David An

A full-stack developer skilled to build web applications with various technologies.

With 16 years of experience, I am quite adaptive to different architectures but my usual pattern is 

1. Frontend with JavaScript,
2. Backend with .Net / Node.js
3. DB: SQL Server / Mongo
4. Dockerize and push to AWS-managed services such as Fargate/EB
5. Security with OIDC/OAuth

I have seen things don't always happen as you planned and I learned how to relentlessly run an infinite loop of adapt-overcome-deliver-improve. 

If you find my skillsets helpful for your organization, let's have a conversation.
