Frequently Asked Questions About Software Development Services in Connecticut
What software development services does Longi Engineering offer in Connecticut?
Longi Engineering builds custom web and mobile applications, modernizes legacy systems, and develops SharePoint, Power Platform, and SQL Server-based solutions for Connecticut businesses, from initial architecture through post-launch support.
Should I build custom software or buy an off-the-shelf tool?
Off-the-shelf tools are faster and cheaper for standard workflows. Custom software makes sense when your process is specific enough that a generic tool forces you to work around its limitations, or when you need to integrate several systems into one. We can help you evaluate which fits during a free project scope call.
How much does custom software development cost in Connecticut?
Cost depends on scope, integrations, and complexity. A focused internal tool or Power Apps solution may cost far less than a multi-module case management platform. Longi Engineering provides a fixed-scope estimate after a free discovery call, before any development begins.
How long does a typical software development project take?
Simple internal tools and Power Platform solutions can launch in a few weeks. Multi-module custom applications, such as case management or compliance systems, typically take a few months. You’ll get a defined milestone schedule before work begins.
Do you provide post-launch support and maintenance?
Yes. Longi Engineering provides ongoing support, updates, security patching, and maintenance after launch, either as a standalone plan or bundled with managed IT services.
Who owns the source code once the project is complete?
You do. Longi Engineering delivers full source code ownership to the client at project completion, with no vendor lock-in on the codebase itself.
