Software Development and IT Consulting for Philadelphia

PS3G provides IT consulting for Philadelphia organizations and builds the software that comes out of it: websites, web applications, mobile apps, .NET systems, cloud migrations, data platforms and AI. Our headquarters is in Wilmington, Delaware, about 30 miles down I-95 from Center City, close enough that a kickoff at your office is a morning’s drive rather than a flight. We work with organizations of every size: a University City startup with a first product to build, a Montgomery County distributor replacing an aging order system, or a department inside a health system that needs engineers who can work within its security and procurement rules.

Close enough to meet, remote enough to be efficient

Wilmington and Philadelphia sit on the same stretch of the Northeast Corridor. Our office at 1201 N Market Street is a straight run up I-95 to Center City, University City and the Navy Yard, and a short hop to the suburbs in Delaware, Chester and Montgomery counties. SEPTA Regional Rail and Amtrak connect the two downtowns as well.

That proximity shapes how we work. Discovery workshops, kickoffs and milestone reviews happen in person at your office when you want them to. Day-to-day delivery runs remotely: video calls, a shared backlog, a weekly written status note, and a demo at the end of each iteration. We do not keep a downtown Philadelphia office, and we do not pretend to.

Behind the Wilmington team is our delivery center in India, which gives Philadelphia clients 24/7 support and lets a team scale up for a release and down afterward. Architecture, project management and client contact stay in the US.

Services for Philadelphia organizations

Philadelphia’s economy is often summarized as “eds and meds”: universities, hospitals, research institutions and the companies that grow around them. Add the professional-services firms downtown, manufacturers and distributors along the I-95 and Route 422 corridors, nonprofits, and a steady stream of startups, and you have the range of organizations we hear from.

You need	What we deliver	Service page
A new or rebuilt website	Design, build, content migration, accessibility, and maintenance after launch, on WordPress or a custom stack	Website development
A mobile app	Native iOS and Android or cross-platform in React Native or Flutter, with the API behind it and store submission handled	Mobile app development
A web application or portal	Customer, patient or member portals and internal systems on .NET, Node.js or Java, connected to what you already run	Web application development
A plan before a build	An assessment, a technology roadmap and a written proposal for the first step	Technology consulting
Healthcare software	HIPAA-compliant apps, EHR integration over HL7 and FHIR, telehealth	Healthcare software development

Healthcare deserves a note in this city. We build and run our own HIPAA-compliant EHR and telehealth platform, DocVilla, so when a Philadelphia practice or health-tech founder asks for a HIPAA-ready build, they are talking to a team that operates one every day.

If you are comparing us with a web development agency in Philadelphia, the difference is this: we are a software engineering firm that also designs and builds websites, and we stay to maintain what we build. The same team that ships the site can connect it to your CRM or build the portal behind it.

Talk to us

Tell us what you are trying to do and we will reply with questions. The first step is a first conversation, then a short assessment and a written proposal with a fixed-scope quote where the work can be defined up front. Engagements run as a fixed-scope project, a dedicated team or staff augmentation, managed services under a defined SLA, or advisory. If you are on the Delaware side of the line, see our Wilmington headquarters page; South Jersey organizations may find the New Jersey page useful.

Frequently asked questions

Does PS3G have an office in Philadelphia?

No. Our headquarters is at 1201 N Market Street in Wilmington, Delaware, about 30 miles from Center City, and our delivery center is in India. We meet Philadelphia-area clients at their offices for kickoffs, workshops and reviews, and some prefer to come to Wilmington by car or train. Everything else runs remotely with a weekly written status note.

What does IT consulting for a Philadelphia company involve?

An assessment of the systems, vendors and risks you have today, a roadmap that sequences what to fix, replace or leave alone, and a written proposal for the first step. For a growing company that may be a technology roadmap; for an IT department, a modernization plan for a legacy .NET application or a cloud migration assessment.

Are you a web development company or an app development company in Philadelphia?

Both, and usually for the same client. A Philadelphia organization often starts with a website, then asks for the customer portal behind it, then the mobile app that reaches the same users. Because one team handles web, mobile and the APIs they share, the pieces are designed together rather than bolted on by different vendors.

Can you work inside a hospital’s or university’s security and procurement rules?

Yes. Larger Philadelphia institutions usually need vendor security reviews, their own tooling and access controls, and defined SLAs. We build and operate a HIPAA-regulated platform ourselves, so those requirements are familiar. Engineers can work under your accounts and standards as a dedicated team, and we can help with the documentation your procurement office asks for.

How is support handled after a project launches?

You choose: a managed service under a defined SLA, on-demand support, or a handover to your own team with documentation and a transition period. Our India center means an issue logged at the end of a Philadelphia workday can be worked overnight, with a US project manager as your point of contact throughout.
