Back to original languageAbout Adrien
I fell into PostgreSQL in 2014 and since then, this open-source DBMS has stayed with me :)
I acquired a good knowledge of the engine and SQL at Dalibo, which I used in my consulting tasks. These ranged from training to engine tuning, including participation in the PostgreSQL community (conferences, open-source projects, writing articles, writing and reviewing patches for the engine itself...).
I complemented these skills at Doctolib with solid experience in maintaining a large, high-traffic production environment with significant stakes in terms of performance, security, and service availability: ~45,000 transactions per second on a database of over 3.5TB with very strong growth.
Since 2021, I have been available for freelance missions:
- Audit/consulting and architecture consulting
- Engine and operating system (Linux) tuning
- Remote DBA
- Query optimization, execution plan analysis
- Modeling consulting
- Backups
- Physical and logical replication
- Training
- Cost reduction with cloud providers
- Advanced PostgreSQL uses: partitioning, Full Text Search, indexing strategies...
Over the years, I have gained experience through the multitude of environments I have worked on: cloud, application stacks (Python Django, Flask, SQLAlchemy, Ruby On Rails, Hibernate...).
I am also keen to maintain my involvement in the PostgreSQL community. Thus, you can meet me at community events (conferences, meetups...) as well as on Postgres mailing lists ;)
They trusted me: Alma, Engie, Radio France, INA, Paris Hospitals (APHP), DGFIP, Mirakl, Welcome to the Jungle, Frisquet, Acoss, Plum Energie, Major Corp, Foodles, Julaya, Europ assistance...
