Full-Stack Developer. Implemented multiple components for Storyteller and Regulatory Compliance Management (RCM) systems, using Typescript, JavaScript, AngularJS/Angular on client side, C# on backend and SQL Server DB. Worked in Agile team, using Scram and Kanban methodologies.• Designed algorithms and developed the vital components for Storyteller Process Editor, using Typescript and mxGraph SVG based graphic library. Excluded Lodash because of the performance considerations, i.e. used vanilla “for” loops instead of Lodash loops (like _. each, _.filter, _.map and so on). o Created multiple diagram components (shapes and connectors). o Designed optimal layout algorithm for the diagram presentation. Algorithm is based on the creating of a virtual grid and locating the shapes in it’s vertices. o Developed RxJS-based messaging mechanism to deliver messages from/to Angular based application. o Created custom Label component that resolves performance issues of the mxGraph Label.• Designed and developed HTML-based TextView component that represents Process Diagram in a tree-like text view. Created classes per shape type extending base Shape class with the render abstract method, which contains rendering logic of the corresponding shape. Also excluded Lodash and Angular because of the performance considerations.• Designed and developed the base code and the most complicated components of the Unified Modeling Editor (UME), which is the Visio like diagram editor providing user with several shape libraries, including a simple shape library and BPMN shapes library. This work was done using GoJS canvas-based diagraming library. Implemented algorithms for finding of possible collisions of the connectors (right angled lines) and different geometric shapes.• Designed textual search algorithms that compare artifacts sequences and calculating matches within the search confidence criteria to extract redundancies among large datasets, using bidirectional dictionaries.
