Enterprise data, automation and software · Miami, FL
I design and build data platforms, SaaS integrations and custom software that run unattended, reconcile to the penny, and ship with tests. Fixed scope, fixed price, half up front.
Services
From $15,000
Pull your SaaS and operational data into one warehouse, model it, and put dashboards on top. Salesforce, HubSpot, call-center and LMS systems into Snowflake, Azure SQL or Postgres.
Fits: operations, finance and sales teams reporting out of exports and spreadsheets.
From $8,000
Connect the systems your team re-keys between by hand. Real-time webhooks, two-way sync, payment and messaging automation, with an event log so every action is traceable.
Fits: firms with 3+ tools that don't talk to each other and staff who copy between them.
From $25,000
A production application from scope to launch: multi-tenant backend, web app, payments, auth and deployment. Built the way I build my own products.
Fits: founders and operators with a validated idea who need a senior builder, not an agency.
From $18,000
An automated trading or market-making system for your own account on Polymarket, Kalshi or a crypto exchange, built the way Polymarket Edge is built: your pricing model, resting-order execution, and risk controls that stop the bot before you have to.
Fits: traders and small funds with a strategy idea and their own capital. You hold the keys and the account; I build and hand over the system, and never manage money or sell signals.
Every engagement starts with a written scope and a deposit. Work begins when the deposit clears. Milestones are defined in the scope, so you always know what's next and what it costs.

About
Senior engineer and founder based in Miami Beach. I've spent a decade building and testing production systems for regulated and high-volume businesses: payments at Verifone, pharma at Bristol Myers Squibb, supply chain at Southern Glazer's, and healthcare CRM integration for a national veteran-services nonprofit.
Since 2020 I've run Jon Bush Enterprises and shipped my own products, so I build client systems the way I build things I have to operate myself: reconciled, monitored, tested, and documented. I'm currently CTO of Espiral USA and co-founder and builder of Moviz and PermitVista.com.

Scoping calls are free and take 30 minutes. You'll have a written scope and fixed price within three business days.
Case study · Proptech
Instant building-permit history for any Florida property.
Open or expired permits derail closings. Agents, title companies, investors and homeowners used to check county portals one property at a time, each with its own search, its own formats and its own gaps. A single missed permit can hold up a sale or land on the new owner.
PermitVista is the same shape as most enterprise data work: dozens of inconsistent sources, a nightly bulk layer plus a live layer, de-duplication, and a product on top that people pay for. I built and operate every part of it.
Case study · Fintech
A cross-border money app for US customers sending to Latin America, the UK and Europe.
Immigrants and small businesses pay 5–8% and wait days to move money abroad. Espiral gives US customers an account, same-day sends, and a way to get paid in dollars.
Money movement is unforgiving. Event stores, reconciliation and kill switches are what let a two-person team operate a payments product safely, and they are what I bring to any integration where the records have to agree.
Case study · Trading systems
An automated market-making and research platform for Polymarket US, running unattended with real capital.
Prediction-market prices lag real information, and small traders can't win on speed. The fee structure rewards resting orders instead. Polymarket Edge earns the maker/taker gap with model-driven quotes and treats risk control as the product.
This is the system I'd point to if you asked whether I can be trusted with production money. It runs around the clock, reconciles to the penny, and stops itself before a person has to.
I build the same kind of system for traders and small funds under the Trading Systems Build engagement: your strategy and your account, with the execution, reconciliation and risk layer proven here. You keep the keys; I never manage money or sell signals.
Case study · Marketplace
A peer-to-peer car rental marketplace for Guadalajara, with optional chauffeurs.
Guadalajara car owners have no local Turo-style marketplace, and renters need Spanish-first booking with deposits and optional drivers. Moviz is that marketplace, built for how rentals actually work in Mexico.
A two-sided marketplace is identity, payments, rules and trust all at once. Moviz shows the full build from auth to release process, shipped by a small team at startup pace.
Case study · Legal tech
A multi-firm legal CRM, billing and client-intake platform.
Law firms lose leads and fees across disconnected tools and manual follow-up. JuryFlow brings intake, case tracking and billing into one platform for firm owners, intake staff and billing teams.
Multi-tenant isolation and two-way sync with incumbent systems are the hard parts of any vertical SaaS. JuryFlow is that pattern applied to legal; the same architecture fits any industry with entrenched tools.
