• Designed and shipped GraphQL- and NestJS-based services that deliver faster, more flexible data flows, while reusable schemas, resolvers, and types accelerated feature delivery and simplified maintenance.
• Maintained and scaled an integration hub that connects with 50+ e-commerce marketplaces using Node.js, Express.js, NestJS, and SQL—optimizing performance, hardening reliability, and tightening error observability across connectors.
• Built custom integrations for marketplaces such as Temu and Amazon SellerFlex, implementing synchronized inventory and order pipelines that prevent overselling through rigorous cross-stock management.

• Led a team of 4 developers, overseeing the planning, execution, and delivery of key features, while maintaining high code quality and ensuring effective collaboration and communication within the team.
• Developed a platform that collects telemetry data from racing games such as Assetto Corsa, iRacing, and Assetto Corsa Competizione to help users improve their racing statistics. The system analyzes when to brake, accelerate, and how to control the steering wheel, allowing users to compare their performance with other racers on the platform.
• Constructed an End-to-End backend system with Node.js, Express.js, MongoDB, Nginx, AWS S3, and hosted on AWS EC2.
• Successfully handled over 2,000 users and saved more than 10000 laps, demonstrating the platform's scalability and reliability.

• Developed an e-commerce site using React.js and Node.js, which led to a noticeable increase in online sales. This project involved creating a user-friendly interface and ensuring seamless backend operations.
• Integrated the ThreeJS library to build a 3D design module for cardboard bags. This feature allowed users to easily customize various aspects of the bags, such as dimensions, text, texture, and frames, enhancing the overall user experience.
• Led the conversion process of four existing web applications to iOS and Android platforms using React Native and Expo. This initiative significantly broadened the user base and improved accessibility across multiple devices.
• Developed internal services for sending and receiving emails and SMS, as well as for storing, cropping, and adjusting the quality of images on a local server. These services streamlined communication and media management processes within the organization.

I focus on advanced web technologies, user experience, front-end and back-end development.
