Harmoic App was a 6-month developed using the same infrastructure and technology stack as Beanstalk Benefits. It serves as an internal web application tool focused on providing encounter assistance to patients and managing their health data efficiently. The app integrates deeply with existing healthcare systems used by the company to ensure seamless data flow and operational continuity.

Patient data ingestion began with CSV file imports. These files were rigorously validated and parsed before being handed off to an asynchronous processing pipeline built with NestJS and Bull on Redis. This pipeline orchestrated data synchronization across multiple external systems, featuring retry policies to ensure reliability and data consistency.

Healthie served as the primary source of patient data, providing comprehensive health records. Zus was integrated to register and manage patient encounters effectively. The app also connected with Awell to trigger patient workflows, ensuring that all necessary actions were taken based on the data received.

This robust integration ecosystem allowed Harmoic to streamline patient management workflows, reduce manual data handling, and improve the accuracy and timeliness of health information across platforms.

Beanstalk Benefits was a 1-year project under Redesign Health, developed by a highly skilled, fully autonomous senior team in close partnership with stakeholders. The initial vision was to create a user-customized health benefits platform leveraging Slack API integration to dynamically convert FHIR forms into interactive Slack message flows. These flows collected user preferences and later presented personalized benefits within the platform for selection, payment, and ongoing management.

The platform was built as a modern full-stack SPA using the latest frameworks and tools. Midway, due to challenges in securing investors, the project pivoted to a health benefits marketplace, partnering with other companies to launch initial offerings and gather early user feedback. The marketplace retained the same architecture, integrating Directus CMS to allow stakeholders to easily customize benefits and related content, ensuring dynamic and flexible presentation.

Designed, developed, and deployed entirely from scratch, the solution featured a robust and scalable architecture. Cloud infrastructure utilized AWS services for hosting, storage, and security, with automated provisioning and deployment pipelines managed through Terraform for consistency and repeatability. The production-ready platform was built for high availability, performance, and maintainability.

Figma designs were seamlessly integrated into the workflow, ensuring pixel-perfect implementation. A cohesive design theme maintained visual consistency, with design tokens and styles translated into a scalable TailwindCSS configuration. UI development was enhanced using ShadCN components for rapid, consistent, and accessible interfaces.

HIPAA compliance was implemented across AWS infrastructure, leveraging Vanta for automated monitoring and reporting. Continuous security checks, access controls, and encryption safeguarded sensitive healthcare data. Compliance workflows were streamlined to meet audit requirements and industry standards efficiently, ensuring the platform maintained high availability while adhering to strict healthcare data protection regulations.

At Adobe Workfront, I worked on modernizing a legacy web application that serves as a core part of the company’s enterprise work management platform. This application enables teams to plan, track, and collaborate on projects and tasks across the organization, providing critical tools for project scheduling, resource allocation, and workflow automation.

I led efforts to migrate proprietary components and design systems to ReactJS with React Hooks, significantly enhancing maintainability and developer productivity. A key part of the work involved the un-shimming migration process, which facilitated smoother integration with modern tooling and frameworks—accelerating feature development and reducing technical debt.

Alongside the migration, I designed and implemented new features while refactoring existing code to improve performance and scalability. The backend was developed using Java and Spring Boot, with frontend technologies including JavaScript and TypeScript, delivering a robust, full-stack solution. Working closely with cross-functional teams, I helped ensure smooth deployment cycles and high-quality releases. This modernization resulted in improved application responsiveness, fewer bugs, and a better user experience, supporting Adobe Workfront’s mission to streamline enterprise project management and collaboration.

Throughout development, comprehensive metrics were tracked to compare the new solution against the legacy system. Performance benchmarks, error rates, and user engagement data were continuously monitored, demonstrating clear improvements in speed, stability, and usability, which validated the success of the modernization effort.

I developed a food delivery marketplace web application targeting NYC restaurants for Aurify brands (Meltshop, Fields Good Chicken, and The Little Beet). This application was built with modern frontend technologies such as JavaScript, TypeScript, React with React Hooks, Context API, Material UI, HTML, CSS, and Styled Components.

Integrated with OLO for order management and delivery logistics, the platform enabled restaurants to handle orders efficiently from placement to fulfillment. Supported by a robust CI/CD pipeline powered by GitHub Actions, it was deployed using AWS S3 for hosting and AWS Lambda for serverless backend processing. The architecture was designed for scalability, high availability, and cost efficiency, ensuring consistent performance under varying traffic loads.

Developed as a white-label platform to be reused across multiple brands, it proved highly effective, as demonstrated by the successful implementation of the Le Pain Quotidien version. PCI compliance was achieved through secure payment processing, ensuring that all transactions met industry standards for security and data protection.
