Software Development and IT Consulting for San Francisco

PS3G is a software development company that serves San Francisco and the Bay Area remotely 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 San Francisco companies that want an assessment before a build. We have no San Francisco office. Delivery is remote, with in-person meetings by arrangement, and that fits organizations of every size: a founder with a first version to ship, a growing company whose core engineers are stretched, or a department inside a biotech, bank, foundation or university that needs engineers who can work within its rules.

How we serve San Francisco without a local office

Our only office is at 1201 N Market Street in Wilmington, Delaware, described on the Wilmington headquarters page. We have no office in San Francisco, Oakland, Palo Alto or San Jose, and we do not use a local mailbox or forwarding number to appear otherwise.

The Bay Area is on Pacific Time, three hours behind Wilmington. Our US team overlaps with your day from your early morning until about two in the afternoon, and recurring meetings sit in that window. The India team’s day begins in your evening, so work raised late in your day moves overnight and is reviewed by the US team before you start. Flights from Philadelphia to SFO take about six hours; in-person sessions are planned around kickoffs and major milestones.

Bay Area teams generally work in writing already, and so do we: a shared backlog, pull requests with written review, a weekly status note and a demo at the end of each iteration. Architecture, project management and your point of contact stay in the US.

What San Francisco organizations ask us for

The Bay Area has more software engineers per square mile than anywhere else in the country, so a company here hires an outside software development firm for specific reasons rather than for lack of local options. The requests we hear from San Francisco, the Peninsula and the East Bay reflect that.

• Founders and early-stage companies: a fixed-scope first version that is built to be extended, store submission handled, and a dedicated team when the product and funding grow.
• Product companies with a stretched core team: a second team that takes integrations, admin tools, data pipelines and QA automation off the core engineers’ plate, working inside your repositories and review process.
• Microsoft-stack work in open-source environments: .NET, Azure, SQL Server and Power Platform projects that an in-house team built on other stacks does not want to own.
• Biotech and healthcare: 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 our daily work.
• Foundations, nonprofits and professional services: websites connected to a CRM, grant and program management tools, and internal systems that replace spreadsheets.
• AI features with governance: assistants, document processing and agents added to existing products, with the policies and controls a customer’s security review will ask about.

Put simply, Bay Area companies work with us for capacity now, for a blended US and India cost structure, or for a stack their team does not keep. We are not trying to replace your engineering culture; we are trying to fit into it.

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 San Francisco 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 San Francisco?

No. Our headquarters and only office is at 1201 N Market Street, Suite 111, Wilmington, Delaware, and our delivery center is in India. We serve San Francisco and the Bay Area remotely and fly in for kickoffs and major milestone reviews by arrangement. We do not use a virtual San Francisco address or a local forwarding number.

Is PS3G a software development company in San Francisco or a remote vendor?

A remote vendor, three hours ahead of you. The project lead and architect are in the US, the build team blends US and India engineers, and we work mostly in writing with video calls in the overlap between Pacific and Eastern hours. In-person sessions are planned around moments that need everyone in a room.

What does IT consulting for a San Francisco 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 San Francisco 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 San Francisco?

Both, and often for the same client. A San Francisco 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.

Why would a Bay Area startup hire a software development company in Delaware?

Usually for one of three reasons. Capacity: a fixed-scope first version or a second team starts faster than a local hiring round. Cost structure: US leadership with India delivery changes the economics of a build without changing who is accountable. Stack: a founder or a department that needs .NET, Azure or Power Platform work in a company built on other tools. You keep the code, the accounts and the roadmap.
