Custom Software Development Company in New York City, NY

Because the local market is priced for banks. Experienced engineers in the city command salaries that make sense for a trading firm and not for a property manager, a nonprofit or a ten-person agency. Hiring takes months, and a single developer is a single point of failure when they leave.

An offshore team gives a company several engineers, a tester and a project manager for a budget that locally would cover one hire, and it can start within weeks. The trade is real, though. You give up the ability to sit beside the team, and you take on the need to write things down clearly.

The companies that do well with this model keep product decisions in New York and send the building offshore. Someone on your side owns what the software should do and why. We own how it is built, tested and delivered.

Control and evidence. Financial firms licensed in New York are subject to the Department of Financial Services cybersecurity regulation, known as 23 NYCRR Part 500. It requires a cybersecurity program, access controls, encryption of sensitive data, multi-factor authentication, audit trails and oversight of third-party service providers. A vendor that builds software for such a firm is one of those third parties.

In practice that means we are asked for specifics, and we provide them. Who can access the code and the data. How credentials are stored. How changes are reviewed and deployed. Where logs are kept and for how long. We work inside your cloud accounts with the least access necessary, use test data instead of production data wherever possible and document the controls built into the application.

We build to the requirements your compliance team sets. We are engineers, not auditors or lawyers, and we do not certify compliance.

Three come up most often. The SHIELD Act applies to any business holding private information about New York residents. It requires reasonable administrative, technical and physical safeguards and prompt notice if that information is breached. For a software product this translates into encryption, access limits, logging and a plan for incidents.

New York City's Local Law 144 covers automated employment decision tools. An employer or agency that uses software to substantially assist hiring or promotion decisions for candidates in the city must have the tool independently audited for bias each year, publish a summary of the audit and notify candidates. Enforcement began in July 2023. If you are building HR technology or adding scoring to a recruiting workflow, this shapes the design from the start.

The third is sector regulation: Part 500 for financial firms, described above, and HIPAA for health data. This is general information, and your attorney should confirm which rules apply to your product.

Real estate runs on information that changes daily: listings, availability, applications, leases, maintenance requests and commissions. Many firms manage it across a listing system, a CRM, spreadsheets and email.

Typical projects include a deal tracker that follows each transaction from lead to closing and calculates commission splits, a tenant portal for applications, documents and rent payments, a maintenance system that routes requests to supers and vendors, and reporting that pulls building data into one view for owners. Listing feeds are connected so that data is entered once.

As an illustration, a brokerage with forty agents might replace a shared spreadsheet with a web application where each agent logs deals, managers approve them and the accounting team exports commissions at month end. That is a few months of work and removes hours of reconciliation every week.

The city has one of the largest startup communities in the country, strong in fintech, health, media, commerce and enterprise software. Founders here are usually close to their customers and short on engineering time.

For a pre-seed or seed company we build the first version of the product: the smallest thing that lets real users do the core job. We agree the scope in a short discovery phase, with user flows and mockups, and then build in sprints with a demo every two weeks. The code is written in mainstream tools, React, Next.js, Node.js or Python and PostgreSQL, so that the engineers you hire after a funding round can take it over without a rewrite.

We are candid about what an outsourced team should not do. Product judgment, customer conversations and the technical vision of the company should belong to a founder or an early hire. We are most useful as the hands that build while you find that person.

New York's media and advertising companies deal in content and data at volume. Their software needs tend to be workflow and integration: editorial tools that move a piece from pitch to publication, rights and licensing trackers, campaign reporting that combines data from several ad platforms, and subscription or membership systems.

These projects are less about novel technology than about fitting the way a team already works. We spend time with the people who will use the tool before designing it, because a workflow system that ignores how editors or account managers actually operate is abandoned within a month.

Where a product includes AI features, such as summarizing documents or tagging content, we keep a person in the loop for anything published and log what the system produced, so that errors can be traced and corrected.

If you sell software or services to large New York institutions, you will receive a security questionnaire, often hundreds of questions long, before a contract is signed. Banks, hospitals and universities all send them. A product that cannot answer them does not get bought.

We build with those questions in mind. Single sign-on and multi-factor authentication. Role-based permissions. An audit log of who did what. Encryption in transit and at rest. Backups that are tested. A documented process for releasing changes. Dependency and vulnerability scanning in the deployment pipeline.

Many buyers will also ask for a SOC 2 report. That comes from an independent auditor and takes months, and we are not the ones who issue it. What we can do is make sure the application and infrastructure have the controls an auditor will look for, and help you assemble the evidence.

Pune is nine and a half hours ahead of New York in summer and ten and a half in winter. We use the overlap, 9 am to 1 pm Eastern, for conversations and the rest of the clock for building.

Every second week begins with a planning call. Your product owner and our lead agree which items from the backlog will be built, and each item has a written description and acceptance criteria. Through the sprint you get a short written update each morning and can see progress on a staging site. The sprint ends with a demo of working software and a discussion of what to change.

Questions that would block a developer are posted in a shared channel before our day ends, so you can answer them in your morning. A decision that sits unanswered for three days costs three days. Clients who reply promptly get noticeably more for their budget.

Your company owns it. The agreement assigns intellectual property to you, and every commit goes to a repository in your own GitHub or GitLab organization from the first day. Cloud infrastructure runs in your AWS, Google Cloud or Azure account, in a US region, and we are added as users.

We sign a non-disclosure agreement before you share anything confidential. At the end of an engagement, or at any point you choose, you remove our access and keep a complete, documented system.
