the ideal solution for those who want to save time on communication. Try it for free here: https://signalwhisperbot.com/en ✨ Open to ambitious projects: Passionate about technical and entrepreneurial challenges, I’m also interested in collaborating as a co-founder on a SaaS project.
