“Unity game developer with hands-on experience building high-impact gameplay feel features (cinematic slow-motion bullet-follow sniper mechanic) and shipping a cross-platform multiplayer word/voting game (ACROMANIA) using Photon PUN. Has also worked on Unity WebGL pipelines involving VRM model uploads and heap memory crash diagnosis, and uses AI tools (ChatGPT/Gemini/Claude) to accelerate debugging and understanding of complex code.”

“Frontend lead on a campaign management platform, owning architecture and delivery in Next.js (App Router) with TypeScript types derived from Swagger contracts and Zustand state management. Built and shipped complex, form-heavy multi-step flows like QR code creation with live preview/analytics considerations, and improved maintainability by extracting shared table/filter abstractions while proactively defining UX edge states with design.”

“Frontend engineer who led an employee management system end-to-end, focusing on scalable architecture and performance (caching, route/component-level code splitting, lazy loading, dynamic imports). Experienced building React + TypeScript dashboards with Tailwind CSS and Zustand, including centralized global UI state for modals/sidebars/preferences and feature-flagged rollouts with rapid QA/iteration.”

“Full-stack engineer with experience delivering an end-to-end NIH application using Angular and scalable .NET Core microservices backed by MySQL.
