Hi there

My name is Esteban MATHIA, a passionate software engineer currently working at Innovtech. I'm an active member of several organizations and actively contribute.

In addition to my love of technology, I am also interested in sport, games, and martial art.

Below are details of some of the projects I have developed over my years of coding experience.

Projects

Kexa & Kexa SaaS

2023-

• TypeScript
• Vue
• Observability
• Monitoring
• Security
• PaC
• Web Dev
• CNCF
• OpenSSF

Development and deployment of Kexa, an innovative open-source solution simplifying compliance management on multi-cloud platforms (Azure, Google Cloud, AWS, etc.). Thanks to intuitive, customizable rules, Kexa enables even non-experts to ensure the security of cloud environments, while guaranteeing near real-time monitoring and instant alerts in the event of non-compliance.

This open-source project that I initiated respects the OpenSSF development standards. I work on all the different aspects of the project, from design to production.

Codingame

2022-2024

• AI
• Typescript
• Python
• C++
• Rust
• Golang

Over the course of more than 10 months of daily commitment to CodinGame, a competitive programming platform, I reached 75th place in the world, ranking among the "Grand Masters". My journey began with no specific goal in mind, but the challenges of fighting bots quickly captured my interest. By accumulating 9 legend leagues and several gold leagues, I honed my skills in code optimization and complex problem solving. This constant work, combined with the use of several programming languages (Python, Typescript, C++, Rust), has enabled me to push back my limits and rank among the world's top developers. I'm still actively involved in the CodinGame community, taking part in challenges and helping to approve new content.

My Codingame Profile

Solatria

2024

• TypeScript
• React
• Azure
• MongoDB
• Mathematical

As Lead Technician, I led the development of a solution to carry out feasibility studies for new solar panel supports in B2B context, complementing the existing range of the compagnie to penetrate new international markets. The aim of this project was to meet growing demand by optimizing the commercial approach.

To achieve this, I designed an intuitive web application enabling users to quickly create projects, analyze the site environment, draw roof sketches and select suitable components. The tool produces detailed reports, parts lists and quotations to facilitate the management of solar installations. This replaces the work of the design office, which can take several days to complete in just a few minutes.

The CloudPrices

2022-2023

• TypeScript
• C#
• Vue
• Azure
• Kubernetes
• Micro-Service
• Finops

The aim of TheCloudPrices project was to inventory the prices of cloud services from the three main providers: Azure, AWS, and GCP. To achieve this, I set up microservices dedicated to data scraping, resource benchmarking and information processing to feed our databases in an automated way.

This website served as a decision support and FinOps management tool, enabling companies to optimize their cloud spending. Thanks to our solution, our users were able to achieve savings of 50-70% on the cost of virtual machines, while maintaining and even improving performance.

ISEE

2022

• TypeScript
• Python
• React
• Azure
• Micro-Service
• AI

As part of this project, I designed robust APIs for a video-sharing web platform, with a strong focus on software architecture and scalability. The APIs are scalable and have been designed to efficiently handle growing loads and extended functionality. The management of users, videos, comments and administration functions is based on optimization techniques that guarantee high performance and enhanced security.

To enhance the user experience and increase engagement, we have integrated clustering AI, enabling personalized content recommendations. By analyzing user behavior and preferences, this AI groups similar videos according to dynamic criteria, to offer relevant recommendations. This intelligent system continually evolves with new data sets, making the recommendation algorithm more powerful as the platform develops.

Monopoly

2021

• Python
• React (& native)
• Typescript
• IA
• Cross-platform

I create with a mate a digital Monopoly game that allows users to discover Normandy while having fun. The game includes an online mode and messaging system with a matchmaking and ranking system, offering the possibility of playing with friends or meeting new opponents. For those who prefer to play solo, we've developed high-performance AIs, available in three difficulty levels, guaranteeing an experience suited to all types of player.

The application is fully cross-platform, ensuring compatibility on all types of computers and operating systems. Thanks to this approach, we have been able to create a fluid and accessible gaming experience, whether for casual or competitive use.

This represents just a small selection of the projects I have worked on over the years. I have many more pieces of personal, university and professional work.
