Implemented a student grading system for an AI teaching platform utilizing React and Redux. Derived total score from redux state and sent it to backend asynchronously.

• Developed a 5G core simulator leveraging microservices architecture based on 3GPP technical specifications with Go for backend and OpenAPI for REST API generation; supported horizontal scaling to handle 150k requests per second, resulting in a $5 million B2B deal with a major internet service provider.

• Constructed a traffic modeling framework in Python to parse ISP customer data to generate simulations of real-world network traffic; utilized model to optimize hardware utilization, resulting in a 30% reduction in deployment costs.

• Onboarded and mentored three junior engineers in code quality, design, and concurrent programming; guided one to contribute to an open-source project, fostering professional growth and expanding team capabilities.

• Implemented a GTP-C feature in C++ to support network transitions from 5G to 4G and vice versa, resulting in 20% revenue growth from 5G solutions and improved operational efficiency by streamlining network management processes.

• Assumed ownership of Trex and SvTrgen, used for 90% of company's traffic simulation activities. Took charge of planning new features and managing bug fixes, resulting in an 80% reduction in new incoming bugs.

• Saved 256+ hours of annual testing effort by developing a Python client for a TCP traffic simulator and integrating it with an in-house test automation framework.
