SRDC - Full-Stack Software Engineer/Architect (October 2008 - Present)

I worked for large-scale projects lasting 3-4 years with international, multi-disciplinary teams. As a full-stack engineer, I designed and developed distributed, scalable, (micro)service oriented applications and have become experienced in several backend and frontend technologies. Alongside full-stack development, I undertook team-lead and software architect roles, leading a team of engineers and design decisions related to high-level architecture. I also acted as a product owner communicating with customers/end users and bridging them with software engineers in my team. I designed product features; worked on planning, scoping and prioritization of sprints and issues. Below, I've listed the main projects that I worked for:

Toptal / Upwork - Full-Stack Software Engineer (December 2019 - Present)

As an exploratory extra-work activity to learn and keep myself up-to-date with contemporary technologies, I got several small-scale jobs on freelance platforms lasting 1-2 weeks. One of them was relatively larger, which lasted almost 2 years.

You can check out my complete portfolio in detail in Toptal and Upwork profiles.

Apache Software Foundation - Committer / Full-Stack Software Engineer (March 2011 - December 2012)

I'm a committer for Apache Stanbol. The main aim of Stanbol is to develop modular content enrichment services; using semantic, linguistic and lexical technologies, which could be used as external services or as embedded components by legacy content management systems. My role in Stanbol was to implement services for managing the produced semantic enhancements without losing semantic meaning and context awareness. In addition to storage functionalities based on different storage and indexing infrastructures including Apache Solr and Apache Jena, I implemented semantic search functionalities considering the relations between words/concepts coded in different lexical ontologies including WordNet or other domain-specific ontologies.

SRDC - Researcher (October 2014 - Present)

As a researcher I've involved in and worked on all phases of proposal preparation in the scope of European Commission's H2020 and Horizon Europe programs.
In manufacturing domain, I've investigated data virtualization methodologies for collaborative decision making across the product life-cycle: from inception to design, manufacturing, use, maintenance and after-use.
In eHealth domain, I've participated in research on the design of decision support system for patients with chronic cardio-respiratory diseases integrated with real-time telemonitoring system. The decision support system was supposed to prevent exacerbations via predictive and probabilistic modeling on prognosis of diseases.
Further in eHealth domain, I've involved in design of a system (i.e SALUS Project) aiming to utilization of electronical health records (EHR) aggregated in hospitals or similar clinical care organizations in drug post market safety studies. Together with my colleagues, we've designed methodologies for semantic and functional interoperability among various clinical information systems, content models and clinical terminologies.

A Framework for Design and Personalization of Digital, Just-In-Time, Adaptive Interventions

In my PhD studies, I've developed a preventive health framework for design and execution of just-in-time notifications tailored to individuals. The tailoring was realized by a beyond the state-of-the-art reinforcement learning algorithm learning personalized patterns in real-life settings by processing momentary and historical environmental/psychological/physiological data. The design framework provided preventive health researchers with the capability to define interventions targeting diverse diseases with a rich set of configuration options.

Enhancing Content Management Systems with Semantic Capabilities

The main aim of my graduate studies was to enhance legacy content management systems with features considering the semantics of managed content. Driven by this aim, I've built a CMS-pluggable system realizing 1) content retrieval from legacy content management systems, 2) enhancing content with domain-specific semantic annotations, 3) storing semantic annotations in dedicated indices, which are one-to-one compatible with the structure of domain-specific semantic annotations. The system described above was implemented in the scope of Apache Stanbol.
