App development · New York, NY
App development for New York companies
Your launch date is fixed, your users are waiting, and because the app moves money it also has to show an auditor who changed what. One senior team designs and builds the app and its API, ships on the date, and writes an audit trail with every change. In New York that's a lender's servicing app under the Department of Financial Services or an insurer's claims app, and a Brooklyn landlord's tenant app too.

New York runs on finance, from the banks and insurers answering to the state's Department of Financial Services to the fintechs that sell to them, with media, advertising and real estate close behind. Whatever you're building here, someone will eventually ask your system to explain what it did, whether that's an examiner, a client's auditor or a tenant's lawyer.
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 app development covers
iOS and Android
A shared codebase where it suits the product and native where it does not. It is a per-product decision rather than a house position, and anyone who answers it before hearing what the app does is telling you about themselves.
Web apps
The browser half of the same product, built to be changed safely years after the original team has moved on. Tests that mean something, seams where the business logic can move, a deployment nobody is afraid of.
The backend and API
Built with the app rather than found afterwards. Where you already have an API we will work with it and say plainly if it is the reason the app will feel slow.
Offline behaviour and sync
Decided deliberately at the start. A field app that has to work in a warehouse with no signal is a different design from one that assumes a connection, and retrofitting the difference means rewriting the data layer.
Release and store submission
Staged rollout so a bad build reaches a few hundred people rather than everyone, and the App Store and Play Store process including the rejections, which arrive for reasons that have nothing to do with code quality.
Keeping it alive
Two OS releases a year, certificates that expire while somebody is on holiday, and store policies that change. We stay on a maintenance footing or hand over with the provisioning and the release process written down.
The examiner arrives eventually
By 15 April each year, a bank or insurer regulated by New York's Department of Financial Services files either a certification of compliance with Part 500, its cybersecurity rule, or an acknowledgment of where it fell short, signed by its top executive and CISO. Section 500.6 asks for records that can reconstruct material financial transactions, and a public company answers to SOX as well. Both ask a system the same question: who changed what, when, and on whose authority.
Reporting jobs are how most firms answer it, which means a March spent pulling application logs into a spreadsheet that almost reconciles. We'd route every change to money or customer data through one path instead, and write the event that explains it in the same transaction as the change, so the trail can't drift from what happened.
The first two weeks go on finding every path that writes. We map the services, batch jobs and admin screens that can change a balance or a customer record, mark which ones leave evidence today, and give your CISO that map before any code changes. There's usually a writer nobody listed, a reconciliation script or a vendor's back-office screen, and closing it comes first.
Clients we have done this for
The LOSExpress rebuild for SWBC, a lending platform for credit unions, covered the user experience, the design system and the front-end architecture. Orders processed doubled and loan officers spent half the time on each order, which is what a lender or servicer wants to see before replacing a system its staff use all day.
Automotive / Fintech
SWBC
Credit union loan officers quote and book vehicle protection in SWBC's LOSExpress alongside a member's auto loan, but quoting was slow and new staff took too long to learn it. After gathering feedback from SWBC's staff and customers, our engineers and designers rebuilt one of its modules as a single-page application on a new design system. Orders processed doubled, and each loan officer now spends half as long on an order.
How an engagement runs
01
A technical conversation
Not a sales call. An engineer, asking what the app has to do, who uses it, what it talks to and what has been tried. Product and design people join the same conversation where the work needs them.
02
Two weeks, fixed fee
A short assessment ending in a written plan with a scope, a sequence and a number, including the decisions that are cheap now and expensive later. You own the document whether or not you carry on with us.
03
Build with your team in the repo
App, backend and release process together, senior throughout. The person in your standup is the person writing the code.
04
Ship, and keep shipping
Staged rollout, store submission, and either a maintenance footing with us or a handover with the provisioning and release process written down. The handover version only works if it was planned before launch.
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 New York
Android nights on West 19th Street
The New York Android Meetup gathers monthly on a weekday evening at Capital One's office on West 19th Street, with talks and hands-on workshops. iOSoho, the long-running iOS meetup, rotates between member companies' offices in Manhattan, and Flutter New York holds occasional evenings at Viam on the Upper West Side. GDG NYC runs workshops and hackathons on Google's tools, sometimes at Google's own office here.
In New York the app is often the front of something regulated, a lender's servicing app or an insurer's claims app, and the hard part sits behind the screen. Android developers meet in the Flatiron and iOS developers at iOSoho, which matters if you're choosing between two native apps and one Flutter codebase. Flutter New York's evenings at Viam are where to hear what a single codebase cost others.
The New York-Newark-Jersey City metro area. New York: Bronx, Kings, Nassau, New York, Putnam, Queens, Richmond, Rockland, Suffolk and Westchester counties. New Jersey: Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex and Union counties.

Meetup · Monthly, weekday evenings
New York Android Meetup
Hands-on workshops sit between the talks, so you can judge an Android developer's depth before hiring one or briefing a vendor.
Volunteer organisers. Capital One, 11 W 19th St, 3rd floor, Flatiron.
Meetup · Roughly monthly, weekday evenings
iOSoho
One of the longest-running iOS meetups around moves between member companies' offices, so every evening also shows how another team ships to the App Store.
Volunteer organisers. Rotates between host companies' offices in Manhattan.
Meetup · Occasional weekday evenings
Flutter New York
Weighing one codebase for iOS and Android? Ask at the Flutter evenings on the Upper West Side what that choice cost other teams.
Volunteer organisers. Viam, 1900 Broadway, Upper West Side.
User group · Several events a year
GDG NYC (Google Developer Group New York City)
Its workshops on Maps Platform and Gemini matter if your app will show a location or answer questions, since both bill by usage once you launch.
Google Developer Groups volunteers. Venues vary, including Google's New York office.

FAQ
App development in New York: common questions
Do you work with New York companies?
Yes, and with companies across the United States. Arizona does not observe daylight saving, so we are two hours behind you from November to March and three hours behind from March to November. That leaves most of your afternoon overlapping our morning, which is usually enough.
Do you have an office in New York?
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 you satisfy a NYDFS Part 500 review?
We build the evidence the review asks for as a property of the platform rather than as a reporting exercise. Every domain change passes one pipeline, the event that explains it is written in the same transaction, and the trail reconstructs rather than approximates.
What we do not do is certify you: your auditor does that, and our job is to make the answer easy to produce.
Native or cross-platform?
Cross-platform for most business applications, native where the product depends on something the platform does specifically. It is a per-product decision, and we will say which we think applies once we have heard what the app does.
Do you handle App Store and Play Store submission?
Yes, including the rejections. First submissions get rejected for reasons that have nothing to do with code quality, and knowing which ones are coming is most of what makes a launch date real.
