Open to new operations roles

Nathaniel (Nate) Eisenstein

Operations — Chicago, IL

I'm Nate — an operations manager who takes a messy, high-stakes process and gets it running quietly and on time. Over the past ten years that's meant banking operations and compliance at AngelList, and facilities and inventory for Forward's health clinics.

The part I like most is the people. I've coordinated work across engineers, bankers, healthcare workers, vendors, and clients, and I'm good at getting a room full of different priorities onto the same page — then holding everyone to the SLA and escalating quickly when something slips.

Lately I've been learning to build and ship small tools with AI. This site is one of them — more on that just below.

About this site

I built this to see whether I could take a simple idea and actually ship it — approaching it the way I'd approach any operations problem: define the outcome, break it into steps, use the best tools available, get it live.

I'm not a developer. Every part of it was designed and built by directing an AI assistant (Claude) in plain English. The code lives on GitHub and it's hosted on Vercel, which republishes the site automatically whenever I change something. When I want an edit, I describe it in a sentence and it's live a minute later.

The projects below are an extension of the same idea. Each is a small operations tool built the same way, and each is doing three things at once: making me faster and more fluent with AI, showing I can take a concept from idea to working product on my own, and putting my own spin on tools I've relied on and operated in past roles. Rebuilding a tool from scratch, it turns out, is the best way to understand how it really works.

Projects

Small operations tools I've built by directing an AI assistant in plain English — experiments, really, running on invented data for the practice. But each is a real, working tool that could be pointed at live data and used for the job it describes.

Clinical Coverage Planner

Live

A weekly staffing board for a network of clinics plus 24/7 nurse telemedicine. You assign people; it flags coverage gaps and rule violations (double-booked, over hours, too little rest, off their home clinic), prices the week against an editable pay scale with shift, weekend, and market differentials, and writes a daily digest for the clinic leads. It's the manage-and-validate core — auto-scheduling is the next piece. Single-page app on fictional data; it comes out of running operations for a 30-clinic network at Forward.

Clinical Supply Tracker

Live

An inventory tracker and reorder tool for one clinic's stockroom. It holds each supply between a par min and par max, turns weekly usage and supplier lead times into a reorder list grouped by vendor (copy, CSV, or email), and keeps a separate watch on the dated stock — vaccines, medications, test kits — flagging lots before they expire. Single-page app on fictional data. Another one from the Forward facilities-and-inventory work, where I ran an $80–100K monthly supply budget.

SLA & Escalation Tracker

Live

A working ticket queue that tracks every SLA. Add or import tickets, see what's breached or about to be, open any ticket to edit it and read the requester thread, and generate a morning digest — a visual summary with every ticket linked back to itself. Built as a single-page app; the demo runs on fictional data in your browser. It grew out of the facilities-SLA work at Forward, where I took response time from 12 days to 1.

Job Search Tracker

Live

A spreadsheet that runs a job search like an operations pipeline: company, contact, stage, and status per row, with a dashboard that auto-calculates the funnel, response and interview rates, and what's overdue. Built in Google Sheets — I use it for my own search. This copy is filled with dummy data.

Also planned

  • CSV reconciliation helper — upload two files, get the mismatches explained in plain English
  • Meeting notes → action items — messy notes in, an owner/task/date table out

Build log

A running log of what I'm figuring out as I build — what worked, what broke, what I'd do differently. Each entry has a rough estimate of the time it actually took.

  1. Built the Clinical Supply Tracker

    Sep 10, 2026

    Roughly a day, spread across sessions

    An inventory tracker and reorder tool for clinical supplies. Each item sits between a par min and par max; when on-hand drops to the min it lands on a vendor-grouped purchase list, sized to refill up to the max in whole packs. The part worth getting right was the split between supplies that expire and supplies that don't — the perishables track individual lots, get consumed first-expired-first-out, and surface on an expiry watch well before the date, which is closer to how a stockroom actually loses money.

  2. Built the Clinical Coverage Planner

    Sep 10, 2026

    Roughly a day

    A staffing board for a clinic network plus 24/7 nurse telemedicine — you assign people, it flags coverage gaps and rule violations, prices the week, and writes a daily digest for the clinic leads. It grew in layers over a day: the coverage grid first, then the rules engine, then an editable pay scale, then the digest, each one added by describing it in a sentence or two. The fiddly part was the shift model — daytime clinic blocks alongside three telemedicine bands, one of which runs past midnight — and keeping every check consistent across the grid, the issues list, and the digest.

  3. Built the SLA & Escalation Tracker

    Sep 9, 2026

    About half a day

    Started as a paste-in report; ended up a small working ticket queue — editable rows, a comment thread per ticket, CSV import, a visual morning digest, and every ticket in the digest linked back to itself. The interesting parts were separating the SLA state (breached / at risk) from the workflow status, and making it a proper sandbox so anyone can poke at the demo without breaking it for the next person.

  4. Built the Job Search Tracker

    Sep 9, 2026

    A few hours

    A Google Sheets pipeline for my own job search — a dashboard tab that computes the funnel and conversion rates off the data, dropdowns, and colour-coding. Most of the work was the model: keeping "how far it got" separate from "how it ended" so a late rejection still counts in the funnel.

  5. Built and shipped this site

    Sep 8, 2026

    An afternoon to get it live; refined since

    Went from nothing to a live site by directing an AI assistant in plain English — Next.js for the site, GitHub for version control, Vercel for hosting. First time touching any of them. The hard part wasn't the code; it was deciding what I actually wanted on the page.
