About

I'm a software engineer focused on building systems that remove friction from real-world workflows. My work sits at the intersection of AI, healthcare, automation, and infrastructure — from eligibility verification tooling and secure patient communication systems to quantitative analytics platforms and physics simulations.

I'm especially interested in high-leverage software: tools that save time, scale operations, and compound in value as they grow. Lately I've been building automation systems for clinical workflows, experimenting with privacy-focused AI products, and developing infrastructure-heavy personal projects to deepen my understanding of distributed systems and simulation.

Outside of engineering, I spend a lot of time thinking about startups, operational scale, and how thoughtful software can turn repetitive work into intelligent systems.

EligibilityCopilot

Healthcare Eligibility Verification Platform

  • Production
  • Healthcare
  • Automation

Production workflow automation platform used in a psychiatric practice to automate insurance eligibility verification across Practice Fusion, Availity, and CalOptima. The system orchestrates patient verification queues, captures eligibility evidence, generates audit trails, and updates clinical records while preserving human review controls.

Impact

  • Reduced manual eligibility verification from ~10 hours/week to under 10 minutes/week
  • ~99% reduction in manual verification workload
  • Used in production within a psychiatric practice
  • Automated eligibility verification workflows across multiple payer portals
  • Built queue-based patient processing with resumable jobs and retry handling
  • Implemented Playwright browser automation for chart extraction, payer routing, evidence capture, and document updates
  • Added SQLite-backed audit logging, reporting, and human-in-the-loop review checkpoints
  • Python
  • Playwright
  • SQLite
  • Browser Automation
  • Workflow Orchestration
  • Practice Fusion
  • Availity
  • CalOptima

Physics Engine

From-scratch 3D rigid-body engine with constraints and collisions.

A custom rigid-body physics engine built from scratch in C++ to explore real-time simulation, collision detection, and constraint solving. Features broadphase collision culling, SAT-based narrowphase detection, contact manifold generation, sequential impulse resolution, friction modeling, and stable fixed-timestep simulation for realistic rigid-body interactions.

  • Implemented AABB broadphase collision culling and SAT-based narrowphase detection for cube and sphere interactions
  • Generated contact manifolds and resolved collisions using a sequential impulse solver with friction and restitution
  • Designed fixed-timestep simulation, split-impulse position correction, and sleep/wake optimization for stable real-time physics
  • C++
  • OpenGL
  • GLFW
  • ImGui

  • End-to-end encryption with local-only PHI tokenization
  • Auditable retrieval pipeline over de-identified embeddings
  • Role-based access and consent-scoped session memory
  • Next.js
  • TypeScript
  • Python
  • FastAPI
  • PostgreSQL
  • OpenAI
