SUMMARY
As a software developer with 5 years of experience in e-commerce, I have honed my skills in Node JS,
TypeScript, and Java, working on projects with microservice and serverless architecture for large-scale
software products. My extensive experience in creating APIs and product documentation using Scrum
methodology has equipped me with the expertise to deliver robust backend solutions. I am particularly
interested in continuing my career as a Backend Developer or FullStack Developer, where I can leverage my
skills and experience to contribute to innovative projects.
