About

I'm the founder and lead developer at Mataf, a Fintech company (trading platform, tools & community) I worked on several projects from SaaS application to large website with millions of pages in several languages. I'm a developer who likes to work on complex projects and doesn't like humdrum routine work. My area of expertise is development in web environment: I work on a web application from the back end to the front end. I'm also comfortable with system administration, a kind of devOps-ish. I'm autonomous, I listen to other. I'm curious, I like learning and, above all, apply what I learned.

Technologies I use on a daily basis (not just a list of keywords):

  • 15 years experience with PHP and Javascript. Good abilities using HTML5/CSS.
  • OOP - DRY, Dependency Injection. MVC.
  • REST APIs - Server and client. JSON and XML. HTTP request/response.
  • High availability, speed - code optimization, Memcache, CDN
  • Mobile - touch interface, UX, Server side development for mobile app. Prototyping with React Native
  • Algorithm - real time calculation on financial data
  • LAMP - Linux (Debian), Apache, MySQL/MariaDB (Galera Cluster), PHP (Functional and Object Oriented Programming).
  • Very good understanding of SEO, Marketing, A/B testing

Data

data

For each project I work on, I have a data-focused approach. When I trade, I analyse every statistics as the win rate, the impact of market volatility on my performance, the correlation between assets... When I make a change on an application, I implement relevant KPI, I measure the effect with A/B testing... Even when I make an investment, I collect all the data about the market and make a full risk analysis.
