Navid Nikoo — Software Engineer & Builder

Navid Nikoo.

I build systems that compound.

I'm a software engineer working at the intersection of AI, healthcare, and high-leverage tooling. I care about making real workflows faster, safer, and a little more delightful.

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.

Physics Engine

From-scratch 2D rigid-body engine with constraints and collisions.

A real-time 2D physics engine written from scratch — broad-phase collision detection, sequential impulse constraint solver, and a small demo playground for stacking, ropes, and joints. Built to deeply understand simulation, numerics, and game-loop architecture.

Custom broad-phase with sweep-and-prune for O(n log n) pair pruning
Sequential impulse solver with warm-starting for stable stacks
Deterministic fixed-timestep loop decoupled from rendering

CipherCare

Privacy-first AI assistant for sensitive clinical conversations.

An end-to-end encrypted patient-facing assistant that lets clinicians extend support without exposing PHI to general-purpose models. Combines local pre-processing, encrypted context windows, and audited retrieval over de-identified records.

End-to-end encryption with local-only PHI tokenization
Auditable retrieval pipeline over de-identified embeddings
Role-based access and consent-scoped session memory

Insurance Verification Automation

Availability-first eligibility workflow (in progress).

An in-progress Python automation tool focused on fast insurance availability checks and structured local summaries. Current implementation is Availity-first with SQLite + CSV persistence, with portal abstractions in place for future expansion.

Availability-first flow with clear extension points for additional payer bots
Normalized eligibility fields persisted to SQLite with CSV reporting output
Optional PDF upload workflow to patient documents; EHR write-back is planned
