Work Experience

Software Development Engineer 1 (SDE-1)

Arrise Solutions

Jul 2024 - Sep 2026

Engineered a dynamic theming system in React.js and CSS that algorithmically generated 20+ UI shades from 4 backend-supplied primary colors in real time, replacing a hardcoded color/shade system and enabling operators to rebrand the UI without frontend code changes. Built a custom side-bet input component in React.js with real-time validation (blocking text, negative, and invalid values) that let users enter any valid numeric bet, replacing a fixed preset pattern (0, 1, 2, 5, 10...) and increasing betting flexibility. Designed and shipped a responsive React.js virtual keyboard component to support free-text bet entry on touch and mobile devices, extending the side-bet feature across device types. Converted a statically hardcoded 2-minute race timer in the React.js game UI into a fully dynamic, API-driven countdown supporting variable race durations (1-7+ minutes). Performed 15+ peer code reviews, identifying and resolving 7+ bugs prior to production release on a platform serving 7,000-8,000 daily active users (10,000+ on weekends/holidays). Partnered within a 35+ member cross-functional department (backend, QA, 3D, PM) to translate business requirements into pixel-perfect, accessible interfaces across Agile sprint cycles.
