# Bill Greco > Software Engineer Location: New York City Metropolitan Area, United States Profile: https://flows.cv/billgreco Experienced software engineer with a passion for working with new technologies and solving complex problems. Full-Stack Engineer at Florence Healthcare helping to enable sites and accelerate cures. Other experiences include building and deploying highly-functional, user-friendly, full-stack products incorporating JavaScript/ES6+, TypeScript, Angular, Node.js/NestJS. ## Work Experience ### Staff Software Engineer @ Florence Healthcare Jan 2025 – Present ### Senior Software Engineer @ Florence Healthcare Jan 2022 – Jan 2025 • Managed application state using Angular's dependency injection system to facilitate separation of concerns and maintainability in a container/presentational component architecture, ensuring efficient data flow and code organization • Implemented lazy-loading techniques in Angular single-page application (SPA) to enhance user experience by drastically reducing initial load times and packet sizes, resulting in a faster and more responsive web application • Reorganized Angular codebase by structuring it into discrete single-component Angular modules, streamlining code maintainability, enhancing reusability, and enabling more efficient development and testing processes • Composed declarative, reactive data streams leveraging the RxJS library to handle complex asynchronous data fetching and state transformations using the observer pattern • Developed a backend server-side application using Node.js framework NestJS, harnessing NestJS’s powerful dependency injection system, decorators, and module-based architecture, to create scalable, efficient RESTful API endpoints that retrieve resources and handle business logic demands of both the client application and API users • Utilized TypeORM as an abstraction to the data layer to seamlessly define and manage complex relationships between entities within a PostgreSQL database, ensuring data integrity and optimizing query performance • Integrated Orkes workflow orchestration into feature architectures to accelerate development speed and reduce complexity of creating simple microservices to perform isolated tasks or communicate between different services asynchronously and robustly • Authored detailed technical specifications for new features, providing a structured framework to guide development priorities and comprehensively documenting key architectural design decisions ### Software Engineer @ dangoDB (Open Source) Jan 2022 – Jan 2022 | New York, United States • Engineered a MongoDB object data modeling library for Deno to enable developers working within Deno to manage relationships between data and provide non-relational database schema validation for database consistency while taking advantage of quick query times of a document-based system • Built the ODM codebase employing factory and facade design patterns to efficiently instantiate objects for the purpose of schema generation and to encapsulate the complexities of the library • Incorporated Deno's native testing suite, facilitating the implementation of behavior-driven unit tests featuring setup/teardown hooks. This approach allowed for the logical grouping of tests around desired behavior, resulting in heightened confidence in the correctness and reliability of the ODM functionality • Constructed product landing page using React with functional, reusable components to enable manipulation of the virtual DOM for efficient diffing-algorithm based reconciliation of conditionally rendered items for a dynamic, interactive user experience • Integrated React hooks with lifecycle methods to initially fetch and populate previous application state and to dynamically re-render components on stateful changes • Product developed under tech accelerator OS Labs (opensourcelabs.io) ### Engineer @ Air Products Jan 2014 – Jan 2022 • Programmed calculator blocks with Fortran within Aspen Plus to simulate and optimize air separation and hydrocarbon processes, minimizing compressor power consumption and maximizing product recovery • Created VBA scripts within Excel process calculation templates to automate dynamic calculations and pull historical plant data ## Education ### Master of Science (M.S.) in Chemical Engineering Villanova University Jan 2013 – Jan 2014 ### Bachelor of Science (B.S.) in Chemical Engineering Villanova University Jan 2009 – Jan 2013 ### Master of Science in Computer Science Georgia Institute of Technology Jan 2025 ## Contact & Social - LinkedIn: https://linkedin.com/in/bill-greco - GitHub: https://github.com/wgreco13 --- Source: https://flows.cv/billgreco JSON Resume: https://flows.cv/billgreco/resume.json Last updated: 2026-03-29
