Software development for Chicago companies
Your integration project has stalled because nobody on the team has time to make five systems agree on one order. Our senior engineers join the roadmap, build the platform and the event log behind it, and stay to run it in production. Chicago puts that problem in the trading firms by the Board of Trade and the manufacturers of the south suburbs, and an insurer in Schaumburg or a hospital group meets it too.

Derivatives and futures trading on LaSalle Street and Wacker Drive, heavy manufacturing across the south suburbs and northwest Indiana, and the rail and intermodal yards around Joliet that connect both to everywhere else. If your company sits where regulated finance meets physical logistics, and in Chicago many do, every automated action has a clock and a counterparty.
AzureTechFabric is a Databricks partner with an award-winning Databricks engineering team, 80 of them Databricks-certified, and a Temporal partner. Where a system reaches past the workspace we build on Azure, AWS and Google Cloud.
What software development covers
Web applications
Applications built to be changed safely years after the original team has moved on. That means tests that mean something, seams where the business logic can move, and a deployment nobody is afraid of.
Mobile applications
iOS and Android, built as products rather than as ports. The maintenance story is decided at the start, while it is still cheap.
APIs and integration
The seams between systems, done once and properly. Most of the expensive failures we are called into are integration failures wearing another name.
Data platforms
The layer underneath the application, on Databricks, Azure, AWS or Google Cloud. If the reporting and the application disagree, the platform is the reason.
Modernisation of what exists
Often the work arrives as something already built that has become hard to change. We would rather read it and tell you honestly whether it is worth keeping than sell a rewrite you may not need.
Durable, auditable workflows
Processes that take days, call several systems and must never half-complete. Getting that right is a different discipline from getting a request handler right, and it is where we spend most of our time.
Mobile and web apps for Chicago companies
You've got a launch date and an MVP that falls over once real users and orders hit it.
App development in ChicagoDynamics 365 consultants in Chicago
Manufacturers and distributors across Chicagoland, from the industrial park in Elk Grove Village by O'Hare to the steel and chemical plants of northwest Indiana, run Dynamics 365 Business Central for production, inventory and multi-site finance. We implement it with Dynamics 365 CRM, connect it to freight, EDI and warehouse systems, and give operations Power BI reporting that ties to the general ledger.
Every trade has to reconcile
In Chicago, CME Group runs its futures exchanges from Wacker Drive, Cboe sits a few blocks away on Van Buren, and the trading firms around the old Board of Trade building on LaSalle reconcile every day. CFTC Rule 1.31 keeps their records for five years, and SEC Rule 17a-4 holds broker-dealers to the same discipline, so a position that can't be rebuilt from its history is a finding.
A table of current positions with an audit table beside it is the common design, and month-end goes on explaining why the two disagree. We make the event log the record instead. Every position and report derives from it, and a wrong projection is rebuilt by replay rather than patched by hand. On a desk that reconciles daily, that's an hour against a week.
Design starts from the events themselves. We name every one a trade or an order can emit, agree which system may write each, and replay a week of production history against the new model before anything is cut over. Freight and manufacturing firms get the same treatment, with a shipment or a work order where the trade was.
Clients we have done this for
If your orders, customers and invoices live in separate systems that have to agree, this is the study to read. AmTab's orders reach Business Central from the store without anyone re-keying them, and Power Automate keeps the store, the CRM and the ERP holding the same records.
B2B ecommerce
AmTab
AmTab, a table manufacturer, had orders moving between departments on paper while demand climbed. Senior engineers from TechFabric worked through those manual steps with AmTab's own people first, then connected the amtab.com store, the CRM and Business Central, so an order placed online reaches the ERP that invoices it without anyone retyping it.
How an engagement runs
01
A technical conversation
Not a sales call. An engineer, asking what you are trying to do, what has been tried and what it will actually take. Where the work needs them, product and design people join the same conversation.
02
Two weeks, fixed fee
A short assessment ending in a written plan with a scope, a sequence and a number. You own the document whether or not you carry on with us.
03
Build with your team in the repo
Senior throughout, and no pyramid with one architect over a floor of juniors. The person in your standup is the person writing the code.
04
Run it
We stay on the pager. Nobody designs a fragile thing they will personally be woken by, which is most of why this arrangement produces different software.
Two weeks, fixed fee, and a written plan whether or not you build it with us.
Tell an engineer what you want to build
A senior engineer reads it and replies within one business day, usually with the questions that decide the first two weeks.
Around Chicago
Chicago's developer calendar
ChiPy, the Chicago Python User Group, has met since 2003, usually on the second Thursday and in a different host company's office each time. Digital Delivery Chicago, the old Chicago JavaScript group, meets monthly on Tuesdays at the Aon Center. The bigger dates are further out, with PG DATA bringing Postgres people to UIC in June 2027 and DevOpsDays Chicago at the UIC Forum that August.
Because ChiPy moves between host offices, a year of its nights is a tour of which Chicago companies run Python in production and how their teams are laid out. Digital Delivery Chicago is the rarer room, with QA engineers and product owners next to the developers, and the release arguments it has are the ones a commissioned platform will meet in its first month live.
The Chicago-Naperville-Elgin metro area. Illinois: Cook, DeKalb, DuPage, Grundy, Kane, Kendall, Lake, McHenry and Will counties. Indiana: Jasper, Lake, Newton and Porter counties.
Lighter shape: the city itself. Dot: downtown. County boundaries from the US Census Bureau, 2023.
User group · Monthly, usually the second Thursday evening
Chicago Python User Group (ChiPy)
Founded in 2003 and hosted by a different company most months, ChiPy doubles as a tour of who runs Python in production across the city.
Chicago Python User Group volunteers. Rotates between host companies' offices in Chicago.
Meetup · Monthly, Tuesday evenings
Digital Delivery Chicago (formerly Chicago JavaScript)
QA engineers and product owners sit beside developers at the Aon Center, so the release arguments you hear are the ones your own platform will have.
Volunteer organisers. Aon Center, 200 E Randolph St, the Loop.
Conference · 11 to 12 June 2027
PG DATA 2027
If your event log or read models will live in Postgres, two days at UIC next June put you with the administrators and architects who run it.
Prairie Postgres, a nonprofit. UIC Student Center East, Chicago.
Conference · 22 to 23 October 2026
Great Lakes Software Symposium
Architecture, Kubernetes and web security sessions in Schaumburg suit a lead choosing a platform's foundations, and the online option spares the drive.
No Fluff Just Stuff. Renaissance Schaumburg Hotel, 1551 N Thoreau Dr, Schaumburg.
Conference · 10 to 11 August 2027
DevOpsDays Chicago 2027
Worth planning for next August at the UIC Forum, where two days on delivery and operations test whether your release process is as normal as you think.
Volunteer organisers. UIC Forum, 725 W Roosevelt Rd.

FAQ
Software development in Chicago: common questions
Do you work with Chicago companies?
Yes, and with companies across the United States. Arizona does not observe daylight saving, so we are one hour behind you from November to March and two hours behind from March to November. A morning standup on your clock is still early afternoon on ours.
Do you have an office in Chicago?
The office is in Gilbert, Arizona, with teams in Amsterdam, Dnipro and Hyderabad. Delivery is remote or hybrid, and we travel for discovery, workshops and the opening weeks of a build.
Can the event log serve as our reconciliation source?
That is what it is for. The event log is authoritative and read models derive from it, so a projection can be rebuilt by replay rather than reconciled by hand. In a business where reconciliation is a daily function that is the difference between an hour and a week.
What kinds of custom software do you build?
Web applications, mobile applications, APIs and the data platforms underneath them. The work we do best is the sort that has to be governed and auditable, where a wrong write is expensive and somebody has to be able to explain afterwards what changed and why.
Do you take over an existing codebase?
Often, yes. A good part of the work arrives as something already built that has become hard to change. We would rather read it and tell you honestly whether it is worth keeping than sell you a rewrite you may not need.
