Freelancer profile translated to English.

Description

Software engineer with over 14 years of experience, I work on technically challenging projects as a senior developer and technical lead. My expertise covers back-end technologies (Python: FastAPI, Django, Flask / PHP: Symfony, Laravel), modern front-end interfaces (Angular, JavaScript ES6+, Backbone), as well as the entire CI/CD and DevOps chain.

💼 Areas of intervention:

🔧 Design and development of robust and modular back-end architectures

Specializing in REST APIs and microservice architectures, I design scalable, well-documented, and tested systems, incorporating hexagonal architecture or DDD principles when necessary.

🧭 Technical Lead

Leading tech teams (scoping, code review, defining technical roadmap), upskilling developers, sharing best practices, audits, and architecture choices.

💻 Front-end development

Development of dynamic and responsive interfaces in Angular, with particular attention to performance, accessibility, and usability.

⚙️ DevOps Practices

Implementation and management of CI/CD pipelines using GitLab CI or Jenkins, containerization with Docker, monitoring with Datadog, Kibana, cloud deployments with AWS (Lambda, S3, SES, SQS).

🚀 Agile Project Management

Working in Scrum/Agile methodologies, in close collaboration with product, QA, DevOps teams, and business stakeholders to ensure coherence, delivery, and quality.

🌐 I have worked in various environments – e-commerce, telecom, banking, media/tech – consistently bringing strong technical value, rapid adaptability, and constant attention to solution scalability and maintainability.

📚 Passionate about software architecture, code quality, and knowledge sharing, I actively stay updated on modern software development practices.
