Dedicated and organized Solution Architect and a Fullstack Developer with bachelor and master computer science education and 4 years of experience working in the IT industry building and maintaining projects ranging from microservices to large monolith solutions in the environments which demanded strong time and priority management. My mission is to make new and existing business processes more efficient by building IT solutions with high commercial value around them. In short, the scope of my work includes: - Team management - Interviewing candidates and onboarding new team members - Collecting and suggesting user stories/features (Conducting interviews with clients) - Formulating product requirements - Requirement breakdown and task estimation - Fullstack development of the tasks (database, backend, frontend) - Writing technical and solution documentation - Testing of the developed software (TDD, writing unit and integration tests) - Deployment - Software Maintenance (database patching, bugfixing,...) ------------------------------------------------------------------------------------------------------ PREVIOUS WORK: Until August last year, I worked in Copenhagen for an IT consultancy company as a software developer. This dynamic environment required good time management, constant adaptation to the clients’ needs, and learning about their business. It also required learning new technologies necessary to provide the requested services. During my tenure in the company, I worked on five different projects as a member of SCRUM teams that counted up to seven members. My roles on these projects included frontend, backend, and full-stack development. Sometimes these roles were client-facing so I communicated directly with the clients to understand their business processes, new functionality requests, and newly emerging issues. Finally, the experience of working in a consultancy has thought me to adapt to the existing codebases fast and integrate well within the new teams. One of the projects I worked on was Rejsekort portal, where the solution is built using C#, .NET, ASP.NET, Entity, MSSQL, Angular with Typescript, and usual frontend tools - JS, jQuery, CSS, HTML. On this project, I was acting in a full-stack role, working in an agile setup, developing both frontend and backend based on the functional requirements, doing database management (implementing tables, views, indices, stored procedures, etc.), as well as being responsible for Continuous Delivery of the system (through Azure DevOps). My other tasks included incident management and analysis, along with proposing the solutions to these occurred incidents. In the past half a year, I have been working on several projects utilizing .NET 6, Java (Spring Boot and Hibernate), SQL, Node.js, and React.js with Typescript. Two of these projects are a job ad portal and a laundry management system. These systems consist of client applications and REST API services designed following SOLID principles. Both of these projects and others are referenced in my CV and are available on Github ------------------------------------------------------------------------------------------------------
