Backend Team Lead

•  Acted as the Technical Leader for the Trigger Publisher API work in Red Button 2020 (RB2020) where I was responsible for designing the solution, allocating work out to other developers and acting as primary liaison. Occasionally I had to decide how my time should be split either coding and fix issues quickly, spent time helping others, or communicating project status. 

•  Technically lead a team of 7 engineers to design, develop and deliver cloud-based broadcast systems for interactive data playout (including red button services) across multiple platforms (Freeview, FreeSat, Sky and Virgin Media).

•  Platform: Java 8, Spring Framework, Spring Boot, DynamoDB.
•  Deployment target: AWS, load-balanced autoscaling EC2 instances, SNS, SQS, S3.

Technical Lead

• Worked in the Connected Red Button team at the BBC – a very agile team that encourages practices such as pair programming, code reviews, TDD, and BDD. 

• The Connected Red Button is a service from the BBC that brings TV, online and BBC iPlayer together in the simplest way possible on the living room TV. It offers a world of additional programmes and features without having to leave the current programme.

• During the CRB Coexistence project, I was influential in the delivery of the feature across multiple platforms, from the initial design to helping the QA team. It was a great challenge due the time constraints and the involved changes of many different components. I participated in the development, design and planning of every single task related to this work. I created two MHEG tools that helped test and provided validation for broadcast changes, and it still used to verify persistent storage on broadcast devices. During rollouts, I improved the monitoring tools, and the system alerts to provide quicker / better feedback. 

• Key Technologies used: Java, Javascript, Mheg, OpenTV, Php, Ruby, Cucumber, Spring, Phyton, SQL, XSLT and various Broadcast technologies.

Senior Software Engineer

Pace

• Worked in Pace's COBALT software development team. COBALT is a service delivery platform hosted in the cloud, which comprises a TV management platform, multi-device application servers, and on-demand delivery systems within the operator headend;

• As a senior member of the team, my primary responsibilities included: 
 - Design, code, unit test and debug applications in various software languages; 
 - Integrate software with existing systems;
 - Review and repair legacy code;
 - Flag incomplete/ambiguous requirements as early as possible in development cycle;
 - Communicate any significant slippage in timelines;
 - Maintaining the systems once they are up and running;

• I also started to enhance the duties required for promotion to a Software Team Leader. It included:
 - Estimate, plan and execute software releases;
 - Task and track of software issues to team;
 - Interface with other groups: Quality, Sourcing;
 - Track metrics;
 - Report of project status to Software Manager;
 - Lead, mentor and inspire junior team members;
 - Motivate and encouragement of team under challenging targets;

• Key Technologies used: C/C++, Java, Web Applications, PostgreSQL, Relational Databases, XMPP.

Tecgraf / PUC-Rio

• Worked with the TecGraf’s Distributed Systems Engineering group. This group was formed for the purpose of investigating and developing new abstractions, architectures and middleware systems for the implementation of more flexible, robust and scalable distributed systems;

• Developed new features for a framework called ALOPE. It is responsible for providing relevant information to the supply chain of oil production in Brazil. The allocation is based on the deflation of the production platform’s tanks and the accumulation of daily oil by each refinery;

• Key Technologies used: Java, Swing, Distributed Systems, Client/Server architecture, and Relational Databases.

• Worked with the TecGraf’s Visualization and Reservoirs group. This group is responsible for developing and research products in the areas of Scientific Visualization and Photo-realistic Visualization, employing topologic representations of models, acceleration techniques for real-time visualization of complex models, rendering techniques, and user interaction skills;

• Led an R&D project named ROCHA. It was entirely designed and developed from scratch from July/2011 to July/2012. This project offered significant challenges, such as creating a tool that could improve the quality and speed of oil’s well productivity evaluation. ROCHA presented excellent results at finding lithofacies with different clustering algorithms, selecting the one with better values of cohesion and separation of inner clusters;

• Led multiple multi-touch solutions for Brazilian TV shows using various commercial displays. For each solution were developed new software using a base framework to deal with the different technologies. My primary responsibilities were to project and development, management of a small team, and deal with the client;

• Worked in the development of a football analysis system that converts key events from video to a 3D graphics model. Using computer vision algorithms and graphics, 3DReplay allows the creation of a 3D environment from a football match 2D image that is used to view controversial plays from different angles;

• Key Technologies used: C++, Lua, Iup, Swing, Client/Server Architecture Computer Graphics, and Computer Vision.

• Created a computer vision library for highway surveillance systems: able to track, classify and determine each vehicle’s speed on a motorway.  Key Technologies used: C++, Qt, Data Mining, and Computer Vision;

• Worked in the development of an interactive graphical post processor for unstructured tri-dimensional meshes, such as finite element models. The program is called Pos3D, and it is generic, efficient and independent of any particular analysis code. The software was developed for the visualization and analysis of solid and surface models. Its main functionalities include: mesh generation, attribute application, result visualization, and adaptive simulation for crack propagation in solids;

• Key Technologies used: C++, Lua, Iup, Computer Graphics.

Software Engineer
