Where I've Worked

Senior Software Developer @ Ludopoli

Feb 2016 - Present
  • Refactored a legacy CMS application into a modular architecture, composed by a .NET Core WebAPI, a Core backend (implemented using a Domain-Driven Design (DDD) architecture, with dependency injection via AutoFac and a MongoDB Repository) and a web app using BackboneJS, MarionetteJS, React and TypeScript.
  • Created a client website that uses the above CMS, implemented with a distributed data cache system. Used Razor views, custom tag helpers, view components and TypeScript.

Some Things I've Built

Featured Project

Project Syndicate Website

Website with over 350k unique visitors a month, implemented with a distributed data cache system using MongoDB.

Has an online store where you can buy magazines and subscribe to premium content, when not subscribed you'll see a paywall. It accepts payments via credit card (using stripe) and paypal.

It also has an archive search area where you can perform simple and advanced searches (using query operators), this is implemented with Elastic Search.

  • ASP.NET Core MVC
  • Razor

Featured Project

Vismon Observer Engine

I was the tech leader responsible for the implementation of an ETL pipeline that extracted, transformed and aggregated mobile network raw data, so it could be in a more meaningful format for visual representation.

The pipeline was implemented using the pipes & filters pattern in a micro services architecture, the technologies used to achieve this were RabbitMQ, .NET Framework and MongoDB.

Elastic Search and Kibana were used to monitor the whole system, using custom made dashboards in Kibana.
