About

Hello, I'm Jacob Wilson, a Senior Software Engineer and Full Stack Developer with over 11 years of experience in crafting innovative software solutions. I hold a Bachelor's degree in Computer Science from City University of Hong Kong and have a diverse background in both frontend and backend development.

My expertise lies in modern JavaScript frameworks such as React, Angular, and Vue.js, where I have successfully led the development of scalable applications and optimized performance for various projects. I am also proficient in C# (.NET), and Java, bringing a versatile skillset to tackle diverse software engineering challenges. I have extensive experience with TypeScript, Next.js, and GraphQL, which I've used to build high-performance web applications. I'm also proficient in backend technologies like Express.js, NestJS, and Go, as well as database systems such as PostgreSQL and DynamoDB.

Throughout my career, I have taken on leadership roles, mentoring junior developers while ensuring high coding standards through thorough code reviews. My experience includes designing secure authentication flows using AWS Cognito, integrating payment systems like Stripe, and implementing CI/CD pipelines (Continuous Integration/Continuous Deployment) to enhance team productivity and streamline deployment processes.

I have a strong background in cloud technologies, particularly AWS (Amazon Web Services) services such as Amplify, S3 (Simple Storage Service), AppSync, and Lambda. I've implemented GenAI chatbots using Amazon Bedrock and integrated video streaming functionality with Amazon IVS (Interactive Video Service) player. My experience also extends to performance optimization and monitoring using tools like DataDog and Sentry.

I thrive in collaborative environments and have a proven track record of delivering projects on time while maintaining quality. I am passionate about solving complex challenges through creative problem-solving and leveraging cutting-edge technologies to drive innovation.
