Engineering distributed NLP systems and production-grade testing infrastructure for large-scale nonprofit document intelligence, with a focus on LLM orchestration and pipeline reliability.

• ▹Engineered a 3-stage distributed NLP pipeline processing 5,000+ nonprofit tax documents using Mistral-7B and Gemma-7B, orchestrated via Slurm job scheduling with idempotent checkpointing, automatic stage-to-stage handoffs, and per-record structured logging for full pipeline observability.
• ▹Refactored codebase for production readiness consolidated duplicate model interfaces into shared libraries, migrated credentials to environment-based config, and built an end-to-end testing architecture using security-focused prompt engineering and LLM-assisted code generation to surface adversarial inputs and reduce manual QA effort.

Developing cross-platform AR/XR applications in Unity across mobile and headset devices, with a focus on spatial interaction, real-time rendering, and production-grade deployment reliability.

• ▹Built multi-platform AR/XR Unity applications targeting iOS, Android, and Meta Quest 3 using AR Foundation, ARKit, ARCore, and OpenXR delivering consistent spatial experiences across device families.
• ▹Implemented real-time geometric visualization, spline rendering, hand-tracking interactions, and procedural mesh systems that define how users physically engage with immersive environments.
• ▹Designed scalable C# architectures with automated testing pipelines, structured debugging workflows, and reusable spatial systems reducing regression issues and ensuring cross-device reliability at every release.

Supported students in software development and computer graphics through technical mentorship, code review, and project guidance across AR and MR workflows.

• ▹Mentored 10+ students in software development and computer graphics with 1:1 feedback on code quality, debugging, and design.
• ▹Guided multiple AR and MR teams through the full SDLC using C# and Unity.
• ▹Supported project execution from requirements gathering through testing, documentation, and iteration.

Built and shipped a React + TypeScript learning platform while leading a 10-member team through frontend, backend, authentication, and delivery planning.

• ▹Built and shipped a React + TypeScript LMS serving 50+ users with responsive UI, Firebase backend, authentication, and real-time data sync.
• ▹Led a 10-member team end-to-end and delivered all major features on schedule.
• ▹Engineered 10+ reusable React components with React Router to reduce future development time for similar UI patterns.
• ▹Implemented unit testing and debugging workflows to maintain production reliability.
