Hi! I’m Antoine Merino

I’m a software engineer based in Valence (France). I mainly work on backend systems, infrastructure, and performance optimization, and I occasionally contribute to open source projects.

Most of the content on this website is about software engineering. I may also discuss other topics I’m interested in: electronics, economics, photography, nutrition, music, etc.

See my latest articles.

If you have any comments or suggestions about an article (especially spelling mistakes!), please send me an email.

Freelancing

I’m currently available for full-remote freelance missions.

I help companies design, scale, and optimize backend systems and infrastructure, with a focus on:

• performance and scalability
• backend architecture
• database performance optimization (queries, indexing, deadlocks, query plans)
• linux / infrastructure / DevOps
• production debugging and system reliability

If you’re dealing with slow systems, scaling challenges, or infrastructure complexity, feel free to reach out via email or on LinkedIn.

You can also find some of my open source contributions on my GitHub.
