Über mich

I hold an MSc degree in Computer Science from the University of Edinburgh and I have 13+ years of professional experience developing mostly Java applications. I have multiple years of experience leading Java software projects starting from proof of concept to bringing them live including financial software applications and big data projects. I have integrated multiple APIs using REST, FIX, XML, etc.

Throughout my career I was responsible for the project planning, estimation and implementation, stakeholder identification and management, risk and opportunity assessment for multiple projects. I've mentored junior developers and performed code and design reviews.

I have strong experience with relational databases (Postgres, OracleDB, MySQL) and deep knowledge of NoSQL technologies such as Elasticsearch, MongoDB, AWS DynamoDB, Redis.

Throughout a large part of my professional career I gained experience also as a DevOps engineer having used and set up tools such as AWS (S3, EC2, DynamoDB, RDS), Kubernetes, Docker, Jenkins, Maven. 

In terms of programming languages my primary language is Java (incl. SpringBoot, Hibernate). I have also mobile app development interest and have experience developing Flutter apps.
