Automation · AI integration · Custom software

If it can be automated, I’ll find a way.

Twenty-four years in sales and operations taught me where businesses bleed hours and money. I build the software that stops it — CRMs, billing, lead pipelines, AI workflows, internal tools. Because I've lived the work, what I build gets used instead of worked around.

About

Every seat at the revenue table, then the build seat.

Rep on the phones, sales manager, operations manager with a P&L, then data and product analyst. There isn't a part of a revenue system I haven't sat on the wrong side of.

I don't hand-write most of what I ship — I direct AI coding agents, review everything, and own every architectural decision. What you're paying for is judgment: knowing what to build, seeing where it will break before it does, and insisting on the unglamorous parts — accurate billing, locked-down data, records you can audit — before anyone asks.

Where this usually starts

Most people don't call me asking for software.

They call because something is costing them money and they can't quite see where. These come up the most, across very different businesses.

You bought a CRM and your team still runs the real work somewhere else.

Two people type the same information into two different systems.

Customers email you for things they should be able to look up themselves.

A new hire waits a week for access, and someone who left last quarter still has a login.

Work stops because something is sitting in an inbox waiting for a yes.

The number you need Monday morning takes someone all of Friday to pull.

You hear about the problem from your customer first.

A payment fails and nobody notices until the customer is gone.

A lead comes in at six o'clock and nobody calls it until Thursday.

The process that matters most lives in one person's head, and nobody else can run it.

If one of those is yours, that's the conversation. It's usually a smaller fix than you'd expect — and if it isn't, I'll tell you that instead.

Engagements

How to work together.

Start here · $1,200/day

Paid discovery sprint

Most take two or three days. You leave with a written scope, a fixed build price, and a date, whether or not I build it. This is where I tell you what you didn't think to ask for.

Core offer

Fixed-scope product build

A product that needs to exist, or a new surface on the backend you already run. One agreed price, one date, one person accountable.

Build

AI features in an existing product

LLM and transcription pipelines wired into real systems — background jobs, cost controls, and a UI people actually use.

Build

Billing & revenue systems

Stripe subscriptions, self-service billing, failed-payment recovery, affiliate programs — and the admin tooling to run it without calling you.

Build

Lifecycle automation & email

Iterable campaigns, onboarding tours, and the prompts that move people from signup to first real use — automation that runs itself.

Retainer

Embedded engineer

A standing block of hours each month, owning a surface outright.

Fastest yes · $750 flat

Same-day data visualization

A dataset in the morning becomes a working interactive visualization by end of day. Fixed price, no meeting, yours to keep.

Not on this list? Ask anyway. Revenue systems are where I'm deepest, but I build custom software generally — internal tools, portals, integrations, a CRM for a business that has outgrown spreadsheets.

Capabilities

What I actually do.

Build

Whole products, start to finish.

  • Full product builds
  • Custom CRMs
  • Data visualization — heat maps to full interactive dashboards
  • Marketplaces with buyers and sellers on one platform
  • Partner and customer portals
  • New features built onto the system you already run

Revenue

Getting the money in, and stopping the leaks.

  • Stripe billing, and automatic retries when a card fails (dunning)
  • Referral and affiliate programs
  • Lead capture, routing and scoring
  • Reporting and dashboards — from a spreadsheet upload to live data

Automation & AI

The work nobody should still be doing by hand.

  • AI features wired into real systems — any provider
  • Call transcription and analysis
  • Onboarding and lifecycle email (Iterable)
  • Jobs that run themselves on a schedule, with spending limits
  • Web scraping, data collection and enrichment

Foundation

The unglamorous parts that decide whether it still works in a year.

  • Public APIs and webhooks, so other systems can plug in
  • SQL and database work, data migrations, admin tools
  • Connects to HubSpot, Slack, Teams, single sign-on
  • Encryption, per-user access controls, rate limiting
  • Data-retention rules and security review

Evidence

Built end to end.

These are the largest builds — the revenue generators — alongside a steady run of smaller automations and internal fixes that quietly delete a manual workday. Everything here is complete and working: the platform runs in production; the other two products I finished and chose not to take to market when my focus changed.

Word of mouth

“Jon helped me build a feature that an enterprise customer was asking for. I thought it was a cool idea but didn’t know how to actually deliver this service. Jon executed flawlessly in a matter of hours — and my customer was so impressed with me.”

Not my scope

Worth saying plainly, so neither of us wastes a call.

  • I don't train or fine-tune models, and I don't do original ML research. I integrate models into products.
  • I don't inherit maintenance of a legacy codebase or debug systems someone else built. New work ships as its own service — alongside what you already run, or with the whole backend built from scratch.
  • I don't manage engineering teams or take a head-of-department seat. I've run sales floors and P&Ls — but hire me to build, not to hold an org chart.
  • I'm not the person for deep algorithmic work or performance engineering. I build business systems.
  • I'll always honor an NDA, and I'll always respect your IP. But I never sign non-competes — at any price. I won't be held back, and everything I learn makes every client's build better.
