Senior .Net Developer

7/2020 – 9/2020

During this time our company had the intent of participating in a competition for a European funded contract for the city hall, developing a big online platform (microservices) for automating many internal and public bureaucratic processes (for civil servants and common people alike).

Myself, together with another colleague, worked as Solution Architects in a bigger team of experts (of UX, Business Analysts, DevOps) being responsible for analyzing the requirements, risks and deadlines of the project. Our main job was to drive the technical direction for the discovered domains and map them to viable solutions in terms of infrastructure, frameworks and libraries.

We eventually got to materialize some of our ideas as a tech proof of concept, where we tried out the latest tech in container orchestration (Docker + Kubernetes) and investigated solutions for other common aspects that come up in big microservice architectures (Traefik, Kong - as API Gateways, KeyCloack - for authentication and integration with other OAuth2 providers, GRPC, Service Meshes in Kubernetes, Kafka and RabbitMQ, WorkflowEngine frameworks)

Drug Market Access, Pharma Industry

The core use case of the application is to navigate meeting the numerous and diverse requirements for a drug to get multinational market approvals, and also follow reimbursement opportunities.

● The client redesigned the way user management had to be done, move away from global user roles to resource based policies. This required rethinking the authorization to be simple and flexible enough to support all the new requirements and don't degrade performance.

● Tests were getting harder to write, morale for doing TDD was very low. I have introduced a new strategy for integration tests.
My objective was to increase the value and coverage of the tests, to comprise DB querying as well.
I have done this using by using an in-memory DB for Entity Framework 6, and simplified writing tests by leveraging the existing Dependency Injection framework and introduced a fake data generator. My team mates expressed that this was the most seamless experience for writing tests they have ever had.

● Introduced a CQRS approach by using Mediatr.

● Migrated to a long term release version of AngularJs

Drug Development, Pharma Industry

The Web App was helping organize drug development, related activities and resources.

As a Backend Developer I contributed in co-architecting and implementing the multi-tenancy, data isolation and security aspects of the application.

Online Virtual 3D Shop

This project was interesting because the front end of the web application was in Unity.

It was important for the client to increase user retention rate and first time experience. We had to try every trick in the book to speed up loading times.

The cllient also wanted to improve SEO and relevance of in-app searches, thus I initiated the idea of using ElasticSearch, got accepted and implemented.

Because the we were running on Linux and the solution was expanding to use other services and tools, I made the proposition of using Docker, to simplify deployment

Released Disco Dave, a multi-platforms mobile game

Together with the Game Designer and Artist, we have release Disco Dave on IOS and Android.

The game was a success. It was chosen by Apple for being featured in the App Store, and we had delivered it according to estimations.

My contribution was to architect and implement areas like: app lifecycle, game management, screen management, ads, notifications.

Educational Trivia Game

We used Linux to develop the game in C++ and Lua, eventually targeting the Android and IOS architectures.

Libraries: SLD2

C++

9/2012 – 3/2016

Worked on a 2D online cross-platform mobile game for the studio.
During this time we were building on top of our own game engine. Aside from working on game features, I was mainly tasked with implementing the engine's features across Windows, IOS, Android, even Windows 8 at one point.

While being responsible for compiling the C++ code base (engine and game) across all these platforms, with various compilers (MSVC, GCC, CLANG) I've had experience coding for platform-independence and performance; design from a library-writter perspective; and not trust that C++ specs get implemented equally across compilers.

Introduced CI responsible for IOS and Android builds.

More precisely, I have coded with DirectX, OpenGL, OpenGL ES, Objective-C, Protobuf, and every platforms APIs for lifecycle, notifications, networking, file-system access.

C++, DirectX, OpenGL

3/2012 – 8/2012

The project consisted on porting a popular online mobile IOS game to Windows phone.

By porting the game and equivalent platform features we got experience with OSX, XCode and Objective-C apis.

As a Front End developer on the project I had the responsibility of creating rich UI dashboards for a backend managing server clusters.
