- 18:00 – 18:30 Getting together
- 18:30 – 19:20 Kafka Streams – a database inside out, Miron Brezai, Software Architect @ eSolutions
Kafka Streams is the easiest way to write scalable stream processing microservices. In this presentation, I will go over the architecture of Kafka Streams, will explain KStream and KTable – their differences and similarities and the local storage of Kafka Streams, how we can make joins between streams and tables and how to aggregate objects based on events grouped by id. Basically is about processing and joining infinite database tables.
- 19:20 – 20:00 Cassandra 4.0 – What to Expect, Aleks Volochnev, Developer Advocate @ Datastax
Apache Cassandra has been a driving force for applications that scale for over 10 years. This open-source database now powers 30% of the Fortune 100. Now is your chance to get an inside look, guided by the company that’s responsible for 85% of the code commits. You won’t want to miss this deep dive into the database that has become the power behind the moment — the force behind game-changing, scalable cloud applications.

- 19:00 – 19:30 Own your path | Roxana Raicu
- 19:30 – 19:45 Qualitative data analysis | Catalina Dumitru
Working across disciplines and cultures is complex, particularly in project teams. Building and maintaining trust between team members alleviates the challenges of project work by increasing perceptions of similarity, reducing information complexity, managing multiple reporting, and developing team reflexivity. By analyzing interview and observation data from several project teams in Germany and Singapore, I offer a description of trust practices that build and maintain trust in teams in different cultures.
- 19:45 – 20:15 Quality guidelines for mobile apps | Rafaela Voiculescu
Two of my passions are business and programming, two areas that I discovered distinctively: the former in university and the latter almost a decade later. The decision I took to pick up programming lead me to work for one of the most well-known tech companies, Facebook, as a Solutions Engineer a role that constantly challenges me and offers me countless opportunities to grow in both areas. In my current role I work closely with top gaming companies that integrate in-app advertising across the two mobile platforms: Android and iOS. On the business side some of my past roles took me on a deep dive into consulting, logistics, finance and sales. My superpower is receiving and acting on feedback.

BucharestFP invites you to talk about the contributions to the world of formal verification, using the open-source K framework. RSVP and let’s meet on March 10, starting at 18:45!
About the event
This talk will be a brief introduction to K by example and by comparison with Haskell. We’ll start by discussing the programming language IMP, with some demonstrations of programs in this language. Then we’ll show how to make an interpreter for this language in Haskell, including a parser and evaluation engine.
Finally, we’ll transition to a K interpreter for this language, and show how in addition to an interpreter, K gives a symbolic execution engine that can be used to do program verification. Any remaining time can be used to try things live and for further discussions about what verification is.
About the speaker
Everett Hildenbrandt is a Formal Modelling Engineer and Product Owner at Runtime Verification, Inc (a software quality assurance firm). He currently works mostly with KEVM, a K semantics of the Ethereum Virtual Machine (EVM) https://github.com/kframework/evm-semantics.

- 19:05 – 19:45: Kotlin, a language to rule DSLs by Tiberiu Tofan (ING Tech)
Kotlin, a language to rule DSLs – Kotlin is a great language for creating internal DSLs. Although it is statically typed, some of its features, such as type safe builders, extension functions, operator overloading, implicit receivers, etc. make the creation of internal DSLs a rewarding experience. We will explore some existing DSLs, and look under the hood to see how we can tailor the same principles to our needs.

Join us to learn how to create your own temperature monitoring sensors 🌡️ and to talk about Virtual Memory – the basics and advanced topics. RSVP here to save your front row spot on February 17, starting at 18:30!
About the event
We’ll take you through the challenges you’ll face when trying to deploy a large scale number of IoT sensors throughout a company’s working environment. From building, programming, and securing the devices, there are a lot of interesting details to work out for a successful long-term solution.
There are a few systems out there that do not use the benefits of the Virtual Memory, like some embedded systems which do not need isolation between applications, but for those that do use the Virtual Memory, the performance of the applications might be impacted by the overhead introduced by it. The second talk will tackle the basic concepts and a few advanced topics of the Virtual Memory.
About the speakers
Radu Andritoiu is a Software Engineer that’s been with Ixia for almost three years now. Radu’s work on multi-layered software applications for Ixia Network Packet Brokers has been remarkable.

Join Software Crafters for a meetup about the Inverse Conway Maneuver, a demo focused on REST API and service layered architecture. RSVP here to save your front row spot on February 5, starting at 18:45!
About the event
“Any organization that designs a system (defined more broadly here than just information systems) will inevitably produce a design whose structure is a copy of the organization’s communication structure” – Conway’s law (Melvin Conway,1968).
Eric S Raymond paraphrased the initial paper in The New Hacker’s Dictionary: “If you have four groups working on a compiler, you’ll get a 4-pass compiler.”
This observation has been confirmed by many subsequent observations and studies.
If you think about your own experiences chances are you’ve seen the effects of Conway’s law in the systems you worked with.
Conway’s Law counterpoint, known as the Inverse Conway Maneuver, involves re-engineering the structure of an organization based on a desired software design.
In this presentation there will be some examples of Inverse Conway Maneuver used in real life dealing with legacy code, splitting a monolith and increasing the ownership in software development teams.
In the second part of the event, it will a demo focused on REST API and service layered architecture.
The presentation covers
– Design decisions for scalability and constraints
– separation of different layers in an architecture
- 18:45-19:00 Welcome and short intro
