# Software development in Chicago, IL > 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. Canonical: https://www.techfabric.com/custom-software-development-chicago Serving: Chicago, Naperville, Evanston, Schaumburg, Milwaukee, Rockford Headquarters: 1530 E Williams Field Rd, Ste 201, Gilbert, AZ 85295. No office in Chicago. --- ## Why Chicago work is our work 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. ## Dynamics 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.

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. ## 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. ## Questions ### 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. ### 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. ## 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. ## Working with us from Arizona 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. Most delivery is remote or hybrid. We travel for discovery, workshops and the opening weeks of a build.
