Inspired Gaming is a gambling software development company. One of their most important clients is Gala Casinos (leading casino chain in UK). Working in this company has increased my knowledges of multithreaded environments with high concurrency and low latency. Responsibilities: - System design and development (Spring) - Design and optimization in SQLServer. - Multithreading/Concurrent: Highly concurrent systems, the amount of gamblers that are playing concurrently can be really high (all casinos are connected to the same server). - Asynchronous messaging was implemented with JMS (ActiveMQ) Show less

Markit is a leading, global financial information services company with over 2,000 employees. Its client base includes the most significant institutional participants in the financial marketplace. I am currently working in the Valuations Manager division developing a web-based platform which provides buy-side clients with multi-bank counterparty position and valuations data in a consistent format, along with optional independent valuations. This is a highly transactional system where millions of valuations are processed everyday. Some of the most cutting edge technologies are used in this system such as Terracotta EhCache, Spring, JTA… System features - System design and development (Spring) - Oracle database design and optimization (indices, partitions, PL-SQL…). - Highly transactional system, a bunch of batches are executed every day that insert and modify millions of row, JTA was used to manage the transactions. - EhCache is used for the data caching. A Terracotta EhCache cluster (3 nodes) is configured to speed up all the processes of the system. - Spring JDBC is used for the database access. - The system is deployed in Tomcat 5.5 server that is running in a cluster composed by 2 nodes. - GIT was chosen for the control version system.

Deimos Space specialises in building high complex aerospace software. The company is mainly involved in the development of Galileo (European GPS). One of the most important sections within the company is the transport section where is developed cutting edge software for the railway industry. In my last role I was working as a Java developer in the aforementioned section and I was involved in the full software lifecycle including requirements gathering, design, implementation, creating documentation, consulting, testing, system deployment and support. The complexity of the systems in which I was involved has given to me important insights into multithreading environments. I have also actively participated in the design and implementation of highly distributed systems (with up to 1000 nodes in Barcelona), thus I am fully qualified as a SOA developer. Main responsibilities: - Spring based system design and development. - Database design and development: For persistent storage we often use relational databases (Oracle, MySQL…) and Hibernate for object-relational mapping. - Highly distributed system design and development. - Multithreading/Concurrent design. The system receives real time traffic information and it is processed with a low latency. - JMS (ActiveMQ configured with Spring) was used to send and receive asynchronous messages by the system. All the different events (train traffic events, device events…) are propagated through the system using JMS. Show less
