My Bio

I’ve been Full-stack .NET Software Engineer for 12 years working with .NET since its version 1.0 and Visual Studio 2003. I’ve worked in permanent and contract roles for 9 New Zealand and 7 Brazilian companies developing from small to large software to solve problems from different industries like Investment Banks, Health Insurance, Accounting Software, Oil and Gas Industry, etc.

I’ve got a strong knowledge of building Resilient, High Availability and Scalable Services using technologies like Windows Azure, .NET, C#, Web API, Windows Services, Service Bus, Queues, Service-Oriented Architecture (SOA), Event-driven architecture (EDA), Domain-Driven Design (DDD), SOLID principals, NoSQL Databases, Asynchronous Programming in C#, Caching Mechanism, Eventual Consistency, CDN, Master-Slave Architecture and Load Balancing.

I really love what I do, and my work is my second home. Even after work, I like to keep myself updated with the existing and new technologies using mainly online training courses like Xamarin University, Pluralsight, Lynda, Code School, Channel 9 and so on. I like to apply my skills in personal projects that I use as a proof of concept before applying in large projects.

In my spare time, I like to play soccer, guitar, catching up with friends for a BBQ and working out at the gym.

Progressive Enterprises – New Zealand (http://www.progressive.co.nz/)
Progressive Enterprises owns and operates over 183 Countdown supermarkets in New Zealand. They are the New Zealand’s largest private sector employer, with 18,500 employees.

• Key technologies: Service-oriented architecture (SOA), .NET, C#, ASP .NET Web API, Services Bus, Queues, Windows Services, ASP .NET MVC, Jquery, Kendo UI MVVM, Html, CSS, SQL Server, ElasticSearch, Splunk, TFS, Unit Tests, Moq, Fluent Assertion, AutoFixture, Continuous Integration with Visual Studio Team Services and Agile methodology.
• I developed a software integration between Countdown Supermarkets and AA Smartfuel (Fuel Savings & Discount Programme) which benefited over 3.5 million customers in New Zealand. Both companies used to have two different loyalty cards, and they joined to create only one card, and now all customers from both companies can get discounts and electronic vouchers when they shop at Countdown supermarkets and BP and Caltex petrol stations all over New Zealand.


- Countdown: https://www.countdown.co.nz/onecard
- AA Smartfuel: https://www.aa.co.nz/aasmartfuel/

• We implemented SOA architecture/Microservices using NServiceBus, Windows Services, Message Queuing (MSMQ), ElasticSearch for caching and ASP.NET Web API.
• We exposed some of our data externally to AA Smartfuel using Web API with Bearer Token Authentication, and we also had a queue in place to receive the supermarket's transactions to calculate all the customer points and benefits.
• We refactored the previous loyalty points solution from 3-Tier Architecture to Service Oriented Architecture. Now, this new solution is driven by messages, and the business logic sits behind a Web API following the Domain-Driven Design (DDD).
• All of those are integrated with Splunk to generate logs, charts, reports, and alerts.
• In case we have exceptions when processing a message, we had a Retry Design Pattern and Circuit Breaker in place, but in some rare cases, the message goes to a dead letter queue which can be manually retried later by the support team.
• We cache some of our data using ElasticSearch to speed up the micro services when accessing data which gets used frequently and don’t change very often.
• All Web APIs and Microservices had Unit Tests protecting the code against new changes to the solution.
• I was one of the main Sr Software Developers working directly in all parts of the architecture described previously.
• I’ve also added new features to the existing Customer Services web application using ASP.NET MVC, JQuery, and Kendo UI MVVM.
