        GraalVM – the newest JVM extension generated a lot of buzz in the industry,  already earning the trust of such industry giants as Twitter. The promises GraalVM gives definitely sound good: a better performance, as well as seamless interoperability between multiple languages, all running on the JVM. Should we be interested in it too? In this talk Pijus will explain, what exactly is GraalVM and what hides behind the scene and Milda will demonstrate GraalVM polyglotism, exploring weather we can actually create seamless applications, selecting the best programming language for our tasks, without the overhead.

      • Arturs Drozdovs from Intrum Global Technologies will give a talk The one and only way of designing Java applications”.
        There is no “one and only” way; each team has to choose the most suitable approach for their situation and project. What is common throughout all the teams is the need to make choices. In this talk we will look at the choices we’ve faced in our team, what options did we consider and what conclusions did we come to.

      • Olegs Anastasyevs from will give a talk “Resilience in Distributed Systems”. is the most popular social network in Russia and top 20 website in the world. And it is one of the largest, complex and highly loaded distributed system: 1000s of servers participate in user requests processing in real time. Each of these servers has only small part of data locally and implements only a fraction of processing logic. Social network can hardly be built using shared nothing architecture, so there is a lot of shared state, network communications happens between our servers, different in kind and widely varying in volume.
        In distributed system of such scale we can hardly find a single second free of some failure, glitch or lag. How to build a continuously failing system, which works correct nevertheless? What are full and partial failures and how to address them?
        What do idempotence and speculation mean? What should be implemented upfront to workaround outage of the large subsystem or “main” database? How to manage pre-production tests and release delivery?
        There are many hard questions in distributed systems development. In this talk I’m trying to give answers on them.

Agenda for FinTech focused 70th

    • Erik Kaju from TransferWise will give a talk “How to build a payment card product”.
      For a long time payment cards used to be the domain of banks. In the last decade, the paradigm has shifted – we see more and more regular enterprises issuing their own cards, be it telcos, grocery store chains, various fintech startups etc.
      But what does it take to build a payment card from scratch? How do cards work? What is the anatomy of card transactions?
      This is a talk focusing on technical and product aspects of the card issuance, based on true story.

      Erik is leading the payment card product engineering at TransferWise. Loves all aspects of product engineering – from validating the market fit, establishing partnerships and negotiating deals, to designing technical architecture, building the team and bringing hyper-growth products to live.

    • Dmitry Buzdin from a-heads consulting will give a talk “How payment cards really work”.
      This talk is an introduction about technical aspects of how payment cards function, what technical protocols are involved and what are implementation complexities in a typical payments project. You will learn about concepts like 3DSecure, Authorisation and Clearing, Tokenization and know about novelties in the payment world, which will affect consumers in the nearest future.

    • Jake Sebastian-Jones from Nordigen will give a talk “Data is not enough, you need information”.
      Having a lot of raw data by itself is meaningless – you need to extract information from the data. Banks and other financial institutions have a lot of data but surprisingly little information. This talk will explain how Nordigen uses transaction data to provide multiple tiers of information to financial service providers.
