I'm working as a freelancer with this company at my spare time. I'm developing local jobs with this company and mainly worked on 2 different AWS serverless webapps(react, node, python) stacks. Just doing a preparation on this company for a new opportunity.

I developed the research and advisory firm that focuses on high impact research. We should have to support our customers to make better decisions on special industries such like business, financial, etc. I developed the serverless frontend webapp by using react and AWS services. For the isolated component development we used storybook with 2 frontend developers and AWS lambda functions as a microservices. We completely developed our webapp as a AWS serverless webapp by using various its services such like s3, dynamodb, cognito, api gateway, ses, sns, ... etc. I studied so many new modern technologies to skill up my selves on this company and really affected my developer career. We've got 23 members of engineering team which includes QA, DevOps, FullStack, Frontend, UI/UX designers. I like the team!

I developed the healthcare platform on this company for supporting customers to take greater control of their financial health and personal wellness. I worked as a senior software engineer who both handles the frontend(react) and backend(node), also cloud platform(AWS) side. Our tech stack was react/node/typescript/postgresql. Also we used various AWS services to storing datas and email, notification, hosting, cloudfront, etc. I mainly focused on backendside on this company and we used react/redux/redux-store, material-ui, react-hooks to develop our frontend webapp. In this company as a senior software engineer, I should have to mentor and review my 2 junior developers which ones working on frontend and backend. It was great experience for me in my professional career.

I worked with a freelancer contract on this company. I built e-commerce platform which sells T-shirts mainly, so built the webapp with angular/node/typescript/mongodb stacks. The client was very handsome and fully mannered, so it was greatful work with him. After 1 year later we started migration from angular to react and I handled both frontend and backend. While integrating the backend, I used ORM library and swagger-ui to visualize the RestAPIs. I worked with 2 developers who came from UK and Canada, so professional git work is most important for us to collborate remotly. Great experience besides of my regular employment work.

I developed platform(Pangeans) to support colleague students for freelance work. Our engineering team involves 12 members of software engineers. My major tech stack was angular/node/typescript/mongodb. It was really exciting platform as my first career. I worked as a fullstack developer and I mainly focused on the frontendside on this company.
