Senior Front-End React Engineer
Two Sigma, Permanent
- React
- TypeScript
- Styled Components
- Node.js
Front-End engineer on Two Sigma's Venn platform.
Venn is a platform that makes it simpler to select managers, choose assets and manage risk, via Two Sigma's factors analysis.
On the technical side, the front-end was originaly written in JavaScript (ES6), React, Redux, Redux-Saga and SCSS (with CSS Modules).
It was then rewritten to TypeScript, replacing Redux by React's context and more local state. We also replaced SCSS and CSS Modules by Styled Components.
Part of the original team of 2 Front-End developers, I was able to play a decisive role on the original architecture and then the rewrite of the application.

- React
- Redux
- AngularJS
- Node.js
Front-End developer on RBS’ flagship platform “Agile Markets”.
Implementation of several modules, from FX options tickets (Peg, TWAP, OCO, IDO…) to analysis tools.
These modules were developed using React, AngularJS, or plain JavaScript (with D3) depending on the requirements.
They are connected to back-end services using REST endpoints and websockets (Caplin), and tested using Mocha or Karma against a Node server.
These projects are built using Grunt, including some custom Grunt tasks. They are highly modularised, using Stash / Git for source control.
Webpack is going to be introduced soon, and I will be trialing the technology.

Over 5,000 unit tests have been written for this application, using frameworks such as NUnit, Moq, SpecFlow and Selenium.
The web application was originally written in classic ASP.NET and then (partially) migrated to MVC 3 (Razor), and ExtJS (Ext.NET).

The back end is C# 4 with NHibernate as the ORM (using Fluent NH for the mapping).
The server side is using my open source project (http://fta.codeplex.com) as a base for the data access layer.
The Dependency Injection framework used for this project is AutoFac.

Royal Bank of Scotland, Contractor

The Silverlight based software is used around the globe to manage RBS and its subsidiaries contracts and allows netting calculations.
- The client is based on Silverlight
- The server is C# 4 based
- The communication between the client and the server is based on WCF (binary serialisation)
- The data access layer is using NHibernate, with attribute-based mapping
- The changes in the database schema are managed by Migrator.NET
- Entities to DTOs mapping is done using AutoMapper
- The Dependency Injection framework is AutoFac
- The Silverlight UI is using Infragistics for the ribbon and other controls
Aspect oriented programming (AOP) is also used to manage NHibernate sessions (transactions), using the PostSharp framework.
The development environment is based on a stack of well-known open source products such as:
- CruiseControl.NET and NAnt for the continuous integration
- NUnit for unit testing
- log4net for logging
- Rhino Mocks for unit test mocking
The Agile methodology was used throughout the life time of the project, with a 10 minutes stand-up meeting every morning, regular retrospective meetings, Test Driven Development (TDD) was also enforced and code reviews were done before each commit.
I have also scored 100th percentile (worldwide) on the Brain Bench test while applying for this contract.

Full-Stack Developer, Architect
BNP Paribas - FundQuest UK, Full-Time
- ASP.NET
- C#
- NHibernate
- MySQL
Design, implementation and maintenance of a Quantitative, Document Management and Trading Web Application.
The system is a complete architectural redesign of an existing intranet, after assessment of its flaws.
This Web Application serves 3 main purposes, and 3 categories of people:
- Quantitative analysis tool (for Quants) (Performance reports, custom graphs, funds management, peer groups, statistics)
- Document management (meeting and research notes, attachments, full text search on content, complex search facilities)
- Trading system (Management of all FundQuest UK trading, reports, portfolio valuations, links with some electronic trading systems (EMX)) These are some of the areas of the system that I've been designing:
- Core architecture: I brought NHibernate for the Data Access Layer, and pushed for the use of a source control tool (SVN), along with a Unit Testing tool (NUnit)
- Performance: The most challenging aspect of the application: all the calculations are made on the fly, using a combination of caching, high-performance stored procedure, and pre-fetching of information
- Charting: I've introduced Dundas Chart, and implemented most of the pages using this library
- Web Pages: I've introduced the use of master pages, as the previous project was using frames
- Security: I made most of the pages viewable in a "read-only" mode, with a combination of techniques I designed
- Documents: All documents can be linked to any entity (funds, users, universes...), and all their content are indexed

The programming methodology used was Agile (Scrum), with 3 months cycles and 2 weeks iterations.
We also used the continuous integration procedure (CruiseControl.net).
