Development of a pivotal feature known as Email Analyzer—a comprehensive pipeline designed to analyze user emails and integrate the extracted data into our system. Which greatly impressed clients and increased client adoption. Leveraged AWS services and LLMs like GPT and Claude to optimize the efficiency and accuracy of the process. Implemented internationalization (i18n) for the software, enabling seamless adaptation to diverse linguistic and cultural preferences.

During my tenure at Atypon, I honed a myriad of technical skills, diving deep into Java programming - both intermediate and advanced. My proficiency encompassed Lambda functions, streams, JavaFX, multithreading, thread cooperation, and network programming, along with mastering OOP principles.

Specifically, I delved into:

Web App Development: Gained expertise in web app creation using Spring and explored the end-to-end development process from database communication with JDBC and MySQL to frontend development with React.

Linux & DevOps: Acquainted myself with Linux, shell scripting, and a DevOps toolkit, including CI/CD practices and Docker.

Java Best Practices: Imbibed the essentials of clean coding in Java, leveraging established design patterns for scalable and maintainable software.

Projects:

StudentGrading System: Implemented a 3-phase project:

Phase 1: Developed a socket server-client with a custom protocol, integrating JDBC for MySQL communication. Phase 2: Enhanced design using Java Servlets, JSP, and the HTTP protocol. Phase 3: Further refined the system by integrating a Spring REST API with a SPA React frontend. DockerVideoStreaming: Orchestrated a microservices-based architecture across six Docker containers. Key services included:

Auth Service: A Spring REST API storing users in a PostgresDB container. FileSystem Service: Utilized Express and TypeScript to manage files within a container's file system. UploadVideo & Stream Services: Enabled video uploading via a Spring MVC frontend and streaming using React and Express. Old Maid Game: Leveraged advanced multithreading to bring the classic game to life.

Uno Game Engine: Embarked on a design-centric project, applying advanced design patterns and SOLID principles to craft an extensible Uno game engine.

Streamlined the technical team's CI/CD pipeline, transitioning the version control system from TFVC to Git with GitHub platform and GitHub Actions. This improved collaboration, development, and deployment speed by 50% through effective leadership and resource provision. The technical team included 15 members. Implemented a survey system within the web chat widget using React, Redux, .NET, and C#, which provided valuable customer satisfaction data. This initiative boosted feedback, enabling us to respond to feedback faster. Designed a settings page for customizing web bot chat widgets, reducing development costs and customer wait times. Optimized the Dashboard page load times from 10 seconds to 4 seconds by optimizing the backend and redesigning the front end, utilizing lazy imports of Javascript scripts, and reorganizing the scripts for essential initial load, enhancing user experience significantly. Enabled data processing for clients by introducing Excel and PDF exports in the front end using Javascript and jQuery. This provided clients with more flexibility in data management.
