Tech-lead - development of data-ingestion and processing suite ReportingStackLeading a team of developers and application programmers in a joint effort to blend industry leading components (Apache Camel, ActiveMQ Artemis, FastAPI, MongoDatabase, PostgreSQL) into a common software platform to address specific data-driven needs. Product is built using Gradle tool, all components tied together in a micro-services driven pattern. Responsible for developing a comprehensive test-suite to support CI/CD pipeline.Programmer - ReportingStackRegular contributor to code - developing procedures and classes in Java/Groovy, programming integration routes in Apache Camel (DSL, beans, processors), developing frontend in Vue.js (Quasar framework), QA scripts in Python, Gradle tasks generation scripts. Dockerfiles, docker-compose configuration. Partially responsible for deployment in production.Project manager - development of CLARIN-DSpace Responsible for managing a team of developers (both on-site and remote) working on a fork of Lyrasis' DSpace project for Charles University of Prague and University of Oxford. Primary objective of the project was codebase upgrade (to the latest version) and migration of features and functionality from older versions.Implemented projects:1. Project Controlling integrated with Alresco DMS - Single-page application (in Vue.js/Quasar) allowing user entry of project calculations (MS Excel) with simplified workflow features. REST API based integration with DMS, data stored in MongoDatabase and Postgres. Aggregated data presented in ApexCharts.2.

Primary objective assigned by ŽSK was to extract (selected partition of) accounting data from its 108 subsidiary organizations and store it in a centralized data-repository and bring up-to-date search and analytical capabilities that would allow further vizualization and specialized post-processing. Each organization's data was stored in a separate legacy system, with no data-extraction functionality. We did it the open-source way. What was delivered? A custom-built application suite featuring these components:- Apache Camel framework for orchestration of files ingestion,- FastAPI for selected components used in processing pipeline,- ElasticSearch single-node cluster to allow fluent search and aggregation,- Moqui.ERP as robust backend foundation,- modern UI solution based on Vue.JS (on Quasar) - a full fledged Progressive Web Application to accommodate requirements,- MetaBase BI solution,- Postgres database for database storage,- RPA plugin (OpenRPA) was introduced and presented as a mean of a regular tool that could be used to extract data on a regular basis.Solution was based on dataquest's ReportingStack foundation.
