At T Ninjas, I've been working as a Full Stack Developer, focusing on modernizing legacy applications and enhancing user experiences. One of my key projects involved migrating an Angular application to a high-performance React single-page application. This migration significantly improved initial load times and overall responsiveness. I implemented asynchronous programming techniques and responsive web design principles to ensure smooth performance across various browsers.In addition to the frontend work, I revamped our RESTful APIs to GraphQL, which substantially reduced data over-fetching and streamlined front-end integration. This involved utilizing Python for third-party API interactions and implementing Express.js for the GraphQL server. To complement these technical improvements, I designed a user-centric interface using Figma, focusing on enhancing the user experience and improving conversion rates. Throughout the development process, I emphasized code reusability through custom hooks and conducted extensive unit testing with Jest.

As a developer for AWS Athena's serverless interactive query system, I created customer-centric features based on business requirements. I utilized ReactJs and TypeScript to develop new features for the AWS Athena console. To ensure timely feature launches and customer usage tracking, I implemented code using Amazon's component library (CloudScape) and feature flagging logic. I conducted Spike analyses to identify potential issues and proposed solutions. Collaborating with PMs, I defined business/technical requirements and worked with UX designers (FIGMA) to discuss user flows. I customized UI components in various modes and implemented keyboard and mouse functionality. I communicated with stakeholders, including security engineers, to ensure smooth application security reviews and penetration testing. I led bug bashes and coordinated with leadership to drive feature launches. I tested and debugged programs, troubleshooting problems of limited scope following standard practices and procedures. Working across teams and services, I provided an integrative experience for customers that improved performance, increased capabilities, and reduced cost. I corresponded directly with customers to resolve blocking issues and pain points. I also worked with tech writers on public/private documentation, managed CI/CD pipelines, and integrated them with GitHub for seamless code deployment, version control, and consistency across code branches.

I developed a cross-platform mobile application using React Native for TNinjas. This application facilitated seamless feedback submission on both iOS and Android devices, leading to a 20% increase in user engagement. I implemented secure authentication and authorization features using AsyncStorage and React Navigation to safeguard user data. Additionally, I integrated interactive data visualization components with libraries like Victory Native. These visualizations provided real-time insights into feedback trends, empowering administrators with improved decision-making capabilities. Furthermore, I spearheaded testing efforts, achieving a 90% code coverage rate with Jest and React Native Testing Library. This comprehensive testing strategy ensured robust functionality across platforms and resulted in a 30% reduction in post-release bug fixes.

During my time at ITC, I developed and maintained responsive web design (RWD) compliant web pages for internal stakeholders. I leveraged both Angular and React frameworks, ensuring consistent cross-browser compatibility through regular library updates and thorough code testing. Additionally, I demonstrated my ability to contribute to back-end development using Python and SQL queries.My focus on efficiency led me to develop a Selenium/Java that streamlined workflows within the CRM. This automation reduced manual data entry time by 10%, freeing up developers to tackle more complex tasks. This project demonstrates my initiative and ability to solve problems with technology.
