ABOUT ME
Polyglot programmer experienced across the stack (Front-end, back-end, infrastructure, databases, automation, security and testing)
Polyglot programmer experienced across the stack (Front-end, back-end, infrastructure, databases, automation, security and testing)

Experienced software engineer focused on backend development with complementary experience in data engineering, frontend, DevOps and infrastructure.

I worked mostly on data-intensive products, in cross-functional teams collaborating with product owners, data scientists and UX designers. Solving problems in complex distributed systems.

I love to help teams achieve continuous delivery of valuable software. To achieve this I focus on four areas:

- Agile, Lean and DevOps principles

- Architecture and system design

- Quality and Automated testing

- Collaboration and mentoring.

One of the projects I built with React is a data visualization application where user can select, slice and dice data they want to show and could also display the results in different ways. I also have experience building admin system on React/Redux as well as building different types of technical management systems on Redux/Mobx.

I've used D3.js for dashboards with different graphs fulfilling all kinds of client need. I've created simple graphs to complex graphs showing real-time data such as a world map which shows where articles about terrorism attack are published or a graph that shows how sentiment (positive/negative) evolve overtime on a specific subject.

SLB is a global technology company in the energy industry. I worked on three different product teams creating applications allowing geophysicists to analyse geological data at scale. These systems were composed of 5 to 20+ micro-services.

Examples of achievements:

- Collaborated with data science to integrate data pipelines (log splicing, ..).

- Designed and implemented a system to identify rock layers in 100k logs and compute properties on them.

- Improved performances on quality metrics filtering by switching to a more appropriate database.

- Plotting millions of data points based on a live query in less than a minute using Spark.

Signal AI is an applied AI company which aggregates thousands of news sources and provides applications for organisations to monitor their brand and their industry in the media. I have seen the evolution of Signal from being the first employee (working from a garage) with no clients to raising several rounds of funding (Seed, Series A and B, $27M in total), selling to hundreds of clients (among them big corporations like Deloitte, HSBC or British Airways), reaching 100+ employees and generating $10M ARR(Annual Recurring Revenues) in the space of 5 years. I worked in a cross-functional (UX, data science, engineering), highly collaborative, lean/agile team focused on delivering value.

Examples of achievements:

  • Collaborated with UX designers (brainstorms, user interviews...) to develop the main user-facing product which allows people to construct complex queries on a large dataset and represent the data in a shape that allows them to dive in and draw insights from it.
  • Collaborated with Data Scientists to integrate several AI/Machine Learning services in production systems (Article clustering, quotes detection, sentiment).
  • Made our email alert system scalable and resilient to respond to the growth of our client base and be able to perform thousands of searches every minute to deliver our alerts “instantly” and beat the competition.
  • Added new content that increased the load on the system by 1.5 million articles a day involving setting up monitoring and making sure the system scales up accordingly.
