Software Development and IT Consulting for Washington, DC

PS3G is a software development company serving Washington, DC and the surrounding Maryland and Northern Virginia region from its headquarters in Wilmington, Delaware, with a delivery center in India. We build websites, web applications, mobile apps, .NET systems, cloud migrations, data platforms and AI features, and we provide IT consulting for DC organizations that need an assessment and a roadmap before a build. There is no PS3G office in the District. Work is delivered remotely with in-person meetings by arrangement, and that suits organizations of every size: an association with a member portal to replace, a government contractor that needs engineers on a subcontract, or a department inside a federal agency, hospital or university with its own procurement and security rules.

How we serve Washington, DC without a local office

Our only office is 1201 N Market Street in Wilmington, Delaware, described on our Wilmington headquarters page. We do not maintain a DC, Arlington or Bethesda office, and we do not use a virtual address to suggest otherwise. Wilmington is a little over 100 miles up I-95 from the District, and Amtrak connects Wilmington station to Union Station in roughly two hours, so a kickoff, workshop or review at your office is a day trip rather than a flight.

Washington and Wilmington share Eastern Time, which means the whole US team is reachable through your business day. Our India center works during your night and hands off each morning, so build and test work moves while your office is closed.

Government and contractor work often needs in-person presence at specific moments: a requirements session with program staff, a system demo, a security walkthrough. We travel for those by arrangement and run everything else remotely: video calls, a shared backlog, a weekly written status note and a demo at the end of each iteration.

What Washington, DC organizations ask us for

The DC economy is government and the ecosystem around it: federal agencies, government contractors and systems integrators, trade associations and nonprofits, law and consulting firms, universities and hospitals, and the biotech corridor along I-270 in Maryland. The requests we hear follow that shape.

• Government contractors: engineering capacity on a prime’s contract for .NET, Java and cloud work; developers who work inside the prime’s tooling and under the agency’s security requirements; modernization of legacy applications. Where a role requires a security clearance, tell us early so we can confirm whether we can staff it.
• Associations and nonprofits: member portals, event registration, dues, certification and continuing-education systems integrated with an association management system or CRM, and accessible websites that meet WCAG.
• Federal agencies and their vendors: Section 508 accessibility remediation, cloud architecture that fits the agency’s authorization process, data pipelines and dashboards for reporting obligations.
• Law, consulting and advocacy firms: intranets, document workflow, client portals, and Microsoft 365 and Power Platform automation.
• Health and biotech along I-270 and in Bethesda: HIPAA-compliant applications, research data tools and EHR integration over HL7 and FHIR. We build and run our HIPAA-compliant EHR and telehealth platform, DocVilla, so HIPAA is part of how we work, not an add-on.
• Universities and hospitals: student and patient portals, internal systems, and engineers who can operate inside institutional security and procurement rules.

Government contractor software has its own vocabulary: task orders, deliverable acceptance, accessibility checklists, security plans. We work as a subcontractor or as a dedicated team under your direction, and we keep the documentation habits those contracts expect.

Engagements run as a fixed-scope project, a dedicated team or staff augmentation on a monthly cadence, managed services under a defined SLA, or advisory work such as an assessment, a roadmap or a fractional CTO. A Washington, DC founder usually starts with the first; a department inside a larger organization often needs the second or third.

How we start

The first step is a first conversation. If it makes sense to continue, we run a short assessment: a look at your current systems, a conversation with the people who will use the result, and a written summary of options. Then we send a written proposal with a fixed-scope quote where the work can be defined up front, or a team proposal where it cannot. The engineering is the same for a solo founder and for a division of a large company; only the scope and the engagement model differ.

Frequently asked questions

Does PS3G have an office in Washington, DC?

No. Our headquarters and only office is at 1201 N Market Street, Suite 111, Wilmington, Delaware, with a delivery center in India. We serve the District, Maryland and Northern Virginia remotely and travel for kickoffs, demos and requirements sessions by arrangement, usually by Amtrak to Union Station. We do not use a virtual DC address or a local forwarding number.

Is PS3G a software development company in Washington, DC or a remote vendor?

A remote vendor, and we say so plainly. Your project lead and architect are in the US, the build team blends US and India engineers, and meetings run over video during Eastern business hours. Because Wilmington is a short train ride from Union Station, in-person sessions are easy to arrange when a contract or a stakeholder group needs them.

What does IT consulting for a Washington, DC 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 Washington, DC company that may be a technology roadmap; for an IT department, a modernization plan for a legacy application or a cloud migration assessment. You can act on the recommendation with us or without us.

Are you a web development company or an app development company in Washington, DC?

Both, and often for the same client. A Washington, DC organization frequently starts with a website, then asks for the customer portal behind it, then the mobile app that reaches the same users. One team handles web, mobile and the APIs they share, so the pieces are designed together and maintained together after launch.

Do you build government contractor software or work as a subcontractor?

Both. We provide engineers as a subcontractor or dedicated team on a prime’s contract, working inside the prime’s tooling and the agency’s security requirements, and we build software for contractors themselves: proposal and capture tools, delivery dashboards, internal systems. We do not sell through a GSA schedule; if a contract vehicle matters, raise it on the first call.
