To improve advisor efficiency, I extended the platform’s website with additional real-time customer acquisition insights. This gave advisors a clearer view of the client’s onboarding progress and helped resolve verification and data transmission issues faster.I also enhanced the data housekeeping algorithm to automatically clear stuck contracts. This reduced system bottlenecks, allowing advisors to focus on active contracts without being distracted by incomplete or outdated ones.For the on-premise and cloud integration, I developed synchronization procedures that enabled secure data exchange via a predefined channel, ensuring smooth communication while maintaining data security compliance.Finally, I implemented a legacy data importer to support customers still using the old application format. This ensured their data could be processed without disrupting the updated platform's functionality. I developed new features within the existing software application to enhance functionality without disrupting the established workflow. This included seamless integration of the new requirements into the existing Spring-Batch-Flow. To streamline communication with financial institutions, I automated the data exchange processes. This automation ensured that data transfers occurred consistently and efficiently, reducing manual intervention and minimizing the risk of errors. For better user experience, I extended the error feedback mechanism through a REST API call. This provided users with human-readable error logs directly in the frontend system, helping them quickly understand when an issue occurred and improving their ability to resolve problems efficiently. For syncing data between the on-premise and cloud applications, an export-import solution using an SFTP server was implemented. The on-premise application required data from the cloud, so a scheduled procedure was developed. This process involved exporting the cloud application's data through database dumps, encrypting the data, securely transferring it to the SFTP server, and detecting changes before importing the data into the on-premise system.

The innovative communication solution, corpuls.mission CONFERENCE, addresses the challenges of efficient and rapid communication in emergency situations by enabling mission and patient-specific exchange via chat, audio, and video calls, tailored specifically for first responders in the field. This revolutionary platform allows for live consultations with doctors or specialists, the sending of images, videos, and voice messages, and contacting tactical units instead of individuals. Available for Web, iOS, and Android, CONFERENCE ensures that first responders can directly request specialists such as cardiologists without needing to dial individual numbers. This solution enables optimal, real-time medical consultations and significantly improves the efficiency and effectiveness of rescue operations. Our team is responsible for the development of the web app. For the web interface we rely on the Angular framework, the programming itself is done with TypeScript. The backend is built on a Spring boot application with Java and provides REST interfaces, as well as web sockets for the various clients. As for the database, we use a MongoDB. Since the application is used worldwide, we implemented an internationalized hybrid that offers each client a high degree of customizability of the terminologies.

Our team developed a high-performance cache that is designed to manage hotel room data based on external data and internal business factors. This cache provides a vast range of listings that can be refined by options such as occupancy and customer markets, allowing customers to swiftly locate an appropriate hotel room within their desired area. We developed a series of microservices with Spring Boot to operate this cache and deploy them to an AWS Kubernetes cluster. We also established Lambda functions to take in SQS and SNS streams from the enterprise and route them to the core Kafka message bus for further processing. The final step was to put the data into a DynamoDB so that it could be available for search queries.

The existing web-based and absent tariff calculators need to be restructured and executed in agreement with the current inner procedures and with optimal performance. We developed several apps utilizing Angular. I worked on behalf of four teams and incorporated a variety of Angular components for diverse tariff calculators, utilizing our in-house produced UI components. Not only did we upgrade the look and feel of the frontend - we also introduced tools such as A/B testing to enhance customer contentment and improved automated error logging to respond even quicker to technical issues in production.

To significantly decrease the amount of time it takes to process an order, a direct link must be established. An interface should be created to facilitate this. During the initial conversations, the details for the new interfaces were already outlined and it was determined that REST ought to be used for transferring information and reporting statuses. Since the service was unable to offer the interfaces yet, a microservice was put in place to imitate the identified interfaces and provisionally support the development and testing procedures.

In order to make the submission, review and approval of grant applications more efficient, they should be processed through a modern web interface that is accessible to both applicants and public service processors. Using RPA to partially automate the approval process and manage access, a multi-step web forms platform was developed to allow access for specific individuals based on the step in the process.

I supported 2 teams, in which I implemented an admin dashboard for graphical analysis of internal data and assisted on the frontend in processing user stories. In addition, I held a 2-day Angular workshop for a group of ~10 Java backend developers. The workshop was divided into theoretical and practical phases so that the participants could immediately apply and expand their knowledge. An introduction to Angular, Angular Router, Observables, Angular Forms (template-driven and reactive), Angular Architecture (Components, Inputs and Outputs, ContentChildren and ViewChildren), and Angular Material were covered.

A crucial element of a regulation is the visual assessment of extensive data. This should be depicted through charts and tables. I created a GWT extension to figure out and show the necessary figures. The assignment involved both client-side and server-side components.

An hybrid iOS application was developed to digitize the review procedure. Apple iPads that were not connected to mobile Internet were used as work devices. To limit data synchronization to the company's own WIFI, employees loaded questionnaires and routes onto their iPads prior to starting work. Employees completed their routes, returned to the company's WIFI, filled out forms, and uploaded the resulting data to the server. We developed an Angular application that became installable on iOS devices using Ionic Cordova. We used a local SQLite database with a partial database image to provide offline functionality. It also contained usernames and MD5-encrypted passwords for local authentication.

We conceptualized and developed an audit report feature, allowing the client to generate an audit report for the annual audit. Together with the client, we created a report structure and created a function that collects the required information when entering start and end times, and transfers it to the proposed PDF export layout in summarised form.

The sports club wants to improve its members' ability to organise, communicate, and track one another using the mobile app. A chat module should be included in this effort. A custom chat element was developed for the mobile application that includes features such as 1-to-1 chat, status markers to indicate status (sent, arrived, read), group chats, automatic group participation based on hierarchical group membership (club chat, team chat), and interfaces to other modules.

The Service staff would briefly hold a previously issued card up to an Android device and the customer pays at the exit, rather than at the checkout. This saves the service employee time. A combination of Spring Boot and an Android app was implemented. Near Field Communication (NFC) cards were chosen for the card system. The purpose was to make sure the system can continue to run properly even when the connection is lost by providing a synchronized storage of the data on the card and the server's database.
