Profile: https://flows.cv/andrewk1

I am a Software Engineer with 14 years of experience in designing and developing full-stack SaaS applications. In my last role, I led a team developing a novel feature using Node.js in Typescript, deployed on AWS using Lambda. Over my career, I’ve taken a leadership role in planning, creating best practices, and writing technical documentation. I have worked in many areas; front-end applications using Angular and React, back-end APIs using PHP (Laravel) and Node.js (Lambda and NestJS), databases (RDS, CockroachDB, MySQL), and DevOps using AWS services like CodePipeline/Build/Deploy and CDK. I take pride in my strong communications skills and look forward to mentoring newer engineers.
