We are developing a financial platform for originating and trading digital assets. Our microservices are written in Spring Boot and we are using an enterprise blockchain as a base. Our aim is to add significantly more transparency and automation to digital asset creation.

Lead software developer

We were developing a mobile app and a web platform for automatically making virtual tours for real estate with your mobile and sharing them online. We were using augmented reality to guide the user and detecting photo positioning. We also did sofisticated image processing for tour stitching and 3D scanning.

Co-founder and software developer

We were developing compiler technology for dynamic analysis of C/C++ software. One tool was detecting bugs like data races and buffer overflows. The second tool was providing guidelines about how to parallelize legacy C/C++ software and what would be the speedup.

Software developer

I developed embedded software for network traffic generators.

Software developer intern

I developed embedded software for Nortel (now Avaya) network routers and switches.

I have been using Java on its own for more than 8 years now. In the last years I have worked extensively with Spring Boot to develop microservices. I have developed a couple of Android apps (one of which used to have tens of thousands of daily users). My less common Java related endeavours were Scala, Play web framework, Lagom microservices framework, Akka.

For more than a year now I have been a full stack developer, Java on backend and JS with React on frontend. I am pleasantly surprized how powerful and clean can React with ES6 or Typescript be, and I think much of that is because of the strong functional programming influence on the two technologies. I continuously strive for high quality in my code, by using extensive testing, strong type annotations, and well thought code design.

I have had a passion for functional programming since first trying Scheme in university. After graduation I wrote production code for three years in Ocaml, and later for two years with Elm and Scala. I have also been coding in Haskell for side projects.

At my current job, I have been developing microservices with Kotlin and Spring.

I have gained significant experience by writing Ethereum smart contracts for financial instruments. I also understand well how Bitcoin works. I have created a workshop to teach beginners how to write smart contracts and interact with Ethereum, which has been a big success.

I worked with C/C++ for different types of projects: I contributed to a major performance optimization for Blink (the web engine behind Chrome brower); I developed compiler technology with LLVM for dynamic analysis; I wrote software for network switches and network traffic generators; I did image processing for virtual tours with OpenCV; I wrote an AI chess player; I built a few robots.

I have a good foundation for algorithms. For my performance optimization tasks, I am used to do profiling, detect hotspots, and design new data structures and algorithms that make my memory, CPU, or IO bound application faster. I am familiar with doing computational complexity analysis using the O-notation. I have also worked for three years with parallelization: both using multi-threading with shared memory (OpenMP, Posix threads) and message based (MPI, Kafka, Hadoop).
