Gangnam-Gu, Seoul, Korea

I was the leader of an autonomous team of 5 engineers (3 backend, 2 frontend) working on multiple applications involving chatbots. Our most significant project was a framework composed of a web platform to create chatbots along with various APIs to interact with them (from apps or IoT devices). It was used by PhD students at the University of Arizona to create an assistant for patients at the university hospital. Unlike typical chatbots that are just able to respond to user requests, our chatbots could be “proactive” and trigger interactions on their own (e.g. to check the patient health status, or remind them to take their medication).My role in the team was to gather business needs and technical vision from our CTO and to turn it into something concrete. I designed the technical architecture for each of our projects so that it could meet the availability and scalability standards. I was also taking part in the backend implementation that was involving various techniques such as natural language processing, machine learning and distributed computing. All the backend was built in Scala using a functional programming style that allowed us to be highly productive despite the small team size.Key technologies: Scala, Kafka, AWS (S3, DynamoDB, SQS), MongoDB, ZIO, Cats, Http4s, Akka

As the Head of Architecture for the Seoul office, I was leading a team of 3 Solutions Architects and responsible for the whole Poker system architecture. In direct contact with the Product Director, my main task was to design technical solutions that could meet the business needs in the short and long term, providing both high level architecture documentation and detailed requirements (e.g. API definition) for developers. I was defining non functional requirements as well as coding guidelines to ensure the various development teams work in a consistent way and reach appropriate quality standards. Finally, I was also assisting developers for troubleshooting challenging issues and improving the performance of the application.Our main projects included the following:- Architecture and design of a brand new Poker gaming server to replace the old legacy servers. This new system was particularly designed to be fast, easily scalable and fault tolerant. Key technologies: Scala, Java, Akka, Hazelcast, Atmosphere.- Design and support for a large technical debt reduction plan. The goal was to make the legacy system easier to maintain and more reliable, by reducing the complexity of the deployment, standardizing APIs into a well-documented and consistent format, automating builds and deployments, etc. Key technologies: C++, C#- Conversion of a C++ downloadable client to an HTML5 based client so that the same codebasecould be used on multiple devices (Mobile, Tablet, Desktop) instead of having two redundant codebases. Key technologies: QT, AngularJS, Atmosphere.

I was the first Solutions Architect to be hired in the Seoul office, therefore a big part of my work was initially to analyze, understand and document how the legacy system was working. Once this was done, I was able to propose improvements and to design technical solutions for our different projects, including the following:- Integration of a newly acquired gaming platform with the rest of the company gaming products. I had to analyze each product interfaces in order to define how the integration would work. Key technologies: C#, MS SQL Server.- Development of a Mobile and Tablet version of the Poker game client. This work required designing new “HTML5 friendly” APIs using REST and WebSocket protocols. Key technologies: LimeJS, Atmosphere.- Development of a new variant of Poker game. Key technologies: C#, C++, MS SQL Server

Auralog is a software publisher and the producer of the award winning TELL ME MORE language learning program, used by more than 7 million students in the world.I am entirely responsible for:- Architecture of the Data Access Layer for all developments concerning TELL ME MORE (C#, SQL)- Large scale database modeling (MySQL)- Study of feasibility and prototyping for various subjects (C#, e.g. a media conversion server, a distributed caching system, etc.)- Performance profiling and continuous improvement of code base and SQL queries- Technical supervision of two senior software developers

- Development of the Data Access and Business layers of TELL ME MORE (MySQL, C#)- Development of a speech recognition component (C++) usable in various environments (client side through an ActiveX or server-side through a web service)- Architecture and development of a web server capable of processing millions of speech recognitions every day (C#, C++)- Development of client-side prototypes for various kinds of activities (ASP.NET, JavaScript, Flash)
