Quentin Neal
Software Engineer
Hello! I’m Quentin, a Software Engineer with 3+ years of professional experience specializing in frontend development with React, TypeScript, and Next.js.
I build customer-facing applications with an emphasis on maintainable architecture, accessible interfaces, performance, and polished user experiences. My strongest specialty is frontend engineering, supported by deep CSS expertise and experience with design systems, reusable component architecture, API integration, and debugging across frontend and backend systems.
Before entering software engineering, I worked for Hilton in Seattle for nearly five years, and I've found that creating great hospitality experience and a great web experience are not so different from one another and that is the philosophy I bring to my work.
Outside of programming, I like to engage in amateur astronomy, traveling, gaming, movies and use VSTi (Virtual Studio Technology instruments) to produce sounds in FL Studio.

Infange is a real-time collaboration platform built with Next.js and .NET that brings calendars, agendas, notes, organization management, and other team workflows into one application.
As the primary frontend engineer for the second version of the platform, I helped establish a more focused and maintainable foundation after contributing to the original React and Node.js implementation. I owned the core frontend architecture, shared interface patterns, API integration, and much of the implementation across the application.
I built reusable components for navigation, forms, calendars, agendas, notes, settings, and account workflows. I also implemented client-side REST and WebSocket integrations and contributed to select backend endpoints when needed. The new approach reduced expected delivery time by approximately 75% while improving maintainability, interface consistency, and product readiness.
One of my most significant contributions was creating the calendar interface without relying on a third-party calendar component. I combined flexbox and absolute positioning to display meetings accurately across daily, weekly, and monthly views. The calendar handles overlapping meetings, expandable navigation, hover details, meeting creation, and a live horizontal timeline marker.
Additional work included:
- Multi-step account creation and authentication flows
- Agenda creation, editing, deletion, reordering, and rich-text support
- Notes and folders with autosaving and reordering
- Organization and profile-management interfaces
- Shared UI components and design patterns
- Ongoing maintenance, debugging, and performance improvements

Net Pay Advance is an online financial-services platform built with React and .NET that supports customer applications, loan servicing, payments, authentication, document signing, and account management.
I maintain and expand both the customer-facing application and the private support portal used by customer-service teams. My work includes frontend feature development, production debugging, API integration, backend endpoints, SQL queries, stored procedures, database migrations, authentication workflows, and deployment tooling.
A major contribution was rebuilding new- and returning-customer application flows. I improved multi-step React interfaces, form validation, API integrations, application state, and rendering performance. These changes contributed to a 15% increase in onboarding conversion.
I have also built reusable Material UI components, custom hooks, and shared interface patterns across multiple applications. This work improved consistency, code reuse, and maintainability while making complex customer workflows easier to extend.
Additional contributions include:
- Improving Core Web Vitals and Interaction to Next Paint
- Resolving payment and debit-card submission issues
- Improving authentication, MFA, and session restoration
- Supporting loan agreements and e-signature workflows
- Enhancing returning-customer and lead application flows
- Maintaining collections and past-due servicing tools
- Contributing to regulatory and adverse-action workflows
- Supporting Azure configuration, build, and deployment processes

This portfolio was designed and developed to demonstrate my CSS, interface-design, and frontend implementation skills.
I built the site with HTML, CSS, and JavaScript because its focused scope did not require a larger application framework. This kept the implementation lightweight while giving me direct control over the browsing experience, visual presentation, and interaction design.
The primary focus on this site was to attempt to use the sticky feature of CSS to create a unique browsing experience that also improves UI/UX experience compared to normal methods. I also included video and animations to enhance the experience.
I took a particular interest in optimizing images and videos to ensure the website loads fast, and the users have a positive browsing experience.
