About Lucas

Senior Backend Developer & DevOps | Expert Python, Kubernetes, Scalable Architecture

With over 10 years of experience, I transform complex infrastructures into robust and scalable solutions. Specialist in high-availability environments, I optimize performance where others see limitations.
I solve the technical challenges you've been putting off for too long:

Python APIs (Django/FastAPI) handling millions of daily requests
Migrations to Kubernetes with automated deployments via GitLab CI
PostgreSQL/MongoDB database optimization for increased performance
Strategic transition between microservices and monolithic architectures

I am not just a developer who writes code – I am an engineer who understands the business implications of your technical decisions. My pragmatic approach aims for measurable and sustainable results.

Immediate availability for:
✓ Strengthening your team on critical projects
✓ Optimizing your existing infrastructures
✓ Implementing efficient CI/CD pipelines
✓ Conducting technical audits and architecture recommendations

Contact me to discuss how my skills can meet your current technical needs.
