About Mariot

Software Architect & Performance Expert – I boost your software and your data

Looking to speed up your applications, optimize your data pipelines, or launch a robust first version of your software to convince your clients or investors?

I help you move from idea to concrete demonstration, ensuring high-performance, scalable solutions tailored to your business needs.

What I bring you:

✅ Performance Improvement: Audit, code optimization, latency reduction, bottleneck management.

✅ Reliable Data Pipelines: Design, implementation, and automation for smooth and actionable data flows.

✅ Prototyping and MVP: Development of the first version of your software, ready for client presentation or fundraising.

My difference?

I combine the technical expertise of a software architect (design, best practices, technology choices) with the agility of an experienced developer to deliver operational solutions, quickly and without compromising on quality.

Usual project types:

- Optimization of slow or resource-intensive applications
- Creation of ETL/ELT pipelines for analytics or machine learning
- Development of PoCs or MVPs to validate an idea
- Architectural refactoring to prepare for scaling
