Description

Looking for a partner to help you implement and optimize your data pipelines and backend systems?

👉 With several years of experience in Java development and Data Engineering, I help organizations of all sizes manage and leverage their high-volume data.

In a context where data reliability and performance are becoming a strategic issue, robust systems are essential. Many companies lose efficiency due to slow batches or unstable microservices, which can lead to wasted time, application malfunctions, and low productivity.

Through my expertise, I help you solve these efficiency problems and implement strategies that ensure the availability and performance of your systems. My role is to provide you with clear solutions tailored to your needs, while guiding you in creating reliable data pipelines and optimizing infrastructure to guarantee concrete and sustainable results.

What I offer:

✔️ Design and optimization of Java batches (Spring Batch) for large-scale data processing.

✔️ Implementation of microservices architecture and their monitoring (Kibana).

✔️ Redesign and optimization of SQL queries to reduce loading times and latencies.

✔️ Implementation of MLOps and CI/CD processes to automate deployments and improve quality.

📩 Contact me by DM or email () to discuss.
