A full stack developer in Toronto

Full Stack Developer (2021-Present)

Milborne Group

As a Full Stack Developer at Milborne, I enhance and maintain a real estate sales web app, where I resolve bugs, elevate code quality, enrich user experiences, and integrate new functionalities and features.

• Successfully planned, designed, and developed features to automate new project setups, significantly cutting down on manual tasks and redirecting the development team’s focus to more strategic initiatives.
• Independently built a feature that allows admins to customize purchase and sale agreements by using unit and deal details as conditions to dynamically insert specific documents at designated points within the contract. This ensures each deal is fully customized.
• Actively and consistently proposed and implemented UI enhancements to boost visual experience and usability. This includes designing tables and chart reports that improved data analysis and visualization, thereby facilitating decision-making.
• Independently redesigned the entire app utilizing Material UI styles in accordance with a newly established brand identity provided by a design agency, bridging the design gaps for areas that were not covered, ensuring a seamless and consistent design throughout the app. See before/after screenshots.
• Developed a reusable and performant autocomplete form field component optimized for loading and searching through over 5,000 brokers. The backend features a GraphQL resolver with MongoDB aggregation for dynamic full name concatenation and efficient filtering. I implemented pagination and sorting directly in the database, significantly reducing page loading times while delivering both sorted results and total match counts in a single query. On the frontend, I designed an advanced autocomplete interface using React and Material-UI's TextField and Popper, tailored for enhanced usability with custom styles and keyboard accessibility. It includes a debounce mechanism for the search input to minimize server load and improve responsiveness. I integrated the IntersectionObserver to implement infinite scrolling, seamlessly loading additional data as the user scrolls. This approach, combined with the ability to cancel obsolete requests via the AbortController, ensures that the UI remains efficient and responsive to user interactions, even with large datasets.
• Designed and developed a feature that tracks opened emails using a tracking pixel embedded in the email's HTML. When an email is opened, this pixel triggers a GET request to the '/emailOpen' endpoint, retrieving a transparent GIF and transmitting key details via query parameters. The server processes these requests, updates the activity log, and records the email opening, providing essential real-time data to ensure purchasers have received their documents.
• Planned and developed an AWS Lambda function that executes daily late at night, connecting directly to MongoDB to collect and compile statistics on real estate transactions. This function assesses realtor performance by tracking metrics such as the number of units sold, worksheets submitted, and deals rescinded, providing insights over specific periods, including the last 7, 30, 90, and 365 days. These analytics assist in performance analysis and support strategic business decisions.
• Successfully upgraded the app to the latest versions of Node, React and Material UI, which involved handling significant breaking changes related to the React Hook Form library, MUI Date Component and Apollo Client.
