Freelancer profile translated to English.

Description

Hello and welcome to my profile!

I have been an IT professional for over twenty years! Already :)

Over the years and through my numerous client experiences, I have acquired a rich and strong expertise in databases, in stand-alone environments or on more complex architectures with the implementation of high availability, which I use in my daily tasks as a consultant.

The engines I have worked with:

- PostgreSQL

- Oracle

- SQLserver

- IBM DB2 Z/os and LUW

- MongoDB

- MySQL/MariaDB

- ElasticSearch

- SnowFlakeDB

Therefore, I am available for freelance missions:

- Audit/consulting and architecture consulting

- Database administration

- Remote DBA

- Query optimization, execution plans

- Connection pooling

- Modeling consulting

- Backups/Restoration

- Physical and logical replication,

- PATRONI, ETCD, HaProxy, IBM HADR, Oracle RAC and Dataguard, AlwaysOn

- Advanced uses of postgres: partitioning, Full Text Search, indexing strategies...

Besides that, I remain curious and interested and am gaining experience through recent training on topics related to DATA and ML: Cloud, Python, Numpy and Dataframes, DBT, AirFlow, ETL, ELT, Scikit-learn,...)

See you soon !
