Written down.

The parts of building something that never show up in the code: why I picked one thing over another, and what I checked before I trusted it.

SyncState: writing together, even when the internet isn’t there

“Collaborative editors assume stable connectivity. When that assumption breaks, the whole system falters — collaboration shouldn't stop just because the network does.”

AetherScan: trying to make sense of air quality data

“Air-quality data exists everywhere, but it's scattered, inconsistent, and hard to read in one place. It's less about building a ‘feature-heavy’ app and more about building something that stays readable even as the data grows.”

AetherScan: A Quantum-Classical Hybrid Platform for Heterogeneous Air Quality Sensor Fusion and Real-Time Environmental Intelligence

“The research write-up of AetherScan: fusing air-quality readings from heterogeneous sensor networks and showing how much they disagree instead of averaging the gap away.”

Preprint, ResearchGate preprint, 2025

Implementation and Performance Analysis of a Spectral Monte Carlo Path Tracer with Physical Optics Simulation and Adaptive Variance Reduction

“A reproducible validation methodology for a physically-based renderer: BVH-accelerated ray traversal, Monte Carlo path integration, and spectral wavelength sampling, cross-validated against analytical ground truth at 1.81M samples/sec.”

Preprint, ResearchGate preprint, 2025

Geodesic Flow Computation on Parametric Surfaces via WebAssembly: A Differential Geometry Engine with Adaptive Numerical Integration

“A WebAssembly engine that computes geodesic flow, Christoffel symbols and curvature on parametric surfaces in real time, with curvature-sensitive adaptive stepping.”

Preprint, ResearchGate preprint, 2025

Wavelength-Resolved Geodesic Propagation on Parametric Surfaces: Coupling Differential Geometry with Spectral Dispersion

“Couples differential geometry with spectral dispersion — computing geodesic flow and curvature (Christoffel symbols, Gaussian and mean curvature) on parametric 3D surfaces with adaptive numerical integration.”

If you read something and disagree, I would like to hear why.
