Full-Stack Developer

My goal in life is to use my skills in technology to make as much of a positive impact as I can. I've spent over 10+ years honing my skills in web development, and along the way have embraced many core tenets of computer science. Code reusability, optimization, and documentation are some of my specialties. For the past 5 years I have mostly worked with Javascript, React, Angular, Vue, Node, Python, GraphQL and associated libraries and technologies. I take pride in building websites and web applications that are responsive, accessible, and have a great user experience. My current development stack: βœ… Front-end – React.js, Redux, Next.js, Gatsby.js, GraphQL, Storybook – React Native – Angular 2+, NgRx, Angular Material – Vue, Vuex, Vuetify – Data visualization (D3.js, Chart.js) – Javascript, TypeScript, ECMAScript 6+ – Bootstrap, Less/Sass, SCSS, Styled Component – Material UI, Ant Design, Semantic UI – API integration (Stripe, Google Maps, Twilio, WebRTC, Socket.IO) βœ… Back-end – Node.js, Express.js – Python, Django, Flask – C#, ASP.NET MVC – PostgreSQL, MySQL, MongoDB βœ… Others – AWS Cognito, Lambda, Amplify, DynamoDB, S3, EC2 – Firebase, Firestore – DevOps, CI/CD, Docker, Kubernetes – Git, Github, Gitlab, Bitbucket – Jira, Trello, Monday, Redmine I have successfully completed many projects using the above skills, as well as with many other languages and tools. I love being a creator and problem solver and I especially love learning new ways to implement these both into programming and into every area of my life.
