Kintsugi Mindset. Kaizen Execution.

I cannot walk past a broken thing and leave it broken. From fractured business systems to the families who depend on them, my work is finding what's hurt, rebuilding the foundation, and making sure it holds.

About

My first love was biology.

The connections. The alien mitochondria in our cells, powering our lives. The autonomic coupling synchronizing heartbeats. A park's entire landscape changed when wolves were reintroduced, because the deer moved differently, and the rivers changed course, and the willows grew back along the banks. A single flower feeds a bee and in return gets carried somewhere new. One small village in England carried a genetic variation that made them immune to the Black Plague, and centuries later, to HIV. How nature responded to malaria not with a cure but with a negotiation, a cell deformation that offers protection with one allele. How you can still see the shape of Pangea in the way South America fits against Africa's coast.

I loved that it was all connected in ways you couldn't see until you knew where to look. That invisible hand working underneath everything, keeping the balance or breaking it.

The thing I couldn't figure out in college was where I fit into pursuing it. The methodology fascinated me. The application hadn't arrived yet.

Then I found accounting.

The systems. The flows. The triggers. The patterns. The dependencies. The formulas. Suddenly the methodology had somewhere to go. I barely slept. I dreamed in Excel formulas. As fast as my mentor could show me spreadsheets I devoured them, analyzed them, rebuilt them to flow better. I fixed simple ordering to make references automatic. I created formulas that did the work and fed the data forward to the next sheet. When I made a mistake, I analyzed it and updated the sheet so that mistake became structurally impossible. The hunger was greater than my capacity and I didn't care.

I rose fast. Accounting Assistant to Senior Staff Accountant and NetSuite Administrator within a year, building an AR department from nothing, automating most of it, running it alone. The Controller and CFO called me to run automation ideas past me. My mentor once said it was like the company had been careening in a speeding car and I fixed everything I touched as I bounced around inside the vehicle. That felt accurate.

It was like the Queen's Gambit. That small lit space where everything makes sense and you can block out the rest. Building, fixing, maintaining systems and keeping them flowing. That is my ikigai. I go to sleep thinking about automations. I wake up to build the next one.

But an environment is only as healthy as what grows in it.

I watched what happened when the wrong thing went unchecked. Leadership at one company saying openly that they should burn through employees if it meant better profit margins. A CFO whose focus had shifted so far toward numbers that the people generating them became more numbers. I had poured everything into those environments, my health, my sleep, my social life, all of it. And I had seen enough biology to know what was happening. An invasive species growing unchecked doesn't just crowd out what was there. It reshapes the entire ecosystem.

Diversity, balance, interdependence. These are not soft values. They are survival mechanics.

So I stopped waiting for a healthier environment and built one.

ClearStem Systems Consulting exists because I will only work in ecosystems where people are the purpose. Not as a side effect of the mission. As the reason for it. One nonprofit partner is building infrastructure so that families in crisis can access the support they need and begin to break cycles of poverty. Another is an independent studio creating a game that is ambitious and meaningful in looking at living life with honor. I am there with them, and we are building environments where people can grow and thrive.

I bring the same thing to every engagement. Find the root. Fix what's broken. Build something that empowers people. And I only do it in places where the goal is for living things to flourish.

That is applied biology. It just took me a while to find the right ecosystem to practice it in.

By the way, the cat's name is Ferris Mewler. Unfortunately, he is not available for consulting engagements.

I am Heather Sherman, here when you need me.

Senior Cost Accountant, FloQast Implementation Lead  ·  Middle Tennessee

Under 10 days Month-end close, down from 2 to 4 weeks

A fast-scaling private equity-backed company whose financial close process hadn't kept pace with its growth. Some accounts had gone unreconciled for three to four years. There was no formal close process, no segregation of duties, and documentation lived wherever the nearest person happened to keep it. I was brought in for my NetSuite expertise and immediately saw the bigger picture.

Led the FloQast implementation end to end: designed the reconciliation framework, automated lease clearing and commission reclassification workflows, and resolved a multi-year GRNI backlog using a custom NetSuite SQL search combined with Excel and FloQast AI Transaction Matching. Closed the segregation of duties gap through Journal Entry Management. Auditors now self-serve all documentation directly in FloQast without involving the accounting team at all.

Selected by FloQast as a featured customer voice: published case study, two webinars, and a panel discussion. Core message: automation amplifies the foundation you give it. Read the case study →

High-Growth Member Benefits Platform

Accounting Assistant, promoted to Senior Staff Accountant and NetSuite Administrator  ·  Remote

There was no accounts receivable department when I arrived. There was a fast-growing company, a Controller navigating chaos at speed, and a gap where a system should have been. Within a year I had been promoted multiple times, was running automation strategy alongside the CFO, and had built an AR department that operated as a department of one because most of it didn't need a person anymore.

Custom NetSuite saved searches ran on automated schedules and emailed results without anyone touching them. Mass imports mapped perfectly to vendor and payment records, saving hours of manual entry per cycle. Excel workbooks tracked vendor obligations across affiliate marketing campaigns with enough precision that the company recovered bank errors it didn't know it was owed, more than once. When a colleague went on leave I absorbed their workload. When they returned, I handed it back faster, more accurate, and documented well enough that I was no longer a dependency.

My mentor, the Controller who first showed me what systems could do, once told me during yet another automation fix that it felt like the company had been careening in a speeding car and I fixed everything I touched as I bounced around inside the vehicle. This is where the spark became a direction.

Some engagements are professional. This one is also personal. The founder of this studio was my mentor during the most formative chapter of my career. He was the person who first showed me what systems thinking looked like at its best, who watched the obsession develop in real time, and who, years later, chose to trust me with his life's passion project. That kind of invitation carries weight.

The studio is building an ambitious, complex tactical game with layered systems that require the same kind of careful architecture as any enterprise build. Creative vision at this scale doesn't fail because the ideas aren't good. It fails when the underlying structure can't hold the weight of them.

Before a single line of code was written, I delivered a fully organized build plan in Notion: a structured project hub covering character databases, unit and class systems, a decisions log to capture design intent over time, a kanban project board for active development tracking, and scope documentation to keep the vision legible as it grows. The goal was to give the studio a foundation that could scale with the ambition rather than buckle under it.

Engagement covers data architecture, systems legibility, UI/UX consultation, knowledge organization, and GitHub repository management. Active and ongoing.
