Work Experiences
CallNet Korea. Seoul, S.Korea
Junior Software Engineer | 2022 – Present
- Developed and maintained PHP (Laravel) + React web applications integrated with the company's contact center solution in both Linux and Windows environments.
- Built customized APIs according to client’s requirements such as call control, agent status monitoring, and real-time dashboards for agents and supervisors.
- Modified and maintained contact center solution modules written in C and C++ according to client’s requirements.
What I did
- 1. Legacy Code Audit and Enhancement
- Remediated security vulnerabilities.
- Optimized data processing bottlenecks.
- 2. Modern Development Environment Proposal and System Design
- Transitioned from procedural legacy PHP to a Laravel + React based architecture.
- Established code conventions.
- 3. In-house Git Server Deployment

What I learned
- 1. Latest technology is not always the answer. Customers pay for solutions that meet their needs, not for the technology itself.
- 2. Technology is not the only solution. Non-technical approaches (such as communication and attitude) can also be effective ways to solve problems.
- 3. Code must be tested.
- 4. What is good or bad is context-dependent. While technical standards exist, the "best" code depends on the specific situation and constraints.
- 5. Being a "good collaborator" is more valuable than being an "egoistic artist" in a team.
