✅ Contributed to the development of Bayer's Climate FieldView application, a digital platform that provides farmers with valuable insights and data-driven tools to optimize their farming operations. My role involved enhancing the application's functionality and user experience with technologies such as NodeJS, React, and the many AWS services. ✅ Played a pivotal role in creating and refining Bayer Digital Farming's APIs. These APIs serve as the backbone of Bayer's digital agriculture initiatives, enabling seamless integration of data and services across various farming applications and platforms. Through my contributions, I helped streamline and enhance the functionality of these APIs with event driven architectures and domain driven design, ensuring optimal performance and reliability for users in the agricultural sector.✅ Spearheaded the development of an application designed to streamline the onboarding process for partners into Bayer's robust API ecosystem. This application, built with Apollo, Typescript, NodeJS, DynamoDB, React, and utility AWS lambdas, serves as a pivotal gateway, facilitating integration and collaboration between Bayer and its partners. ✅ Took the lead in implementing automated alert systems to monitor API consumption for onboarded partners within Bayer's ecosystem. These alert systems, running on Cron jobs, and SNS, alongside AWS lambda, were designed to proactively notify both partners and internal stakeholders of any deviations from expected API usage patterns.✅ Played a pivotal role in developing orchestration layers to seamlessly connect public-facing APIs with internal systems. These layers built with Express, NodeJS, containerized with ECR/ECS, and deployed with Gitlab pipelines served as the backbone of our architecture, ensuring smooth communication and data flow between external partners and our internal APIs. By implementing robust orchestration mechanisms, we optimized performance and facilitated efficient data exchange.

✅ Assumed the leadership role in a team of software developers. Through effective guidance and collaboration, I fostered a culture of innovation and excellence in delivering solutions for HighTower's clients.✅ Developed a dynamic static website generator with AWS Lambda, Node.js, React and DocumentDB. By harnessing the power of serverless computing, I engineered a scalable and efficient solution that seamlessly combines the flexibility of React with the speed and cost-effectiveness of AWS Lambda. This approach enabled rapid website generation, enhanced performance, and simplified deployment processes, empowering marketing teams to create and deploy static websites with speed and ease.✅ Created a robust blogging application, harnessing the capabilities of AWS Lambda APIs, AWS DocumentDB, and React. By integrating serverless computing with a scalable NoSQL database, I crafted a powerful platform for content creation and management. This application not only provides users with a seamless blogging experience but also ensures scalability, reliability, and performance through AWS's robust infrastructure.✅ Developed a comprehensive file manager application, utilizing the capabilities of AWS Lambda and AWS S3. By taking advantage of the serverless architecture of AWS Lambda and the robust storage capabilities of AWS S3 we engineered a versatile solution for managing various file types including PDFs, images, and more. This application offers users a seamless experience for uploading, organizing, and accessing their files securely in the cloud. Through careful implementation and design, we delivered a file management and media manipulation solution that meets the diverse needs of our users.✅ Developed robust APIs using Express to support functionalities such as user authentication, data import into our new CMS, and template generation for content management.✅ Maintained and improved HighTower's internal .NET applications.

✅ Assumed the role of the primary developer responsible for overseeing the development of our internal Compliance website and associated applications.✅ Extended the functionality of the client's internal .NET MVC website by implementing new reporting pages.✅ Played a key role in troubleshooting and resolving data inconsistencies within .NET applications that were connected to SQL Server databases.✅ Collaborated on the development of Jefferies' website, leveraging technologies such as .NET for backend development and Angular for the frontend.
