SaharshEngineering Log

I build software, design electronics, and run physics simulations around questions in energy, space, and measurement. This site is where I document what I built, what the evidence showed, and what I would change next.

Curiosity about how the universe works leads to better questions, and better questions lead to meaningful work.

Areas I work across

  • Software & Applications
  • Electronics & PCB Design
  • Aerospace & Space Systems
  • Physics & Modeling
  • Quantitative Analysis

Software / Physics / Quantitative

Solar photovoltaic performance intelligence: a deployed application for comparing measured and expected production and investigating persistent underperformance. Public demonstrations use fictional/reference data while the analysis pipeline continues to be validated and expanded.

02Major project

I built and simulated a crossed-nanowire optical detector model in Tidy3D FDTD, using orthogonal NbTiN detector elements inside a multilayer SiO₂ and gold optical stack. The completed V1 run records electric-field distributions and directional flux near 1.55 µm. The crossed geometry was intended to reduce polarization dependence, but the surviving simulation uses only one incident linear polarization — so polarization insensitivity remains a design goal rather than a demonstrated result.

DwellMetry

Physics / Software

DwellMetry is a live home-information application I built to organize a home’s structure, equipment, documents, maintenance history, and utility records in one place. I also used it as a research environment for exploring thermal behavior, expected-performance models, telemetry, and anomaly reasoning, but those scientific features are not presented here as generally available or field-validated product capabilities.

From my reading list

  • Cover of The Gene: An Intimate History by Siddhartha Mukherjee

    The Gene: An Intimate History

    Siddhartha Mukherjee

    I was interested in this book because it treats genetics as both a scientific problem and a human one. What stayed with me most was the distinction between explaining biological influence and treating that explanation as destiny. Its history of eugenics also made the limits of scientific authority feel much less abstract.

  • Cover of Man's Search for Meaning by Viktor E. Frankl

    Man's Search for Meaning

    Viktor E. Frankl

    What stayed with me was Frankl's distinction between circumstances a person can change and those they cannot. I found his ideas about meaning and responsibility powerful, but also important to read carefully: finding meaning in suffering should never become a justification for suffering or a judgment of people who were overwhelmed by it.

  • Cover of The Three-Body Problem by Liu Cixin

    The Three-Body Problem

    Liu Cixin

    I liked the way this novel turns scientific uncertainty into a question about human judgment. The three-body problem, the Cultural Revolution, and first contact all become different versions of the same problem: how confident should we be in an explanation, and what happens when someone acts on it before the evidence is complete?

05Open questions

Things I'm curious about

  • 01How do satellites operate under severe power constraints?
  • 02What can small sensors tell us about complex motion?
  • 03How can mathematical models become useful software tools?
  • 04What happens to matter and information near a black hole?
  • 05How can we design systems that are both simple and reliable?
